About Us

Combat Sports Dietitian.com is a team of Registered Dietitians founded by John Sassone M.S., R.D., C.S.S.D.; a published researcher, author and the only registered dietitian in the world who is also a Brazilian jiu jitsu black belt and former professional MMA fighter.

Fighting out of Huntington Beach as a bantamweight on the So Cal pro circuit, John recognized a need for sport specific evidence-based nutrition; he then completed a Master's of Science Degree in Nutrition with a focus on exercise physiology, graduating with a 4.0 GPA out of Cal State Long Beach.
