I once read a quote from Jessica Alba saying she had inherited fat genes from both sides of her family, meaning that she worked very hard to stay slim and trim.

Read below to learn which ones will help you turn on your fatburning switch. Some of my favorites listed include peanut butter and dark chocolate (especially together). What do you eat that helps you burn fat? Let us know in the comments below.
