(NaturalNews) Trying to lose weight by eating foods with imitation fat substitutes and artificial sweeteners can actually be a cause of weight gain, according to a new study published online in the American Psychological Association (APA) journal Behavioral Neuroscience. According to researchers from Purdue University in Indiana, consuming low-calorie fat and sugar substitutes appears to actually induce weight gain rather than weight loss.
Dr. Susan Swithers, lead researcher, and her colleagues observed that test rats fed high-fat dietsactually fared better in the weight department than ratsfed low-fat, low-calorie diets. Using regular Pringles chips, which are high in fat and calories, as well as low-calorie Pringles, which contain olestra, an artificial zero-calorie fat substitute, the team observed that fake fats confuse the bodily response to food intake, and the body basically does not know what to do with these artificial substances other than to store them in thebody as fat.
In the end, rats that were fed only a high-calorie diet without any added artificial, low-calorie foods tended to remain smaller than rats that ate a high-calorie diet as well as the low-calorie Pringles containing olestra. In fact, whenever artificial, low-calorie Pringles were added to the mix of otherwise high-calorie diets, added weight gain was a result.
