Gastroenterologist at The Real Gut Doctor
Hi, I'm Dr. Jeffrey Mark, M.D., a gastroenterologist and functional medicine expert with over 30 years helping people just like you get back to feeling their best. 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. If you're tired of feeling off and ready for change, let's chat. Visit therealgutdoctor.com or book a discovery call—I'm here to empower you every step of the way!

Registered Dietitian, Founder at PERFORMANCERX NUTRITION & FITNESS
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.

Publishers can leverage insights from macronutrient balancing experts to create compelling, science-based content that resonates with health-conscious readers. Expert quotes can add credibility to articles on topics like weight management, sports nutrition, and personalized diet plans. These insights can help explain complex nutritional concepts in accessible terms, provide practical tips for balanced eating, and offer commentary on the latest research in nutritional science. By incorporating expert knowledge, publishers can produce more engaging and authoritative content on nutrition and health topics.
Macronutrient balancing is the practice of optimizing the ratio of carbohydrates, proteins, and fats in your diet to support overall health and fitness goals. It's important because each macronutrient plays a crucial role in bodily functions. Properly balanced macronutrients can enhance energy levels, support muscle growth and repair, regulate hormones, and improve metabolic health. The ideal balance varies based on individual factors such as age, activity level, and health conditions, making expert guidance valuable for tailoring nutrition plans.
Nutrition experts specializing in macronutrient balancing can significantly boost their visibility and credibility by being listed in a specialized directory. It provides exposure to publishers seeking expert quotes for articles, potentially leading to media features and increased recognition in the field. This exposure can attract new clients, speaking opportunities, and collaborations with other professionals. Additionally, being part of a curated list of experts can enhance an expert's authority in the niche of macronutrient balancing and nutritional science.
A macronutrient balancing directory typically includes a diverse range of nutrition and health professionals. This may encompass registered dietitians, nutritionists, sports nutritionists, and functional medicine practitioners who specialize in macronutrient optimization. It might also feature researchers studying the effects of macronutrient ratios on health outcomes, fitness trainers with nutrition certifications, and authors of books on balanced eating. Some directories may include chefs specializing in macro-balanced meal preparation or wellness coaches focusing on nutritional balance for overall health.
