Who else wants to know what happens after Forever's Clean 9 Diet? Well, lots of us move on to F15, a 15-day programme to consolidate all the good work done with Clean 9. There are essentially 3 options - F15 BEGINNER, F15 INTERMEDIATE and F15 ADVANCED. Here you'll find the charts helping you decide which of these you are. It all begins with Clean 9 and Forever FIT!
