I love coffee, and the other day I was realizing that I drink a lot of it.  I like my caffeine, and frankly it’s to the point where coffee actually really relaxes me.  It sounds contradictory, but I could drink a cup of coffee and then go to sleep whereas I really don’t sleep that well on a regular basis.  For a lot of people, caffeine of course causes jitters.  But theoretically at least, it’s supposed to in larger amounts like 400mg, speed up the metabolism while creating a thermogenic fat burning effect in the body. 

So the coffee I drink is actually rather concentrated to say the least.  I get about a 16oz can, which per serving has around 100 calories, so 200 calories total.  It has 1600mg strait caffeine per serving.  So you can imagine the ridiculous amount.  It is full of antioxidants due to the coffee element, and theoretically with that much caffeine on a regular basis, which is actually the only amount that really affects me in the energizing way at all, I should be burning fat like nothing else, especially with that few extra calories to actually actively burn off.  But I have nothing in that direction.  It does not burn fat for me, it does not result in automatic weight loss.  I should be a stick by now!  But that is one thing I think is a hoax in part for that reason.
