While not this obese, I have gone through a similar experience in the last couple of years where medication almost completely suppressed my hunger trigger. As a result I kind of "accidentally" did intermittent fasting for over a year. My BMI went from 31 to 24 in the span of half a year, at which point my colleagues were getting worried because of the rapid weight loss and I started to rationally force myself to eat during lunchtime. Since a couple of months the hunger suppression is no longer an issue, but it has been surprisingly easy to maintain a healthy weight and healthy eating habits since. I suspect one part of the problem is that the body takes a long time to adjust to what it considers a new "normal" weight, which is why diets often don't work. Maybe if they were specifically oriented towards staying at a certain weight for an extended period of time?
