Most of the people on GLP will come off the drugs and regain the weight back to their original weight, if not heavier, just like people who temporarily restrict eating in any other way (discipline). You need real lifestyle change. Even the people shilling the drugs tell people that.
Personally, I hope all of these business fail. Screw the fast food industry, dieting companies (they don't want customers to actually succeed), and the pharma companies that are restricting access to people who actually need GLP drugs.
