Picky would be an understatement for me.
Let's see, ice cream, I would only eat Hagen Daas, Ben & Jerry's, Coldstone, ot Andy's --- cheesecake, my wife makes the Best, cheesecake factory was a sacrifice for me--- pies, well I really didn't do any fruit pies but a good peach cobbler never survived long around me--- this only lists a few of the "treats" I'd eat.
Let's keep it real though. You need to be ready for a lifestyle change. Yes, as time progresses you'll be able to eat small portions of anything. But to start you will be very limited and will need to Mae some sacrifices to get the best results.
