The article explores how genetic differences influence individual responses to training and diet. Dr. Daniel Wallerstorfer, biotechnologist and founder of Novogenia, explains that standardized fitness and diet programs are often ineffective because they ignore genetic diversity. Genetic analyses can create personalized training and nutrition plans tailored to individual needs. Studies have identified 13 genes that directly affect training outcomes, including muscle growth, fat burning, and recovery. These insights could revolutionize sports medicine by promoting customized approaches that enhance efficiency and reduce injury risk.
