Carbohydrates are only used for energy. They are not an essential - TopicsExpress

Carbohydrates are only used for energy. They are not an essential nutrient - our bodies can survive without eating them. (Not recommended at all Lol!) Protein and fat (along with vitamins and minerals) are used in all the other activities in the body, such as cell rebuilding and all the other processes we need to exist. Eating a diet too high in carbohydrates can still leave you malnourished, and even malnourished and fat. Not every calorie you eat is equal.
