Again, it is about being fine with yourself. If you don’t feel good about it, then you should change it, physically or mentally.
I never said you are not meant to care about a gain or how you feel. I said that if someone would be completely fine with herself. Only then realises she had gained a couple of pounds when she stands on a scale and the number has changed, ruining her whole self esteem and mood... that to me is twisted. But only if that person was completely fine with herself just before stepping on the scale. For who is not feeling fine, feels like she has become heavier against her own liking, so who is not comfortable with herself. That is a whole different story! Than yes, you should do something about it if it would make you feel better. And I would fully support that, as I said in my previous post.
