Hi:...I too had these same questions...this is normal...everything we do daily revolves around food. I’ve spent hours reading and trying to understand why I could take the weight off, but couldn’t keep it off. I wasn’t heavy growing up, but put on a lot of weight after quitting smoking.
I think I finally started to understand why it’s so hard to keep weight off after reading “A Pound of Cure” by Matthew Weiner, MD, FACS, a Bariatric surgeon. He talks about your metabolic thermostat and resetting it. Spend some time collecting the facts. List all the pros and cons. I think this will help with your decision. I hope this helps.
