Ok, so let me get this straight, you are saying that is good to eat a fast-acting carb (pasta, potato) before your workout? because in this book, he defnitely reccomends carbs during or after you workout. Im gonna take a guess that dextrose is not found in oats, or whole grains which are slower digesting carbs?
So, do I evevn bother having carbs for breakfast or before workout?
Berardi uses the phrase “nutrient timing”. In summary:
Energy Phase - 10 mins prior; then during workout = liquid P+C (e.g. whey+dextrose at 2:1 ratio)
Anabolic Phase - immediately after training = as above
Growth Phase - 1 hour after = as above (liquid at 1:1 ratio); 2 hours later = P+C meal at 1:1 ratio
Recovery Phases - 3-4 remaining meals of the day all P+F
Now when you train determines how these phases are arranged. A morning workout would match the outlay above. An afternoon workout, e.g. noon, would see you start in Recovery Phase mode with 1-2 P+F meals in the morning before starting the Energy Phase for the workout session. Finally, a evening workout, e.g. 6pm, is similar to afternoon with the exception that around 20-30g low GI carbs are pemitted for breakfast, with all other meals until the workout being P+F.
Regarding the liquid P+C workout drinks, Berardi recommends quite a high carb intake - especially if you’re a natural hardgainer. On average this works out at 40g whey and 80g fast-acting carb per drink. Recall you are having three shakes during this peroid (1st 10 mins before; 2nd during; 3rd immediately after) - not to mention another an hour after the workout at a 1:1 ratio followed later again by a P+C meal at 1:1. So your carb intake during workout days is pretty high, e.g. 320g. Obviously this is for mass gaining. Fat loss would require a sizeable drop in carb intake.
I hope this helps to clarify things for you. I have read Berardi’s works quite closely and, although no expert, I think I have a decent grasp of his core principles.
