Or try high-intensity training, which shocks the body into releasing fat, and strength training, which counters muscle loss and can increase calorie-burning lean tissue.

It works by sending a low electrical current through the body, which travels more quickly through lean tissue than fat.

A diet too low in protein can result in losses in muscle mass and lean tissue.

If the athlete consumes too few calories for the body's needs, lean tissue will be broken down for energy and repair.

Creatine plus beta-alanine supplementation appeared to have the greatest effect on lean tissue accruement and body fat composition.
