Lowest maintainable weight????

Looking at my ticker I would LOVE to lose about another 20 lbs. Everyone SWEARS I don't have another 20 to lose. But that would put me at 130 lbs...yes I weighed that when I was 21.

Now I'm 50 years old. Yes...I could  STILL step up my exercise. But...I'm seriously wondering...can 150 lbs be my lowest maintainable weight??? Now I'm not complaining...I'm comfortably wearing a small top and 8-10 in pants. But am I KILLING myself over losing 20 more lbs thats not possible to get off and more importantly keep off???? Any thoughts out there????

It pretty much depends on how hard you want to work the rest of your life to control your food and exercise needed to maintain that weight.   Look real close at - will it ever be enough   am I avoiding maintenace because I've never been able to do it before?  But if you want it, you're willing to do whatever it takes to lose/maintain it - then GO FOR IT   After all, if you lose it and you decide you don't like how you look or it isn't worth the effort - I guarantee you you will not have developed amnesia - you will know how to gain some back  LOL

I have kinda adjusted my goal. Since I was heavy since age 4 and the smallest at age 18 in my adult life when I dieted my way to 160. (Was 230 in highschool and got up to 330 at heaviest). Looking at my genetics, Mom was lowest at 140. We are only 5 ft 2 so still overweight but I have set my goal at 145. I am 42 years old and would love to weigh 105 or something but not gonna drive myself crazy getting there. 145 is enough of a struggle. Got within  6 pounds of it after surgery and then re-gained. So in my opinion, if you are healthy quit struggling or you could meet in middle and say 140. Isn't it time we had peace with ourselves?
