Drinking strong coffee before exercising increases fat-burning, new study finds

> Subjects ingested 3 mg/kg of caffeine or a placebo at 8am and 5pm

3mg/kg is over 250mg of caffeine for an average weight man. Twice a day makes that 500mg.

An 8.4oz can of Red Bull contains 80mg of caffeine. They were giving these people an amount of caffeine equivalent to 6 cans of Red Bull. Not a perfect comparison because Red Bull contains other ingredients, but that's still a lot of caffeine. For another point of reference, that's 2.5 shots of 5 hour energy (200mg caffeine per bottle).

To top it off, the subjects were caffeine-naive, so they had no caffeine tolerance. They must have been feeling extremely energetic.

No wonder they burned more fat. I'm not sure this is going to translate to your casual coffee drinker or someone with a high caffeine tolerance.

I quickly got addicted to Monster Energy drinks working at a Lowe's Hardware store across the street from a gas station; always been a caffeind. When the coffee ones came out I would do a 2 for and drink two during a break.

Anyway, at 21 I decided to use Jack3d, back when it was damn near Meth, it had DMAA in it. I didn't know this but being the 250lb 6' guy I was, slinging grills and landscaping stuff all day, I bucked up and took the "max dose" of it the first time.

Shit, I hit the gym, did extreme cardio on an elliptical for over an hour, lifted weights with some random ripped bros, and when my girlfriend came after work I stayed and ran further on the treadmill than her and her friend. Just the readouts from the elliptical and treadmill were almost 2200 calories.

Even afterwards when we went home I couldn't wait for us to shower before laying into her I still was so wired. A year later she was talking about that night...

Yea, I bet like hell someone that hasn't ever messed with stimulants can be turned sideways by them.
