In bodybuilding, athletes wishing to lose fat purportedly use thermogenics to increase their basal metabolic rate, thereby increasing their energy expenditure. Caffeine and ephedrine are commonly used for this purpose. 2,4-Dinitrophenol (DNP) is a very dangerous thermogenic drug used for fat loss; it will give a dose-dependant increase in body temperature, to the point where it can induce death by hyperthermia. It works as a mitochondrial oxidative phosphorylation uncoupler, disrupting the mitochondrial electron transport chain. This stops the mitochondria from producing adenosine triphosphate, releasing energy as heat.
- Approximately all enzymatic reaction in the human body is thermogenic, which gives rise to the basal metabolic rate.
