A low glycemic diet does not increase weight loss compared to a high glycemic diet according to a new study from the U.S. Department of Agriculture. Diet

Calories restricted by 30%

People were given a diet that was 30 percent below their needs.

 

Food

Food given to subjects for the first 6 months

For the first 6 months, subjects were given foods that either had a high glycemic load or a low glycemic load.

For the next 6 months, subjects provided their own food.

 

Weight Loss

Weight loss the same: 7.8% vs 8%

After a year, the weight loss of both groups was the same.

Those in the low glycemic group had lost an average of 7.8 percent of their body weight, while those in the high glycemic group had lost an average of 8.0 percent of their body weight.

 

Conclusion

Conclusion: Glycemic load does not affect weight loss

The paper concluded that “diets differing substantially in glycemic load induce comparable long-term weight loss.”
