Humans overeat over a long period of time. For example, members of the Masa tribe participate in the traditional fattening festival, as they try to gain as much weight as possible by eating the largest possible amount of food. Many individuals gained 11 kilograms of fat in just two months by eating 8,700 calories per day, which is more than three Double the daily recommended amount for adults.
Although this is an exaggerated example, it shows that our bodies are able to overeat, which is not necessarily a good thing. Even as little as 24 hours of overeating may have negative consequences for our health, such as elevated blood sugar levels.
According to the scientific site “ibelieveinsci”, this study focuses on knowing the amount that humans can eat after exceeding the point of satiety and fullness, and knowing the effect of that on the body, by measuring the effect of overeating on the metabolism during the hours after the meal.
The research was conducted on a group of 14 healthy men, between the ages of 22 and 37. In one attempt, they were asked to eat as much pizza as possible until they were satisfied, ate roughly 1,500 calories on average, which is slightly less than one large pizza.
On another day, they were asked to eat until they were completely filled, which goes beyond the normal feeling of satiety. At that time, they were eating almost twice as much, or about 3,000 calories on average, and some were able to eat the equivalent of 2.5 large pizzas (4,800 calories). This suggests that when you feel full or full, you are often only half full.
The ability to keep blood sugar and fat levels within a normal range indicates how healthy an individual’s metabolism is. It may also show a risk of developing diseases, such as type 2 diabetes or cardiovascular disease.
In the case of healthy, physically active people, it is possible for the body to control the levels of sugar and fats in the blood after eating a large meal, by working a little more effort than usual in order to control the process of metabolism. Hormones released from the gut and pancreas – including insulin – have been found to help the body regulate blood sugar levels. The heart rate also increased after the meal, confirming that the body was working harder to keep things under control.
Before starting the study, the researchers expected the body to experience huge caloric surpluses due to overeating. The results show the body’s remarkable ability to cope with the stress of eating a lot of food, by tightly regulating blood sugar concentrations and blood pressure. Historically, the human body has adapted to periods of famine and abundance, and this study is further evidence of this evolutionary adaptation.
