Our Health and Fitness Optimisation Packages Include
We optimise your health, fitness, and performance like never before
At Theorem Metabolic, we believe that achieving optimal health and peak performance isn’t about one-size-fits-all solutions. It’s about understanding your unique metabolic needs and tailoring your lifestyle, nutrition, and exercise accordingly.
Founded by Justin Johnson, a lifelong fitness enthusiast and natural bodybuilding competitor, Theorem Metabolic is born from decades of experience and a passion for helping individuals unlock their true potential. Justin’s journey, encompassing mountain biking, football, and competitive bodybuilding, has instilled a deep understanding of the intricate relationship between training, nutrition, and individual metabolic responses.
Unlike generic approaches that often fall short, Theorem Metabolic utilises state-of-the-art technology and AI-powered analysis to provide personalised insights. We go beyond basic measurements, incorporating metabolic testing, CGM monitoring, and medical-grade body composition analysis to uncover the secrets of your metabolism.
Our success stories speak for themselves. Take, for instance, hybrid athlete Lottie Lamb, who, despite already consuming a high-calorie diet, was unable to make progress. Through our comprehensive testing, we discovered she had an exceptionally high metabolism and suffered from exercise-induced hypoglycaemia. By adjusting her macros and increasing her calorie intake, we helped Lottie gain over 2 kilos of muscle mass, maintain her body fat percentage, and significantly increase her strength and endurance.
At Theorem Metabolic, we’re committed to empowering individuals to achieve their goals, whether they’re every day people striving for a healthier lifestyle or athletes aiming to reach peak performance. We believe everyone deserves a personalised approach that unlocks their unique metabolic potential.
