Intermittent fasting continues to gain attention as an effective approach for weight management, and a US-trained gastroenterologist has now shared a simple method to make it more sustainable and belly-fat friendly. Dr Saurabh Sethi, a California-based gastroenterologist trained at leading institutions including AIIMS Harvard and Stanford, recently explained how a beginner-friendly fasting routine combined with smart food choices can support fat loss.
According to Dr Sethi, starting with a balanced 12-12 fasting method is ideal for those new to intermittent fasting. This approach divides the day into a 12-hour eating window and a 12-hour fasting window. He explains that this schedule supports better sleep patterns and helps reduce late-night snacking, which often contributes to stubborn abdominal fat.
During the fasting phase, Dr Sethi highlights that hydration is essential and allows for calorie-free beverages that do not break the fast. Suitable options include black coffee green tea black tea plain water lemon water apple cider vinegar fennel water basil water chamomile tea and ginger tea. Dairy and sweeteners should be avoided to maintain the metabolic benefits of fasting.
To maximise results during the eating window, Dr Sethi advises focusing on high-protein and high-fibre foods. Protein helps preserve muscle mass and keeps hunger in check while fibre supports digestion and prolongs fullness. Recommended protein sources include paneer tofu chickpeas chicken turkey and fish along with a variety of fruits and vegetables for fibre intake.
Dr Sethi emphasises that consistency and mindful choices matter more than extreme restriction. He also reminds viewers that intermittent fasting is not a one-size-fits-all solution and individuals should consult a healthcare professional before making significant dietary changes.
