There aren’t many things in this world I love more than peanut butter! (Except chocolate, of course) So when I found out natural peanut butter could help me lose weight, you can only guess how excited I got. Studies show that people who added 500 calories of peanut butter to their diet ate smaller portions at meals and increased their resting metabolism by 11%! If you like peanut butter, try to add in a tablespoon here and there and see if you notice a difference. Source: foxnews.com
