Diet & Supplementation for Muscle Growth | Dr. Andy Galpin & Dr. Andrew Huberman

Summary

The video discusses optimal protein intake for muscle growth, recommending 1g per pound of body weight as a minimum. It notes the importance of overall protein quantity rather than precise timing or quality. For strength training, a 1:1 ratio of protein to carbs is advised post-workout. For endurance a 3-4:1 carb to protein ratio is better. For hypertrophy training, nutrient timing is less important than sufficient overall intake, though spreading meals and nutrients pre, mid and post-workout is ideal. A 3:1 carbohydrate to protein ratio is suggested.

Takeaways

• 📊 The recommended protein intake for hypertrophy ranges from 1.6 to 2.7 grams per kilogram of body weight per day, with some suggestions going as high as 1 gram per pound.
• 🚴‍♂️ Protein quality, type, and timing become crucial factors when intake falls below recommended levels, adding complexity to nutritional planning.
• 📈 Higher protein intake simplifies dietary considerations, reducing the need to focus on the specifics of timing, types, and quality of protein.
• 💪 Total protein intake is paramount; the significance of protein timing and specific amino acid content diminishes when overall protein consumption meets or exceeds recommended thresholds.
• 🚲 Nutrient timing for carbohydrates is important for replenishing muscle glycogen, especially in endurance training or maintaining high-quality training sessions.
• 📪 A balanced post-exercise nutrition strategy might include a one-to-one ratio of protein to carbohydrates for strength-focused workouts, with adjustments based on the intensity and type of training.
• 👍 Including carbohydrates in post-training meals for hypertrophy is beneficial, aiming for a ratio that supports recovery and growth.
• 🏋️‍♂️ Personal preference plays a significant role in the timing of nutrient intake around workouts, with some people preferring to eat before, during, or after exercise.
• 📝 The consensus is that fueling around training sessions offers potential advantages for muscle growth and recovery, with no known benefits to fasting around workouts.
• 💦 For pure hypertrophy training, distributing nutrient intake evenly throughout the day and around workouts maximizes growth potential and jumpstarts recovery.

Q & A

What is the recommended range of protein intake per kilogram of body weight for hypertrophy according to Dr. Layne Norton?

Dr. Layne Norton recommends a range of 1.6 to 2.7 grams of protein per kilogram of body weight per day for hypertrophy.

How does protein intake vary with different dietary choices such as omnivore or vegan diets in the context of hypertrophy?

The discussion suggests that dietary choices (omnivore, vegan, etc.) affect how one might reach their protein intake goals, but it emphasizes the importance of meeting the protein intake range regardless of diet.

What is the significance of spreading out protein intake throughout the day?

Spreading out protein intake is important to accommodate the body's limited capacity to assimilate protein in any given setting, maximizing protein synthesis.

What is the role of post-workout nutrition in muscle protein synthesis and recovery?

Post-workout nutrition, including both nutrition and supplementation, is crucial for facilitating muscle protein synthesis and recovery after a hypertrophy-inducing workout.

Has the concept of the post-training feeding window changed over time?

Yes, the understanding of the post-training feeding window has evolved from being within the first 30 to 90 minutes to a much broader timeframe, although the exact duration is still debated.

What is the equivalent of 1 gram of protein per pound in grams per kilogram?

1 gram of protein per pound is equivalent to approximately 2.2 grams per kilogram.

Why does Andy Galpin agree with Layne's recommendation on protein intake?

Andy Galpin agrees with Layne's recommendation because a higher protein intake simplifies other nutritional considerations like protein quality, type, and timing.

How does nutrient timing differ between carbohydrates and proteins according to Andy Galpin?

Nutrient timing is somewhat irrelevant for proteins, assuming total protein intake is high, but it is very specific and important for the replenishment of muscle glycogen with carbohydrates.

What is the recommended protein to carbohydrate ratio post-exercise for strength work?

For strength work, a one to one post-exercise protein to carbohydrate ratio is recommended, like 35 grams of protein to 35 grams of carbohydrate.

How does Andy Galpin suggest adjusting carbohydrate intake based on the type of workout?

For hard conditioning workouts, the carbohydrate to protein ratio should increase to three or four to one. For a mix of strength and conditioning, a two to one ratio is suggested.
