Need Help Please! Diabetic Mass Diet

I am posting this for a buddy who has just started training with me; he is a diabetic and is underweight for his height and age. He eats like a horse but continues to lose weight. His doctor has told him that because of the sugar levels he will not put on any weight till his diet is corrected. He is unable to pay to see detritions which I am really pushing for.

He is not to the point where he is on insulin, but does take pills daily. He is 31 years old about 6'-6'1 and around 150 pounds. Can anyone help me point him in the direction of a good mass/weight gaining diet suited for diabetics as he can not eat allot of the same foods we do to gain? This would be greatly appreciated by both myself and my friend.
