Obese teens see results with high protein diet

Researchers report in The Journal of Pediatrics that they randomly assigned 24 severely obese teenagers to eat a high-protein, low-carbohydrate diet and 22 matched teens to eat a low-fat diet for 13 weeks. The study subjects were 14 years old on average and were at least 175 percent above ideal weight, but were free of type 2 diabetes or other serious medical problems. They were closely supervised throughout the study. On average, those on the high-protein, low-carb diet lost 29 pounds over 13 weeks, while those on the low-fat diet lost 16 pounds. Both groups kept the weight off nine months after the study. "We had expected the high-protein, low-carbohydrate group to quickly regain all the weight lost, but this did not occur," researchers said. "At the end of the day, this suggests that with ongoing support, these patients could perhaps have achieved even more weight loss."

The diet appeared to be safe, with no serious harmful effects on growth, bone mineral density, and various "metabolic" parameters, such as cholesterol levels. Both groups showed declines in levels of harmful LDL cholesterol and increases in levels of heart-healthy HDL cholesterol.
