Food Optimising is the name given by Slimming World to their highly successful weight-loss technique that enables slimmers to lose weight without ever having to go hungry. It is the most slimmer-friendly eating system there is and is based on a deep understanding of the challenges faced by overweight people - no foods are banned, there is no calorie counting and there are hundreds of 'free foods' that can be eaten in unlimited amounts. I bought this as a guide so I could help my learning-disabled adult daughter lose weight while still being able to enjoy tasty food. It is less helpful than some books since it measures food values in "syns" and a Food Optimising code, which I don't understand, having never been to a Slimming World session. There is some explanation of this system in the book but at first glance it doesn't make much sense. However, it has value in that it does offer some lovely recipes so we will use it.
