Does caffeine increase metabolism? 
=================================
There is so much hype regarding fat loss properties of caffeine as it is presumed that it increases metabolism 
And yes it increases metabolism, but it does not have any fat loss properties. Now you must be thinking how? The simple answer to it is the number of extra calories burned due to caffeine is negligible. If you put one glass of water in an ocean does it increase the water level of the ocean? No right same way even if you add caffeine in diet, it does not result in any extra fat loss 
And also that increase in metabolism was observed at equal to more than 4mg/per kg body weight that is much much higher than the average consumption of caffeine
