About Dr. B

Chaka Brittain

Your Partner in Sustainable Weight Management

Meet Dr. Chaka Brittain

Hi, I’m Dr. B, and I’m passionate about helping you achieve sustainable, long-lasting results in your weight management journey. As a board-certified nurse practitioner specializing in lifestyle and obesity medicine, I focus exclusively on weight management to provide the highest level of care and support for my clients. My sole purpose is to guide you through a personalized, comprehensive approach—one that empowers you to take control of your health and achieve your goals
with confidence.

With nearly 20 years in healthcare, including experience in oncology and palliative care, I’ve witnessed firsthand the devastating toll of preventable diseases. This experience fuels my commitment to helping people reclaim their health before it’s too late. Through tailored fitness plans, nutritional guidance, expert medical management, and health coaching, I address the root causes of obesity—whether it’s food addiction, binge eating, or healing an unhealthy relationship with food.

My Story: I’ve Been there Too

Like many of my clients, I know what it’s like to struggle with weight. After having two kids back-to-back, life, career, and family took priority—and my health took a backseat. Forty pounds later, I reached a breaking point. I invested in a personal trainer, transformed my habits, and reclaimed my health. That journey didn’t just change my body—it changed my life.

Now, I walk the walk, living a balanced lifestyle rooted in regular physical activity and whole-food, plant-based nutrition. My personal journey fuels my passion for helping others experience the same life-changing results.

Beyond the Clinic

When I’m not working with clients or teaching as an assistant professor of nursing, you’ll find me spending time with my husband and two kids. We love family cruises, lazy beach days, and planning our next adventure. Life is meant to be enjoyed, and I’m here to help you feel your best while living yours to the fullest.
