Dr. Delali Hevi, MD, DABOM
Dr. Delali Hevi is a renowned expert in weight loss medicine, a double Board-Certified physician in Internal Medicine and Obesity Medicine, and a Certified Health and Wellness Coach. But what truly sets him apart isn’t just his impressive credentials — it’s his story.
Before he helped thousands of people lose weight, Dr. Hevi walked that very path himself. He knows firsthand what it’s like to struggle with weight and the emotional toll it can take. That personal journey fuels his passion and empathy — and it’s why patients feel seen, heard, and truly supported in his care.
Since 2001, Dr. Hevi has been guiding people toward lasting weight loss. In 2012, he made it his professional mission after earning certification from the American Board of Obesity Medicine. His approach goes beyond diets and scales — he helps patients uncover and address the root causes behind their weight challenges, whether it’s hormonal imbalance, emotional eating, gut dysfunction, metabolic resistance, or a host of other factors that are often unrecognised as causes of weight loss resistance.
What makes Dr. Hevi’s program unique is his ability to blend the best of both worlds: conventional medicine and science-backed holistic strategies. From prescriptions to personalized nutrition plans, from stress management to advanced body composition analysis — every treatment is tailored, comprehensive, and compassionate.
He’s not just a doctor — he’s your coach, your guide, and your biggest supporter.
Dr. Hevi has shared his expertise at international medical conferences and is an active member of multiple leading professional organizations, including:
- The Obesity Medicine Association (formerly American Society of Bariatric Physicians)
- The American College of Physicians
- The Obesity Action Coalition
Whether you’re just starting your weight loss journey or you’ve tried everything and nothing has worked — Dr. Hevi is here to help you write a new chapter.
