Glycemic index and body weight

Weighing in on glycemic index and body weight.

This issue of the Journal includes a provocative observational study by Hare-Bruun et al (1) on a topic vigorously debated among scientists (2–9)—the role of the dietary glycemic index (GI) in the development of obesity. The concept of GI was developed by Jenkins et al (10, 11) at the University of Toronto more than a quarter-century ago as a physiologic, rather than a structural, approach to c...

Effect of glycemic index on satiety and body weight

Despite extensive study, the practical significance of the glycemic index of food is still debatable. The purpose of this review paper was to evaluate the effect of glycemic index on food intake and body weight based on the analysis of published studies about this topic. According to some authors, ingestion of high glycemic index diets tends to enhance appetite and promote positive energy balan...

Glycemic index and glycemic load of popular weight-loss diets.

CONTEXT Carbohydrate-restricted diets have been popular in recent years. The theoretical glycemic impact of these diets, compared with other popular weight-loss diets, has not been reported. OBJECTIVE To assess the glycemic index (GI) and glycemic load (GL) of 2 popular, carbohydrate-restricted diets (South Beach and Sugar Busters!) and compare them with a low-fat, high-carbohydrate diet (Orn...

Glycemic Index and Glycemic Load: Roles in Weight, Weight Loss and Satiety

Glycemic load, glycemic index, and body mass index in Spanish adults.

BACKGROUND Studies on obesity and glycemic index (GI) or glycemic load (GL) have had inconsistent results, perhaps in part because of underreporting or to heterogeneous dietary patterns across food cultures. OBJECTIVES We examined associations between body mass index (BMI) and GI or GL in a Mediterranean population, accounting for underreporting. We also constructed dietary factors related to...
