Not So (O) Lean: Eating Faux Fat Makes Rats Real Fat

Sunday, June 26th, 2011

Another diet myth bites the dust: Products containing the calorie-less fake fat Olean, of fat-free potato chips fame, may make you gain weight, not lose it.

In a new study released today by Purdue University, researchers found that rats who were fed Olean-containing potato chips as part of a high-fat diet ate more overall and gained more weight than those who were fed a high fat diet and regular, full-fat potato chips.

This counter-intuitive finding shakes the conventional wisdom that substituting lower calorie, lower fat foods for the full-fat versions will help reduce overall caloric intake and encourage weight loss.
