Among the ways to lose weight quickly and effectively, the majority of people choose a diet. However, it is necessary to note that dieting is far from being the safest and most painless way to get rid of excess weight. After some diets, especially rigid and strict ones, the kilograms come right back and then weight continues to increase. Broken metabolism can be expressed not only in pathological adiposity, but can also be reflected in the endocrine, digestive, and nervous systems. The feeling of hunger that comes with a diet is one of the biggest stresses on the body. Because of that, there can be an increase in irritability, sharp mood swings, and a decrease in productivity.
