OBJECTIVES This randomized controlled study was conducted to determine the effect of low glycemic index (GI) dietary advice on eating patterns and dietary quality in Asian patients with type 2 diabetes (T2DM). METHODS Asian patients with T2DM (N  =  104) were randomized into 2 groups that received either low GI or conventional carbohydrate exchange (CCE) dietary advice for 12 weeks. Nutrition...

BACKGROUND Low-glycemic index (low-GI) diets may be less nutritious because of limited food choices. Alternately, high-GI diets could be less healthful because of a higher intake of refined carbohydrate. OBJECTIVE The objective was to investigate the association between dietary GI, intakes of carbohydrates from high-GI (CHO(high GI)) and low-GI (CHO(low GI)) sources, and the risk of nutrient ...

UNLABELLED The glycemic index (GI) of a preexercise meal may affect substrate utilization and performance during continuous exercise. PURPOSE To examine the effects of low- and high-GI foods on metabolism and performance during high-intensity, intermittent exercise. METHODS Seven male athletes participated in three experimental trials (low-GI, high-GI, and fasted control) separated by appro...

OBJECTIVE Recent reports have suggested that a low glycemic index (GI) diet may have a role in the management of obesity through its ability to increase the satiety value of food and modulate appetite. To date, no long-term clinical trials have examined the effect of dietary GI on body weight regulation. The majority of evidence comes from single-day studies, most of which have been conducted i...

OBJECTIVE The use of diets with low glycemic index (GI) in the management of diabetes is controversial, with contrasting recommendations around the world. We performed a meta-analysis of randomized controlled trials to determine whether low-GI diets, compared with conventional or high-GI diets, improved overall glycemic control in individuals with diabetes, as assessed by reduced HbA(1c) or fru...

OBJECTIVE Evaluate the effect of glycemic index (GI) on biochemical parameters, food intake, energy metabolism, anthropometric measures and body composition in overweight subjects. MATERIALS AND METHODS Simple blind study, in which nineteen subjects were randomly assigned to consume in the laboratory two daily low GI (n = 10) or high GI (n = 9) meals, for forty-five consecutive days. Habitual...

Dumesnil et al. (2001) reported the results of a study from Laval University, Québec, in which overweight men were fed under metabolic ward conditions for 6 d on each of three different test diets. They concluded that: ‘. . . a lowglycaemic index–low-fat–high-protein diet can produce a marked decrease in ad libitum energy intake without increasing hunger or decreasing satiety while having rapid...

Background/Aim. Dietary glycemic index (GI) has received considerable research interest over the past 25 years although its application to pregnancy outcomes is more recent. This paper critically evaluates the current evidence regarding the effect of dietary GI on maternal and fetal nutrition. Methods. A systematic literature search using MEDLINE, EMBASE, CINAHL, Cochrane Library, SCOPUS, and I...

The choice of carbohydrate-rich foods in the habitual diet should take into account not only their chemical composition but also their ability to influence postprandial glycemia (glycemic index). Fiber-rich foods generally have a low glycemic index (GI), although not all foods with a low GI necessarily have high fiber content. Several beneficial effects of low-GI, high-fiber diets have been sho...

BACKGROUND Maternal diet is known to impact pregnancy outcome. Following a low glycemic index (GI) diet during pregnancy has been shown to improve maternal glycemia and reduce infant birthweight and may be associated with a higher fibre intake. We assessed the impact of a low GI dietary intervention on maternal GI, nutritional intake and gestational weight gain (GWG) during pregnancy. Complianc...
