WOW! great topic.
I am 5'5' and I weigh between 127-135, I don't like flucuating and I feel better when I stick at 127, which is hard for me since my metabolism is slow, so I really have to watch what I eat, which I find really really annoying.
However... I used to be 175 pounds, so I went through a big weight loss about 5 years ago. So my weight is fairly important to me just because I feel more healthy now and my body image has improved immensely. I work out every day, excercise is really important to my well-being now.
I think it just plain sucks that we as a society put so much pressure on women to be thin and to literally... "take up less space." I find it appalling when I feel good about my friends saying I shouldn't lose more weight, that I am looking 'frail.' I think what we promote as a society is awful message to send to women and girls. Smaller is Not better... I like what others have said on here, that being 'healthy' is important and that Feeling healthy is better than feeling 'thin'
I really love this website, it has some really great article and personal stories about women who have overcome judging themselves by the scale and accepted their bodies as beautiful just the way they are. check it out.
