Effects of a low-glycemic load diet in overweight and obese pregnant women: a pilot randomized controlled trial.

Background: The optimal diet for pregnancy that is complicated by excessive weight is unknown.

Objective: We aimed to examine the effects of a low-glycemic load (low-GL) diet in overweight and obese pregnant women.

Design: We randomly assigned 46 overweight or obese pregnant women to receive a low-GL or a low-fat diet.

Effects of a low-glycemic load vs low-fat diet in obese young adults: a randomized trial.

Context: The results of clinical trials involving diet in the treatment of obesity have been inconsistent, possibly due to inherent physiological differences among study participants.

Objective: To determine whether insulin secretion affects weight loss with 2 popular diets.

Design, Setting, And Participants: Randomized trial of obese young adults (aged 18-35 years; n = 73) conducted from September 2004 to December 2006 in Boston, Mass, and consisting of a 6-month intensive intervention period and a 12-month follow-up period.

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.

A reduced-glycemic load diet in the treatment of adolescent obesity.

Background: The incidence of type 2 diabetes increases markedly for obese children after puberty. However, the effect of dietary composition on body weight and diabetes risk factors has not been studied in adolescents.

Objective: To compare the effects of an ad libitum, reduced-glycemic load (GL) diet with those of an energy-restricted, reduced-fat diet in obese adolescents.
