I must say you have a good and beautiful friend… Nowadays its difficult to find such people around you who are not ashamed of what they are. And the one like your friend is truly inspiring. Such friends often teaches us many things… Like eveybody should love their flaws instead of hating them.  Then I guess life would be more simple and beautiful. 
Everyone around you would also love you for your acceptance towards world harsh things. Like you praising your friend.

Yes, a friend like this can actually inspire anyone they interact. Body shaming is nothing but just a reason to worry and keep worrying. Things cannot work like this. Your friend has done a great job. Start accepting as you are and know your worth. Physical appearance can’t define us. Be confident about how you look. Be positive about yourself and appearance. Keep inspiring others:)
