HI All, Reaching out here because it would seem I cant find any support and I thought here might help. I quit smoking in 2013 and truly have never looked back. I have lost 127 in 2003 and kept it off until I quit. I did gain 10 lbs after i quit but not from food. Apparently my metabolism along with my thyroid died at the same time. I guess nicotine really was a preservative. Anyway, I workout 6 days a week for 45-50 minutes, I am on WW so eating is not the issue but no matter what I do I cant lose weight and now it is more like 40 lbs as anything remotely like a carb and I gain. My thyroid medication is regulated now after almost 2 years and my doctor tell me all hormones and stress levels are normal so my only thought it that my metabolism is still a wack. Anyone else experience this lack of ability to lose weight no matter how much diet and exercise? Any thoughts are helpful.
