Yes, low carbohydrate diets are healthy for individuals, because the American diet has too many carbohydrates in it. A diet that is low in carbohydrates allows a person to focus on making sure that they get enough fruits and vegetables. People can receive adequate nutrition in other ways, and in some ways, this is even healthier than a typical diet.
There are differing views on low-carbohydrate diets, however it is important to remember the science. Carbohydrates are used by our body to convert sugars to energy. Because it is important to pair healthy diet with exercise, the body needs energy to continue to function and heal properly. By denying the body carbohydrates, energy is created by converting fat or even muscle. While some may desire the body to use fat, it does not produce the same amount or same kind of energy in the same amount of time, and could be harmful to the body's recovery period.
