I actually have no problems with food/snacks acting as treats, but the key is to use moderation. I love zoyo, I don't eat there hardly ever, but there are times when the day just went perfect and I feel like some soft serve. The main difference between me and fatties though is I get a human sized portion instead of filling the largest cup as full as possible (actually seen this, it was gross).  There is nothing wrong with treats being food, but there is something wrong with eating everything left in have house and calling it a "treat."
