Successful use of a ketogenic diet for weight loss in morbidly obese adolescents

      The ketogenic diet is a safe and effective method of weight reduction in morbidly obese adolescents who have not responded to standard dietary intervention. Seven adolescents, aged 12–15 years and weighing an average of 141 kgs (48.3 ± 9.1 BMI) safely lost 12.3–20.5 kgs (15.4 ± 2.8 kgs) while consuming a ketogenic diet (K Diet) for eight weeks. The K Diet was followed by 12 weeks of the baseline K Diet plus two carbohydrate sources per meal (K + 2 Diet). Within three days of the K + 2 Diet, subjects came out of ketosis but for 12 weeks did not regain any of the weight lost during the K Diet. Repeat body composition by DEXA (dual energy x-ray absorptiometry) and impedence indicated that the lost weight was all fat at 8 and 20 weeks of dietary intervention.
