Just don't raid the pantry like i used too. You've just had a bub, so the weight will fall off don't you worry. the cold weather doesn't really get me motivated either to do some kind of exercise.
I can't lose weight easily either, i've got PCOS, so my fat cells are very stubborn and the insulin resistance which comes with PCOS doesn't help either as i always crave sugary foods. I find the sugar free lollies are good for that though.
