I personally think that that is mad. Its great weight loss and well done Hannah Waterman but its mad. She will have cut out all carbs, alcohol, restricted herself to under 1000 calories a day and probably did around 2 hours of exercise a day to loose it so quickly. To maintain that she probably needs to read how Victoria Beckham maintains hers - 800 calories a day and an hours run or in perspective, a sandwich, a mars bar and a bag of crisps to us and a 3/4 mile walk a day! I cant see that doing anyone any good in the long term!
