I think the 140s are gated for me. I'll hit 150 SO many times and get stuck... then gain...
Personal barriers. I guess just keep at it, maybe change the routine a smidge like add running or maybe try upping the calories 100-200 a day for a bit or dropping them 100-200 a day for a bit (just don't go below 1200cal). Sometimes a small change shocks our body into dropping a little more.
Either way, STICK WITH IT! Don't be like me and quit because the drops stopped. If I had stuck with it, I would either be at my goal, or at least I'd be 150 instead of 23lbs heavier.
I've decided to leave 3FC, In the crowd of so many, those of us with no success that have the audacity to feel bad about our incredibly slow and almost stagnate weight loss, are merely a nuisance to those that are successful. I hope everyone else finds the support they need.
