The science behind caffeine and fat-burning

The science behind caffeine Why less is more

Do you remember what you felt after your very first cup of coffee? Excitement and a remarkable ability to focus — maybe even euphoria.[1][2] Compare that with the “slightly less sleepy” feeling that followed your fifth cup this morning. Depressing, isn’t it?

So, what happened since that first, magical sip?

Caffeine tolerance

Found notably in tea and coffeecaffeine is the world’s most popular stimulant. In some people, it can promote anxiety,[3] but we usually associate a cup of coffee with happiness, and for some of us, even relief. Unfortunately, only people who aren’t used to caffeine will experience truly euphoric effects.[2][4] Chances are, if you’re a coffee lover, you’ll mostly experience caffeine’s awakening effect, not much else.

Drinking coffee just once a day is enough to increase your caffeine tolerance. And before you reach for that second cup, remember, caffeine tolerance is an insurmountable tolerance: At some point, taking more will just stop working. If you want to maximize the benefits of caffeine, you may want to try weaning yourself off it, to allow your tolerance to fade…

…3. Caffeine can help burn fat

Two distinct effects contribute to caffeine’s fat-burning properties: a thermogenic effect (in the short term, caffeine increases heat production)[19][20] and a weaker lipolytic effect (in the long term, caffeine causes triglycerides to release fatty acids, which the body can then use for fuel).[21]

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…
