I think she has done brilliantly and she should be applauded. In an interview I read with her, she said "It wasn't about diet, it was about exercise.." (but she would say that flogging her new DVD wouldn't she?!!!). Then she claimed she did her DVD for 50 minutes x 5 days a week.
I was angered when she said "I wasn't just fat, I was obese...my BMI was off the scale" yet she was claiming she was 10st 7lbs at 5ft 4in, which to my reckoning must only make her BMI less than 26! Hardly obese!!!
