Weight lose diet are based on the calories you consume, not macronutrient, meaning they carbohydrates, protein and fat in the diet there. If it is true that their diets, for example, 1000 calories, which differ according to whether one of them more or less macronutrients.
That is why one can ask what is the difference between them and the truth is that if we relied on a study that was conducted in February 2009 in The New England Journal of Medicine by members of the Department of Nutrition, School of Public Health Harvard University there are not many, mostly because almost all lost the same weight whether they will use a diet rich in macronutrients or poorer in them.
This leads to the conclusion that there are macronutrients, that is, not what you eat what makes you gain or lose weight but how much of what you eat. If you eat less, your body when you run out of energy, has to burn more and therefore take reserves (ie, our weight) to compensate for the lack of energy. That is the reason that this, because you give your body more than necessary and, if you need more, has to use the reserves that have to do it.
Nor can we be blunt and say that macronutrients are useless, or it does not matter that we consume too much fat and carbohydrates, it’s okay, because it is not true, it does happen. Diets, although doctors give them to each patient, do not work equally for all. There are people who are overweight but not by eating hormone problems, and sometimes even without these problems. So, the best in these cases is to adapt the diet to the individual, not vice versa.
