If you play sport or take part in some kind of sporting activity you probably do so because you enjoy being active, maybe your sport is your passion, your life purpose. But, in my experience, many recreational athletes don’t take their diet as seriously as they could. I have talked about this a lot on social media, but exercise needs fuel, for us humans that fuel is the Calories we get from food and beverages. If you take your sport or exercise performance even semi-seriously and you aren’t taking 24-hour energy balance (Calories in Calories out) into account you might be reducing your performance potential, not to mention harming your health. There isn't an evidence-based practitioner in the world who would say otherwise.
