"I'm taking it week by week so I don't get frustrated with myself," she said at the time. "If I had a long-term goal, and that's all I thought about it, I think it would set me back more. So I really, every week, try to make sure I stick with my points and get four workouts in. That's my goal this week, and I hope that I can lose from that. If not, I'm going to keep on going and try it the next week. So far, so good."
