Huberman Lab Clips2 minutes read

Dr. Layne Norton suggests a protein intake of 1.6 to 2.7 grams per kilogram of body weight for hypertrophy, with a focus on broad protein and carbohydrate intake post-workout to simplify dietary considerations and optimize growth and recovery. Carbohydrate timing is essential for muscle glycogen replenishment, with different protein to carbohydrate ratios recommended based on the type of workout, including a three to one ratio for hypertrophy training.

Insights

  • Dr. Layne Norton recommends a protein intake range of 1.6 to 2.7 grams per kilogram of body weight per day for hypertrophy, simplifying dietary considerations by focusing on protein quantity rather than quality, type, or timing.
  • Post-workout, carbohydrate timing is crucial for muscle glycogen replenishment, with varying protein to carbohydrate ratios recommended based on the type of workout, emphasizing the importance of carbohydrates in optimizing growth, recovery, and performance.

Optimizing Muscle Growth with Protein and Carbs

  • Dr. Layne Norton recommends a protein intake range of 1.6 to 2.7 grams per kilogram of body weight per day for hypertrophy.
  • Post-hypertrophy workout, a broad window exists for protein and carbohydrate intake, contrary to previous beliefs of a narrow feeding window.
  • Layne Norton suggests a protein intake of about 1 gram per pound of body weight, equivalent to 2.2 grams per kilogram.
  • Maintaining a high protein intake negates the need to focus on protein quality, type, or timing, simplifying dietary considerations.
  • Carbohydrate timing is crucial for muscle glycogen replenishment, with a one to one protein to carbohydrate ratio recommended post-strength workouts.
  • For intense conditioning workouts, a higher carbohydrate to protein ratio of three to four to one is advised.
  • In pure hypertrophy training, it is beneficial to consume carbohydrates post-workout to optimize growth and recovery, with a three to one carbohydrate to protein ratio suggested.
