Dr. Eric Westman sits down with Craig Emmerich, co-author of The Art of Metabolic Health, to discuss why metabolic health is often misunderstood by modern medicine and how low carb, keto, carnivore, protein, and fat-burning can change the way we think about chronic disease. Craig shares how his wife Maria’s health journey led them into the low carb world, why doctors still often fail to ask about food, how the body prioritizes alcohol, glucose, fat, and protein, and why ketosis is a normal metabolic state rather than something to fear. They also discuss dementia, kidney health, coffee, children’s nutrition, protein, and the power of real food in helping people take back their health.

Origin and background
- Maria’s IBS, acid reflux, PCOS, weight gain, and prescription-first medical visit made food the missing variable.
- A vet asked what the dog was eating, Maria saw that her doctor had not asked the same question, and low carb resolved her problems while she lost about 60 pounds.
- Recipe help became adoption fundraising, then more than 20 books; Craig later moved from engineering into biochemistry after Lyme disease led him deeper into carnivore.
Purpose of the new book
- The Art of Metabolic Health combines Maria’s practical protocols with Craig’s fuel-metabolism and biochemistry work.
- The book uses flexibility: keto, carnivore, and low carb sit on a spectrum, and any diet fails when people cannot sustain it.
- Recipe design, coaching, testimonials, and individual adjustment work alongside the science.
Fuel priority and ketosis
- Oxidative priority explains why alcohol burns first, glucose burns next, protein mainly supplies building blocks, and fat burns best when carbohydrate is low.
- The pancreas acts like a traffic cop, moving fuels through blood that normally holds only about 100-120 calories at rest.
- Sugar being burned early does not make it preferred; it reflects limited storage and higher risk when blood glucose runs too high.
- Low-carb eating lowers the need to burn incoming glucose, raises fat oxidation, and can improve satiety, energy, focus, and afternoon stamina.
- Ketosis is a normal human and mammalian metabolic condition seen with fasting and infancy, not an abnormal danger by itself.
Clinical signals and research gaps
- Testimonials point to research opportunities in early dementia, Alzheimer’s, Parkinson’s, IBD, kidney dysfunction, diabetes, obesity, heartburn, PCOS, and hypertension.
- Melissa’s assisted-living example moved from dementia-range testing to normal-range testing after six months of recipe-based eating with other modalities in the background.
- IBD moved from testimonials to a published case series, while kidney-function chart review work did not show damage from low-carb care.
- Protein comes first for amino acids, muscle, vitamins, minerals, and bioavailable nutrients, especially from animal foods.
Families, children, and friction points
- Children need direct instruction in cooking and food quality, not years of sugar and junk followed by an expectation that healthy eating arrives at adulthood.
- Coffee and caffeine can be harmless for many people, but sleep trouble, hunger, lipid shifts, mold, heavy metals, or immune stress make a coffee-free trial useful.
- The book serves readers, clinicians, nurses, students, coaches, and families seeking practical metabolic-health education outside usual medical training.
