I have a question about this episode 235‒Training principles for mass & strength, changing views on nutrition, & creatine supplementation and this Protein and Fasting What does Dr. Peter Attia say about fasting?

In the episode "235‒Training principles for mass & strength, changing views on nutrition, & creatine supplementation" of the The Peter Attia Drive Podcast, Dr. Peter Attia discusses fasting, particularly intermittent fasting, and its impact on protein intake. He stresses the importance of not compromising protein intake while using fasting as a tool for energy restriction. Dr. Attia mentions that although intermittent fasting can reduce energy intake, there is a caution against allowing it to lead to inadequate protein consumption. He notes that this approach should not be dogmatic and suggests that flexibility, such as having a protein shake outside of the designated feeding window, can be beneficial. This flexibility can help maintain protein levels without undermining the fasting goals. Additionally, he expresses skepticism about achieving significant autophagy within a typical 16-hour fasting period, suggesting that such processes are unlikely to be meaningfully activated within this duration 1.
