Fasting is an ancient practice that’s been gaining popularity once again. People are realising it’s not only about reducing calories, it’s about when you eat. From daily time-restricted fasting to once-a-week fasts, routines vary, but the benefits are clear if done thoughtfully.

At its core, fasting gives your digestive system a rest. Dr Balaji Laxminarayanshetty, Consultant in Medical Gastroenterology, Manipal Hospital Whitefield, says, “If you eat constantly or snack all day, your gut never gets a chance to reset. Gradually, this can disrupt your digestion. Fasting naturally reduces calorie intake, particularly from carbohydrates, which can lead to gradual weight loss.”

Speaking about the indirect benefits Dr Laxminarayanshetty, tells Moneycontrol, “The benefits include lowered risk of high blood pressure, diabetes, high cholesterol, and other metabolic conditions.” However, fasting, he says, is not the same for everyone. "Beginners can start with shorter fasts and work up to longer periods, listening carefully to their bodies along the way", he adds.

Fasting and mindful meal timing are tools to reset and rebalance your body. “Done carefully, they support gut health, weight management, and wellbeing. It’s not about following a fashion or punishing yourself,” says Dr Laxminarayanshetty. "It’s about giving your gut a break and working with your body’s natural rhythms", he adds.

Dr Laxminarayanshetty also explains why fasting works and what to keep in mind:

• Gives your gut a proper break: Fasting allows the digestive system to rest, repair, and function more efficiently. Even short fasting windows can help your stomach recover from constant food processing.
• Controls calories: By narrowing your eating window, you naturally eat less without extreme dieting. It’s about timing, not starving yourself.
• Include protein: “During fasts, your body may start breaking down muscle for energy,” says Dr Laxminarayanshetty. Make sure you eat enough protein during meals to protect lean mass.
• Start small and increase gradually: Beginners may try 6-hour gaps between meals, slowly extending to 8, 12, or even 16 hours. Longer fasts can boost fat burning but should be approached cautiously.
• Know when to be careful: Fasting isn’t safe for everyone. Diabetics on medication, those with heart disease, or other serious health conditions should consult a doctor before starting.
