Sleep more than 7 hours helps to lose weight? Science explains

If you started dieting and exercising but still could not lose weight know that there may be an explanation for this. Scientific studies suggest that to reduce calories one must pay attention to the amount of sleep that can influence weight loss.

According to a recent survey conducted by the British university King's College, although not all are affected in the same way, sleeping less than seven hours a night causes people to eat a lot more.

The BBC Trust program, I'm a doctor, performed a small experiment with four people to test this theory.

The analysis showed that the three volunteers who had sleep interrupted several times during the night, because of a toy baby pre-programmed to cry regularly, ate more than the usual at breakfast and / or chose less healthy foods. But the volunteer who slept well did not overdo it.

Researchers indicate that one night's sleep that is badly asleep can affect two key hormones related to hunger. Increasing the hormone ghrelin, which stimulates certain hypothalamic neurons, causing an increase in appetite. And by eliminating the hormone leptin, it sends a signal to the hypothalamus that the body already has sufficient reserves, that is, that we are satiated, and the appetite should be inhibited. In addition, other studies have shown that when a person is exposed to food in a state of sleep deprivation, there is a greater activation in areas of the brain associated with reward.

In this way, the person tends to choose foods with higher sugar and fat content, instead of other healthier options. All of these factors help to explain the connection between poor sleep, weight gain and health problems. For those who can not lose weight or maintain weight, considering increasing sleep hours is the researchers' top tip.
