Viewing food as a system of biological signals helps explain why diets affect people differently and how nutrition can better support metabolism, mental health, and long-term well-being.

Michael S. Fenster, MD, FACC, known as Chef Dr. Mike, is an interventional cardiologist, professional chef, author, and professor of Culinary Medicine at the University of Montana. His work bridges clinical science, medicine, and gastronomy through a complex adaptive systems approach to diet and disease, drawing on fields including microbiology, neuroscience, information theory, and behavioral medicine. He is the founder and CEO of BridgMed, a digital health and culinary medicine platform focused on translating these insights into practical dietary guidance. He writes and speaks widely on food systems and the philosophy of health, and is the author of multiple books, including Dinner with God: Understanding the Language of Food.

Food is not a nutrition label.
Food is Information.
For decades, we’ve been told that health is a math problem—count the calories, balance the macros, optimize the nutrients. And yet chronic disabilities and diseases continue to rise, diets keep failing, and we’re more confused about food than ever.
What if the problem isn’t willpower…
What if it isn’t compliance…
What if the answer is not in another guideline…
What if the answer is not another macro or superfood…
What if we’ve been asking the wrong question altogether?
In Dinner with God, physician, professional chef, Professor of Culinary Medicine, and systems thinker Michael S. Fenster, MD, offers a bold, interdisciplinary re-framing of the relationship between food and health.
He moves us beyond the last half-century’s failed focus on only nutrients and the status quo’s outdated reductionist thinking. Applying the latest data and methodologies from complex adaptive systems thinking, he reveals food as a powerful informational system in which meaning shapes our biology and behavior, our health and our happiness.
Just as each of us speaks with a personal grammar shaped by history, culture, and experience, each of us eats with one as well. Over time, the foods we consume—how they are structured, timed, and combined—form a kind of dietary infosome: a unique pattern of signals our body learns to recognize.
These signals don’t just pass through us; they leave marks, influencing how our genes are expressed, how our metabolism adapts, and how resilient—or vulnerable—we become. In this way, food helps write our biological story, nudging us toward health, happiness, and longevity—or toward chronic disease, disability, and an early demise.
Drawing on medicine, culinary tradition, complex systems science, evolutionary biology, cultural history, and stories from across history, this book shows why two foods with equivalent nutrition labels can behave very differently in the same body—and why ultraprocessed foods disrupt health not simply because of what they contain, but because of how they corrupt our personal grammar.
At its core, Dinner with God explores a radical but deeply human idea:
Health emerges from relationships—not rules.
Inside, you’ll discover:
This is not a diet plan.
It’s not a list of foods to fear or rules to obey.
It is a new map—
one that treats food as a message, your body as an interpreter, and health as something that emerges when information is coherent, and our food-health relationship is strong.
Written for curious readers, clinicians, chefs, and anyone who senses that our current approach of Nutritionism has become stranded in the doldrums,Dinner with God invites you to step away from the contemporary noise and return to something older, wiser, and more durable: the shared human experience of eating as participation in a living world.
Because every meal tells a story.
The question is whether your body can still read it.
