Welcome! I did almost the same thing two years ago. Started, stopped, and went right back because it was obvious at that point that I had to. Was stuck at 190 (from 215, just cutting soda and candy, still living on spaghetti)) and flabby, now I'm in the 170-175 range and adding muscle all the time! Give it time, too. 21 days might be a great start, but some people gain health more slowly than others.
Don't fear the bacon!
