A low glycemic index diet does not cause greater weight loss than a high glycemic index diet according to a year-and-a-half study from Brazil. Weight Loss
Weight loss: 0.9 lbs vs 0.6 lbs
After the first two months, women in the low-glycemic index group had lost slightly more weight than those in the high-glycemic index group: 1.5 pounds versus 0.7 pounds.
After a year, both groups started regaining weight they had lost.
At the end of the year-and-a-half study, women in the low-glycemic index group had lost 0.9 pounds versus 0.6 pounds for those in the high-glycemic index group.
Glycemic index of the two diets: 40 vs 79
The glycemic index of the two diets was considerably different.
The low glycemic index diet had a glycemic index of 40 compared to 79 for the high glycemic index diet. This is a large difference.
Glycemic index is based on a scale of 0 to 100 with glucose being 100, so a difference of 40 to 79 is a large difference.
Subjects: 203 healthy women
The study involved 203 healthy women who were 25-45 years-old who were normal to overweight with a body mass index (BMI) of 23 to 30.
60% completed the study
Sixty percent of the women completed the study.
This is not unusual for any type of study lasting this long.
Conclusion: A low glycemic index diet does not cause greater weight loss
“Long-term weight changes were not significantly different between the [high-glycemic index] and [low-glycemic index] diet groups; therefore, this study does not support a benefit of an [low-glycemic index] diet for weight control,” concludes a new study from Brazil.
