Description
Do you need to keep your health concerns separate from your faith, or is health one of God’s concerns, with Biblical mandates to care for your body? Do you need to practice constant self-denial to have a healthy diet, or did God make your appetites for a reason? Does caring for God’s creation require increasingly more government control and spending like modern environmentalists advocate, or has God provided another route? Is dairy an unnatural food for humans? Do you need to avoid all grains? Or did God commission us with dominion over creation that allows us to raise and prepare glorious, nourishing foods for the benefit of man and creation?
Christians eat every day. Christians make decisions about food every day. And if you’ve ever listened to Christians sharing prayer requests, you know that health problems are a top concern for Christians. Yet few resources give Christians practical guidance, grounded in a Biblical worldview, on navigating food and nutrition. We would be led to believe that worldly advice about health is entirely secular and scientific, but this book reveals how modern beliefs about nutrition are rooted in evolution, humanism, and false religious worldviews, which inevitably mislead people into the chronic disease crisis we are contending with now.
While conventional approaches to nutrition teach that man can supersede God’s natural order and treat the human body like a machine, alternative approaches often take an evolutionary approach that recommends mimicking the lives of hunter-gather ancestors. There is no spiritual neutrality in food and nutrition. It’s time to replace the world’s ascetic, restrictive, and ineffective approach to nutrition with food-loving, creation-honoring, dominion-taking, Christian nutrition.
In Eat by Faith, Functional Nutritional Therapy Practitioner Kat Owens lays a foundation for answering the question of “what is the ideal human diet” and then applies that foundation in practical detail to all the major divisions of foods. Using a Biblical worldview, science, and human history, Owens provides an approach to healthy eating that is deeply joyful, unrestrictive, ordered, and incredibly effective.

Mrs. Owens’ provides a hopeful recovery of God’s good gift of food, along with a highly practical approach to health in our confused era of allopathic hopelessness, lone gurus & Darwinian food myths. She presents a faith-filled, anti-gnostic answer to the shallow philosophies of nutrition in the modern church. The commonplace consequences of poor nutrition and health habits have many in dire straits, but this Biblical treatment of food wisdom can revitalize generations. Eat By Faith is an essential read for Christians seeking to recover a practical and victorious recovery of regenerative health. Such an approach will brighten your family’s future as you glorify God in all things, starting with the simplicity of eating and drinking (1 Cor. 10:31).

In Eat by Faith, Kat Owens brings a distinctly Christian clarity to a subject long ceded to secular voices. Rooted in the authority of Scripture and shaped by a robust doctrine of creation and dominion, this work calls believers to glorify Christ even in the ordinary act of eating. Owens reminds us that the lordship of Jesus extends to our tables, our stewardship of the body, and our care for creation. This is a needed, theologically grounded correction to an all-too-common neglect of embodied discipleship.

We’ve long been told ideas have consequences. But what if eating has consequences, as well? What if a host of problems in our families and churches flow out of our rejection of the Creator and His creation? What if our faith isn’t irrelevant to our plate? What if love for self, neighbor, and nature calls us to step back and reevaluate building our lives around cheap foods that come at a high cost? I hope Kat’s book is the start of many that tackle these tough questions and that get Christians to take seriously the cost of not stewarding all the good gifts God has given us well and according to their purpose and design.

As a Christian herbalist, I’ve often wanted a solid nutrition book to recommend to clients, students, and friends, but always felt disappointed. Most nutrition experts look at food through an evolutionary lens and deny the Bible’s creation account. This leads to popular diets that might yield some good results, but are on a shaky philosophical foundation. If we didn’t descend from crude hunter-gatherer cavemen, does the Paleo diet really make sense? Yet Christian sources can veer into the realms of overly restrictive diets like vegetarianism, trying to recreate the Garden of Eden. Perhaps worse, they may fall into the trap of declaring dietary habits a thing of no concern to the believer, since these bodies will die regardless of what we eat. No wonder Christians have been confused for so long! But Kat Owens has stepped in with Eat by Faith, finally giving Christians the Biblical, historical, and scientific guidebook on food and nutrition that I’ve wanted for so long. It’s a must-read for any believer who wants to steward their temples for God’s glory.

Eat by Faith is a refreshing and thoughtful reminder that nutrition does not have to be separated from faith. Kat Owens beautifully connects biblical principles with practical wisdom about food, encouraging readers to see nourishment as an act of stewardship and gratitude for God’s creation. In a world of confusing diet trends, this book brings clarity, conviction, and hope.

As a Christian physician who incorporates holistic medicine, nutrition, and lifestyle into patient care, I was genuinely excited to read this book. Eat by Faith is already on my recommended reading for my patients. While Owens writes from a Christian worldview, the nutritional insights and practical recommendations are relevant for anyone interested in improving metabolic health.
In my medical practice I see the metabolic consequences of modern industrial “foods” and the SAD (Standard American Diet). This book skillfully integrates scientific reasoning with historical and Biblical wisdom, rather than simply following current dietary trends or the often-flawed recommendations of organizations like the ADA and AHA. Kat is systematically chipping away at outdated and disproven nutritional advice in every chapter and I’m completely on board.
Near and dear to my heart as a Montanan is the discussion of whole-animal nutrition which is responsible stewardship and most nutritious. Owens also raises important questions about modern food production and the positive role of regenerative agriculture in restoring healthier systems. I would recommend this book to readers interested in regaining health the way God intended, nutrient-dense whole foods, preparing our own meals, regenerative agriculture, and a broader understanding of how soil, plants, animals, and human health are connected.
Dr. Jess Restrepo, D.O.
Eat by Faith is a thoughtful and heartfelt invitation to slow down and consider how our food choices reflect what we believe about God, creation, and stewardship. Kat Owens brings together Scripture, lived experience, and careful research to challenge the way Christians often separate faith from daily nourishment. In a world full of noise and confusion around food, this book encourages a more intentional, grateful, and grounded approach to eating that supports both family life and faithful living. It’s a meaningful contribution that will prompt reflection, conversation, and a deeper sense of purpose at the table.
