Percent change from baseline (a) body weight and (b) lean and fat mass by age group. Mean (±SD) for the Completers population grouped by age (<65 and ≥65 years). Completers included all individuals with weight data at the given visit; sample sizes are designated below the graph. Final Visit represents an individual’s last visit to the MWCC while on the 4 & 2 & 1 Plan. Significance levels for all within group changes from baseline were p < 0.0001 for body weight, p ≤ 0.002 for fat mass and p ≤ 0.05 for lean mass (not shown). Significance levels for between group comparisons using bivariate t-tests at each time point are shown: *p < 0.05; **p < 0.01; ***p < 0.0001
