Low glycemic index lunch on satiety in overweight and obese people with type 2 diabetes.

Several studies have shown that isocaloric diets have different effects on satiety. The aim of the present study was to compare the effect of lunches with different glycemic indexes (GI) in type 2 diabetics. Ten men and women with type 2 diabetes participated in the study. Subjects were given two experimental lunches with glycemic indexes of 43 and 88. Visual analogue rating scales were completed before and after each experimental meal periodically to record subjective feelings of satiety. Satiety Area Under the Curve was 1024 +/- 160 mm after the low GI diet and 711 +/- 190 mm after the high GI diet. Eating a lunch with a low GI index resulted in higher satiety perception. These results suggest the need to promote culturally based combined foods with high fiber and low GI. This approach might contribute to the prevention of obesity by increasing the perception of satiety while also improving metabolic control of diabetics. In addition, this is a low cost approach for people with limited financial resources.
