I think that for some people (I'm guessing
*@managedmis* and I'd include myself) they feel that it is a choice between being slim (size 8/10) and being massively overweight and risking the health problems that being obese brings. Before you bite, let me explain:
If I am a size 10, I have to work at it to stay there. But at that size, I am light enough to exercise, and do it well. Because of my ultra-competitive nature, I hate doing something I'm crap at, so if I run 5k when I'm a size 14, I'm slow, it hurts my knees, and I don't enjoy it, so I feel rubbish, whereas if I'm a size 10, it hurts less and I go faster, so I enjoy it more.
Also, if I'm a size 14, I feel fat and horrible, so it starts affecting my mental health. So I eat more, put on more weight and suddenly I'll find I'm a size 18 and obese.
So for some people, who have a complicated relationship with food or their weight, it does feel like a binary choice between being a size 8/10 and being a size 18/20.
I'm not saying that's right, and I fully recognise that it's not a great state of mind to be in, and I sincerely wish it was a simple as saying "don't obsess about your weight" and "don't connect your happiness with your size" but that's just like saying "don't be depressed" to someone with depression, or "don't have a broken leg" to someone with a broken leg. I'm working on it though, so if anyone has any tips on how to break the connection, please please tell me.
