How can you best people with eating disorders

Eating disorders like obesity can be treated with the usage of dieting (if time allows) or surgeries. “Non-eating” disorders are usually the result of mental unrest, so these are usually treated by psychologists and psychiatrists.

Talk to them, if it's early it'll be easier to help them. It's not something they can control though it's in the mind. Tell an adult and if they are an adult talk to their family and talk to the person about getting help. Make sure they know you are there for them and that they are perfect the way they are. You can't change how they see themselves though, they need therapy to help them. 

I hope this helps : )
