Waianae Diet Program: long-term follow-up.

Abstract

A long-term follow-up was conducted on 82 participants from prior programs based on ad libitum feeding of a traditional Hawaiian diet. Follow-up period ranged from 12 months to 90 months and averaged 33.67 months. An average weight loss of 15.1 pounds was maintained over 7.5 years of follow-up (p < 0.0005) even when stratified over two year intervals, suggesting that this type of program may be an effective long-term weight loss intervention.
