Weight management for athletes and active individuals is unique because of their high daily energy expenditure; thus, the emphasis is usually placed on changing the diet side of the energy balance equation.

The ketogenic diet (KD) is widely used as a weight loss strategy and, more rarely, as therapy for some diseases. In many sports weight control is often necessary (boxing, weightlifting, wrestling, etc) but the KD is not usually considered. Our hypothesis is that KD might be used to achieve fat loss without affecting negatively strength/power performance.
