In this edition of the HT Lifestyle series, ‘Internet vs Reality,’ we’re looking at a health claim that many of us come across online: walking after every meal helps burn fat . But does it really? And if losing weight were as simple as taking a post-meal walk, why would people spend hours working out at the gym?
HT Lifestyle spoke to Dr Soneet Yadav, ER Consultant, Ruby Hall Clinic, Pune, to separate fact from fiction and understand what science really says.
Dr Soneet highlighted that when you take a stroll after meals, your body does not immediately pull from fat stores. Rather, it changes how the body handles the food you just ate, which can have an indirect effect on weight and fat over time. Dr Soneet highlighted that when you eat food that contains carbohydrates, your blood sugar goes up, and the pancreas releases insulin to move that sugar into cells. High insulin acts like a lock on cells, telling the body to store energy instead of burning it. This cuts the blood sugar spike and keeps insulin lower. Lower insulin makes it easier for the body to use stored fat later. Physical activity moves food through the stomach and intestines faster, which can lower post‑meal sluggishness, bloating, and heartburn, making you feel more energetic. Pace: Keep it comfortable. Walking after meals may not instantly torch fat. As a daily habit, it sets a good hormonal environment for weight control and steady energy.
Timing: The best time to step out is within 15 to 30 minutes after finishing your meal, when blood sugar is usually rising. A casual stroll (about 2 to 3 mph) works; intense exercise right after a heavy meal can divert blood from the stomach and cause cramps or indigestion.
“When walking after a meal, the muscles use glucose directly from the blood for energy without needing insulin,” said Soneet.
