Do you know what leptin is?

As the title suggests, we are talking about one of the most important hormones for metabolism, albeit recently discovered (1996). Leptin is in fact a protein hormone that is mainly produced by adipose tissue and regulates the sense of satiety through the hypothalamus. It is not the only hormone that regulates satiety, nor is it the only determining factor. For example, insulin also regulates satiety, which is one of the reasons why I always say that you shouldn’t look at insulin as just the “fattening” hormone. And together with these hormones we also have the yy peptide and other substances that act in the intestine.

But leptin affects our metabolism in a unique way.

In fact, it raises the metabolism when we are full, allowing us more energy expenditure on the basis of the fact that we ate and therefore gave it some fuel. And it lowers it when we are fasting, so that we can survive with the reserves we have already given it. But this also means that we will be hungry.

More leptin equals higher metabolism?

Only from this brief explanation we can understand some things that can be useful for raising the metabolism. The more leptin we produce, the less we are hungry because we always feel without appetite or we tend to get full immediately; however, women produce more than men, and fat people more than thin people.
Theoretically, when a person gains weight , their leptin levels are high and tell the body that there is already a supply of fat, so there is no longer a need to introduce large amounts of food.

Since the metabolism is a self-regulating process, this mechanism should lead to weight loss in the person with fat reserves. However, this is not always the case. Because?
