Q

What is the impact of cardio on muscle preservation during a caloric deficit?

A

Low-intensity steady state (LISS) cardio is preferable during a caloric deficit as it burns calories without significantly increasing cortisol levels or competing for recovery resources. In contrast, high-intensity interval training (HIIT) can elevate cortisol and interfere with muscle recovery, making it less ideal for those looking to preserve muscle.

This is one answer. The complete system — the psychology, the biology, and the method — is in the book.
