3 Fats That Make You Skinny

2. Enova
Why it makes you skinny:
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.

When people on low-calorie diets consumed 15 percent of their daily calories from Enova (between three and eight teaspoons), they lost 1 percent more weight and nearly 3 percent more body fat than those who ate a similar amount of vegetable oil.

How to use it:
Enova's neutral taste makes it perfect for salad dressings. You can also bake and sauté with it, but don't use it for frying, says Kyle Shadix, R.D., of the Art Institute of New York City/New York Restaurant School, as it can change taste and color when overheated. One caveat: Enova is expensive — it costs about $6.65 for a 20-ounce bottle, compared to about $1.60 for the same size bottle of vegetable oil.
