简要总结
The study is to determine the effect of a behavioral weight loss program supplemented with Nutrisystem meal replacements on weight, blood pressure, fasting blood glucose, and blood lipids levels over 12 weeks.
详细描述
Specific Aim 1- Compare two programs, a standard Internet weight loss program and an Internet behavioral weight loss program, enhanced with Nutrisystem meal provision, on their effectiveness in producing weight loss and improvements in fasting blood glucose, blood pressure, and blood lipid levels over 12 weeks.
Specific Aim 2- Determine the usage and acceptability of the two programs.
Overall Hypothesis:
The Internet program with Nutrisystem meal provision will produce greater improvements in participant's health (weight, blood pressure, blood lipids, and fasting blood glucose) than the standard Internet program alone at 12 weeks. The acceptability and usage of each program will directly correlate with weight loss in participants.
Recruitment Methods Participants will be recruited through advertisements in local newspapers. Randomization A two-group randomized design will be used. After meeting all exclusion/inclusion criteria, completion of all study measurements, and provision of written consent, individuals will be randomized to one of the two study groups: (1) the standard Internet behavioral weight loss program alone or (2) the standard Internet program plus Nutrisystem meal provision.
