Two distinct effects contribute to caffeine’s fat-burning properties: a thermogenic effect (in the short term, caffeine increases heat production) and a weaker lipolytic effect (in the long term, caffeine causes triglycerides to release fatty acids, which the body can then use for fuel).
More precisely, caffeine can increase the body’s levels of cyclic adenosine monophosphate (cAMP). Elevated cAMP levels are associated with lower triglyceride levels in fat cells and improved protein synthesis in muscle cells…
