Study: Carbs beat fats for appetite suppression

Carbohydrates Appear to Suppress Hunger Longer Than Fats

The popular notion that carbohydrates make you hungry while fat keeps you full is being challenged by newly published research.

In an animal study, rats fed a fat-rich diet produced more of an appetite-stimulating hormone than carbohydrate-fed rats, leading them to get hungrier quicker after eating.

The findings offer clinical support for the idea that different foods affect fullness differently. But studies in rodents don't necessarily tell us anything about hunger in humans, a hunger expert tells WebMD, and the researchers did not examine the impact of protein on hunger. Recent research in humans has suggested that protein helps keep you feeling full longer.

The strongest clinical evidence we have suggests that eating protein is associated with more feeling of fullness, California endocrinologist Francine Kaufman, MD, tells WebMD. "That is certainly the basis of protein-based diets, but this study does not address this. It does suggest, however, that the other main assumption of these diets -- the idea that carbohydrates are evil and should be avoided -- is wrong."
