Baseline EQ-5D was 0. Participants were excluded if exercise or dietary fat reduction was contraindicated for medical reasons, if they had active cancer or type 1 diabetes, or if they reported symptoms of an eating disorder or depression.

Unlike in a linear regression, where the sample size depends on the ratio of subjects to variables, in a path analysis it depends on the number of parameters to be estimated. The multidisciplinary program, delivered to groups of 11—15 participants, focused on changing lifestyle rather than weight loss per se. Weight loss in 2 wks increases the risk for many chronic conditions including type 2 diabetes and cardiovascular disease and negatively impacts quality-of-life.

Therefore, we conducted a study to investigate the immediate post-intervention 6 months and long-term 12 and 24 months effects of clinically based weight management programs on HRQL.

To the extent that an obese individual underestimates the impact of his pre-intervention weight on HRQL, and to the extent that his HRQL after weight loss is better than predicted by his reduced BMI, cost-utility analyses will underestimate the value of obesity treatments.

Furthermore, the presence of binge-eating disorder was not evaluated, which could have affected the results.

We also constructed scatter plots using solid circles for baseline data and open squares for follow-up data with HRQL on the y-axis and BMI on the x-axis. Over the first 12 to 16 weeks of the program, patients were also asked to gradually increase their physical activity low to moderate intensity to 40 minutes per day.
