Why did patients apply to this trial?

I have been trying to lose the required 5-10% of my body weight, but with insulin resistance and Metabolic Syndrome I am having a very difficult time. I have noted recent changes in how my body looks and find it very distressing. This trial would be an excellent opportunity to see if an experimental med might work.
PatientReceived 2+ prior treatments
I've been trying for 20+ years to lose weight...fad diets, exercise, lifestyle changes, doctors, weight loss programs, pills, etc. Some methods worked better than others but I have never come close to achieving my goal weight. While I have been able to lose over 100lbs over a 4 year period, I am still struggling, and am, in fact, gaining again. The excess weight is affecting my daily life like it never has before and I need help.
