I don't do ckd. but, after cardio, I have a lot less carbs andprotein that normal. I have a shake w/ 35g Protein and 15g sugar 30 min post cardio. Then an hour later my normal breakfast. This is what I do after morning cardio on non-lifting days. On lifting days, I do 30 min cardio after lifting, so I have the standard high carb+high protein shake, about 60g protein and 40g(I have about 75-100g low-glycemic carbs about an hour before training... so I don't need crazy amt's of carbs) carbs. This is what works for me.
