I've got 10 stone to lose and it is daunting but it was the best decision I have ever made, The only way to do this diet is stick to it 100% and change your way of thinking about food, this diet works as long as you do what you are meant to do. If necessary modify it slightly for you, e.g I still have a little skimmed milk whilst on sole source and it means that the diet keeps working for me.
It can be hard to stick to but remember you have a journey that you are starting on and that you have chosen to be on, the diet is a choice and a good one! Good luck to you and jeep us posted we're here if you need us! Xxx
