Eating after 10pm reduces calorie expenditure and increases risk of obesity, Harvard study says


According to research, eating late leads to increased production of hormones associated with the feeling of hunger

The time you eat for dinner can help you gain weight and have a hard time losing weight. This is what a new study of the Harvard University, in the United States. According to the research, published this week in the scientific journal Cell metabolism, people who eat after 10pm are more likely to develop obesity, feel hungrier the next day, and have a harder time losing weight. The reason is a change in metabolic pathways caused by eating late, close to bedtime.

The study involved 16 overweight or obese volunteers between the ages of 20 and 60. Half of them had their last meal of the day at 6pm, while the other half had their last meal of the day at 10pm. They received the same meal at their respective times and followed a strictly controlled routine before and during the search.

“Since our goal was to investigate the direct effect of meals, without confusing it with other behavioral and environmental factors, we rigorously controlled the time, amount and type of food intake, physical activity, posture, sleep and exposure to light, “explains the research report. “While this isn’t the first study to investigate the effect of late meals on the body’s energy balance, it may be the most well-controlled and complete.”

hormones

Participants recorded the level of appetite and hunger they experienced throughout the day and underwent blood tests, body temperature and energy expenditure. In this way it was possible to observe the effects of late meals on the control of energy intake and expenditure, as well as the molecular regulation of the metabolism of adipose tissue, where much of our body fat is stored.

The results showed that people who ate their last meal at 10pm produced more hormones associated with feeling hungry (ghrelin) and fewer hormones associated with feeling satiety (leptin) the next day than those who ate. the last meal at 6pm. Additionally, the 10pm group had fewer calories burned and more tissue samples indicating increased fat.

Obesity is a serious epidemic affecting approximately 650 million adults worldwide and is a major contributor to the global burden of chronic disease, the leading cause of death worldwide. In Brazil, according to the latest research published by Brazilian Institute of Geography and Statistics (IBGE)22% of men and 29.5% of adult women suffer from obesity.
