Featured Intermittent Fasting Experts

I am a Registered Dietitian Nutritionist, Certified Diabetes Care and Education Specialist (CDCES), and Certified Personal Trainer with a telehealth private practice specializing in diabetes management, pre-diabetes prevention, weight management, and PCOS. My clinical expertise spans Type 1 diabetes, Type 2 diabetes, pre-diabetes, insulin resistance, PCOS, and cardiometabolic health. I am one of a small number of practitioners who holds both the RD and CDCES credentials alongside a personal training certification — allowing me to address nutrition, glucose management, and exercise strategy as a single integrated plan rather than three separate referrals. I have a particular focus on the Asian and Asian American community, where Type 2 diabetes is significantly underdiagnosed and undertreated. Asian individuals develop insulin resistance and Type 2 diabetes at lower body weights than standard screening guidelines typically account for — meaning many Asian patients are told their numbers are "fine" long after their metabolic health has begun to shift. As a Taiwanese and Hong Kongese practitioner fluent in Mandarin and Cantonese, I provide culturally informed care that meets clients where they are — including nutrition guidance built around Chinese, Taiwanese, and Cantonese food traditions rather than asking clients to abandon the foods that are central to their culture and family life. I am available to comment on topics including: Blood sugar management and glucose pattern interpretation CGM (continuous glucose monitor) use and data literacy GLP-1 medications — nutritional considerations and muscle preservation Pre-diabetes reversal and prevention strategies Diabetes and exercise — including resistance training and cardio's effect on glucose PCOS and insulin resistance Medical nutrition therapy and the role of the RD in diabetes care Disordered eating and complicated relationships with food in the context of chronic illness Diabetes risk in Asian and Asian American populations — why standard BMI cutoffs miss the mark Culturally informed nutrition care for Chinese, Taiwanese, and Cantonese communities Bilingual nutrition counseling in Mandarin and Cantonese Telehealth nutrition care and multi-state practice Weight management without restriction Available for: quotes, expert commentary, podcast interviews, article contributions, and media features — in English, Mandarin, or Cantonese.

As a NASM Certified Nutrition Coach (CNC) at Same Day Supplements, I specialize in providing science-backed, personalized nutrition guidance to help individuals achieve their health and fitness goals.

I've dedicated my life to fixing gut health issues, balancing hormones, and tackling heart and energy problems from the root cause—not just masking symptoms with endless meds. My own story started young: At age 10, a bad infection from travel nearly took my life due to a wrong antibiotic, sparking my passion to help others avoid that pain. Later, in my 40s, I battled fatigue, weight gain, high blood pressure, and brain fog from heavy metals and mold toxicity. Using functional and regenerative medicine, I healed myself and now share those tools with you. I earned my B.S. in Neurophysiology from Northwestern University, my M.D. from the University of Illinois College of Medicine, did my internal medicine residency at Northwestern, and specialized in gastroenterology at Chicago Medical School. I'm also certified in medical acupuncture from UCLA and 5X board-certified in functional medicine, anti-aging and regenerative medicine, gastroenterology, obesity medicine, and internal medicine. This lets me blend the best of traditional care with cutting-edge therapies like peptides, PRP, exosomes, and personalized plans. At The Real Gut Doctor, my focus is you: We create custom diets, supplements, and lifestyle tweaks to restore your vitality, mental sharpness, and joy. Whether it's beating IBS, colitis, or low energy, I've guided countless patients to ditch meds, heal after surgery, and live fuller lives. No extreme diets or guesswork—just real results.

Dr. Shiv Goel, MD is a board-certified physician and the founder of Prime Vitality Care, a physician-led functional medicine and wellness clinic based in San Antonio, Texas, with telehealth services available to patients in all 50 states. Dr. Goel trained in internal medicine and functional and integrative medicine, and has spent his career building a practice model that treats the root causes of poor health rather than managing symptoms in isolation. His clinical philosophy is grounded in the understanding that hormones, metabolism, inflammation, gut health, and mental well-being are deeply interconnected systems — and that lasting health improvements require addressing all of them together. Prime Vitality Care specializes in physician-supervised GLP-1 medical weight loss programs using semaglutide and tirzepatide, bioidentical hormone replacement therapy (BHRT) for women, testosterone replacement therapy (TRT) for men, peptide therapy including Sermorelin, BPC-157, and PT-141, and comprehensive functional medicine consultations for patients with chronic fatigue, gut dysfunction, autoimmune concerns, and metabolic disease. Dr. Goel is a sought-after expert on the clinical application of GLP-1 therapies, the role of hormonal imbalance in weight resistance, and the future of physician-led telehealth medicine. He speaks regularly to the gap between what conventional medicine offers patients with metabolic dysfunction and what a root-cause, functional approach can deliver when the right diagnostics and time are applied. Through Prime Vitality Care's HIPAA-compliant telehealth platform, Dr. Goel brings the same standard of clinical depth and personalization to patients nationwide that San Antonio patients have relied on in person — with lab coordination through local Quest Diagnostics or CPL sites and all prescriptions compounded and shipped directly to patients.

Through Premier IFM, Dr. Mortensen has helped more than 5,000 patients and is known for translating complex medical research into practical, evidence-based recommendations for both patients and the media.
