I'm a board-certified physician in both Emergency Medicine and Obesity Medicine, and founder of Highland Longevity, a concierge longevity clinic in Fort Worth, Texas. My perspective on metabolic health is shaped by both clinical expertise and personal experience. I lost 87 pounds using GLP-1 medications—but made the common mistake of losing significant muscle in the process. That experience drove me to redesign my entire approach: I subsequently lost an additional 17 pounds of pure fat while preserving lean tissue. This journey transformed how I practice medicine and gave me firsthand insight into the challenges my patients face. With over 6,000 clinical hours in emergency medicine, I've seen the downstream consequences of metabolic disease—and became convinced that the real opportunity lies in prevention and optimization, not just acute intervention. I founded Highland Longevity to bridge the gap between reactive sick care and proactive health optimization. My practice focuses on medical weight loss, hormone optimization, and advanced diagnostics including DEXA body composition analysis and VO2 max testing. I emphasize evidence-based, physician-guided protocols using only FDA-approved medications or properly compounded pharmaceuticals. I speak and write about the science of sustainable weight loss, muscle preservation during caloric deficit, GLP-1 medications, hormone optimization, and the metabolic adaptations that make weight management so challenging for most people. Expertise: Obesity Medicine, GLP-1 Therapy, Metabolic Health, Longevity Medicine, Hormone Optimization, Body Composition

Dr. Gagandeep Singh is a leading metabolic health physician from India, specialising in the reversal of Type 2 Diabetes, Hypertension, Obesity and PCOS. With over a decade of clinical experience and more than 1,000 patient transformations, he has helped thousands break free from lifelong medication dependence. He founded Redial Clinic in 2013, one of India’s first root-cause disease reversal centres. His philosophy is simple yet radical: instead of suppressing symptoms with medications, he focuses on restoring metabolic function through nutrition, movement, and behavioural science. His often-quoted line captures the essence of the clinic’s ethos: “We don’t manage illness. We reverse it — with science, soul, and zero fluff.” Dr. Singh’s approach is deeply shaped by his own personal journey—having reversed his own obesity through disciplined lifestyle changes. This experience fuels his mission to offer patients a kinder, more effective alternative to conventional chronic disease management. At Redial, he uses a structured, data-driven program combining dietary protocols, continuous supervision, exercise planning, and lifestyle redesign. His expertise includes Type 2 Diabetes Reversal, Hypertension Reduction, Insulin Resistance, PCOS & Hormonal Balance, and long-term healthspan optimisation. He is also a popular health educator across Instagram, YouTube, and LinkedIn, where he simplifies metabolic science into practical, actionable insights for the public and fellow clinicians. Dr. Singh continues to champion a movement that places lifestyle, not medication, at the centre of chronic disease care—helping Indians reclaim their health, autonomy, and long-term metabolic freedom.

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.
