Kyle Byron

Nutrition Coach,
BSc Nutrition, Pn2


Weight loss
Muscle gain
Sports nutrition
Feeding children


Professionally, since 2006 I’ve conducted about 16,000 nutrition counselling sessions (about 2800 clients). I’ve got a BSc in Nutrition, and have worked in hospitals, clinics, and in fitness centres. I was a Personal Trainer for 10 years. Personally, I’m a dad, husband, and way back in the day I’ve played rugby, football, and competed in Jiu-Jitsu at 175 lbs and 195 lbs. Few in the business can match my experience.


I eat healthy about 80% of the time, and exercise regularly. But there was a time when I was completely lost and unhealthy. So maybe I’ve been through something like you’re going through.

Kalliopi Kyrani

Registered Dietitian
BSc Nutrition, Masters Health Science


Weight Loss
Body Composition
Chronic Disease


Kalliopi is all about the Mediterranean lifestyle of eating fresh and local food, staying active, and family dinners. As a child, she was an athlete and discovered her love for collaboration and team success. She is naturally empathetic, making her a true coach.

She moved to Toronto from Greece when she was 18, without knowing anyone and only being able to speak very basic English. She persevered and can relate to others who are struggling with change and adapting to new lives.

Moving here caused an accidental dietary experiment (more processed food) and she suddenly valued her Mediterranean diet even more than ever.

John Gray

Registered Kinesiologist, Personal Trainer


Injury Rehab
Strength Training
Functional Training
All Ages


John is locally known as “Personal Training Royalty” because he’s been around so long (over 25 years) and is so great at what he does. John works with everyday people and elite athletes, helping them return to activity after surgery or helping athletes break through plateaus and compete on the world stage. John helped Kyle heal when many others could not, and as a result, John has helped many of Kyle’s friends and clients. John has a keen eye to spot movement dysfunction (which will stop healing if not corrected). And John can prescribe the right movements, intensity, and frequency of exercise. John makes house calls and works out of various clinics and gyms in the GTA.

If you want to hear about research, John can talk about that. Or he can simply say, “Do this, instead of that”.

Book a house call, free discovery call, or contact us with any questions!

Renita Lam

Registered Dietitian


Weight loss
Digestive, Gut, IBS, etc.
Eating disorders


** Currently on Maternity Leave**

Renita got into nutrition counselling for two main reasons: 1) to help others eat foods that they love while ALSO receiving proper nutrition for their goals; and 2) to have a socially acceptable reason to think and talk about food all day.


No matter where you are starting out, whether you are a high performance athlete or a busy parent with no idea what to make for dinner, Renita will meet you at that level and advance your nutrition.

Renita has worked in a variety of settings including private practice, medical clinics, fitness centres, and she teaches at U of T. Please see the testimonial below and her full bio to learn more about Renita.

Client Testimonial:

Renita is amazing. It took a lot for me to convince myself to start this process, and she set me at ease immediately. I noticed that she was quick to catch on to what made me tick, and crafted our meetings around that. I loved that she always asked if there were specific topics that I wanted to cover; ensuring that I got the most out of our meetings. I came out of my six-month program with new knowledge and motivation to keep my nutrition on track, and a year later I still feel her support when I am making food choices. Hire her! You won’t regret it!
