Fatigue that gets worse all the time, or muscle cramps that form more and more, can be a sign of a lack of nutrients in the body. Diet is scientifically sound that can supply the body with nutrients in addition to energy. Merely eating bulky foods can not compensate for the lack of nutrients in the body. Nutrient deficiencies can have devastating effects on the skin, nails, hair and even the gums. Sometimes this deficiency is mistaken for a symptom of the disease, while the main reason is the lack of nutrients in the body. The notion that bulky foods provide nutrients to the body is a complete misconception.
