Rationale: In order to create a positive energy expenditure, the number of kcalories consumed need to be increased and energy expended through physical activity should be minimized. Kcalories can be increased by increasing the amount of food consumed daily and enhancing caloric intake with high protein nutritional supplements. Alcohol consumption increases the number of calories consumed, but does not produce energy. Energy expenditure can also be decreased by avoiding unnecessary strenuous activity. Decreasing nutrient-rich foods could create a negative energy balance.
