According to the Exante website;
Why do I have do have a food week break whilst on Total Solutions?
You must have the food week break every 28 days as you are following a VLCD, such as the Total Solution, without medical supervision.
During your food week break you will still have 3 meal replacements a day as well as a healthy balanced meal that is between 400 – 600 kcals. We recommend high protein / low carb meals. Any white meats, fish with green vegetables or salads.
It is also a good way of getting used to counting your own calories and eating healthy balanced meals.
