Good question!
On a CKD or ANPB diet would it be better off to just drink a Whey Isolate drink Post Workout? Or still combine some carbs ?
Currently, post workout I'm consuming a protein drink (Worldwide PureProtein) which contains 41g of Protein Isolate and zero carbs (about 180 cals), after about an hour I would eat my usual ANPB meal. I guess the lake of carbs post workout is beneficial for a continued lipolisys post workout. The insulin response following carb intake would probably completely halt lipolysis.
On the other hand, carbs post workout (such as dextrose/maltodextrin) in combination with whey isolates are very efficient for enhancing protein synthesis and aminos absorption.
Lately, I'm into the notion of replacing my whey only drink post workout to a drink called 'Rapid Recovery' which contains:
Cals: 280
Carbs:32g (Maltodextrin: 22g, Glycerol:10g)
Protein: 34g (from whey isolates)
Fat: 0g
I think that would give the slight boost needed without overloading too many with carbs.
