Fixed Dinner Time Matters More Than Early Meals, Says Gastroenterologist

New Delhi | 3 March 2026 Having dinner early is often advised for better health, but medical experts say consistency matters even more. A US-based gastroenterologist has explained that eating dinner at a fixed time every day helps the body function better by aligning it with its natural internal clock. While 6 pm is considered an ideal time, the focus should be on maintaining a regular routine rather than following a strict hour. Explaining the science behind this, Dr Palaniappan Manickam said the human body works on a 24-hour internal system known as the circadian rhythm. This clock controls hunger, energy levels, motivation, and hormone activity. Located in a small part of the brain, this “master clock” guides when hormones should become active or rest. According to the doctor, digestive hormones are most active during the day and slow down after sunset, while repair and growth hormones work mainly at night during sleep. When meals and sleep timings change daily, this balance gets disturbed, which can affect digestion, sleep quality, and overall health. He added that people do not need to force themselves to eat very early if it does not suit their lifestyle. Dinner at 9 pm is also fine, as long as it is followed consistently along with a regular sleep schedule. The key message from experts is clear: a fixed daily routine helps the body stay healthy and function Fixed Dinner Time Matters More Than Early Meals, Says Gastroenterologist Having dinner early is often advised for better health, but medical experts say consistency matters even more.
