What happens to nutrition science after the study is published?

Dr. Maya Maroto, EdD, MPH, RD, is Executive Director of the Coalition for Metabolic Health. A registered dietitian and certified ketogenic nutrition specialist, she has worked in academia, in nutrition policy and communications at the FDA and USDA, and on the food industry side at FoodMinds. Her own turn toward carbohydrate restriction began when a loved one with type 2 diabetes did not improve on the conventional advice she had been trained to give.

In this episode she joins Victoria Field and Dom D'Agostino to explain how research actually reaches policy: what changed in the new Dietary Guidelines for Americans, including first-ever language that people with certain chronic diseases may benefit from a lower carbohydrate diet; why guideline changes can take years to reach school meals and hospital menus; how congressional report language directed NIH institutes toward research on metabolic interventions for diabetes, obesity, cardiovascular disease, Alzheimer's, Parkinson's, and serious mental illness; and why, in her experience, the economic cost of chronic disease is what opens doors with lawmakers.

The conversation also covers keeping metabolic health bipartisan, how food industry messaging shapes what clinicians and consumers believe, why many dietitians remain cautious about ketogenic diets, what GLP-1 medications mean for nutrition-first approaches, whether carbohydrate restriction is affordable on a SNAP budget, and what metabolic psychiatry needs to move from promising science to rigorous research.

Questions Answered in This Episode:

• What actually changed in the new Dietary Guidelines, and why does the low-carbohydrate language matter?
• How long does it take for guideline changes to reach school lunches and hospital menus?
• How does congressional report language turn into NIH research funding?
• What persuades policymakers most: clinical data, patient stories, or the cost of chronic disease?
• Why are many dietitians cautious about ketogenic diets?
• Is therapeutic carbohydrate restriction too expensive for the people who need it most?

Listeners and viewers will come away with a clearer picture of the machinery between metabolic science and the policies that shape what Americans eat, and where clinicians, researchers, and patients can push it forward.

What would an emergency physician tell his patients if he could have met them 20 years before their crisis?

Dr. Michael Doney, MD, MPH, MS, spent years as a board-certified emergency physician managing the acute consequences of chronic disease. Today he is Executive Medical Director of Biograph, a preventive health clinic that combines whole-body MRI, cardiovascular imaging, DEXA, VO2 max testing, movement analysis, blood work, and genetics with a team of physicians, registered dietitians, exercise physiologists, and sleep specialists.

In this episode he walks Dom D'Agostino through how that data turns into a plan: why a high relative VO2 max can mask low skeletal muscle mass, especially in women in their late 40s and 50s; why Biograph talks about body recomposition, fiber, protein, and carbohydrate quality instead of weight loss alone; and what an internal study of about 1,000 members suggested about fatty liver disease in women, who in that cohort showed MASLD at lower BMI and visceral fat levels than men, with higher insulin resistance and fewer liver enzyme abnormalities. He also takes on the main critique of whole-body MRI, explaining how a standardized reporting system, subspecialty radiologists, and clinical context brought Biograph's reported referral rate for follow-up testing to about 5.4%, compared with the roughly one-third figure often cited.

The conversation also covers AI in imaging and in personal health data, diffusion-weighted MRI, a new study with Vero Bioscience tracking proteomic organ age through lifestyle interventions, mental health screening, how Biograph supports members already on GLP-1 medications, and what it would take to make this kind of prevention broadly accessible.

Questions Answered in This Episode:

• Why can a high VO2 max be misleading when muscle mass is low?
• How does Biograph turn dozens of diagnostics into one personalized plan?
• Why might fatty liver disease be harder to detect in women?
• How can whole-body MRI programs reduce false positives and unnecessary follow-up testing?
• What is proteomic "organ age," and can lifestyle change it?
• How should people on GLP-1 medications protect lean mass?
• Can preventive medicine become accessible beyond concierge care?

Listeners and viewers will come away with a clearer picture of what a comprehensive preventive assessment measures, where its limits are, and how the results translate into nutrition, exercise, and sleep interventions.

What happens when an internist teaches ketogenic nutrition to 200 students at the same time and tracks every one of their glucose and ketone readings on shared dashboards?

Dr. Annette Bosworth, MD, known to her audience as Dr. Boz, is an internal medicine physician and the author of ANYWAY YOU CAN and ketoCONTINUUM. After leaving corporate medicine she rebuilt her practice around ketone metabolic therapy, first with her own patients and now through a live 21-day class where small groups of ten work with coaches who have done the diet themselves.

In this episode she walks Dom D'Agostino through what that model has taught her: why every student does a 72-hour sardine fast and the changes she has observed in morning glucose and ketone readings the day after, how she started a medically supervised group already in ketosis on 0.6 mg of tirzepatide once weekly (approximately one-quarter of the labeled 2.5 mg starting dose) and her report that roughly nine in ten stayed at that dose, and why she asks every participant to keep their own physician involved

The conversation also covers the six-week ketogenic trial she ran with her mother during a leukemia recurrence, why she treats carbohydrate cravings the way she treated addiction in her clinic, and the free weekly support groups that classes from her first cohort still attend.

Questions Answered in This Episode:

• What has Dr. Boz observed during her 72-hour sardine challenges?
• What did Dr. Boz observe when using low-dose tirzepatide in patients already in ketosis?
• What does "relief, not joy" reveal about carbohydrate addiction?
• Why can blood pressure medications require reassessment when starting a ketogenic diet?
• Why does she emphasize physician involvement when participants take prescription medications?
• Why does she combine group coaching with glucose and ketone tracking?

Listeners and viewers will come away with a practical picture of ketone metabolic therapy as it is actually delivered: the protocol, the monitoring, the medication monitoring and reassessment, and the community structure that keeps people in it.
