knowing to STOP and come back here is a good step! I agree, do whatever it was that worked for you before, and make a plan on how to maintain and keep going. I posted a thread about re-gaining not too long ago and almost everyone says the best way to avoid it is to NOT BE ON A DIET right?? if you're ON a diet, you go OFF a diet. If it's just life, it is what it is
My favourite tip a friend gave me: EAT DINNER WEARING SUPER TIGHT PANTS hahahah weird but it worked for me back then. I could barely do them up and it was so uncomfortable i didn't eat much and was super motivated to stick with it LOL
