Starvation mode: if your brain gets in your way
We have confirmation that it is legitimate to speak of ” starvation mode ” (“starvation” mode / “energy saving” mode) when the body is on a low-calorie diet.
According to research from the University of Cambridge , in fact, putting yourself on a low-calorie diet is useless, especially if the diet lasts more than a few weeks. Some spstanze produced by our brain in fact act on the hypothalamus (which also regulates the hormones of hunger and satiety) to reduce thermogenesis. Thermogenesis is how much we burn thanks to food (dietary thermogenesis) and thanks to the maintenance of body temperature.
The lower it is, the fewer calories we are consuming.
In poor words : when we are on a diet, the brain commands our body in order to make it burn fewer calories and push it to eat more. A phenomenon previously known as starvation mode .
This roughly thing was already known, what the researchers found is how it happens.
To prevent us from losing weight would be the AGRP neurons, which, once activated, trigger us hunger on the one hand, reduce the sense of satiety on the other. And they reduce all types of thermogenesis in the body, that is, they limit its energy functions and its efficiency in burning calories.
According to experts, restrictive diets don’t work in the long run – better to lead a healthy life all the time, just eating and moving more.
