Numerous studies have now shown how much more effective a low-GL diet is than other diets.
Scientific Evidence for the Benefits of Low GL for Weight Loss
Study 1 - Cochrane Review
The latest scientific review of 6 studies looking at the effect of low GL diets on overweight people has shown that a low GL diet is more effective than any other diet for weight loss and improving overall health.
‘Overweight or obese people lost more weight on a low Glycemic Load diet and had more improvements in lipid profiles than those receiving conventional diets.’ The review compared the results of six well designed trials comparing low GL diets with conventional diets based on reducing calories. Other benefits were greater loss in body fat, reductions in bad ‘LDL’ cholesterol, and increase in good ‘HDL’ cholesterol.
The authors looked at 6 studies involving over 202 overweight people either on low GL or conventional calorie controlled diets. The diets ranged from 5 weeks to 6 months in length.
Body mass, total fat mass, BMI (Body Mass Index), total cholesterol and ‘bad’ LDL-cholesterol all decreased significantly more in the low GL groups than in the calorie controlled diets.
This study highlights the importance and effectiveness of following a low Glycemic Load diet, not only for weight loss but also for improving cardiovascular health.

We conducted a trial, published in the Journal of Orthomolecular Medicine, placing twenty people on the Holford Low GL Diet, plus basic supplements (a multivitamin, extra vitamin C and omega 3 and 6 fats) for eight weeks. Four were unable to complete for personal reasons, leaving sixteen. The average weight loss was a highly significant 10.25lbs, equivalent to 1.3lbs per person per week. Body fat percentage dropped by an average of 2%. In addition, 94% reported greater energy, 67% had greater concentration, memory or alertness, 67% had less indigestion or bloating, clearer and less dry ......
