Body Mass Index The Primary outcome will be a change in body mass index (BMI). Preliminary statistical analysis reveals that to show a statistically significant decrease in BMI of 1.25 points, given the large effect size, requires a sample size of 24 subjects, 12 in each group, to achieve 80% power with an alpha of 0.05. Our sample size of 40 is adequate to determine if there is a significant improvement in BMI. BMI will be measured and recorded at each study visit.
