When severe, obesity in adolescence demands effective treatment, thus justifying use of a protein-sparing, low-energy diet for periods of 3 to 4 months. When properly planned and supervised, this diet is safe and effective, even if only to maintain a functional body weight. The regimen used at the Hospital for Sick Children, Toronto, provides 2.0 to 2.5 gm protein per kilogram ideal body weight, plus adequate fluid and nutrient supplements. The amounts of meat, poultry, and fish that supply this allocation of protein are determined using a protein equivalency system developed for the diet. The system allows both dietitians and patients to plan meals that minimize energy intake while maintaining protein adequacy and dietary variety. With prolonged use of the diet, limited carbohydrate may be added in the form of selected vegetables measured using a similar carbohydrate equivalency system. Recent use of the diet for 21 patients, 8 to 20 1/2 years old and averaging 211% ideal body weight, resulted in acceptable weight control.
青春期严重肥胖时需要有效治疗，因此有理由在3至4个月的时间内采用低能量、蛋白质节省型饮食。如果规划和监督得当，这种饮食即使只是为了维持正常体重也是安全有效的。多伦多病童医院采用的饮食方案为每千克理想体重提供2.0至2.5克蛋白质，外加充足的液体和营养补充剂。供应这一蛋白质分配量所需的肉类、家禽和鱼类数量，是使用为该饮食方案开发的蛋白质当量系统来确定的。该系统使营养师和患者都能规划出既能减少能量摄入又能维持蛋白质充足和饮食多样性的膳食。长期采用该饮食方案时，可采用类似的碳水化合物当量系统，以选定蔬菜的形式添加有限的碳水化合物。最近对21名年龄在8至20.5岁、平均体重为理想体重211%的患者采用该饮食方案，体重控制效果良好。
