Stopping Reta

Has anyone successfully used Reta to lean out, then completely stopped taking it and kept the weight off? Part of the function of Reta is appetite suppression, but there is also another part that affects insulin sensitivity/metabolism, I’m wondering if keeping the diet discipline that that appetite suppression gives after stopping is enough to keep the weight off or does removing the metabolic signaling cause your body to revert back to how it was before taking it
