No experience of units - but in order to put on weight safely, I would suggest a protein led diet ( to repair and add muscle ) with complex non sugar or refined carbohydrates. Perhaps a good quality protein shake ( 30g per scoop ), tuna and fish meals, chicken and turkey. Brown rice, quinoa and pulses. Cook with extra virgin olive oil. Vitamin sprays rather than pills ( Holland and Barratt ) Empty calories ( soda, mcDonalds etc ) will put on weight - but will decrease health so best to avoid those

Hope your daughter recovers x
