Thanks so much for showing an interest in Gazelle Nutrition! I am Ashley Leone, a Sports Dietitian and the Owner of Gazelle Nutrition. I provide nutrition advice and plans to athletes and everyday active people alike. My goal is to use my over 20 years of experience as a Registered Dietitian to help fuel your inner athlete and put good sense back into eating.

My previous work has included roles as a nutrition specialist and educator at St. Michael’s Hospital, The University of Toronto, Lucky Iron Fish, and at private clinics. I have also published studies on energy needs, body composition, and obesity.

At Gazelle Nutrition, I specialize in nutrition for endurance athletes, muscle gain, adolescent athletes and military duty. I also provide guidance for a range of other sports and consult for sports-related food companies. I offer both team and individual diet analysis and food and hydration planning around exercise. Finally, I believe that access to credible sports nutrition advice should be simple.  So, I offer science-backed blogs on my site, as well as links to other useful websites to help you determine your best nutrition strategy.

I look forward to helping you optimize your sports performance with nutrition.


Thanks for checking us out!
