Don't starve yourself. You shouldn't have hunger pain.
Because when you do eat a decent amount of food, you're body is gonna store it as fat for the next time you starve.
It's a survival mechanism.

Anyway, being overweight isn't the end of the world.
And if you want people to like you, then you have to start liking yourself.
If your generally positive about things, and smile, people will be more likely to want to be friends with you.
