What the others have said about being committing to changing your life is right, but since surgery, it has been so much easier for me to make that committment than before surgery. It feels like I just don't have the physical or mental desire to eat the unhealthy stuff that I used to fight every minute of every day. My surgeon explained that it was the removal during surgery of the part of the stomach that produces grehlin, the appetite stimulant. hormone. I'm 4 years out and originally lost 70 pounds. I've gained and lost 10 pounds of that a couple of times in that 4 years, but it's so much easier to lose than before surgery, and so much harder to gain. And I'm positive that without surgery, I might have been able to lose 70 pounds, but I'd have gained back 100. Yes, working out will help. Before surgery, I never wanted to, but now it comes a lot easier too.
