There still is plenty of restriction, but eating high calorie foods, even just small portions soon adds up and you need to stick to excerising if you are going to stay toned.
I eat no where near as much as I did before the op, but you still have to be careful, but its very manageable with the sleeve which makes all the difference.
I would say that a year out, I am just like every other women...I have to watch what I eat to keep my weight under control and I need to exercise to stay toned. But its more about maintaining. I would have never lost over 6 stone without my sleeve.
Best of luck for May, you won't regret it.
