Forty-five overweight patients (12 male, 33 female) were prescribed a very-low-calorie diet (VLCD) or a supplemental low-calorie diet (LCD), randomly, at an outpatient clinic. Twenty obese patients [31.6 +/- 13.1 y; body mass index (BMI) 32.9 +/- 6.1] were treated with a VLCD of 1757 kJ/d for 1-2 mo (five packages of Optifast 70/d; Sandoz Nutrition, Minneapolis). Another 25 patients (35.3 +/- 11.7 y; BMI 31.9 +/- 4.4) were treated by a supplemental LCD of 3515-5021 kJ/d for 1-2 months, which consisted of two to three packages of Optifast 70 and 2678-3682 kJ of conventional balanced meals. By the fourth week, the weight reduction obtained by the VLCD was significantly greater than that achieved by the supplemental LCD (P less than 0.01). At the eighth week, however, effect of the VLCD and the supplemental LCD in terms of weight reduction did not differ significantly. No serious side effects were observed in either treatment group. However, remarkable elevation of serum uric acid concentration was detected in seven patients on the VLCD. The treatment period of the VLCD is limited to less than or equal to 3 mo. On the other hand, obese patients can be treated with the supplemental LCD for greater than 3 mo. Therefore, the supplemental LCD is considered to be useful in the treatment of moderately obese Japanese patients on an outpatient basis.
