title: A pilot Internet-based behavioral weight loss intervention with or without commercially available portion-controlled foods.
abstract: OBJECTIVE
  To evaluate the short-term impact of portion-controlled food provision in combination with an Internet behavioral weight loss program on weight, blood cholesterol, and blood glucose levels.
  
  
  METHODS
  Fifty participants, mean age 46 ± 10.7 years and mean body mass index 35.1 ± 3.8 kg/m2 , were randomized to one of two study groups, an Internet behavioral weight loss program (Internet-alone; n = 25) or an Internet behavioral weight loss program plus a commercially available portion-controlled diet (Internet + PCD; n = 25) for 12 weeks.
  
  
  RESULTS
  An intent-to-treat analysis found that the mean weight change in the Internet + PCD group was -5.7 ± 5.6 kg and in the Internet-alone group (n = 25) was -4.1 ± 4.0 kg (P = 0.26). Participants in the Internet + PCD group achieved significantly greater improvements in blood glucose (-2.6 ± 5.7 vs. 1.4 ± 11.0 mg/dl; P = 0.05) and LDL cholesterol (-8.2 ± 18.0 vs. -0.6 ± 21.0 mg/dl; P = 0.04), compared with Internet-alone group.
  
  
  CONCLUSIONS
  These data suggest that there may be short-term clinical benefit in using a PCD in conjunction with a behavioral Internet-based weight loss program to enhance weight loss and improve health indicators.
