Grant Hauth is a certified nutrition coach and metabolic health researcher based in Portland, Oregon. With a bachelor's degree in clinical nutrition from Oregon State University and a National Board Certified Health and Wellness Coach (NBC-HWC) credential, he has spent the past twelve years helping individuals navigate weight management, insulin resistance, and sustainable dietary change in both one-on-one coaching and group program settings.
Grant's approach to intermittent fasting grew out of his own health journey. After struggling with energy crashes, poor sleep, and stubborn weight gain despite regular exercise, he discovered that the timing of his meals—not just their content—was the missing variable. He experienced a fifty-pound weight loss over eight months using a structured 16:8 protocol and has maintained his results for six years. Those results, combined with a deep dive into the scientific literature, convinced him that intermittent fasting is one of the most underutilized tools in mainstream nutrition.
Before focusing entirely on intermittent fasting coaching, Grant spent five years working as a dietary consultant for employers and wellness programs, where he designed meal timing protocols for employees managing type 2 diabetes and prediabetes. His clients have included executives, shift workers, endurance athletes, and retirees, and his coaching philosophy emphasizes individualization—no two people need the same fasting schedule, and his programs are built around flexibility rather than rigidity.
Grant has written for the *Journal of Metabolic Health*, the National Board for Health and Wellness Coaching blog, and several online publications covering nutrition science. He has presented at the Northwest Health and Wellness Summit on the practical applications of time-restricted eating for metabolic syndrome. He lives in Portland with his wife and two children, where he experiments with fermentation, hikes the Columbia River Gorge, and drinks more black coffee than he's willing to admit.
*The Intermittent Fasting Blueprint* is his first book.
