i have a the same problem and i do believe that it has ALOT to do with breastfeeding..
i have found that while im feeding i cant loose weight(i can stay the same not go lower)
i know when i stopped feeding ds i droped 10k very quickly.. DD doesnt look like giving up boob anytime soon.
this isnt for just "bad" foods i can eat and eat fruit and veg.. i over eat any type of food.

sorry i cant help.
