what kind of metabolic boost does caffeine give?

[Lao Tzu]

reading this article it states caffeine provides a 8-11% metabolic boost, which doesn't sound right. Can i get any other scientific verification that caffeine has such a strong boost on metabolic rate?

Also, what about taking low doses of caffeine more often. since caffeine has a 6 hour half life i'm thinking 200mg in the morning & 100 mg 6 hours later so it won't disturb sleep as much. i'd rather not go over 300 or so mg a day. if i take 200mg at 8am, 100mg 2pm and thats it that should provide maybe a 5-6% boost if the info in that article is correct. combined with the green tea i'm taking that should add up to a 10% or so metabolic boost, or another 360 calories a day.

Is say the metabolic boost would be 1% at the most!What a strange claim to make.T3 boosts the metabolism roughly by that amount.

That's what I was thinking! T3/clen boost your metabolism around 10%...Caffeine? Heh, doubtful...It is a nice supplement to have to get your daily boost, but 10% sounds a bit asinine, IMHO
