Don’t Start a Diet Without This

Don’t Start a Diet Without ThisAll those who want to lose weight should know that the sleepiness is the best way to sabotage the decision to avoid food that causes gaining weight. Therefore, do not even think that you will be able to lose weight without regular good night rest.

A new research by the Harvard experts confirms the previous conclusions and recommendations of doctors about the lack of sleep when it comes to gaining weight and obesity.

US researchers were monitoring 12 people at the age between 19 and 45 who were sleepy during the day. After they showed them images with food high in calories, such as burgers, fries, pizza, cookies or ice cream, they realized that these individuals have a lower activity in the part of the brain that inhibits behavior (prefrontal cortex), as opposed to the brain activity when they watched images of healthy food.

“If you are sleepy, there are high chances that you will not be able to control the amount of food you eat. You can be attracted by unhealthy food because you cannot control yourselves, as opposed to the days when you are well rested,” explained William Killgore, a psychologist at Harvard.

Namely, the lack of sleep increases the levels of the hormone ghrelin, which controls our appetite and occurs when we feel hungry, while at the same time the level of the hormone leptin reduces, which signals to us the feeling of satiety. In case of insufficient sleep “there is less leptin and more ghrelin, which tells you to continue to eat, and your prefrontal cortex does not work so well as before and you cannot prevent overeating,” explained Dr. Shelby Freedman Harris, director of the Behavioral Sleep Medicine Program at Montefiore Medical Center in New York.

“Go to bed earlier every night, limit the intake of caffeine and alcohol, and try to do exercises five to six hours before going to bed,” advises Dr. Harris.
