Like being too thin, being too thin is a major mental problem that many people face today. When people struggle to lose weight, many people wonder what to eat to gain weight. The amount of food we eat is not the only thing that controls our body weight. This is due to the metabolism and some hormonal changes in our body. Here are the 5 main scientific reasons behind not gaining weight no matter how hard we try:
Fast Metabolism / High BMR: Some people have a very fast metabolism due to genetic reasons. That is, their body burns a large number of calories even when they are at rest. No matter how much they eat, their body burns those calories quickly without storing them as fat or muscle, which is why they are always thin.
Hyperthyroidism: This is a condition in which the thyroid gland in the throat produces more thyroid hormone than necessary. In people with hyperthyroidism, all body functions are accelerated. Although this causes extreme hunger, all the food eaten can be burned quickly, which can lead to rapid weight loss.
Malabsorption: This is a condition in which we eat well, but the intestines cannot absorb the nutrients in it into the blood properly. People with chronic indigestion, intestinal infections, celiac disease, and irritable bowel syndrome (IBS) do not absorb the food they eat and the body becomes thin.
Type-1 diabetes and anorexia: People with type-1 diabetes, which is caused by a lack of the hormone insulin, do not get glucose into the cells. At this stage, the body starts burning its own muscles and fat for energy. This can cause the body to lose weight quickly. Intestinal worms are another reason that rob us of the nutrients in the food we eat.
Anorexia / Stress: People with severe mental stress and depression often lose their appetite completely. Scientifically, this is called anorexia. When the body does not receive enough calories, the body naturally becomes thin.
