We've designed the plan in such a way that so long as you stick to 2 x juices and 4 x protein smoothies per day you are all set.
You can enjoy them in any order you wish. There is no peer-reviewed scientific evidence to support having drinks in a certain order.
The only recommendation we would make is that you avoid caffeine-based drinks (Morning Glory & Higher Energy) after 5pm - unless you have some adventurous all-night plans!
