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.
