So to recap, the Fast Diet was done for 12 weeks then a few more pre holiday (eating normally for 5 days a week, consuming approx 700 calories for 2).
I then lost weight whiles we were on holiday in Portugal (although I did eat cake as the hotel food was too good to say no to and I refuse to diet on holiday) but we walked tonnes, swam all day and I came back fitter and leaner than before we left.
