Belly Fat: Harvard-Trained Doctor’s 3 Simple Fasting Rules
In a recent Instagram video, Harvard-trained doctor Saurabh Sethi explained three key steps to reduce belly fat with intermittent fasting.
Here’s what he recommends:
DON'T MISS
- Start with a 12-hour fasting window
Begin with a simple 10–12 hour fasting schedule. This is the easiest and most sustainable way to start. It also improves sleep and helps reduce late-night snacking, which often leads to weight gain. - Drink the right fluids during fasting
What you drink matters. During your fasting window, stick to low-calorie or no-calorie drinks like:- Black coffee, Green tea or black teaLemon water, Apple cider vinegar, and herbal teas like chamomile or ginger
- Focus on high-protein, high-fibre meals
Your eating window is just as important. Include foods that keep you full and support fat loss, such as:- Protein-rich foods: paneer, tofu, chicken, fish, chickpeasFibre-rich foods: fruits, vegetables, whole grains
Why Intermittent Fasting Helps Reduce Belly Fat
Intermittent fasting works by giving your body enough time to burn stored fat for energy. Over time, this can help reduce belly fat, especially when combined with healthy eating habits.
According to the Harvard T.H. Chan School of Public Health, intermittent fasting may support weight loss by improving metabolism and insulin sensitivity. Better insulin control means your body is less likely to store fat, particularly around the abdomen.
Experts also highlight that consistency is key. Small, sustainable changes often work better than extreme diets.
In simple terms, if you want to lose belly fat, focus on a balanced routine—controlled fasting, mindful eating and healthy lifestyle choices. These doctor-backed tips can help you get started without feeling overwhelmed.
