It seems like every day the newspapers print some rubbish about fitness or nutrition. The headline is more often than not scary and sensationalist. No surprises there then. I mean, the job of the press isn't to educate you (perhaps controversial nut unfortunately true) but to sell papers. Using click-bait headlines that evoke emotional responses from readers is the most tried and tested way of doing this.
If you are serious about your sport you have to get serious about your diet, not just counting Calories to keep the fat off but understanding the role of each macronutrient and how they benefit your performance, recovery and health. When it comes to sports nutrition the evidence is clear that carbohydrates are god (1). The ISSN recommend 3-5g/kg of body weight for moderately active exercises and 5-8 g/kg for elite level athletes (2) and, in some cases even higher (1,2). Although there is some sparse evidence to imply that a high fat low carb (HFLC) diet may benefit ultra-endurance athletes (9,10). The evidence in favour of HFLC isn’t great to be honest and trials done on cyclists showed that, at best, performance is unaffected and at worst it is negatively impacted. (3,4).
