An 800-pound Rhode Island man says he was kicked out of a weight loss program for ordering pizza.  Steven Assanti said he is addicted to food and was enrolled in a program at Rhode Island Hospital for 80 days.  He had already lost more than 20 pounds when he decided to order a pizza earlier this week.  He was asked to leave shortly after for breaking the rules and is now homeless.  The hospital hasn't commented on the issue.
