I have tried every diet under the sun from being 15 years old to 72. Some worked for a while , some were too awful to stay on , others made me slim short term and then I gained even more weight . A neighbour told me about the Fast 800. I was cynical at first - I feared that making interesting food would make it even harder . But the recipes are so easy , tasty and easy to adapt for the rest of the family. The exercise programme is great too - tailored to you and your needs. The back up service when you have a query ( however daft) is terrific too - they come back to you in 48 hours and are always kind and sensible. I have now lost the 1stone 8 lbs I have tried to shed for 57 years. My arthritis in knee and hip Is SO much better. I feel energised , optimistic happy. The challenge now is to keep it off and eat sensibly - working out how to enjoy and how to cut back as naturally slim people do . This really is the best scheme ever - wish I have discovered it years ago.
