Ben Palkulski, not that I think he his the brains behind much of his philisophies, and the members of his MI40 "team" also preach much of the same philosophy. They just had a You Tube video related to this topic.
I understand there are always a difference of opinion, but logically in my opinion it would seem to make sense to not blunt the affects from the training response. At the end of the day will this have a great limit/benefit on one's overall growth response, perhaps not, but if it is optimal then for me it makes sense to avoid those things. Especially since I can use them later in the day for the same benefits.
