Parris Strouthos is a Canadian fitness and nutrition coach who founded Truth Body Systems after years of group coaching and personal training that started when he was just 17. He holds a Bachelor of Science in Human Kinetics from the University of Guelph, along with certifications in Precision Nutrition and personal training.
His philosophy centers on a science-backed, personalized approach to body composition — cutting through the noise of fad diets and quick-fix marketing to help clients understand what actually drives results. He believes transformation is as much a psychological journey as a physical one, and builds his coaching around sustainable habits clients can genuinely stick with.
Parris also authored the "Truth Handbook," a guide to core nutritional principles for lasting lifestyle change.
