So, I confidently decided to dig deeper into the science, compare nutritional facts, and bust the most common myths and educate my colleagues. Here’s why frozen vegetables are not only safe but often a smarter choice than fresh—especially when it comes to nutrient retention, convenience, and cost. (Disclaimer)

Frozen vs. Fresh: Which One Is Actually Healthier?

Many people assume that fresh vegetables are always superior, but research tells a different story.

• Flash-freezing locks in nutrients at peak ripeness, preserving vitamins and antioxidants.
• Fresh produce loses nutrients during transport and storage. For example:
  • Spinach loses 50% of its folate within 8 days at room temperature.
  • Green beans lose 45% of vitamin C after 7 days in the fridge.
• Studies show that frozen broccoli, corn, and blueberries often have equal or higher nutrient levels compared to fresh produce that’s been sitting on shelves.

The only downside, in my opinion, is texture changes in some vegetables, but the difference is minimal. So unless you can get fresh farm produce, frozen vegetables are equally nutritious.

Why I Prefer Frozen Vegetables (And You Might Too)

After years of using both fresh and frozen, here’s why I now stock my freezer:

• Year-Round Availability – Frozen makes non seasonal veggies available.
• No Prep Needed – Pre-washed, pre-cut—just toss into meals.
• Less Food Waste – Lasts 8-12 months vs. fresh veggies spoiling in days.
• Budget-Friendly – Often 30-50% cheaper, especially off-season.
• Perfect for Meal Prep – Use only what you need; no wilting leftovers.

Common Myths About Frozen Vegetables

Frozen Vegetables Are Less Nutritious Than Fresh

Freezing preserves nutrients better than long-haul transportation. A 2015 study in the Journal of Agricultural and Food Chemistry found that frozen fruits and veggies often had higher levels of vitamin C, polyphenols, and antioxidants compared to fresh-stored produce.

Frozen Veggies Contain Preservatives

Freezing is a natural preservation method—no added chemicals needed. Always check labels, but most frozen vegetables contain just the vegetable itself unlike frozen packaged food.

You Can’t Cook Frozen Veggies Without Them Turning Mushy

Proper cooking methods make a difference: Roast at high heat (425°F) for crispiness; Air-fry for a crunchy texture; Stir-fry directly from frozen (no thawing needed).

Best Frozen Vegetables To Buy (And Ones To Avoid)

Top Picks for Maximum Nutrition:

• Spinach & Kale – Retain iron and calcium well.
• Broccoli & Cauliflower – High in fiber and vitamin C.
• Peas & Edamame – Great plant-based protein sources.
• Bell Peppers & Onions – Convenient for quick cooking.

Avoid These (Unless Label-Checked):

• Vegetables with cheese/butter sauces (high in sodium and unhealthy fats).
• Seasoned blends with added salt/sugar (opt for plain versions).

In other words, don’t store packaged foods for long because they contain preservatives, fats, etc. Please remember, I am only talking about frozen vegetables, not frozen food.

Frozen vs. Fresh vs. Canned: The Ultimate Comparison

 Final Thoughts: Should You Switch To Frozen?

• Frozen wins for nutrition + convenience.
• Fresh is best if locally sourced and consumed quickly.
• Canned is okay in a pinch, but watch for sodium/sugar.

After years of using both, I confidently say: Yes, frozen vegetables are a smart choice. They’re nutritious, reduce waste, save money, and make healthy eating easier.

What is Intermittent Fasting?

Intermittent fasting is not about what you eat but when you eat. This is what I liked the most about it. You may eat what you want. It’s a time-restricted eating pattern that alternates between periods of fasting and eating. During the fasting window, your body undergoes several physiological changes that promote healing, fat burning, and cellular repair. Initially, I saw it as a simple routine change, however, as I delved into the science behind it, the more I realized its immense potential. The more time I gave to intermittent fasting the more I believed its claims.

My First Steps into Intermittent Fasting

Before starting my job, while I was preparing for exams, I began with the popular 16/8 method, which involves fasting for 16 hours and eating within an 8-hour window. It wasn’t easy at first—skipping breakfast left me sluggish, and the hunger pangs were distracting. However, by the third week, something shifted. My body started adapting, and I started feeling lighter, more energetic and I could concentrate more. This became my motivation.

The process didn’t just stop there. Over time, I experimented with other methods, including the OMAD (One Meal a Day) approach and 24-hour fasts. It’s my day off today while writing this and I can very easily manage eating once. That’s how far I have come. While these were initially challenging, the sense of accomplishment, clarity and strange euphoria I experienced was addictive.

Challenges I Overcame

Intermittent fasting wasn’t all smooth sailing, it was like climbing a mountain. In the early weeks, I faced:

Hunger Pangs: Drinking water, herbal teas, wheat grass juice helped immensely.

Fatigue and Irritability: This will test your limits. But stay committed.

Social Constraints: Skipping meals during gatherings was tricky, but I learned to schedule my eating windows strategically.

Overeating During Eating Windows: Some times overeating is okay when following one-meal-a-day plan. This is the beauty of it because you eat once a day. Just restrict your cheat days to 2-3 days in a month.

Besides my cheat days, I focus on nutrient-dense, whole foods to feel fuller and stay under my caloric limits.

Physiological Effects and Health Benefits I Experienced in My Body While Fasting

These are what I have experienced so far:

Fat Burning and Weight Loss

During fasting, insulin levels drop significantly, allowing my body to tap into fat stores for energy. Over a few months, I lost a significant amount of fat, particularly around my waist, while retaining muscle mass. How I maintained my muscle mass is by following my required macros. See my post on diet here.

Autophagy: Cellular Cleaning

One of the most exciting revelations was learning about autophagy, a process where the body cleans out damaged cells and regenerates healthier ones. This felt like a literal reset for my body—energizing and rejuvenating me from within. Now, while fasting, I feel a strong sense of healing—a feeling that my body is happy.

Reduced Inflammation

Intermittent fasting may reduce inflammation through various mechanisms, including cellular repair processes (including Autophagy) and shifts in metabolism. Recently, another diet trend has emerged, known as the Anti-Inflammatory diet. This diet solely focuses on eating foods rich in antioxidants and omega-3 fatty acids. I personally think IF (intermittent fasting) is much easier and fun than the anti-inflammatory diet because you can eat what you want (mindfully of course) and it provides many additional health benefits.

Enhanced Focus and Mental Clarity

The production of ketones during fasting was a game-changer for my brain. This is the biggest reason why I am still on this regime. I experience heightened focus and improved cognitive function, especially during extended fasts. It is like my brain switches to a high-performance mode.

Euphoria and Inner Calm

Unexpectedly, I started feeling a sense of happiness and calm during my fasts. This “fasting high” made the process enjoyable rather than restrictive, and I began looking forward to my fasting windows. Now I don’t even feel I am hungry for hours, It’s more like a happy body and happy mind time. I even workout while in fasted state in the morning for added benefits but I do take BCAAs while working out to prevent muscle loss. Please consult your doctor before trying this though.

Better Sleep

By limiting my eating window and avoiding late-night snacks, my sleep improved drastically. I wake up feeling refreshed and ready to tackle the day.

Long-Term Disease Prevention

Though I started intermittent fasting for weight loss, I realized its benefits go far beyond that. Studies suggest fasting improves insulin sensitivity, reduces the risk of heart disease, and may even slow the aging process.

Benefits According to Various Scientific Studies

There are also many other benefits of IF as per scientific studies and my research like up to 5 fold increase in Human Growth Hormone (HGH), reducing the risk of Type 2 diabetes, IF may reduce the risk of neurodegenerative diseases like Alzheimer’s and Parkinson’s.

Common Intermittent Fasting Methods

There are several IF methods like:

16/8 Method: My go-to for its flexibility. Skipping breakfast and eating between 12 PM and 8 PM was easy to stick with. This was what I followed when I was starting out.

OMAD (One Meal a Day): Perfect for resetting my system and enjoying one hearty, satisfying meal. I follow this on my days off.

5:2 Method: Ideal for busy weeks, where for two days you intake reduced calorie (500–600 calories).

Warrior Diet: Involves eating small amounts of raw fruits and vegetables during the day and consuming one large meal at night. I usually follow this on weekdays while on the job.

Alternate-Day Fasting: Alternate between normal eating days and fasting days (or very low-calorie intake). I have never tried this because I find this a little bit extreme and unnecessary.

Types of Foods to Eat During Eating Periods

Eating thoughtfully is important while IF for proper sustenance. I focus on getting the maximum nutrients from food as possible. I also take multi-vitamins apart from food. Please consult your doctor before starting any supplement.

Whole Foods: Vegetables, fruits, lean proteins, and whole grains. They will make you fuller with less calories.

Healthy Fats: Avocado, nuts, seeds, and olive oil. Don’t restrict fat intake. Fat hold equal importance in diet as fibre or protein.

High-Fiber Foods: Legumes, oats, and leafy greens. Fibres are important for good bowel movements and maintaining a healthy gut microbiome.

Hydrating Foods: Soups, broths, and water-rich fruits.

The Road Ahead

Today, intermittent fasting isn’t just a dietary pattern for me—it’s my lifestyle. The balance and control it gives me over my body and mind are unmatched. Whether it’s for weight management, mental clarity, or long-term health, IF has proven to be one of the most effective tools I’ve encountered. IF is not some starvation diet; rather, it is a structured fasting.

If you’re considering intermittent fasting, I encourage you to start small, remain consistent, and let your body guide you. You might just discover, like I did, that the true benefits go far beyond the physical—they touch every aspect of your life.

The post Beyond The Diet: My Unexpected Discoveries With Intermittent Fasting appeared first on FitPeakLife - Fit your Life, Peak your Potential.

Let me take you through everything I’ve learned—and experienced—about this incredible natural wonder.

What Exactly is Shilajit?

Shilajit is a sticky, tar-like substance that forms over centuries as plant matter decomposes under immense heat and pressure in the high-altitude regions of the Himalayas, Altai, and Caucasus mountains. What struck me first was its rich blackish-brown color and earthy smell—an indication of its mineral-rich composition.

It’s no surprise that this substance is considered a gift of nature. The meticulous process of its formation ensures that it’s packed with powerful organic compounds essential for health and vitality.

What Makes Shilajit So Potent?

The secret lies in its chemical composition. Since I was experiencing many positive changes in my health, I decided to look up what this wonderful herb consists. Here’s a breakdown of what I found out:

• Fulvic Acid: This antioxidant powerhouse helps fight oxidative stress, improve nutrient absorption, and enhance detoxification. This is a wonder compound in itself.
• Trace Minerals: With over 80 essential minerals (mind blown) like iron, magnesium, zinc, and copper, Shilajit supports various bodily functions.
• Dibenzo-alpha-pyrones: These compounds help stabilize energy production, keeping you feeling vibrant.
• Humic Acid: Known for its role in detoxifying the body and supporting gut health.

Traditional Uses that Inspire Trust

The history of Shilajit is deeply rooted in our ancient medicine. It has been classified as a “Rasayana” in Ayurveda, a term used to describe substances that rejuvenate the body and mind. Tibetan medicine also acknowledges its efficacy, especially for enhancing longevity and combating altitude sickness.

Knowing its rich history made me confident about incorporating it into my routine.

The Incredible Health Benefits of Shilajit

Through personal experience and extensive research, I’ve come to appreciate the versatility of Shilajit. Here’s how it can transform your health:

Energy and Stamina

Shilajit, by boosting our core function, provides a steady supply of energy. Whether it’s work or workouts, in recent months I have felt more sustained and less fatigued.

Hormonal Balance and Fertility

I have got my morning woods back! something I thought I might never experience again. For men, Shilajit is a natural testosterone booster. It not only supports muscle growth and libido but also enhances sperm health. It’s fascinating to see how a natural substance can positively influence male fertility and vitality.

Cognitive Boost

As someone who juggles multiple responsibilities, mental clarity is crucial. Shilajit’s fulvic acid combats oxidative stress in the brain, helping me stay sharp and focused throughout the day. I have noticed even after extended period of intense focus I am still left with mental strength in the evening. Its ability to enhance memory and learning is a bonus!

Stress Relief and Mental Health Booster

Consuming it lowers cortisol levels and help manage stress and anxiety.

Anti-Aging Properties

Who doesn’t want to age gracefully? Shilajit’s antioxidant properties fight free radicals, reducing visible signs of aging and improving skin elasticity. I have always looked younger for my age, and this is a added bonus.

Bone and Joint Health

Joint pain used to be an occasional nuisance for me. Thanks to Shilajit’s rich mineral content, I’ve experienced relief from inflammation and better mobility. It’s a natural ally for anyone dealing with arthritis.

Detoxification and Immune Support

Living in a modern world filled with toxins, detoxification is non-negotiable. Shilajit aids in removing heavy metals from the body while supporting liver and kidney health. It also strengthens the immune system, keeping illnesses at bay.

Relief from Altitude Sickness

Though I haven’t personally tested this, many hikers swear by Shilajit for its ability to improve oxygen transport and reduce symptoms like headaches and lethargy at high altitudes. Like I said Tibetians, Himalis (people who live in Himalaya) have already acknowledged its benefits.

How I Use Shilajit in My Daily Life

There are different forms of Shilajit available, but I prefer the resin form for its purity. Here’s how I incorporate it:

Dosage: A pea-sized amount dissolved in warm water or green tea an hour before bed. This simple routine has become a cornerstone of my wellness practice.

Consistency: Like any natural remedy, it requires regular use for noticeable results. See, in Ayurveda consistency is key. Because it’s all natural, your body need time for loading and processing. Missing a single day’s dose can set you back for weeks.

Precautions and Tips

While Shilajit offers incredible benefits, it’s essential to use it responsibly. Here are a few things I keep in mind:

• Choose Quality: Only purchase from reputable brands to avoid heavy metal contamination. I use dabur’s, a trusted brand in India.
• Watch for Side Effects: Overconsumption can lead to digestive discomfort. Start with small doses to see how your body responds.
• Avoid During Certain Conditions: Pregnant women and individuals with gout or excessive iron levels should consult a doctor before using Shilajit.

Common Myths Debunked

I’ve come across several misconceptions about Shilajit, probably because of its life changing benefits, but let’s clear some air:

• “Shilajit is a magic cure-all”: While highly beneficial, it’s not a substitute for a balanced diet and healthy lifestyle.
• “All Shilajit is the same”: Quality varies widely. Always choose pure, authentic sources.
• “More is better”: More of anything is bad. Stick to recommended doses to avoid side effects.

A Resolution for the New Year

As the new year has just begun, I invite you to join me in prioritizing holistic health. Let’s not just aim to exercise more or eat less junk food—let’s focus on nourishing our bodies with nature’s best, like Shilajit.

Whether you’re looking to boost energy, enhance mental clarity, or simply age gracefully, Shilajit offers something for everyone. It’s not a quick fix, but with consistency, it can be a transformative addition to your wellness journey.

Here’s to a healthier, stronger, and more vibrant you this year!

Let’s face it, no matter how many hours you spend at the gym or how many miles you run, your results will be limited if your diet is not aligned with your fitness goals. That’s why this year, I want to challenge you to make eating healthy your resolution. This is the foundation that will truly empower you to reach your full potential. (Disclaimer)

A Resolution to Eat Healthy

As much as we talk about setting up fitness routines or exercising regularly, the truth is, diet plays a much more significant role in the way your body responds. Exercise is essential, but without the proper fuel, your body will not perform at its best.

Here’s the key: food is fuel, and just like a car won’t run on the wrong kind of gas, your body won’t function optimally if you’re not eating the right foods. If your goal is to build strength, gain muscle, lose weight, or simply feel better overall, what you eat will determine how successful you are.

Why Nutrition Is the Most Important of Them All

Let’s break it down. When I say eating healthy, it’s not about extreme diets or fancy foods. It’s about getting the right balance of macronutrients that fuel your workouts and support your long-term health goals.

Protein: The Muscle Builder

Protein is crucial for muscle repair and growth. Whether you’re lifting weights or just aiming to stay lean and healthy, you need a steady supply of protein. Aim for 1.6–2.2 g of protein per kg of body weight daily.

Good sources of protein include lean meats like chicken, turkey, and fish, as well as plant-based options like tofu, lentils, and quinoa. Don’t forget to include protein shakes, which are a great option for quick, convenient protein.

Carbohydrates: Your Energy Source

Strength training and intense workouts require energy, and that energy comes primarily from carbohydrates. I recommend 4–7 g of carbs per kg of body weight daily. Complex carbs, such as oats, brown rice, quinoa, and sweet potatoes, will provide sustained energy to fuel your muscles during your workouts.

Healthy Fats: For Hormone Support

Healthy fats are critical for hormone production, especially for those looking to maintain a balance between strength and overall health. Your body needs 0.8–1.0 g of fat per kg of body weight to keep things running smoothly. Foods like avocados, nuts, seeds, and olive oil are excellent sources of healthy fats that you should incorporate into your daily meals.

Diet Is More Delicate Than Discipline

Think about it—waking up early or hitting the gym is primarily about setting a routine. But diet? It requires making conscious choices multiple times a day. It’s about saying no to tempting junk food, understanding portion sizes, and sometimes eating even when you’re not hungry to meet your goals (bulking, for example) or sometimes cutting calories to increase caloric deficit.

Micronutrients: Don’t Forget About These Little Guys

While macronutrients get the spotlight, micronutrients are just as important for muscle function and overall health. They are the core of proper bodily functions and macronutrients absorption. Here’s what you should be focusing on:

• Calcium and Vitamin D: Essential for bone strength and to help muscles function properly.
• Magnesium and Zinc: Crucial for muscle recovery and energy production.
• Iron: Helps prevent fatigue and supports oxygen transport in the blood.
• Potassium and Sodium: Help maintain electrolyte balance, especially when you sweat a lot during exercise.

Tailoring Your Diet to Your Goals

Now that we’ve covered the basics of macronutrients, let’s talk about how to adjust your diet depending on your specific goals.

Gaining Weight (Bulking)

If you’re looking to gain muscle, you need to eat in a caloric surplus. Aim for a 10–20% surplus above your maintenance level. Here’s how to split your macronutrients:

Protein: 20–25% of total calories

Carbs: 50–60%

Fats: 20–30%

Key foods include lean proteins like chicken, turkey, and whey protein, complex carbs like oats and quinoa, and calorie-dense snacks such as peanut butter and trail mix. The goal is to build muscle without excessive fat gain, so make sure you eat 5–6 meals daily.

Maintaining Weight

When you’re maintaining, your caloric intake should match your maintenance level, meaning the calories you consume equal the calories you burn. Here’s a good macronutrient split:

• Protein: 25–30% of total calories
• Carbs: 40–50%
• Fats: 20–30%

Focus on balanced meals with lean proteins, complex carbs, and healthy fats. Portion control will help you stay on track.

Losing Weight (Cutting)

To lose fat, you’ll need to be in a 10–20% caloric deficit. Protein becomes even more critical during this phase to preserve muscle mass, so aim for 30–35% protein in your diet. Carbs should be 30–40%, and fats around 20–30%.

Good choices include high-protein, low-calorie foods like chicken breast, white fish, tofu, and Greek yogurt. Non-starchy vegetables like spinach, broccoli, and cauliflower are excellent for filling you up without adding many calories.

Pre and Post-Workout Nutrition

Your workout nutrition is crucial, too. You need to provide your body with the right fuel before and after your sessions.

Pre-Workout

Eat 1–3 hours before exercise to fuel up depending on the meal you are taking. A great pre-workout meal might include grilled chicken, brown rice, and steamed vegetables, or a banana with peanut butter and a scoop of protein powder. If it’s easily digestible like peanut butter or protein powder then having it 1 hour before workout is fine. All this is good if you are aiming to maintain or gain weight but it is not helpful during cutting.

I usually drink a nice and strong espresso 30 minutes before my workout session and I drink BCAA while in the session. I will write a detailed article on this soon.

Post-Workout

After working out, you’ll want to replenish glycogen stores and kickstart muscle recovery. Within two hours of your workout, have a meal like a protein shake with fruit or a meal like salmon, quinoa, and asparagus. I am always on my toes so I prefer a quick protein shake to kickstart my day.

Supplements for Strength Training

These are gap fillers and very important. In this day and age, it is very difficult to get daily nutrition just from eating alone. While your diet should be the foundation of your nutrition plan, some supplements can help take things to the next level.

• Whey Protein: A quick, convenient source of protein.
• Creatine: Supports strength gains and muscle recovery. (Please consult your doctor first)
• BCAAs: Help reduce muscle soreness.
• Caffeine: Increases focus and endurance during workouts.
• Fish Oil: Reduces inflammation and supports joint health.

Remember, though, supplements should never replace whole foods. Always prioritize whole, nutrient-dense meals over pills and powders.

Final Thoughts: Keep Your Resolution Simple

As we step into a new year, it’s time to rethink how we approach resolutions. Fitness is not just about hitting the gym or running that extra mile—it’s about fueling your body to perform at its best. If you truly want to achieve your goals this year, make a commitment to eating healthy. Choose nutrient-dense foods that support your goals, and resist the temptation to take shortcuts.

You’ve got this. Stick to this resolution, and I promise, the results will follow. Let’s make this year the one where we not only work hard but also eat smart.

What is Metabolism?

When I first started exploring metabolism, I learned that it’s the sum of all biochemical reactions in the body. As I discussed in my other article, a calorie is the energy currency of life, meaning it provides the energy our body needs for metabolism. Metabolism is about how efficiently our body utilizes the calories we obtain from food. Metabolism occurs in two main forms.

Anabolism (Building Up)

This is where the body repairs tissues, builds muscles, or stores energy for future use. For instance, when we do strength training, our muscles undergo anabolic processes to grow stronger and larger.

Catabolism (Breaking Down)

This process releases energy by breaking down food molecules. Think about how your body digests a hearty meal after a long day, but catabolism is not limited to food alone. When there is a shortage of calories or your intake falls below your BMR (Basal Metabolic Rate), your body breaks down stored energy, which may come from fat or muscle. This is why people become thin as they eat less than what their body requires.

Components of Metabolism

All the following factors collectively contribute to the process of metabolism.

Basal Metabolic Rate (BMR)

This is the energy needed to keep basic functions going—like breathing or keeping the heart beating. BMR increases if you live a physically active life and have more muscle mass. This is because your body would need more energy or calories for building and repairing which we discussed in Anabolism.

Age also plays a major factor in BMR. As you age, maintaining the same level of fitness becomes challenging which declines BMR.

Thermic Effect of Food (TEF)

I love the fact that simply digesting food burns calories! For example, Protein-rich meals make my body work harder during digestion compared to carbs or fats.

Physical Activity

Well of course physical activity needs energy. Even simple tasks like taking the stairs or standing more contribute to calorie burn through Non-Exercise Activity Thermogenesis (NEAT). This is where Catabolism plays its role

Types of Metabolism in People

Often, two people with similar diets do not have the same physical build. This is because they have different metabolisms.

Fast Metabolism

Everyone has that person they know who eats all they want without gaining weight. This is because their metabolism efficiently utilizes energy consumed. This honestly bugs me a lot, I wonder God why not me.

Slow Metabolism

Here energy consumed is stored more than energy utilized. Naturally body does not utilize what it does not need and store energy as fat for a rainy day. The general idea is to increase your physical activity level and utilize more energy to burn more calories.

Factors Influencing Metabolism

Body Composition

Building muscle through strength training has been the most effective way for me to boost metabolism. Muscle burns more calories than fat, even at rest.

Diet

I once tried crash dieting and quickly learned it slowed my metabolism significantly. I was tired all the time, brain fog and what not. Lesson learned: consistent, balanced eating works best.

Sleep

When I don’t get enough rest, I feel sluggish the next day. There is more anabolic activity at night than during the day. So enough sleep is mandatory and non-negotiable.

Metabolic Disorders

During my research, I found that some disorders make it impossible for a person to alter or tweak with their metabolism.

Hypothyroidism

Metabolism slows down in this type of disorder and this often leads to fatigue and weight gain. Please consult your doctor for best course of action.

Diabetes

It is well known that diabetes is a disorder in which insulin is not efficiently regulated. This can make a person overweight or even thin as a stick. My shoutout to the world is that please just start doing any moderate physical activity and not wait for some disorder to strike first.

Boosting Metabolism

Based on my experience, strategies that work are

Dietary tweaks

Adding more protein-rich meals has kept me fuller longer while boosting TEF. Stay hydrated throughout the day and maintain a consistent balanced diet. Do not mix fasting and extreme dieting. While fasting is beneficial extreme dieting is not. Focus on nutrient dense foods, whole foods. Also maintaining your Gut Microbiome is very important. Incorporate fermented foods in your diet.

Exercise

Strength training builds lean muscles. And muscle mass improves metabolism since those muscles need calories for maintenance. Doing aerobic exercises also kick starts your metabolism and it stays elevated for a longer part of the day.

Lifestyle Adjustments

Practicing mindfulness and yoga helps me manage stress, which otherwise elevates cortisol and impacts metabolism.

Prioritize Sleep

At least 7-9 hours of quality sleep works wonders for energy levels.

Conclusion

Metabolism is dynamic and influenced by everything from genetics to lifestyle choices. While it may feel unchangeable, I’ve discovered that small, consistent adjustments can significantly improve how my body burns energy and maintains balance. Embrace the process—it’s worth it for a healthier, more fitter you.

What is a Calorie?

A calorie is a unit of energy. It is the amount of energy stored in a substance. In the fitness world, calories are measured by how much energy a food hold. However, just reading labels or estimating calories by portion size won’t help, I’ve lost many days and hours figuring out why my results were slow or non existent. Here is how calories are categorized :

• Gross Energy: The total energy in a food. The food may be raw or cooked.
• Metabolizable Energy (ME): The amount of energy our body can use after digestion. And digestion is not perfect to absorb all the calories.

This is the reason why some food may make you feel sluggish and some make you feel energetic. For example fats have higher ME than carbohydrates. ME is different for every person as their digestive system is different. You might be thinking that I am advocating fats, No. Please don’t confuse ME with metabolism.

ME provides the fuel for metabolic processes. The body uses the energy from ME to carry out various metabolic functions like building, repairing, discarding waste etc. Metabolism is different for everyone. It depends on age, genetics, physical activity.

Use of Calories

Like I’ve discussed calories are needed for metabolic functions. Our bodies constantly burn these calories for various functions. Below are a few ways our bodies utilize calories.

• Basal Metabolic Rate(BMR): The energy required for basic functions like breathing, circulating blood, maintaining body temperature and much more. BMR indicates basic amount of calories needed by our bodies in a day. Again, this depends on age, sex, physical activity etc.
• Physical Activity: This is what you do besides resting, I mean this is where calories besides BMR are utilized.
• Thermogenic Effect of Food(TEF): We normally don’t pay much attention to this. This is the amount of calories burned to digest and absorb the food. Yes, eating and digesting also costs energy. In other words TEF is required to produce ME(Metabolizable Energy).

It’s Not One-Size-Fits-All

We all have seen few people who eat whatever they want and how much they want and don’t gain weight. I, on the other hand, gain weight very easily. It turns out calories are individual specific. Some people have high metabolic rate so they need more calories than average.

Typically women need around 1600-1800 Kcal a day and men need 1800-2200 Kcal a day. Calorie requirement depend on one’s age, gender, height, BMR, physical activity, muscle mass etc. There are many platforms where you can calculate the number of calories needed to loose, maintain or gain weight.

Calorie Intake for Weight Goals

Besides your BMR, every calorie counts. Let’s see how

• Weight Loss: You have to be in calorie deficit for gradual weight loss meaning you have to burn more than you consume. Sounds simple but many people such as my old self go on hunger strike to consume less. See, burning calories and consuming less calories is different. You should anyhow eat as per your BMR for proper bodily functions and health. Eating any less may lead to malnutrition, brain fog, muscle loss, fatigue or worse. Calories deficit is calculated after consuming your required calories based on your BMR, say 1800 Kcal. Now suppose you go for a run or do some workout and let’s say you burn 500 Kcal then you are 500 Kcal in Deficit. 500 Kcal is roughly equal to 50 gms (0.11 lbs) of fat. And if you have eaten 2000 Kcal then for similar physical activity you will be 300 Kcal in deficit.
• Weight Maintenance: Account for your calories burned during a physical activity and add it to your BMR. That is your weight maintenance calorie.
• Weight Gain: It’s very easy!! I can do it in my sleep haha. Jokes aside, Eat more than you burn + BMR. But be goal oriented because many diseases are linked with obesity.

Calorie Quality vs. Quantity

Junk foods are tempting, but they pack bunch of calories for their small portion size. They don’t carry nutrients besides saturated fats and carbohydrates. With the little amount of calories that I have to spare for a day I want to be full and eat a nutrients packed meal. This is why quality matters over quantity.

• Empty Calories: Sugary drinks, processed snacks, alcohol are among the food and drinks which don’t offer much for health but fill your calorie meter very fast.
• Nutrient-Dense Calories: Foods like vegetables, fruits, lean proteins, and whole grains offer vitamins, minerals, and fiber. These are fulfilling and have low calorie per portion.

Macronutrients and Caloric Values

Understanding macronutrients helped me balance my meals better:

• Carbohydrates: 4 calories/gram. Carbohydrates are broken down into glucose and stored in our bodies. Glucose is further broken down to produce energy as needed.
• Proteins: 4 calories/gram. Essential for muscle repair and growth.
• Fats: 9 calories/gram. Long-lasting energy and critical for hormone production.

Balance, Quality, and Individuality

Calories are not the enemy—they’re a tool. By focusing on balance and quality, I’ve found a sustainable way to fuel my body and support my goals. Remember, your calorie needs are unique to you. Start small, track your intake, and make adjustments as needed. Your body will thank you and you will always be ready for a new day.

Claud, a 35-year-old software developer, spent most of his days hunched over a computer, immersed in deadlines and code. His sedentary lifestyle had taken a toll, but he brushed off the warning signs—weight gain, constant fatigue. Shortness of breath while climbing stairs or performing physically demanding tasks was an obvious sign, but he paid little attention to it, thinking his job was more important—or so he thought.

He thought he could always change and become a little active anytime and all shall be on track again. So, working to earn were the excuses among “I’m too busy,” or “I’ll start tomorrow.” But little did he know that he was getting late.

Call it fate or luck, but he went for a routine health check-up sponsored by his company. The doctor there informed him he was on the brink of Type 2 diabetes after conducting some tests. The diagnosis shook him to his core. I mean Claud knew his lifestyle wasn’t ideal, and his body had been signaling for change but he thought he had time and he was fine. Diabetes is a potential life-threatening condition. This diagnosis forced him to confront years of neglecting his health. Overwhelmed with regret, he decided to dig deeper.

He spent hours researching diabetes and what it meant to live with the condition. The facts were sobering. Type 2 diabetes could lead to, but is not limited to:

• Uncontrolled blood sugar levels that might require daily medication or insulin shots.
• Nerve damage (neuropathy) causing pain, tingling, or numbness, often in the feet.
• Vision problems, including diabetic retinopathy, which could lead to blindness.
• Kidney disease, potentially requiring dialysis.
• Heart disease and stroke, due to the increased strain diabetes places on the cardiovascular system.
• Delayed healing, with minor cuts or wounds potentially becoming life-threatening infections.

Claud realized he was staring down a future filled with limitations, medical expenses, and pain if he didn’t make immediate changes.

Ignoring anymore than this wasn’t something he could afford anymore. So, he let his fear fuel his resolve. His regret about ignoring his health turned into his motivation. 

He was determined to change so he started small. He began with short walks after dinner, which turned into brisk morning jogs. At first, running even a few minutes left him gasping for breath, but he stayed consistent. Each day, he pushed a little harder. Within weeks, Claud noticed improvements—not just physically but mentally. He felt sharper, more focused, and oddly, lighter in spirit.

He continued for around six months. His energy levels were at an all-time high. His doctor confirmed that his blood sugar levels had returned to normal, and he had dramatically reduced his risk of diabetes. Realizing the bullet he had narrowly dodged, Claud decided he would always find time to give to his body.

Over time, jogging turned into running, and running became his new found passion. He set milestones for himself, starting with a 5k marathon, then progressing to a 10k, and eventually conquering a full marathon in under four hours. Along the way, he shed over 25 pounds, replaced unhealthy eating with balanced meals, and inspired his family and colleagues to join him on fitness journeys of their own.

Today, Claud is the picture of health and a testament to the power of knowledge and perseverance. He often shares his story to motivate others, emphasizing how regret and knowledge can be powerful catalysts for change. He says, “Understanding the risks and consequences of neglecting your health can spark a life-changing transformation. Start small, stay consistent, and watch your life improve one step at a time.”

How does resistance training remodel bones?

Bone remodeling is a natural process where old bone tissue is replaced by new tissue. This process slows down with age, leading to a decrease in bone density and a higher risk of fractures. Strength training plays a key part to prevent this decline.

How it works

Strength training creates mechanical stress on your bones. This pressure triggers the activity of osteoblasts (cells that build bone) to lay down new bone tissue, enhancing its density and structure.

What’s fascinating is that this response is site-specific. For example, performing squats strengthens the femur, while pressing exercises fortify bones in the arms and shoulders. This means targeting different muscle groups during workouts can systematically improve your entire skeletal system.

Strength Training’s Role Across Different Life Stages

As you age the demand of your body changes. Let’s see what can be done and when

Young Adults

This is the prime time to maximize bone density because the skeleton reaches peak mass around age 30. Strength training during these years can lay a robust foundation for lifelong bone health.

Middle Age

By your 40s and 50s, bone density begins to decline. Regular resistance exercises can slow this process, helping to prevent osteoporosis and related fractures.

Seniors

Even in older adults, strength training remains effective. Studies show that it can reverse age-related bone loss and significantly reduce the risk of falls. For seniors, resistance bands or lighter weights can be a safe starting point.

Benefits of Strength Training for Bone Health

We have learned how bone remodeling works and how strength training places stress on bone tissue to trigger activity of osteoblasts. Let me show you some of its benefits.

Enhanced Bone Quality

Bone density is just one measure of bone health. The quality of your bones—such as their microarchitecture and ability to resist fractures—also improves with strength training.

Improved Balance and Fall Prevention

Strength training strengthens not only your bones but also the muscles responsible for stability. This dual benefit significantly reduces the likelihood of falls, which are a leading cause of fractures in older adults.

Prevention of Sarcopenia

Sarcopenia, or age-related muscle loss, often leads to weaker bones. By maintaining muscle mass through resistance training, you indirectly support bone health as well.

Hormonal Boost

Strength training triggers the release of hormones like testosterone and growth hormone, both of which play a role in bone remodeling.

Let’s compare Strength Training to Other Exercises

Don’t confuse strength training with aerobic exercises. While cardiovascular activities like running or cycling have health benefits, they don’t match the bone-building capacity of strength training.

The Nutrition Connection

Just doing strength training without proper diet is not going to make your bones stronger. How will osteoblast generate if they don’t get what they need. Proper nutrition plays the role of a middle man between training and bone health. Let’s see what you need for getting the most out of your workouts.

• Vitamin D and Calcium: Necessary for calcium absorption. Sunlight is a natural source, but supplements may be needed in areas with limited sun exposure.
• Magnesium and Zinc: These minerals support bone structure and repair. Nuts, seeds, and whole grains are excellent sources.
• Protein: Preferably animal based, protein is critical for collagen production, which forms the foundation for bone mineralization.

Concerns and Misconceptions

Does Strength Training Only Benefit Young People?

Actually, individuals in their 70s and 80s can see significant improvements in bone density and muscle strength through resistance training.

What About People with Osteoporosis?

Consulting a fitness professional or physical therapist is advised. Strength training is still beneficial but should be tailored to avoid high-impact movements.

Research Highlights

Strength Training and Osteoporosis Prevention

A meta-analysis published in Osteoporosis International found that resistance exercises significantly increase bone density in postmenopausal women.

Hormonal Impact on Bone Health

A study in The Journal of Clinical Endocrinology & Metabolism highlights how strength training boosts anabolic hormones critical for bone remodeling.

The Role of Nutrition in Bone Health

Research in The American Journal of Clinical Nutrition emphasizes the synergy between resistance training and adequate calcium and protein intake for optimal bone density gains.

Personal Prospective

Over the years, I’ve seen the transformative power of strength training—not just for my muscles but for my entire body’s structure. It’s humbling to think about how these exercises are protecting me from future issues like fractures or osteoporosis.

Building strong bones is about more than just health—it’s about ensuring independence and vitality as we age. If you haven’t already started prioritizing bone health, let today be the day you begin.

What is Creatine and How Does it Work

Creatine is a naturally occurring compound found primarily in our muscles and brain. It’s synthesized from amino acids—arginine, glycine, and methionine—by the liver, kidneys, and pancreas. About 95% of creatine is stored in skeletal muscle, with the remainder in the brain, heart, and other tissues.

Due to the dominant presence of creatine in skeletal muscles, it is evident that creatine holds importance. During short, high-intensity activities creatine replenishes adenosine triphosphate (ATP), the energy currency of our cells, enabling you to perform better during workouts. Creatine supplementation increases intramuscular creatine stores by 20–40%, leading to enhanced strength and performance.

Consuming creatine also creates a buffering effect. It means it delays muscle fatigue by buffering hydrogen ions that accumulate during intense exercise. Hydrogen ions are by-product of metabolic activities, which cause muscle acidosis and lactate production (Lactic acid). This makes it harder to exert force and generate motion. Some studies suggest that this can build endurance. So interestingly, creatine works as a buffer by drawing water into muscle cells, reducing the buildup of hydrogen ions. It also enhances cell volume and triggers muscle protein synthesis.

Types of Creatine

Creatine Monohydrate: The most researched, effective and widely used form and I have personally used only this.

Creatine Ethyl Ester: Marketed for better absorption, but lacks sufficient evidence.

Buffered Creatine (Kre-Alkalyn): Claimed to reduce stomach discomfort, though evidence is mixed.

Micronized Creatine: Finer particles for improved solubility.

Creatine Nitrate: Combines creatine with nitrates to improve vascularity and pump.

Sources of Creatine

1. The Body produces about 1-2 grams of creatine per day.
2. Dietary Sources: Found in red meat, fish (e.g., herring, salmon, and tuna), and other animal products. A pound of raw meat or fish typically provides 1-2 grams of creatine.
3. Supplements, Vegetarians and Vegans benefit the most from this since they lack dietary sources.

How Does it Benefit

We now know that a majority amount of creatine is present in skeletal muscles. And they replenish ATP during intense exercise to provide that boost. Let’s dive in a little more:

Athletic Performance

A meta-analysis revealed that creatine improves strength gains by approximately 8% and increases weightlifting performance by 14%. While this doesn’t sound much but practically the results are compounded, I’ll tell you how. Let’s say you can bench press 70Kgs/154lb. Consuming creatine can increase your weightlifting strength to 80Kgs/176lbs. Suppose you bench this weight for a month (assuming you hit gym 4 days a week ). Now your strength is adapted and you can move on to higher weights breaking your plateau according to your capacity. So 14% is more than it sounds.

The benefits are not limited to weight lifting. It enhances performance in sprinting, HIIT, cycling by providing the energy your muscles need to push harder during high-intensity workouts.

Cognitive Function

This is that 5% which is stored in brain, liver and heart. ATP is released in brain in a similar fashion as in muscles improving mental clarity, memory, and focus.

Health and Rehabilitation

Useful for preventing muscle loss due to aging thus maintaining that muscle mass and in recovery from injury.

Dosage

In the loading phase, you are required to take around 10-15gms of creatine, divided throughout the day. Personally I don’t recommend loading phase as many other suggest because you don’t know how your body will react to creatine and taking that much is just mental to me.

I recommend 3.5 to 5gms each day. It will take around 10 – 15 days but it’s worth it because you give your body time to adapt and if you see any side effects you can stop.

Please refer to your doctor if you have any medical condition before trying creatine. While it’s harmless as it is already present in your body but you never know.

Drink plenty of water to support creatine’s function and reduce potential side effects. Creatine doesn’t require cycling; I have been using it uninterruptedly for the past 2 years and I can say it is safe and effective. I even had my creatinine levels tested and they came well in healthy range.

Concerns/Myths Surrounding Creatine

Please be advised that I am not a medical professional. I am a fitness and nutrition enthusiast and I have given 12 years to this. What I write is all from my experience and research.

First, Creatine is not a Steroid. It’s a natural compound not a hormone.

Affect on Kidney: This is the primary reason many give up on even trying this wonderful supplement. I can say this confidently from personal experience that controlled dosage is not detrimental to kidneys though staying active is important. Concerns about kidney damage are largely unfounded in healthy individuals. Research indicates no adverse effects of creatine supplementation on kidney function when used responsibly but those with kidney or liver diseases should consult a healthcare professional before starting creatine.

Initial water retention can make some people feel bloated, but this is temporary and part of the muscle-building process. Safety Record: Creatine is one of the most studied supplements and is deemed safe for long-term use in healthy individuals.

Emerging studies indicate that women may respond differently to creatine supplementation, potentially due to hormonal influences like estrogen, which may already have protective effects on muscle and bone health. This could mean that women need tailored professional supervised dosages to maximize benefits. Pregnant women should always consult their doctor first.

My go-to Supplement: Creatine

Creatine has helped me push through tough workouts, recover faster, and even improve focus on those mentally draining days. It has helped me break plateaus, help with protein synthesis and stay consistent. I only take 3.5gms to 4gms a day and I am happy with the results. The science speaks for itself, and its versatility makes it a must-have for anyone serious about their fitness goals.

Heart Health: A Long-Term Investment

Aerobic exercise is among the most effective ways to protect your heart. When you engage in consistent aerobic activities—like running, cycling, or swimming—your heart adapts by pumping blood more efficiently and oxygenating your muscles with greater ease. Initially when I started running I felt choked, not because I was out of breath but because I felt pain in my arteries, I know it sounds farfetched but believe me the carotid arteries which goes through the neck stinged at every heart beat. Perhaps my arteries were contracted from prolonged inactivity and were now expanding. I’m not entirely sure, but the pain subsided after a few days of regular running. Unlike cardiovascular workouts focused on quick bursts, aerobic exercises maintain steady movement, allowing the heart to work at a consistent pace. Thus maintaining consistency can reduce blood pressure, lower bad cholesterol (LDL), and increase good cholesterol (HDL).

When I began incorporating daily 15-minute jogs before workout, I noticed fewer bouts of fatigue. The American Heart Association recommends at least 150 minutes of moderate aerobic activity per week for heart health, reinforcing how consistent effort reaps profound rewards.

Enhanced Endurance and Physical Stamina

Aerobic exercises focus on building endurance. Unlike high-intensity training that demands short bursts of energy, aerobic workouts strengthen the body’s ability to use oxygen efficiently over a prolonged duration. With each aerobic session, I noticed I could run longer distances without feeling winded, and climbing stairs no longer felt like a battle. Reaching a heart rate of 170 no longer feels challenging to me.

When starting this journey, I recommend gradually increasing the duration and intensity of your aerobic exercises over time. Walking can lead to jogging, and jogging can lead to running. This progression builds a robust cardiovascular system that supports other high-energy activities.

Weight Management and Metabolism Boost

Just think about it, if your heart rate is up for a longer duration during each session what will happen? Yes, engaging in aerobic exercise consistently supports weight management and boosts metabolism. Aerobic activities rely on oxygen to break down fat and carbohydrates into energy, providing a natural, long-lasting energy source.

Unlike purely anaerobic strength training or high-impact cardio sessions, which burn energy quickly, aerobic exercises provide a steady calorie burn. This is an easier way to lose weight than anaerobic workouts—you just have to be consistent.

During my experience, I found that moderate-intensity aerobic activities, like cycling and swimming, helped shed fat without the extreme fatigue of high-intensity routines. A mix of aerobic and strength training has been shown to maximize metabolism, offering benefits even after the workout ends.

Cognitive and Emotional Well-Being

A happy body leads to a happy mood. Aerobic exercise doesn’t just transform your body—it’s a lifeline for mental health. During aerobic workouts, endorphins flood the brain, relieving stress and boosting happiness. More significantly, aerobic training reduces the production of stress hormones like cortisol, creating a calm, relaxed mental state. Even on the toughest days, I’ve found solace in a simple 30-minute walk or run, which leaves me feeling uplifted and ready to take on challenges.

Furthermore, aerobic exercise can enhance brain function, improving memory and focus. Studies have shown that consistent aerobic training promotes neurogenesis—the formation of new brain cells—leading to sharper cognition.

Aerobic vs. Cardiovascular Training: Bridging the Gap

While every cardiovascular exercise is aerobic, every aerobic exercise is not cardiovascular. Aerobic and cardiovascular exercise share a connection in raising the heart rate, the distinction lies in intensity and oxygen consumption. Aerobic workouts, sustained over long periods, emphasize continuous movement, while cardio bursts focus more on immediate, high-energy spikes. As I shifted focus to aerobic training, I noticed steadier energy, improved endurance, and a more consistent approach to fitness.

Bone Health and Joint Stability

Not all aerobic exercises are high-impact, making them suitable for individuals who wish to protect their joints. Activities like swimming, elliptical workouts, or even walking ensure gentle, rhythmic movement, reducing joint stress. As someone who values longevity and joint health, I have found that low-impact aerobic sessions improve flexibility and mobility without the pain of joint strain. I mostly use the elliptical at high difficulty, and my heart rate reaches a whopping 200 in a matter of minutes.

Enhanced Blood Sugar Control

Aerobic exercise improves insulin sensitivity (read my blog on the benefits of walking after dinner here), allowing cells to utilize glucose more effectively, which can be essential for those managing type 2 diabetes or at risk of developing it. My energy levels remained more stable once I adopted daily aerobic exercise, reducing the mid-day energy crashes that come from spikes and dips in blood sugar levels.

Boosts Immune System Functionality

Well it’s common knowledge that a better metabolism leads to a better immune system. A healthy circulation system, supported by regular aerobic activity, helps immune cells reach areas of infection more efficiently. Since integrating consistent aerobic sessions into my routine, I’ve noticed faster recovery from illnesses and fewer occurrences of colds.

Building Strength through Coordination and Movement

When you start running you will feel the burn in the areas you did not feel when you were working out. This is because aerobic exercise improves the connection between muscle groups, helping to build stability, coordination, and controlled movements. While it doesn’t build raw power like resistance training, the balance and endurance gained from activities like cycling and aerobics significantly impact daily life tasks, from standing upright to lifting grocery bags.

A Balanced Approach to Aerobic Training

Incorporating different forms of aerobic training—whether cycling, swimming, walking, or dancing—adds variety and targets different muscle groups. It’s okay if you stick to any two, the choices are many besides what I mentioned. Personally I do cycling and running. The best aerobic routine is one that you enjoy and can stick to, as consistency will always bring the greatest rewards.

Final Thoughts: Making Aerobic Exercise Part of Life

Aerobic exercise isn’t just a temporary phase; it’s a lifestyle commitment that enhances every aspect of physical, mental, and emotional health. Whether it’s the rush of endorphins, weight control benefits, or heart health improvements, the benefits are countless.

Commit to even 20-30 minutes daily, and you’ll unlock a healthier, happier, and more energetic version of yourself. Your body and mind will thank you for the effort you put in and you will love the rewards.
