I'm also amazed that the first comments that someone gets when they ask for advice on a child being teased are 'well, are the bullies right?'
So what if they are? They still shouldn't be teasing her about it.
If she wore glasses, would people advice contacts or laser surgery so that she wouldn't need them?
It's not up to anyone else to judge whether the child should lose weight or not - it's still not an acceptable reason for teasing. But it's just so prevalent in society to see fat as this horrible moral issue, that people are automatically judgemental - for no other issue would people ask first if it was true, as if that were some justification for the comments.
yes, it's a health risk to be obese. I'm sure people don't generally need that pointing out. Many overweight people are not obese. It's not a moral issue, it doesn't make them bad people or lazy or weak-willed or anything else. And it certainly shouldn't be an excuse for allowing teasing or comments by other children/adults.
I was a fat child. Not obese, but a little on the heavy side. Not to the point it was likely to be a health risk. This was despite attempts to make me exercise more. I ate a fairly healthy diet at most meals. I wanted more of all the carbs etc right from the beginning and it's harder to control portion sizes as a child gets older, or has any access to food on their own. I hated exercise, just never found anything I enjoyed despite lots of attempts - I did swimming lessons, I rode my bike, I walked to school, we did family hikes. But I wasn't a running around sort of child - I preferred to read. So I exercised when I had to. It wasn't really my parents' fault - my sisters were both slim. So I was on the fatter side, and I also grew quite early as I was old for my year. I look at photos now and think I was slightly plump but by no means dangerously large - and yet I hated myself, everything about myself, to a large part because of the comments about looks and shape. My weight wasn't particularly unhealthy, and far, far more damage has been done to my health and self esteem by the endless diets, back and forth yo-yoing, eating disorders, bullying, anxiety, shame, etc that resulted from comments, leading to problems as an adult with my weight, health and self-image.
