Protein — Everything You Need to Know

Donald Layman, professor emeritus of nutrition, unravels the intricacies of protein quality, timing, and intake, highlighting the benefits of animal-based proteins and the pivotal role of leucine. He offers insights on optimal meal timing and meeting protein needs, especially during intermittent fasting and as dietary requirements evolve with age.

  • Morning Protein

    The first meal of the day is crucial for muscle protein synthesis. emphasizes that consuming at least 35 grams of protein in this meal helps transition the body from a catabolic state to an anabolic one, promoting muscle growth 1. He also notes that while the first meal is essential, the importance of subsequent meals varies based on individual goals and activity levels 2.

    We know for 100% certainty that that first meal, and I'm sort of avoiding calling it breakfast because that implies that it needs to be super early or something. But whenever you choose to eat it, whether it's seven in the morning or eleven in the morning, that first meal needs to be high protein.

    Layman suggests that a high-protein first meal is vital, regardless of the exact time it's consumed.

       

    Post-Workout Protein

    Consuming protein after a workout aids in muscle recovery, especially for those new to exercise. Layman explains that while 15-20 grams of protein post-exercise can be beneficial for beginners, the timing becomes less critical for well-trained individuals 1. He also mentions that overall daily protein intake is more important than specific timing for seasoned athletes 2.

    If you're just beginning an exercise, you're out of shape, you're just beginning. Having protein 15-20 grams after your exercise within the next hour or so probably is a useful way to recover.

    For bodybuilders, spreading protein intake across multiple meals is recommended for optimal muscle growth.

       

    Intermittent Fasting

    Meeting protein needs during intermittent fasting can be challenging but manageable. Layman advises that protein synthesis mechanisms remain active for at least five hours, so meals should be spaced accordingly 2. He also highlights the importance of leucine in stimulating muscle protein synthesis, suggesting supplementation if necessary 3.

    We know that the mechanisms for regulating protein synthesis, once you turn them on, they're all active for at least 5 hours.

    Layman recommends distributing protein intake across two or more meals to optimize muscle growth and recovery.
