3 tips to lose belly fat

According to the gastroenterologist, you can reduce belly fat with intermittent fasting by following these 3 particularly crucial fat loss tips:

1. Start with a 12:12 fasting schedule

According to the gastroenterologist, to reduce belly fat, you can start with a 12:12 fasting schedule intermittent fasting, which is the mildest option. It involves an eating window of 12 hours and a fasting window of 12 hours, for example, eating from 7 AM to 7 PM and fasting from 7 PM to 7 AM. This approach helps you sleep soundly at night and reduces the likelihood of unhealthy food choices the next day.

2. Fat loss drinks

During your fasting window, Dr Saurabh Sethi advised drinking only black coffee, green tea, black tea, water, apple cider vinegar, lemon water, fennel or basil water, chamomile or ginger tea.

3. High fibre and high protein diet

Lastly, he suggested focusing on a high-fibre and high-protein diet during your eating window. According to him, you can eat high-protein foods like paneer, tofu, chickpeas, chicken, turkey, and fish, as well as high-fibre foods like fruits and vegetables. This combination will keep you full and satiated while promoting fat loss.
