I watch the show mainly to see Amy's progress. It used to be both of them but Tammy has got to the point that she's not even trying anymore. She either has an excuse, blames someone else or just clams up. If she would take 10 steps a day for a couple days, then add steps to it, she would be able to at least walk to the mailbox. If she doesn't get her way and what she wants, she makes it hell for everyone else. Last episode, on the vacation......she wanted to be alone yet when the call her to go eat, there she goes. She's motivated by food, not her health.
