Episode Highlights

  • Protein Needs

    Protein plays a pivotal role in maintaining muscle mass, especially as we age. emphasizes that older adults require more protein per kilogram than younger individuals due to decreased anabolic hormone levels, which affects muscle protein synthesis 1. He suggests a safe intake of 1.2 to 1.5 grams of protein per kilogram daily, noting that higher consumption has minimal adverse effects unless pre-existing renal issues are present 1.

    When we put healthy old people on that amount of protein and give them the calories they need to maintain their weight, they lose muscle.
