My Journey in Nutrition

Growing up, I knew I wanted to work in health care. As I began to understand the role of diet and lifestyle in preventing disease and optimizing well-being, I knew dietetics would be the perfect career path for me. 

After completing my education, I was fortunate to start my career working at a leading National Health Service hospital in London. I had the opportunity to learn from incredible experts in a range of clinical specialties, including cardiovascular disease and Type 2 diabetes. These noncommunicable diseases are driven by lifestyle factors such as poor diet and physical inactivity, which means they are largely preventable.

This experience helped me realize that my real passion is to help people prevent disease in the first place. So in 2015, I founded Marcela Nutrition with the goal of spreading knowledge about how you can take care of your health through a balanced diet. I offer consulting to individuals and businesses, host workshops and educational sessions, and write about health topics for different brands.

In addition to prevention, other specialties of mine include healthy aging and women’s health. I am particularly interested in digital technologies for improving access to health information and regularly work with companies on product development. I love collaborating with brands such as Flo so I can share evidence-based nutrition content that will reach and hopefully empower so many people all over the world. 

Fun Facts

When I am not working, I am usually hanging out with my family (I have two sons). I love doing Pilates and yoga and try to exercise as often as I can. I also enjoy going to the cinema, traveling, and cooking.
