In 2016, Anant Ambani, the youngest son of Mukesh Ambani and Nita Ambani, shocked the world by losing over 108 kg in just 18 months. 

What made this remarkable wasn’t only the number, but it was how he did it.

What Caused Anant Ambani’s Weight Gain?

Anant suffered from chronic asthma, a condition that often requires corticosteroid medications. These medications are essential for controlling inflammation in the lungs, but come with side effects such as:

• Increased appetite

• Slower metabolism

• Fat accumulation, especially around the face and abdomen

• Fluid retention and hormonal imbalance

Steroids interfere with the body’s normal energy regulation process. They alter how cells use glucose and fat, leading to higher fat storage even when the calorie intake isn’t excessive.

So, Anant’s early weight gain wasn’t just a lifestyle issue; it was medically influenced. His body’s metabolism slowed down, his appetite increased, and energy expenditure decreased.

This combination is what made his journey so significant: he had to fight not just habits, but also biology itself.

How Did Anant Ambani Lose 108 kg of Weight?

Between 2014 and 2016, Anant began a strict and supervised fitness journey. Under the guidance of renowned fitness trainer Vinod Channa, he followed a highly disciplined program that included:

• Balanced low-calorie diet (around 1,200–1,300 calories per day)

• Five to six hours of daily physical activity

• A combination of cardio, weight training, yoga, and meditation

The foundation of his success was consistency and gradual progress. He didn’t resort to shortcuts or surgical methods. Instead, he focused on slow metabolic adaptation, allowing the body to gradually shift from fat storage to fat burning.

What Was Anant Ambani’s Diet Plan?

Anant’s diet was highly structured but not extreme. It was designed to support both fat loss and muscle maintenance.

1. Calorie Control – The 1,200 Calorie Principle

He consumed around 1,200 calories per day, but the focus wasn’t just on quantity; it was on quality.

• His meals were nutrient-dense, not calorie-dense.

• Each calorie serves a biological purpose, from protein synthesis to gut health.

• He followed the caloric deficit rule: burn more than you consume.

2. Protein Priority

Protein was the central part of his plan, which is essential for maintaining lean muscle during fat loss.

• Sources likely included egg whites, lean chicken, fish, sprouts, tofu, and lentils.

• Protein also increases the thermic effect of food, meaning the body burns more calories during digestion.

3. Limited Carbohydrates, but Not Zero

Carbs were moderated, not eliminated. He likely consumed complex carbohydrates like oats, brown rice, and vegetables to fuel workouts. This helped maintain blood sugar balance and supported sustained energy release.

4. High Fibre & Hydration

Fibre from fruits, vegetables, and salads played a role in appetite control and digestion. Proper hydration supported cellular metabolism and prevented fatigue, crucial for long-duration workouts.

5. No Processed Foods or Sugary Drinks

Avoiding sugar and processed foods helped reduce insulin spikes, a key factor in reducing fat storage. From a nutrition standpoint, this diet structure works because it addresses three metabolic pillars:

1. Stable blood glucose

2. Adequate protein synthesis

3. Controlled energy balance

In short, Anant’s diet wasn’t about eating less, it was about eating right for his body’s biology.

What Kind of Workout Did He Follow?

Anant reportedly trained 5–6 hours daily, but not all in one stretch; his sessions were spread across the day for recovery and oxygen balance. Guided by trainer Vinod Channa, his goal wasn’t just to burn fat, but rather to retrain his metabolism and rebuild his body composition.

1. Cardio for Fat Burning

He began with low-impact exercises like walking and cycling to build stamina. Gradually, he progressed to high-intensity cardio, helping improve oxygen flow and fat oxidation.

2. Strength Training for Muscle Retention

Building muscle is crucial during weight loss. More muscle means a higher resting metabolic rate, allowing the body to burn more calories even at rest.

His sessions included:

• Compound lifts targeting large muscle groups (legs, back, core)

• Bodyweight exercises for stability and control

3. Yoga and Flexibility Training

Yoga played an important role in lung capacity and stress management, which is vital for someone with asthma. It improved circulation, oxygen flow, and mental calmness.

4. Meditation and Breathing Work

Meditation helped control cortisol (the stress hormone), which, when high, can trigger fat storage. Controlled breathing improved oxygen efficiency, which directly supports cellular metabolism.

Was Anant Ambani’s Weight Loss Naturally Achieved?

There were many speculations that Anant Ambani’s transformation involved surgery, but credible sources and his personal trainers clarified that it was entirely natural.

The process was guided by nutrition experts, fitness trainers, and medical professionals, ensuring a safe rate of weight reduction. He reportedly lost around 108 kg in 18 months, which is a result of discipline, not shortcuts.

What makes this transformation inspiring is that it followed scientific principles of calorie control, metabolic conditioning, and hormonal balance, the same pillars Immunosciences relies on while formulating its science-based supplements.

How Does Asthma Affect Weight and Fitness?

Asthma patients often rely on corticosteroid medications, which can increase appetite, cause water retention, and slow metabolism, leading to rapid weight gain.

However, with medical guidance and gradual training, it’s possible to overcome these effects. Through controlled breathing exercises, mild aerobic activity, and gradual intensity progression, it is possible to restore lung capacity and improve oxygen efficiency.

What Role Did Mental Strength and Family Support Play?

Weight loss isn’t only physical, it’s deeply psychological. For Anant, motivation came from family encouragement, especially his mother, Nita Ambani, and a disciplined lifestyle rooted in goal-setting.

Losing over 100 kg demands more than exercise; it requires emotional stability, willpower, and a strong support system. He stayed away from social distractions, avoided negative attention, and stayed focused on self-improvement.

From a scientific view, mental focus helps regulate hormones like cortisol and serotonin, both of which impact appetite and energy.

What Challenges Did He Face After Losing Weight?

Rapid weight loss comes with its own set of challenges, and Anant was no exception.

Some common issues include:

• Loose Skin: A result of rapid fat reduction, which may need medical or collagen-based support.

• Energy Fluctuations: Due to changing metabolism and hormonal adjustments.

• Maintaining Weight: Keeping the new lifestyle consistent after transformation.

• Muscle Retention: Ensuring lean mass is preserved to prevent rebound fat gain.

His continued focus on nutrition and strength training helped him maintain stability post-transformation.

This is where scientific supplementation, such as protein optimisation, micronutrient balance, and gut support, can play a vital role. Immunosciences emphasises sustained well-being, not just temporary transformation.

The Science Behind Weight Loss and Metabolism

To understand what happened during Anant Ambani’s journey, let’s simplify how metabolism works.

Metabolism is your body’s internal engine; it converts food into energy. When this system slows down due to a poor diet, low activity, or a hormonal imbalance, the body starts storing fat.

1. Metabolic Reset:

In the beginning, the body needs to switch from “fat-storing” to “fat-burning.” Controlled diets and light workouts triggered this change.

2. Thermogenesis Activation:

Regular workouts and nutrient-dense foods help the body burn more calories even at rest, a process called thermogenesis.

3. Muscle Preservation:

Strength training and protein intake ensure that while fat was lost, muscle was retained, which helps maintain metabolic rate.

This entire cycle shows how discipline and science-based nutrition can reprogram metabolism sustainably.

Why Sustainable Transformation Matters More Than Speed?

Losing weight quickly might sound exciting, but it often causes the body to rebound.

That’s why Anant Ambani’s transformation is respected; it took time and discipline, not crash diets or instant results.

Sustainable transformation focuses on:

• Gradual progress (1–1.5 kg per week is ideal)

• Hormonal balance (managing insulin, cortisol, and thyroid levels)

• Nutrient density (choosing foods that nourish, not just fill you)

• Lifestyle continuity (maintaining healthy habits long-term)

How Nutrition Science Supports Weight Management

Behind every transformation is the science of macronutrient balance, proteins, fats, and carbohydrates.

Let’s break it down simply:

1. Proteins: Help build and repair muscles, improving metabolism.

Best sources: Eggs, lentils, fish, soy, and pure plant-based protein powder

2. Fats: Support hormones and brain health; healthy fats like omega-3s aid fat oxidation.

Best sources: Nuts, seeds, olive oil, and specialised lipid-support supplements.

3. Carbohydrates: The body’s energy source, choosing slow-digesting carbs keeps energy steady.

Best sources: Oats, millets, fruits, and vegetables are ideal.

Micronutrients like vitamin D, magnesium, and B-complex also play a vital role in maintaining energy and preventing fatigue during weight loss.

The Role of Supplements and Protein in Sustainable Weight Loss

When someone loses more than 100 kg, the body goes through a massive recalibration. The metabolism, hormones, and muscles all need constant nutritional support, and that’s where the science of supplementation comes in.

Your diet should be rich in whole foods and protein sources that help:

• Preserve lean muscle mass while burning fat

• Repair tissues and joints after intense workouts

• Keep metabolism active even at rest

In a well-balanced program, supplementation you should include:

• Whey or plant-based protein for recovery and satiety

• Omega-3 fatty acids for reducing inflammation

• Multivitamins and minerals to support energy production

• Electrolytes and antioxidants to aid endurance and recovery

• Apple Cider Vinegar (ACV) to improve digestion and balance blood sugar.

These components help the body maintain the progress made during weight loss and prevent metabolic slowdown. A key challenge is after significant fat loss.

What Can We Learn from Anant Ambani’s Journey?

Anant Ambani’s transformation is not just about physical change, but it’s a scientific demonstration of how the human body adapts when given the right balance of nutrition, exercise, and consistency.

His weight loss wasn’t driven by extreme diets or shortcuts. It was powered by:
