we had the same problem. My son ate alot in the morning and evening, hardly anything for lunch. I pretty much stopped worrying about nutritious and did what I could just to get calories in him. He developed a liking for peanut butter and chocolate chip sandwiches. Also chocolate chip pancakes in the morning. Do you see a pattern?
good idea about the instant breakfast, my son won't drink any kind of milk concoction. Trail mix is a great idea.
I tried to have lots of things on hand that he could just make for himself when he got hungry (like cans of ravioli). I also decided to not worry about meal times and make battles out of that--if he didn't want to eat there was no point making a huge deal about getting him to eat.
Are you at the lowest level of the patch? Just thinking that if it is to primarily help at school, could you go to a slightly lower level on weekends and see if that helps his appetite?
You may also find that the appetite loss might moderate after a while --maybe the body will get more used to it.
