The question of what stimulates metabolism is often answered with simple 'fat burner' myths. Scientifically, metabolic rate is primarily influenced by lean muscle mass, physical activity, protein intake (thermic effect of food), adequate sleep, and healthy thyroid function. Genetic factors, such as variants in the leptin receptor (LEPR), can slightly modulate basal metabolic rate but are rarely the sole driver. Substances like caffeine, green tea, or capsaicin have measurable but usually small and short-lived effects. Many commercial 'metabolism boosters' lack sufficient evidence. A holistic approach including strength training, sufficient protein, and sleep is more evidence-based. MyBody-X tests can reveal genetic predispositions but do not replace medical evaluation for metabolic disorders. Caveat: Sudden unexplained changes in weight or metabolism warrant a doctor's visit.
