What does this mean in practice?

In practical terms, this simplifies planning. You don't need to rush to the locker room with a shaker bottle. You don't need to restructure your meals around your gym schedule. And you don't need to feel guilty about training legs only once a week if that fits your life.

What should you do next?

Focus on total daily protein first. Aim for roughly 1.6–2.2 grams per kilogram of body weight, spread across your meals. For a 75 kg... Don't stress about the 30-minute window. Eating protein within a few hours of training is fine. So is eating it at any other time. Pick a training split that fits your schedule. Full-body 3x/week or a dedicated split (hitting each muscle once per week on its own day)...

The 'Anabolic Window' Is Mostly a Myth — Here's What Actually Matters

You've probably heard you need to drink a protein shake within 30 minutes of your last rep or your workout is wasted. Gym culture treats this 'anabolic window' as essential. But when researchers controlled for total daily protein intake, the timing effect disappeared entirely.

Total daily protein intake matters far more than when you eat it relative to your workout.

What the Research Found

Researchers combined data from 23 studies (525 people total) in a large review. They examined whether eating protein right around your workout builds more muscle than eating it at other times. The simple comparison seemed to favor workout-timed protein for muscle growth.
