Wait, weight?

I went to see the dietitian today after waiting for what seems like forever! Anyway, she told me that I need to eat more in order to gain weight, a mix of protein and calories, which I can get from the 5 food groups, by eating 6 meals a day. Yes, 6. She said I need to aim for 3000 calories per day. That is the equivalent of eating 6 McDonald's Crispy Chicken Deluxe sandwiches or 28 kit kats a day!
There was also some good yet bad news. I have grown an extra inch and a half, so now my 'ideal' weight is half a stone more than what I was aiming for! *headdesk*
