Good Fats vs. Bad Fats
If you want to get rid of fat in your body, put a little fat in your mouth. Seriously. The party line about reducing dietary fat to decrease body fat is finally losing ground. And not a second too soon — high-carb diets got us into a hormonal mess. (Don’t get me started on that again — go back to The Right Carbs for my rant.)
But don’t smother your food in butter just yet! Not every fat is going to improve your body composition. You need to know which fats to choose. And lucky for you, I’ve done my homework. Everything you needed to know about fat is right here.
GOOD FATS
Monounsaturated fats: These fats raise HDL cholesterol (the “good” kind) while lowering your LDL cholesterol (the “bad” kind), cutting your overall risk of heart disease.
Best choice: Extra-virgin olive oil
Omega-6 fatty acids: These polyunsaturated fats lower both HDL cholesterol and LDL cholesterol. Traditionally, they were assumed to be heart-healthy, but many sources of these fats (such as corn) can create eicosanoids, hormonelike chemicals that can lead to inflammation and blood vessel damage.
Best choice: Walnuts
Omega-3 fatty acids: These polyunsaturated fats lower both HDL cholestorol and LDL cholesterol, yet they’re extremely beneficial in reducing inflammation, the risk of heart disease and heart attacks, and possibly the risk of diabetes and bipolar disorder.
Best choice: Fish-oil supplements
NOT-TERRIBLE-BUT-NOT-GREAT FATS
Saturated fats: These fats raise HDL cholesterol and LDL cholesterol at the same time. Some researchers think their effects on HDL and LDL actually cancel each other out, so you're better off eating unsaturated fats whenever possible.
Best choice: Coconut oil
Trans fats from animal sources: The jury’s still out on these fats, which may lower body fat, LDL cholesterol, total cholesterol, and triglycerides but also increase insulin resistance and promote a fatty liver.
Best choice: Organic, pasture-raised beef
REALLY, REALLY BAD FATS
Trans fats from commercial products: These man-made fats raise LDL cholesterol, lower HDL cholesterol, increase inflammation, and are just plain bad for you.
Best choice: None! Stay away!
