Wow, 80 lbs! That's fantastic. Well, except for the misery.You lost 50? That's fantastic. I lost 80 about a year and a half ago. Keto also. Have kept it off, plus lost more after I stopped. A little cheating with that cdiff though. Got down 7 more lbs with misery.
I've been maintaining for a year without much effort. Still want to lose 15lbs more. Maybe I'll get up the gumption this winter. Keto is easier for me in cool weather.
