Fat substitutes could make you gain weight
A new study has revealed that foods made with fat substitutes do not help with weight loss. The study by researchers at Purdue University showed that synthetic fat substitutes used in low-calorie potato chips and other foods could backfire and contribute to weight gain and obesity.
`Our research showed that fat substitutes can interfere with the body`s ability to regulate food intake, which can lead to inefficient use of calories and weight gain,` said Susan E. Swithers, the lead researcher and a Purdue psychology professor.
The study used laboratory rats that were fed either a high-fat or low-fat diet of chow. Half of the rats in each group also were fed Pringles potato chips that are high in fat and calories.
The remaining rats in each group were fed high-calorie Pringles chips on some days and low-calorie Pringles Light chips on other days. The Pringles Light chips are made with olestra, a synthetic fat substitute that has zero calories and passes through the body undigested.
