Antonio "Tony" Castillo, performance through nutrition coach

Antonio “Tony” Castillo

Tony graduated from Florida International University in Miami with a B.S. in Biology, B.A. in Chemistry, and an M.S. in Nutrition and Dietetics. He is credentialed by the Academy of Nutrition and Dietetics as a Registered Dietitian. Having parents from the Dominican Republic, Antonio is fluent in both English and Spanish.

Enhancing performance through nutrition every day

Tony’s journey began as an overweight middle schooler. This continued throughout high school until he decided to jump on a “diet.” Unfortunately, this resulted in unsustainable weight loss. His weight fluctuated in college due to lack of nutrition knowledge, but this inspired him to understand how nutrition played a role in the human body.

Tony’s passion today is to teach others how healthy lifestyle modifications optimize performance in ALL areas of life. After working at the University of Florida and then with the Toronto Blue Jays, Tony focuses on helping you to become an elite performer. Being an elite performer in your field can take many forms, whether you’re the owner of an investment firm or a professional athlete trying to become an MVP. Tony’s plan is to teach his clients how to sustain their weight goals without counting calories or macros.

Nathan “Nate” Diaz

 

Nate graduated from the University of Central Florida with a B.S. in Biology. After college, Nate hired a physique coach to help him prepare for an upcoming summer show. His coach said, “In order for you to be successful in this sport, you have to ruin your relationship to food.” Months of restrictive meal plans and countless hours in the gym left Nate feeling stuck. He was fed up and decided there had to be a better, more sustainable way to lose weight. Becoming an expert in the field was the next step, so he attended Florida International University and received an M.S. in Dietetics and Nutrition. He also completed his dietetic internship at the University of Florida (yes, he interned with Tony), which allowed him to work as a fueling specialist with some of the nation’s elite athletes.

Performance through nutrition works!

As a credentialed dietitian through the Academy of Nutrition and Dietetics, Nate helps busy professionals optimize their health and performance by focusing on nutrition habits, sleep quality, and stress-management. He believes in a flexible approach to nutrition, free of cookie-cutter meal plans and restrictive dieting. In addition, he teaches culinary skills and provides easy meal prep recipes that keep his clients in the kitchen cooking delicious and nutritious food.
