With Master Your Metabolism, Jillian Michaels showed us how to take control of the metabolic machinery underneath our weight and health struggles. Now she's ahead of the curve again -- conquering the mayhem, myths, and misunderstandings associated with aging. After all, if you can decide your weight, why not your age?

Scientists and doctors have identified six major age inciters: metabolism, damaged macromolecules, epigenetics, inflammation, stress adaptation, telomeres.

The 6 Keys presents an ageless health, fitness, and beauty plan that addresses all six of them -- and gets them working for you instead of against you.

Empowering and rigorously researched, The 6 Keys outlines powerful lifestyle interventions, dietary guidelines, exercise plans, and vanguard strategies for cultivating mindfulness that restore and protect human performance, keeping you fit, healthy, and beautiful for life.
