A carefully controlled animal study provides clear evidence that a low-glycemic-index (low-GI) diet -- one whose carbohydrates are low in sugar or release sugar slowly -- can lead to weight loss, reduced body fat and reduction in risk factors for diabetes and cardiovascular disease.
"The study findings should give impetus to large-scale trials of low-GI diets in humans," said senior author David Ludwig, MD, PhD, director of the Optimal Weight for Life (OWL) obesity program at Children's Hospital Boston. His group's findings appear in the Lancet.
