People who daily use this spicy seasoning have a lower appetite, and also burn more number of calories. And if before a person did not like red pepper, and then introduced it into his diet, the effect of using it becomes the most powerful. Currently, scientists are working on a special pepper additive, which could be served up lunches and dinners and thereby burn unwanted pounds . Meanwhile, experts warn: those who sit on diets should pay more attention to the quality and duration of their night's sleep.
