A friend of mine who also eats paleoly, also buys into all the get fit quick drug and supplements. (Colon cleansers and other snake oil.) He just started taking these thermogenic pills. He says they raise your body temp to make you sweat and give you energy. Im guessing its all in the name of burning calories. They don't seem safe to me snd it seems like all they do is make his skin red. Anyone know anything about this drugs/supplements? To me if your eating right you don't need energy pills and if you exercise you'll sweat.
