Does alcohol actually slow progress?
Yes, mostly through what it costs you elsewhere. It adds calories that don't fill you up, it wrecks sleep quality even when it knocks you out fast, and heavy or regular drinking is linked to lower testosterone. None of that shows up on the label, only in how you feel and perform the next day.
Why did you stop drinking?
It has been over 14 years since I had a drink. It was a personal choice, not a rule I'm handing you. I'm not here to vilify alcohol or tell anyone not to drink.
Does it have to be zero?
No. Guests on the podcast have described real changes without going to zero: clearer thinking, more stable mood, better training the next day. The line that matters is moderate versus overindulging, which is where the testosterone and recovery hit shows up.
What is a reasonable place to start?
Track it for two weeks like you would food. Most men are surprised by the actual count. Cut the midweek drinks first, since those cost the most sleep before a training day.
