A comma would have made that sentence much better, my apologies. The clinical data on long-term weight loss is miserable. The fact is that almost everyone gains weight back (as high as 95% of patients after 5 years), and something like 60% gain more weight back than they started.
I went on to speculate that most people who are obese have an underlying condition.
