Research showed that caffeine consumption increases fat oxidation rates and spares muscle glycogen. This led to the theories that A) caffeine is an effective fat loss supplement and B) caffeine is an ergogenic aid (performance enhancer) that increases your body’s ability to burn fat for energy.

Caffeine’s primary mechanism of action, however, is not metabolic. Rather, caffeine functions as a sympathetic nervous

system stimulant, increasing adrenaline levels.(type of hormone) , which alerts your brain to remain in active mode .

Caffeine can be performance enhancer when taken around  2  mg/kg   goes till 4 to 5 mg/kg  But tolerance(mean it became ineffective for  body )  to caffeine builds up quickly and at low dosages. Using just 1 mg/kg   to 3 mg/kg  induce  complete tolerance within 4 weeks
