Hi, I'm Holly Heartz

Registered Dietitian and Sports Nutritionist based in Fredericton, NB.

I have been counselling athletes from recreational to Olympic since 1998. I apply practical advice based on sound scientific principles to help people understand nutrition. My background is in exercise physiology and sport science, medical nutrition therapy, along with sport specific nutrition recommendations helps athletes attain their goals.

Holly Heartz, Nutritionist.

My personal interest in nutrition was initiated during my teens with a desire to fit in with the body norms observed in my peers. I was always trying to "slim down". Exercise wasn't cutting it and I didn't have a firm understanding how food could help. This frustration sparked my desire to further my understanding.

Years later, I continue to be as active as possible and eat foods for their nutritional components...not just to attain the body I desire. I see many athletic and non-athletic women who fall into the same category of desiring a specific body and not able to attain it. There are many other factors around metabolism, genetics, stress, and just living life that need to be addressed. I can help in this understanding for the individual seeking more knowledge.

My Nutrition Philosophy

Eating well is more than making the most nutritious food choices.  It's about nourishing your body and your life. It's about having a healthy relationship with food and creating habits that are sustainable for life. I can help you sift through the barrage of food and nutrition messages and work with your lifestyle to help you meet your goals.  Eating well is different for everyone and your individuality is considered.


I use a functional nutrition and integrative approach: looking at how the body works right down to the cellular and genetic level.  All recommendations are based on scientific evidence.


Food and nutrition is used to maximize your health and performance.  For athletes and active individuals, this includes I consider your nutrition and performance goals. Your nutrition plan should be personalized and consider your health and well-being. 

Meals and snacks that are enjoyable and fuel the body are important in meeting this goal. Restriction and labeling food good or bad are not part of my process and is not necessary. Continuing a good relationship with food is of utmost importance.

“A proper diet cannot make an average athlete elite, but a poor diet can make an elite athlete average.”
