There are so many diets out there always claiming that they are much better than the rest when it comes to muscle gain and fat loss. Interestingly, the key point in most of those advertised diets is how they use carbohydrates for building muscle and burning fat.
Athletes or fitness enthusiasts in general, are most likely to set up a diet plan containing of either high protein, high fat and low carbohydrates, or high protein, low fat and high carbohydrates. Even though both ways will be based on the total number of calories consumed (per day), they can both produce similar results of either building muscle or losing fat. The results of the diet plan followed will show themselves by the amount of food you eat and how much energy you are using per day (via training and other daily activities).
