Can you tell me the name of the facebook group? For me, I started at 285, (100 cm CC) went to 132 (skeletal) and was told to gain 5-10 pounds. Got to 150 and stayed more or less there for 8 years. Then, lost 10 pounds without trying at year 8. Stuck there for the last 2 years. I discount the BMI for the formerly obese, since we have excess skin and heavier bones. I have a normal BMI, but my surgeon told me to stop losing weight. I don't know that surgical comparisons explain differences in results, since we differ in terms of metabolism, diet, endocrine status, exercise, lifestyle, age, previous abdominal surgery, and other medical conditions, not just the surgeon's choices. Ultimately, the DS scorecard can't be only about weight, it's also and more importantly about health and quality of life.
