Values at baseline, 4 weeks and 8 weeks are listed as means ± standard deviation. Mean changes (Δ) ± standard deviation after 4 weeks and 8 weeks compared to baseline are listed in the last two columns. A negative value indicates a decrease in value and a positive number represents an increase in value. Values* are significant comparisons (<0.05) based on analysis of variance model results comparing changes from baseline to 4 weeks or 8 weeks. Groups are as follows: OP = overweight/placebo, OT = overweight/treatment, NP = normal weight/placebo and NT = normal weight/treatment.
