Newsround is investigating the problem of obesity in kids.
If you're interested in taking part in a special programme about this, then we want to hear from you.
You might be overweight yourself and suffered bullying because of your weight, or you might just have a view on the problem of obesity.
Who's fault do you think it is? How do you think it can be solved?
Let us know.
Thanks for your comment. We're only asking for your telephone number in case you'd like us to contact you. You don't have to include it and we promise we won't pass it on to anyone else or keep it on file.
