How do i help my fat friend?!

news flash, you are still tormenting him and alienating him, then you are not really his friend. If you really want to help him apologize for tormenting him, let go of your issues with his weight and be nice to him. middle school is hard enough for kids with self image without people like you treating him like crap.

Sit with him at lunch and hang out with him as much as you can, especially if you eat a snack during that time. When you eat, put some healthy things in your lunch like celery or carrots. Offer some to him. If you're eating the healthy stuff he eats, then it won't feel like so much of a burden to him to eat healthy. Good luck!

That wasnt very nice of you to make fun of him.Tell him your sorry, and take him to the gym. Or ask him to go for a walk. Dont make fun of him anymore, if he chooses not to excersise and stay overweight, thats his problem not yourrs.

Don't you help him and how do you call yourself his friend? Leave the poor kid alone, let him do the choices.

His body. Worry bout ur own. Unless ur interested in men, why don't u care about women? Like men, eh?

is his name Connor Noe?

I desperately hope you're a troll.

If this is for real...
You're not a doctor. You might be concerned about his health, but it's not your place to do anything. Weight is a very sensitive issue, especially if you've already bullied him for it.
Even if he does lose weight because of what you've done, it wouldn't be for the right reasons. No one should ever have to change the way they look so they won't be bullied.
You need to apologize for making fun of him. You said you feel bad about it? Tell him! Don't let him see the world as cruel because of you.
Then, just leave him alone. Don't be super-super-nice to him, he'll think you just want to make fun of him behind his back. But smile at him every once in a while, and defiantly don't make fun of him for anything.
