WASHINGTON: The time of the day when food is consumed may
determine how many calories in it will be burned by the body, according to a
study which suggests that a daily fast between the evening meal and breakfast
can optimise weight management.
The researchers, including Kevin Kelly from Vanderbilt University, said the balance between weight loss and gain is predominantly determined by diet, the quantity of food consumed, and the amount of exercise a person gets. They said the time of the day when most food is eaten also determines how well a person burns dietary calories.
According to the study, published in the journal PLOS Biology, the human body’s daily biological clock and sleep regulate how the food is metabolised.

It added that the choice of burning fats or carbohydrates also changes depending on the time of day or night. The scientists said the circadian rhythm, or the body clock is programmed to assist the body burn fat when people sleep. As a result, they said, when people skip breakfast and then snack at night, it may lead to a delay in burning the fat.
Based on their observations, the scientists said the timing of meals during the day/night cycle may affect the extent to which ingested food is used versus stored.
According to the researchers, this study has important implications for eating habits, suggesting that a daily fast between the evening meal and breakfast may optimise weight management.
