The better we understand genotypes the more we can tailor training and nutrition plans to individuals. But genetic testing may not be the complete solution, just another piece of the puzzle falling into place, says John Berardi

simple genetic screening can tell you all kinds of important information about how your body works. This could be whether you are a hyper-responder to a certain exercise protocol, or whether you are a non-responder, so you won’t get any positive physiological response from doing it. It can also tell you whether you would benefit from following a high-fat diet with the associated positive body-composition changes and lower blood-lipid levels, or on the contrary, such a diet would send these markers through the roof. We are all different and respond differently to certain training programmes and dietary approaches, and it’s all down to our genes. The days of a one-size-fits-all approach for everyone are gone.
What genetic screening tells us is a whole bunch of information about what makes you, well, you. This may well help the fitness industry shape specific training, nutrition and supplementation protocols that will specifically work for you. But will such testing be the silver bullet that ensures fast-track results for everybody? I don’t think so, but it will be used in conjunction with blood work, body-fat measurements and a host of other tests to better inform us about how you can get the best results possible in the most efficient way.
