TORONTO — Overweight teens assigned to a 6-month low-carbohydrate diet experienced significant weight loss, decreased body mass index, and improved self-esteem while being managed in an office-based setting, Dr. Robert Siegel reported at the annual meeting of the Pediatric Academic Societies.
“The question we asked is can a low-carbohydrate diet be practically implemented in the office setting,” said Dr. Siegel of Cincinnati Children's Hospital. Dr. Siegel also is the medical director of the Cincinnati Pediatric Research Group (CPRG), a network of 47 practice-based pediatricians in the Cincinnati area committed to translating research into practice.
Interestingly enough, fat intake by self-report did not significantly increase in these subjects. Increased fat intake is a concern with low-carbohydrate diets, he said.
A total of 63 healthy children 12–18 years of age and with a body mass index (BMI) greater than the 95th percentile for age were put on a low-carb diet (LCD) of less than 50 g of carbohydrate daily. Subjects were seen regularly by a dietitian and counseled on good nutrition and physical activity along with specific LCD recommendations.
A total of 38 teens (60%) finished the 6-month study. The mean age of the study group was 15 years; 79% were female. Twenty-two percent were African American, 74% were white, and the ethnicity of the rest was unspecified.
Overall caloric intake and carbohydrate intake both dropped significantly during the 6-month study period. At baseline, average carbohydrate intake was 324 g daily and dropped precipitously to 62 g/day at 6 months.
Fat and protein intake did not, however, differ significantly between baseline and 6 months.
Average body weight dropped from 93.4 kg to 88.3 kg, BMI fell from 34.9 to 32.5, and BMI percentile fell from 98.4 to 97.1.
A total of 32 of 38 teens lost at least some weight during the study period; the greatest loss was 23.9 kg of body weight. Average weight loss was 5.1 kg.
There also was a significant improvement in Rosenberg Self Esteem Scale scores, from 16.6 at baseline to 15.0 at 6 months. At study end, 54% of teens felt that the LCD was easier to follow than previously tried diets, and 38% said they planned to remain on the diet beyond 1 year.
“We tried to in our study mirror what goes on in practices,” said Dr. Siegel. However, not all practices have access to a dietitian, and the study wasn't randomized.
This study was funded by the Dr. Robert C. and Veronica Atkins Foundation.
