Extract: Rats were restricted to 75, 50, or 25 percent of the food intake of control rats for 1 week and were subsequently pair-fed. Restricted rats gained weight at a slower rate and had less body fat at the end of the restriction period than control rats. Upon refeeding the same amount of food as consumed by the control rats, these rats gained more body fat than control rats. This compensatory fat gain occurred regardless of meal pattern. Both a high-carbohydrate and a high-fat diet produced compensatory fat gain. The results suggest that the initial food restriction inherent in many studies involving meal frequency may cause the subsequent increased food efficiency and greater accumulation of body fat often attributed to an alteration in meal pattern. Meal pattern has a minimal influence on body fat content provided the control animals are pair-fed throughout the entire experiment.
