Hi, I'm Holly Heartz

Registered Dietitian and Sports Nutritionist based in Fredericton, NB.

As a sports nutritionist, I have been counseling athletes of all levels, for over 2 decades. I specialize in applying sound scientific principles to create personalized sport-specific nutrition recommendations, helping athletes attain their goals. With a background in exercise physiology and sport science, I understand the specific dietary needs of athletes at all levels, from recreational to Olympic. Whether you are looking to enhance your performance, lose weight, or gain muscle, I provide the practical advice and support you need to succeed.

I believe that everyone can benefit from a better understanding of nutrition and that it should be accessible to all.

Holly Heartz, Nutritionist.

My fascination with nutrition began during my teenage years, driven by a desire to conform to the societal body norms observed in the media and among my peers.  Consistently aiming to "slim down", I found exercise insufficient and I lacked a comprehensive understanding of the role of food. This fueled my pursuit of extensive nutritional insights.

Now, after years of learning and personal development, I am committed to an active lifestyle and prioritize food choices based on their nutritional value rather than solely on body image ideals.  I have observed numerous individuals - athletic and non-athletic - facing similar challenges in achieving their desired physique.  Transforming body weight involves multifaceted factors beyond calories or exercise, encompassing an individual's metabolism, genetics, stress, sleep, gut microbiome, and more.  I  specialize in guiding individuals seeking comprehensive knowledge in navigating these complexities.

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.”
