Patients do indeed need the drug to keep the weight off. They have proven this. But that is not an issue at all. Individuals who have gained a significant amount of weight do not produce leptin, grehlin, and other related hormones in the same way that people at a normal weight do. Once you’ve put on a significant amount of weight you can’t just expand the size of your fat cells you make new cells entirely. Even if you remove those new cells via liposuction, the body recreates them as a homeostatic response. The result is that something like 10% of obese people that lose weight have kept it off two years later. The people who keep it off have been studied extensively as a group and generally they weigh themselves daily and many of them count calories meticulously. As soon as they stop doing that, they regain the weight. It’s a path dependent outcome. Once you’ve walked the path to obesity, your body fights you walking back towards healthy. This drug adjusts some of the same hormones that get out of whack when you’ve been overweight before. Unfortunately not all of them can be safely played with (giving people leptin and leptin like hormones tends to cause cancer for example). But these seem to be both safe and effective. There really shouldn’t be a stigma associated with taking drugs like these for the rest of your life. |

That's a good point I hadn't considered. Thanks!
