Altering portion sizes and eating rate to attenuate gorging during a fast food meal: effects on energy intake.

Objective: Eating large amounts of food at a rapid rate, defined as gorging, may contribute to excess energy intake. We aimed to evaluate whether altering portion sizes and eating rate could decrease energy intake during an extra-large fast food meal.

Methods: Subjects were adolescents (n = 18), 13 to 17 years of age, who reported eating fast food > or =1 time per week.

Effects of an ad libitum low-glycemic load diet on cardiovascular disease risk factors in obese young adults.

Background: The optimal nutritional approach for the prevention of cardiovascular disease among obese persons remains a topic of intense controversy. Available approaches range from conventional low-fat to very-low-carbohydrate diets.

Objective: The aim of this pilot study was to evaluate the efficacy of an ad libitum low-glycemic load diet, without strict limitation on carbohydrate intake, as an alternative to a conventional low-fat diet.
