Coconut Oil: Diet Miracle or Fad?
Is it possible to add fat to your diet and lose weight? Yes, if it's the right fat, says naturopath Bruce Fife, ND, author of Eat Fat Look Thin. He recommends adding coconut oil and substituting it for polyunsaturated oils to suppress appetite, boost metabolism, and bring about weight loss.
"Lots of people have reported that when they add coconut oil to their diet, it was enough to promote weight loss," says Fife. "Some people don't notice a drop in weight, which often means they're simply eating too much. Calories are important." His own experience with coconut oil produced a gradual weight loss over six months of about 20 pounds, which he'd been unable to lose previously through diet and exercise.
He advises using about three tablespoons of natural coconut oil, either virgin or processed, daily. His patients use it in place of polyunsaturated fats for stir-frying and salad dressings, add it to other foods, or take it straight. The fat is also present in canned coconut milk (not the liquid inside the coconut), which can be substituted for milk in many recipes, and fresh coconut fruit, which can be eaten as a snack or grated over fruits and salads.
How Does Coconut Oil Promote Weight Loss?
"I think the real key to coconut oil and weight loss is the fact that it decreases your appetite while you're eating the meal and afterwards," says Fife. "Studies show that when these fats are added, people are satisfied sooner and eat less, and at the next meal they don't make up for it by eating more."
Coconut oil is a medium-chain triglyceride (MCT) while most other fats, such as vegetable oils and animal fat, are long-chain triglycerides (LCTs). "The length of the molecule determines how the fat is metabolized," says Fife. MCTs are rapidly broken down, and the body burns them much like carbohydrates for energy. LCTs, however, are deposited in fat cells. "With MCTs, you're eating fat calories, but you're eating fewer effective calories because metabolism rises, and you end up burning the calories, not storing them as fat. You can eat much more coconut oil than other fats before your body will convert it into fat."
Fife says that the types of oils present in coconut oil stimulate metabolism. "It promotes thermogenesis [burning of calories to produce heat], and some people with low thyroid function tell me they feel warm and their body temperature rises one or two degrees after eating coconut oil." People with low thyroid function have a low metabolism and can have a decreased ability to lose weight.
Can a Saturated Fat Be Good for You?
Coconut oil is highly saturated fat, which puts it in a class with animal fat. It's the oil banned from theater popcorn and denounced by the Center for Science in the Public Interest (CSPI). Foods found to contain coconut oil and other highly saturated fats end up in the CSPI newsletter's "Food Porn" category.
