Rather than the specific weight, I think that it is more important to figure what changes in lifestyle you are willing to make permanently. This is why people's weight goes up in down. They reach their goal and then slowly begin doing what they used to do. For me, the best way to keep my weight from going back up--I have to exercise daily. Most of my life I have done this. If I stop for six months and am not overeating--I do not immediately gain it back but if I am not in shape (I think exercise helps boost metabolism) then when I am not busy or the holidays come--that sort of thing--then my weight comes back. Despite the cake I had this morning--I try not to keep too many sweets, bread, cookies, etc. in the house. I no longer have alcohol in the house. I mostly cook low carb, low glycemic index meals....
