title: Effect of a post-dinner snack and partial meal replacement program on weight loss.
abstract: The objectives of this study were to examine whether providing a structured post-dinner snack would enhance weight loss among obese night snackers participating in a novel partial meal replacement (PMR) program and to examine the efficacy of that program. Sixty adults (age 18-65 years; body mass index >or=30 kg/m2), 29 randomized to the 'post-dinner snack' and 32 to the 'no snack' groups, completed the 8-week program. Both groups showed improvements in weight (-4.23 kg, P < 0.0001), body mass index (-1.48 kg/m2, P < 0.0001), body fat (-1.36%, P < 00.0001), waist circumference (-6.40 cm, P < 0.0001), and high-density lipoprotein-cholesterol (-2.72 mmol/l, P < 0.01), and on a night snacking question (-1.31, P < 0.0001). The 'post-dinner snack' group did not show significantly greater weight loss outcomes than the 'no snack' group either before or after taking compliance into consideration. Providing a structured post-dinner snack along with a PMR program did not enhance weight loss treatment outcomes; however, the PMR program produced beneficial weight loss changes for obese night snackers.
