Endocrinologist told why people can eat a lot and not get fat

Weight gain or non-gain is influenced by factors such as metabolic rate, age of the person, sleep, diets, and various medications. In addition, any person has a certain genetic potential, which is still impossible to influence, RIA Novosti reports with reference to an endocrinologist, candidate of medical sciences Ekaterina Ershova.

Ershova explained that the metabolism is divided into the main – the energy that a person spends at rest to ensure the functioning of the body – and additional, which is associated with any activity. At the same time, the rate of basal metabolism in all people is different and is determined by many factors. In particular, it is affected by the available weight – with an excess amount of adipose tissue, the speed is lower. Muscle mass also matters – the more it is, the higher the metabolic rate, features of addition and age.

In addition, people who do not have problems with the quality and quantity of sleep are less likely to gain weight, since substances that affect appetite and satiety are produced in the corresponding centers of the brain according to a schedule predetermined by nature, the doctor emphasized. The composition of the microbiome, that is, the totality of microorganisms in the human body, also affects. The microbiome can deteriorate in particular due to the use of antibiotics.

And finally, “dietary history” is involved: those who endlessly use different diets, “as if they accustom their body to protection, defense, so every attempt to lose weight is given to them with great difficulty, ”Ershova emphasized.

At the same time, she advised even those who can eat a lot and still not gain weight to be sensible about nutrition, because sooner or later even good genetics can not cope under the onslaught of external factors that provoke weight gain.
