That doctor pissed me off. He knows better yet he's lying. He compared carbs for fucking heroin.  "If we know diet and exercise doesn't work this is the only thing that will" BULLSHIT. Proper Diet and exercise always work. The failure is always on the person or execution. You cannot get more energy from a system than you put into it. CICO will get your weight down. These people are such failures they need to literally staple their stomach in half to prevent themselves from shoveling food into their gullet.
