Body recomposition is commonly defined as the simultaneous process of reducing body fat while maintaining or increasing lean mass, frequently with no changes in total body mass. It has gained popularity in the exercise and sports nutrition field, particularly in the fitness and bodybuilding sector. Although body recomposition is a relatively new term, the scientific world has examined this phenomenon for decades. Researchers have studied and developed strategies to reduce fat mass (FM) while preserving skeletal muscle mass (SMM) and resting energy expenditure (REE) through the implementation of different types of exercise and diet intervention programs—for example, for the prevention and management of obesity (1).
