different cabbage soup diet plans

I'm confused can you take protein shakes every day and skimmed milk and yoghurt every day, I checked out the old version and was all set but now I've found the new version and am confused.

Hi MC,
there exist different cabbage soup diet plan versions, it's up to you which one you prefer.
If you take proteinshakes twice a day you are not allowed to take skimmed milk/yoghurt in addition -the same is true vice versa.

All the best,
Gabriela
