Sounds like my story
especially the slowish weight loss. I always have that trouble! Or sometimes I'll lose a few kilos and then stall for no reason. Frustrating!
I've also lost weight twice and then put it back on. I know what you mean about accountability; I always did better when someone was checking up on me, so that's what I'm doing here, too.
I quite like CalorieKing.com.au. They have a food diary there that you can fill in from their database or add your own stuff. Does all the math for you
I'm going to start the "university" course (lol) today, since it's all free.
It seems like there are a million sites offering help and advice with weight loss, but so far I have found this one really good. I'm not losing weight yet (until our first bub is born in May) but I've been lurking and reading... everyone in the forum seems so friendly and supportive. Hope you feel welcome here and that the support helps you in your efforts, too!
