The source of fuel to create this energy is the diet or, more technically, nutritional intake. The brain gets a biochemical message to reduce activity, and attempts to expend energy can cause increased weakness and fatigue. Nutritional status can be measured in several ways. Regular weighing is a rough measure. Energy is mainly stored in muscle tissue which, when measured, is known as lean body mass.
Dietary changes can help improve nutritional status.
Protein, fatty acids and carnitine are thought to be important dietary elements, and insufficient amounts can contribute to muscle fatigue. Certain vitamins and minerals have also been shown to be low in HIV-positive people and are often associated with weight loss and fatigue. These include low levels of vitamins B-12, A, and C, folate, carotene, and zinc. Through a proper medical evaluation, you can find out which dietary elements you are lacking and determine the cause of the deficiency. Working with an HIV-experienced nutritionist can produce an individualized nutrition plan to help address these deficiencies and combat fatigue.
