Ketogenic diets in weight loss: a systematic review under physiological and biochemical aspects of nutrition

ABSTRACT Countless strategies have been proposed to change dietary patterns to promote weight loss. Many of these strategies are controversial, with questions of effectiveness and possible negative consequences to health, even if weight loss effects are achieved. Ketogenic diets, with or without cal...
