what foods will help speed up your metabolism?

green tea, they say spicy food does

these things are only temporary, very temporary, the best way to speed up your metabo is by gaining muscle it burns more cals per day then fat does. So working out and eating right is what it always comes down to.

adding muscle speads up your metabloism. This, combined with eating the right carbs and protein with every meal will help! But this goes for leverything-loosing weight, and just getting a healthier, better looking body. (This is the only formula I truly believe in)

Edited to say that I just came across this website. It has an article about grapefruit juice! It says it does spead your metabolism!
