Fat that helps you manage your weight and burn calories? You better read it to believe it.

Coconut Oil: is rich in a type of fat rarely found in other foods, called medium-chain triglycerides (MCTs). When you eat MCTs, they go straight to the liver instead of going directly into circulation where fat cells can suck them up.

Look for virgin coconut oil, don’t deep-fry it, and alternate it with other oils.

Enova: Traditional fats contain three fatty acids, but Enova, an oil, has just two, so your body treats it differently. It's processed in much the same way as coconut oil, traveling directly to the liver, where it's burned off and used for energy.

Don't use it for frying as it can change taste and color when overheated.

Nut Butters: Research has shown that people who eat nut butters often weigh less than those who shun them. It's likely that the combination of protein, fat and fiber keeps you full, so you'll eat less overall. And the unsaturated fat in peanuts and nut butters burns faster than other fats.

Use natural versions that are free of added oils and hydrogenated fats.

To get weight loss benefits, you have to substitute these for fat that's already in your diet, not add them to other bad fats. Yup, there’s always a catch!
