Food prep day is actually worse than being on the Plan itself. If you’re reading this and are wondering about the food prep (this is just for days 1-3), it does take a while despite how the book says it’s so simple.
Figuring out and buying the ingredients takes effort since there’s no (accurate) grocery list in one place. If you have time, I recommend testing out some recipes before so you have an idea of what’s happening and how the food will taste. Otherwise, it is totally doable in a day on the first try but it will be time consuming for sure. Plus some of the recipes might taste a little “off” since the seasonings are to taste.
