Thank you, that does help. He's a full-time student right now and his only form of exercise is walking around campus or walking at the store with me so he'll have to be careful with his carbs. Starchy veggies would be another alternative but I doubt I can talk him into grains--when he stopped eating grains, all of his stomach ailments magically disappeared. We can't even walk through the bread aisle without him feeling nauseous now because he's so turned off by even the smell of grains. He says that he smells that and associates it with feeling sick. So fruits and starchy veggies it is then!
Thanks for the tips!
