Hiya!
Basically it's the same, although attack is a bit stricter: no tolerated items (goji berries, onion, fruit yoghurt, cocoa...) and only 1.5 tbs oatbran. In cruise that increases to 2 tbs, and you can add a certain quantity of items on the 'tolerated' list (check the book or the website for details as these do seem to change over time).
Good luck and keep us posted!
