Intermittent Fasting for Weight Loss: Benefits, Myths & How to Start

Intermittent fasting has become incredibly popular in India over the last few years. From fitness influencers to your colleague who skips breakfast, everyone seems to have an opinion about it. But there is a lot of misinformation floating around, and it is important to separate the facts from the myths before you try it yourself.

At DietGhar, we have helped hundreds of clients incorporate intermittent fasting into their routines — and we have also advised many others against it because it was not right for them. Here is an honest look at what IF actually is and what it is not.

What Is Intermittent Fasting?

Intermittent fasting is not a diet — it is an eating pattern. You alternate between periods of eating and fasting. The most common methods are:

• 16:8 method — Fast for 16 hours, eat within an 8-hour window (e.g., eat between 12 PM and 8 PM)
• 5:2 method — Eat normally for 5 days, reduce calories to 500-600 on 2 non-consecutive days
• 12:12 method — Fast for 12 hours, eat within 12 hours (the easiest starting point)

The idea is simple: by limiting when you eat, you naturally reduce calorie intake and give your body time to rest, repair, and burn stored fat.

Myth 1: Intermittent Fasting Is Just a Fad

The truth: Fasting has been part of Indian culture for centuries. Navratri fasts, Ekadashi, Ramadan, and various regional fasting traditions are essentially forms of intermittent fasting. What is new is the scientific research backing up the health benefits of these ancient practices.

Studies published in the New England Journal of Medicine show that IF can improve metabolic health, reduce inflammation, and even support brain function. This is not a trend — it is science catching up with tradition.

Myth 2: You Will Lose Muscle

The truth: This is one of the biggest fears people have, and it is largely unfounded. Research shows that IF does not cause muscle loss as long as you eat adequate protein during your eating window and do some form of resistance exercise.

Your body preferentially burns fat for energy during fasting periods, not muscle. In fact, fasting increases human growth hormone (HGH) levels by up to 5 times, which actually helps preserve muscle mass.

The key is to eat enough protein — aim for 1.2-1.6 grams per kilogram of body weight daily.

Myth 3: It Is Unsafe

The truth: For most healthy adults, intermittent fasting is safe. However, it is NOT recommended for:

• Pregnant or breastfeeding women
• People with a history of eating disorders
• Type 1 diabetics or people on insulin (without medical supervision)
• Children and teenagers
• People who are underweight

If you have any medical condition, talk to your doctor or a qualified dietitian before starting IF. At DietGhar, we always assess a client's health history before recommending any form of fasting.

Myth 4: You Will Be Hungry All the Time

The truth: The first 3-5 days can be uncomfortable, yes. But your body adapts surprisingly quickly. Most of our clients at DietGhar report that after the first week, they actually feel less hungry than before. Many say they have more energy and mental clarity during fasting hours.

Tips to manage initial hunger:

• Drink plenty of water, black coffee, or green tea during fasting hours
• Start with 12:12 and gradually extend to 14:10 or 16:8
• Stay busy — boredom triggers false hunger signals
• Eat filling meals during your eating window (protein + fiber + healthy fats)

Myth 5: You Can Eat Anything During the Eating Window

The truth: This is the most dangerous myth. IF is not a free pass to eat junk food. If you fast for 16 hours and then eat pizza, samosas, and ice cream for 8 hours, you will gain weight, not lose it.

What you eat still matters. During your eating window, focus on:

• Protein at every meal (dal, paneer, eggs, chicken, fish)
• Vegetables and salads for fiber and nutrients
• Whole grains over refined carbs (brown rice, millets, whole wheat)
• Healthy fats (nuts, seeds, ghee in moderation)
• Limited sugar and processed foods

Real Benefits of Intermittent Fasting

When done correctly, IF can provide genuine health benefits:

• Improved insulin sensitivity — your body handles blood sugar better, reducing diabetes risk
• Better brain function — fasting increases BDNF (brain-derived neurotrophic factor), improving memory and focus
• Cellular repair — fasting triggers autophagy, where your body cleans out damaged cells
• Reduced inflammation — lower inflammation markers linked to heart disease and arthritis
• Weight loss — primarily through reduced calorie intake and improved fat burning

How to Start: A Practical Guide

Week 1: Try 12:12 — finish dinner by 8 PM, eat breakfast at 8 AM. This is easy and you sleep through most of the fast.

Week 2-3: Move to 14:10 — finish dinner by 8 PM, eat your first meal at 10 AM.

Week 4+: If comfortable, try 16:8 — finish dinner by 8 PM, eat your first meal at 12 PM.

Listen to your body throughout this process. If you feel dizzy, weak, or irritable, you are pushing too hard. Ease back and try again gradually.

The Bottom Line

Intermittent fasting is a useful tool, not a miracle cure. It works best when combined with a balanced diet, regular exercise, and adequate sleep. It is not for everyone, and that is okay. The best diet is one you can sustain long-term.

If you are curious about whether IF is right for you, our dietitians at DietGhar can evaluate your health profile and create a customised plan. We do not believe in one-size-fits-all solutions — what works for your colleague might not work for you.
