Low Glycemic Index Diet Promotes Weight Loss
Glycemic index is a measure of how was a food increases blood sugar. High glycemic index foods include simple sugars and white bread that enter the bloodstream quickly whereas low glycemic index foods include whole grains that are digested more slowly and trigger more modest increases in blood sugar. One theory is that rapid increases in blood sugar trigger greater insulin release which promotes fat storage.
British researchers found that middle-aged adults lost more weight following a low glycemic index diet than a high glycemic index diet during a 12-week study. Both groups reduced caloric intake by 300 calories below normal. The average blood sugar levels was lower in the low glycemic index group but there were no differences between groups in heart pressure risk factors such as blood pressure, cholesterol, or waist circumference.

Many of my clients follow a low glycemic diet and have very positive results in terms of weight loss. My 35+ females do especially well. I have found at times the need to cycle their carbohydrate intake or give them a high carb day during the week if they begin to plateau.
