Ultrametabolism

Hyman's focus on metabolism feels different from typical diets. I'm curious what led him to prioritize this approach over calorie counting or exercise alone.

Some of the food choices seem straightforward, but sticking to them might be tough in everyday life. How have others managed to make these changes sustainable?

Hyman presents certain routines as almost effortless. I wonder what process he used to identify these habits as the most effective and easy to adopt.
