Research sponsored by Slimming World, published in 1996, shows that of the major food groups, foods rich in protein or carbohydrate are the most effective in satisfying appetite and keeping us full for longer. There are only around four calories to every gram of carbohydrate and protein, while a gram of fat contains nine calories. And because fat is least effective at satisfying appetite, it's all too easy to eat far more than our bodies require.

The well established Green and Original choices make it easy for slimmers to fill up and stay full on their favourite foods. All they have to do is choose whether they want to follow:

The Green choice - which includes unlimited filling and healthy foods rich in carbohydrate, such as pasta and potatoes as well as protein-rich foods like lentils and pulses and measured amounts of meat, fish and poultry, bread, cereals and dairy products.

The Original choice - which includes unlimited satisfying protein-rich foods such as lean meat, fish and poultry as well as fresh fruit and vegetables and measured amounts of other carbohydrates like pasta, rice, potatoes, bread and cereals as well as dairy products.

And now, Food Optimising has two brand new choices…

With Mix2Max slimmers can mix Green and Original the same day, choosing at each meal time instead of each day, and there’s still a long list of foods that slimmers can snack on throughout the day too!

Success Express has been specifically developed to give existing slimmers a super boost to their weight loss. With Success Express slimmers can have Green and Original Free Food on the same plate. Following a neat ‘Two to One’ plate principle, slimmers choose from Green or Original Free Food lists and fill one third of the plate with what ever they choose. The other two thirds of the plate is filled with Superfree Foods (super healthy, super low in energy density foods) such as vegetables and salad, and still a long list of foods that slimmers can snack on throughout the day.
