Repeated use of the very-low-calorie diet in a structured multidisciplinary weight-management program.

Forty-eight obese patients (mean body mass index = 36.4) were retreated with a very-low-calorie diet (VLCD) at a mean of 104-wk after first VLCD. Mean weight regain was 23 kg or 86% regain of initial loss. Retreatment with VLCD required weekly physician monitoring and indepth psychotherapy group attendance. Five patients (10%) lost an average of 4.55 kg and withdrew within the first 4 wk (group AO. Thirteen patients (27%) lost 13.8 kg over 11.5 wk, an average weight loss of 1.2 kg/wk and enrolled in maintenance (group B). Thirty patients (63%) lost 10.2 kg over 20 wk, an average weight loss of 0.5 kg/wk and did not enroll in the maintenance program (group C). Although weight loss occurs in patients retreated with the VLCD, adherence to the VLCD and commitment to the maintenance program are not optimal.
