On Nov. 24 this year, Dr. Pereira published the conclusions of his study in Journal of The American Medical Association.

The study was made on 39 obese adults, ages 18 to 40.

Half of Pereira's subjects were assigned to a low-fat diet, the other half to a low-glycemic one. The low-glycemic dietary program was based on low-glycemic foods and moderate fat consumption, a scheme that closely resembles the popular Zone Diet . The calorie-intakes looked as following:

Pereira and his team measured some key-factors known as type II diabetes & heart disease predictors: blood pressure, blood fats, insulin resistance. Also, the resting metabolic rate (RMR) and total weight loss were measured on both groups.

The low-glycemic diet group showed twice better figures than the low-fat diet one. The differences in average weight loss were irrelevant. People on both groups dropped around 10% of body fat during the study.

The major criticism that Dr. Barry Sears had to confront with along the years was the lack of medical proof that Zone Diet does work. In his books he makes claims that are as close to a medical miracle as one can get.

The late Pereira study comes right in time to fill the need. A recent statement from an American Heart Association official, professor Alice Lichtenstein, admits that the results of the Pereira study can not be conferred to low-glycemic foods alone, or to moderate-fat foods alone. It could be the combination that worked.
