New York Times bestselling coauthor of the runaway bestsellers The Whole30 and It Starts With Food presents a paradigm-shifting plan that shows you how to boost energy, lose weight, and feel happier by living more in tune with the seasons.

Fatigue. Burnout. Weight gain. Disease. Despite seemingly endless programs designed to help us lose weight and regain our health, we are more overworked, overtired, and overweight than ever. In this groundbreaking book, bestselling author and health trailblazer Dallas Hartwig gets to the heart of why and reveals a powerful new program to help us feel happier, healthier, and less stressed.

Not many generations ago, our ancestors lived according to the changing seasons: they traversed long distances in summer, slept more in winter, gathered with family in the fall, and welcomed the warmer weather of spring as an invitation to be more active. But today, we are more disconnected from the natural world than ever. We wake before the sun rises and go to bed long after it sets. We spend most of our day indoors, in artificial light. We eat tropical fruits in the dead of winter. We exercise in climate controlled environments. We connect virtually instead of emotionally and physically. We are on the go nonstop, until we pass out, exhausted, at the end of the day.

In other words, we are living in a chronic summer, and it’s killing us.

Packed with crucial research and clear-eyed writing, The 4 Season Solution provides a new, sustainable model for living more in sync with the natural world. By making small but meaningful changes to the four keys of health—how you sleep, eat, move, and connect—over the course of the year, you will reclaim your health, regain your energy, and let go of excess weight. At once a bold philosophy and an accessible plan to live better all year long, The 4 Season Solution is a new health paradigm for an increasingly unhealthy world.
