Absorption of Protein

Tim Ferriss has touched upon the topic of protein absorption in various podcasts. Here are some key insights:

1. Bolus Feeding for Older Women: In one study discussed by Ferriss, older women absorbed protein more effectively when consuming a large amount (70-80 grams) in a single feeding rather than spreading it out over several meals throughout the day. This finding suggests that a larger bolus of protein might enhance absorption and effectiveness in this demographic 1.

2. Protein Needs and Recommendations: Ferriss and Dr. Peter Attia critique the recommended daily allowances (RDA) for protein, suggesting that these guidelines are too low. They argue that optimal protein intake should be closer to 2 grams per kilogram of body weight (about 1 gram per pound), rather than the RDA of 0.8 grams per kilogram. This higher intake is proposed to support thriving rather than just surviving, especially for maintaining muscle mass and preventing frailty 2.

These points highlight the importance of sufficient protein intake and how different strategies can affect absorption and utilization in the body.
