Even reduced-fat peanut butter still packs close to 200 calories and 12g fat into 2 tablespoons. That's why powdered peanut butter -- like PB2 and FitNutz Butter -- is the breakout food find of the century. It's made with defatted peanuts, so there's hardly any fat at all, and it's super-low in calories. Just mix 2 tablespoons of the powder with a little water, and you'll have creamy peanut butter with just around 50 calories and 2g fat. Use it as a spread or in recipes. It's a fantastic way to get peanut butter flavor you crave without a lot of calories or fat.
