Even ~2 drinks can disrupt REM sleep.*
Higher alcohol intake after training has been shown to reduce muscle protein synthesis.*
You don’t have to quit drinking.
But the trade-off is real.
Can you drink alcohol and still make progress? Yes.
But if you’re training hard, trying to build or preserve muscle, improve body composition or recover better, it’s worth understanding the trade-off.
Here’s what the research tells us:
🍷 Sleep: A 2025 review of 27 studies found that even relatively low alcohol intake, around 2 standard drinks, can reduce REM sleep. The disruption increased as alcohol intake increased.
💪 Muscle: In one post-exercise study, a high dose of alcohol reduced muscle protein synthesis by 24% even when participants consumed protein. Important context: this was a very high alcohol dose, so it does NOT mean two drinks reduces muscle growth by 24%.
🏋️ Recovery: A systematic review of research following resistance exercise found alcohol was associated with lower muscle protein synthesis and testosterone and higher cortisol, although measures such as force, power, muscular endurance and soreness weren't consistently affected.
And then there’s the simplest piece: alcohol adds calories that may or may not fit your current nutrition goals.
The point isn’t “don’t drink.”
It’s: Know the trade-off.
If you’re frustrated with your progress, look at the whole picture. Training, protein, total intake, sleep, recovery AND alcohol all count.
That’s nutrition coaching. Not restriction. Better awareness and better decisions based on your goals.
