Is saturated fat bad for you?

Saturated fats are naturally occurring fats found in meat and dairy products. The problem with saturated fats is that when they enter your body, they tend to do the same thing they did when they were in a pig’s or cow’s body: Rather than be burned for energy, they’re more likely to be stored as fat in your flanks, in your ribs, even—ugh—in your loin.

In fact, they seem to have more of a “storage effect” than other fats. A new study from Johns Hopkins University suggests that the amount of saturated fat in your diet may be directly proportional to the amount of fat surrounding your abdominal muscles.

Researchers analyzed the diets of 84 people and performed an MRI on each of them to measure fat. Those whose diets included the highest rates of saturated fat also had the most abdominal fat. Saturated fats also raise cholesterol levels, so they increase your risk for heart disease and some types of cancer.

I don’t want you to eliminate saturated fats entirely; they’re heard of omega-3 fatty acids. They’re the fats found in fish, and a diet high in omega-3’s has been shown to help protect the heart from cardiovascular disease. That’s plenty enough reason to include seafood in your diet.

But new evidence suggests that this type of fat can actually help you control your weight. In one study, subjects who took in 6 grams a day of fish oil supplements burned more fat during the course of a day than those who went without. Researchers suspect that a diet high in omega-3’s actually alters the body’s metabolism and spurs it to burn fat more efficiently.
