Cosme Rubalcaba, RD, CT | Dietitian

About Cosme Rubalcaba

I’m Cosme Rubalcaba, a Registered Dietitian Nutritionist (RDN, LD) with dual master’s degrees in Dietetics and Health Sciences. Over the years, I’ve worked everywhere from hospitals and critical care units to community health programs helping people of all ages improve their nutrition, manage health conditions, and reach their goals. This wide range of experience allows me to offer a unique blend of science-based expertise and real-world strategies that fit into everyday life. My philosophy is simple: when it comes to our diets, we should never feel overwhelmed or uncertain when trying to make good conscious decisions. I don’t believe in fad diets or one-size-fits-all approaches. Instead, I create personalized approaches tailored to each client’s needs, lifestyle, and goals whether that means weight management, increasing muscle mass, navigating through serious medical conditions, or simply learning how to eat in a way that feels good and sustainable. Outside of my professional work, I’m passionate about wellness, fitness, and living a plant-based lifestyle. I know firsthand how busy life can get, which is why I focus on making nutrition realistic, approachable, and doable for anyone. My clients can expect encouragement, accountability, and a true partner on their journey to better health. At the end of the day, my drive comes from seeing lives change. Helping someone feel stronger, healthier, and more confident is what motivates me every single day and I’m excited to help you take that next step forward.
