Or you can just live on a hill like us

There's a hike between me and the shops any anything I buy I have to carry home.
I counted 140 steps between my son's play group and home too - Tuesdays I do that twice before lunch carrying a 5 kg baby plus usually some shopping on the way back up. I certainly don't need a gym.
For loosing weight, I was in hospital during pregnancy on bed rest. 3 big meals a day - so I thought that i'd put on loads of weight. After 10 days I was lighter. The main difference to what I was eating at home was that there was no bread after breakfast. Snacks were fruits or yogurt and I couldn't get my hands on sweets. There's also seems to be some truth in the saying "skinny people don't skip breakfast". If I skip breakfast I end up eating some high calory convenience snack from the bakery and then need to eat more for lunch.
