Post-Workout Nutrition, Antioxidants, and Insomnia’s Health Risks: Leyla Muedin, a registered dietitian in New York City, answers listener questions about post-exercise nutrition, advising against sweet or high-carb foods immediately after workouts because they raise blood sugar and insulin, shift the body back to fat storage mode, and can blunt human growth hormone needed for muscle and bone repair; she suggests protein and fat after morning exercise and saving carbohydrates for later, ideally 3–4 hours post-workout or at dinner. She also addresses concerns about oxidation after exercise, recommending antioxidant nutrients (vitamin C, mixed tocopherols/tocotrienols, vitamin D) and vegetables like spinach, onions, and mushrooms, noting inflammation and microtears are part of training adaptation. Finally, she discusses research linking insomnia to higher stroke risk and hospitalization, and reviews possible causes and sleep hygiene, plus options like melatonin, L-theanine, magnesium, and herbal ingredients.

Nutritional Support for Mood: Magnesium, 5-HTP, Adaptogens, and the Folic Acid Debate: Dr. Ronald Hoffman interviews Neil Levin of NOW Foods/ Protocol for Life Balance about rising depression and anxiety and the roles of lifestyle, social media, stress, diet, sleep, and exercise in mood. They discuss nutrient cofactors for neurotransmitter production, emphasizing B vitamins, magnesium, zinc, omega-3s, and gut health/fiber, plus concerns about heavy metals like lead and possible links to mood and violence. Levin contrasts tryptophan vs 5-HTP (blood-brain barrier, dosing, serotonin/melatonin) and reviews supplements for mood support including magnesium glycinate and magnesium threonate (Magtein/Cogumin), ashwagandha KSM-66 for stress and sleep, inositol (often gram-level dosing; PCOS and neurotransmitter effects), and GABA/PharmaGABA. They also address controversy over folic acid fortification, arguing folic acid is proven to reduce neural tube defects, methylfolate marketing has caused misinformation, and very high folate doses may warrant caution in active cancer.

Dr. Ronald Hoffman interviews pediatrician and public health expert Dr. Megan Moreno, co-author of “ Connecting: Raising Kids in the Digital World ” and co-medical director of the American Academy of Pediatrics Center of Excellence on Social Media and Youth Mental Health, about how social media and technology affect children’s mental and physical health. They discuss evidence linking tech use to sleep disruption and mixed effects on nutrition and physical activity, plus risks including body image comparisons, addictive “frictionless” design in social media and gaming, exposure to disturbing content, cyberbullying, sexting, and impacts of parent device use on connection and language development. Moreno outlines practical, non-punitive strategies: assessing readiness for a phone based on maturity, setting rules on time and location, co-viewing, using device settings with role modeling, watching for problematic use, and maintaining open, supportive conversations.

What to Eat After a Fasted Workout—and Why Energy Drinks May Affect Heart Rhythm: Registered dietitian nutritionist Leyla Muedin discusses what to eat after exercise, especially morning fasted workouts, advising water first and avoiding sweet or carb-rich post-workout options (smoothies, bananas, flavored yogurts, cereal, sports drinks) because they can raise blood sugar and insulin, reduce fat burning by suppressing glucagon, and blunt exercise-related benefits like human growth hormone; instead she recommends a savory protein-and-fat meal (e.g., a 3–4 egg omelet, steak, chicken salad without bread) within 45–60 minutes to support muscle repair while keeping insulin low. She then reviews a 2025 systematic review of 37 studies (1,597 participants; average age 22.5) in which 63.2% of studies reported QT prolongation after energy drink consumption, with frequent increases in blood pressure and heart rate, noting that the findings show repeated measurable cardiovascular changes but do not prove energy drinks cause heart disease.

Preventive Medicine and the “Preventioneers”--From Benjamin Franklin to Modern Public Health: Dr. Ronald Hoffman interviews public health physician Dr. Barry Davis, MD-PhD, author of " The Preventioneers: Diseases, Disasters, and the Discoveries That Changed Our World ," about why preventive knowledge often fails to translate into action. Davis explains Benjamin Franklin’s “ounce of prevention” quote originated in fire prevention and led to innovations like fire companies, building codes, lightning rods, the Franklin stove, and fire insurance. They discuss hypertension as a “silent killer,” the VA clinical trials proving blood-pressure lowering prevents strokes and heart attacks, and the modern gap in awareness and control, alongside systemic barriers like access, adherence, and clinical inertia. Davis outlines a prevention framework—recognition, evidence, translation, implementation—and persistent resistance from industry, addiction, glamour, and the “invisibility problem,” noting only 2.9% of U.S. health spending goes to prevention. They cover clinical trials, peer review, bias, confounding, Mendelian randomization, statin evidence, Semmelweis and handwashing, seatbelt adoption, AI as an emerging prevention challenge, and rebuilding public trust after COVID through better communication and coordination.

Nitric Oxide: Supporting Vascular Health, Performance, and the Oral Microbiome with Dr. Nathan Bryan: Dr. Ronald Hoffman interviews nitric oxide researcher and entrepreneur Dr. Nathan Bryan about nitric oxide (NO) as a short-lived signaling gas that dilates blood vessels, reduces inflammation, mobilizes stem cells, supports mitochondria, and is linked to longevity. Bryan explains two NO production pathways: nitric oxide synthase from L-arginine and an entero-salivary nitrate pathway requiring dietary nitrate, specific oral bacteria, and stomach acid; he says sugar-heavy diets, fluoride toothpaste, antiseptic mouthwash, and proton pump inhibitors inhibit NO. Symptoms of deficiency include erectile dysfunction, rising blood pressure, metabolic disease/diabetes, exercise intolerance, and dementia/Alzheimer’s. They discuss limitations of many beet products, Bryan’s N-101 lozenges and NOBeats powder that generate NO, topical NO for wound healing and skincare, a fluoride-free prebiotic toothpaste, an upcoming mouth rinse, potential benefits for resistant hypertension, insulin resistance, cognition, and eye conditions like glaucoma, and access/discount details via hoffmannno.com.

Time-Restricted Eating Study: Nutritionist Leyla Muedin details a Johns Hopkins Medicine study (published July 27 in Obesity) on time-restricted eating (TRE), a form of intermittent fasting that limits eating to a consistent 8–10 hour daily window, in adults with obesity and prediabetes or diet-controlled type 2 diabetes. In a 12-week trial of mostly female and Black participants, groups followed either a 10-hour TRE schedule or a usual 16-hour eating pattern, while all received a provided, personalized-calorie DASH diet intended to maintain starting weight. Both groups experienced similar modest weight loss and reported improved eating behaviors (more restraint, less stress eating, less hunger), with no differences in appetite hormones (ghrelin, leptin) or inflammation markers (CRP, cortisol). Leyla argues a higher-carb DASH diet may have limited measurable benefits and suggests repeating the study with a true low-carbohydrate diet; she also explains how fasting periods can lower insulin, support fat burning, and improve sleep by avoiding late meals.
