You say you "don't want to eat more" that right there is one reason it will be hard to reach your goals. If you don't want to do it yourself why would others help? Its not hard to eat more, at first yes. You need to stretch your stomach out and get used to eating larger quantities, you will be uncomfortable at times but soon you will get used to it. I was going through the same thing once. In order to get a large amount of calories without having to eat a lot of solid food I would make these monster calorie shakes. I would use calorie rich ingredients like ice cream, peanut butter, protein powder, olive oil, whole milk, whatever I could come up with.
You might try that in order to put on weight.
