I wouldn’t just assume you’re doomed. I don’t necessarily feel doomed. Weight isn’t so important to me as physically feeling good is. I mean, at 100 lbs before an unexpected thrust into menopause I’d probably only feel good about losing half the weight I gained. It has it’s advantages too, I have boobs now. I never really had those as a stick figure.
In my experience I’ve done much better listening to my body than listening to my friends.
