Jillian - May Family

Watch Jillian's show last night. I was kind of shocked by what I saw. This 295 pound 54 year old lost 74 pounds in 8 weeks. Isn't that insane? That's like twice the results of gastric bypass surgery. I'm less than her starting weight, but for me to lose 4 pounds a week, without considering exercise, I have to limit to around 1000 calories. So she was taking in something like 500 plus working out. I'm completely floored and jealous of course, but it's so fast. How fast is too fast? I yo-yo constantly with about 5 pounds. Obviously she did something that worked for her, but damn that's really fast weight loss.
