I am going on holiday in October to meet up with old friends. I am ashamed to say that I have put on a humongous amount of weight since having my children. I need to lose at least 4 stone (5 stone to get back within healthy BMI range). Anyone manage to lose a lot of weight in a short amount of time. And which diets worked for you. I'm intending to go to the gym 5 days a week too. Thank you x
