Weight is something that effects 99% of the people around the world. It is funny how it is viewed in one culture, can be the complete opposite in another. I know that in places in Europe women with "a few extra pounds" are held in very high regard.
I believe a lot does have to do with self confidence. I have always had "a few extra pounds," but once I approached 200# I thought something has to change. I am 5'10", so it doesn't show as bad, but it's still there. I want to do something about it, but part of me is comfortable with how I look. My bf is a big part of it. He loves me no matter my size. He always tells me how sexy and beautiful I look. Since we started dating, we both put some weight on, and I think it's because we are so in love, it doesn't matter our size. Point is, you have to have confidence in yourself. When we first got together, I didn't have a lot of it. After a few months, I felt so good about myself. I am convinced this is why, at this point, a diet doesn't exactly work. I don't want it enough, b/c a part of me is happy with how I look. Women, you need to look inside, and love you. Be proud of how you look, no matter your size. If you have confidence, your life will change drastically. You might not lose weight, but you will be happier. Also, for those like me who want to lose weight, don't try a diet until you are 100% sure you want this. If even a part of you isn't sure, it's not time yet.
Just my two cents. Just be proud of who you are. I guess this goes for men and women. I know men have issues with weight as well (my bf included).
