In the pursuit of weight loss, many begin to closely monitor the state of hormones, but often become victims of fundamentally incorrect statements about their relationship. In our material, we put all the dots over i in this question.
Hormones are necessary for the full functioning of our body. They help regulate metabolism, immune and reproductive systems, mood, appetite. Hormonal imbalance can contribute to the emergence of health problems: anxiety, fatigue, depression, obesity. At the same time, there are many myths around the relationship between excess weight and hormones, which are dangerous primarily because they form a misconception about hormonal health. We understand how things really are, together with the endocrinologist-nutritionist, expert of the Grow Food service Stanislav Khan.
Myth #1: Hormonal disorders are the most common cause of obesity
If we turn to statistics, it becomes clear that the main cause of obesity is an energy imbalance, in which the caloric content of the diet exceeds the energy needs of the body. In 95% of cases, people gain weight due to poor nutrition and low physical activity, and only 5% due to diseases of the endocrine system.
Myth #2: Autoimmune thyroiditis is often manifested by excess weight
With autoimmune thyroiditis, the function of the thyroid gland decreases: the cells of the immune system perceive the organ tissue as foreign and begin to fight against it. As a result, the concentration of thyroid hormones in the body decreases, which are responsible for wakefulness, mental energy. They also control metabolism, enhance lipolysis and inhibit the formation and deposition of fat.
Autoimmune thyroiditis can cause weight gain. However, weight gain does not always happen, most often it is 3-5 kg, and then due to swelling of the tissues. In addition, the disease occurs in 3-4% of the world’s population, and about 30% suffer from obesity to one degree or another.
Myth #3: Insulin resistance is the cause of obesity
On the Internet, you can find a large number of tips from “nutrition experts” who call insulin resistance the cause of obesity and recommend treating it with a ton of dietary supplements. But the truth is that being overweight provokes insulin resistance, not the other way around. Currently, a large number of scientific studies confirm the relationship between obesity and the formation of insulin resistance. With an increase in body weight by 35-40% of the norm, the sensitivity of tissues to insulin decreases by 40%.
How does it work? Insulin regulates blood sugar levels and energy balance. It is secreted by the pancreas during meals. At this moment, brain cells read the signal, take nutrients and are saturated with them. With insulin resistance, the sensitivity of cells to insulin decreases, and they do not immediately respond to signals. As a result, the sugar level increases, and the feeling of hunger increases.
Myth #4: Increased prolactin inevitably leads to obesity
Prolactin regulates the formation of milk during lactation. The hormone is formed in the pituitary gland and stimulates the appetite of a nursing woman. Thus, she consumes more calories — for herself and the child “).
Indeed, increased prolactin can cause weight gain. But you need to understand that a high concentration of this hormone in the blood is a symptom of serious health problems. For example, pathologies of the brain, tumors of the pituitary gland, renal and hepatic insufficiency. Prolactin can also increase under stress and provoke puffiness.
The conclusion is simple: hormones can really affect weight, but still the main cause of obesity is a surplus of calories.
