Ok — one more answer after reading part 2 first.
Since 5 years ago I have been underweight most of my life and enjoyed it. I am now in a normal weight range and feel like a whale which I am nowhere near of course. The belly is also my biggest problem and I haven’t even ever been pregnant.
Well I am 47 (soon) and have to look like a hungry child anymore, so I try my best to embrace it how it is.
