 I work with elite athletes and we've recently done a bit of a study comparing elite athletes, elite runners that are training about ten times a week and we compared their response over an interval session, a high-intensity interval session with that of a recreational trained group of runners training for a marathon like around three times a week. What we found was that the elite runners, contrary to what we originally thought where we think that we burn a lot of carbohydrate at high exercise intensities and we burn fat when we're just sitting here, the elite runners actually wound up burning three times more fat to explain their performance relative to the recreationally trained athletes. The implications are, I guess, that we need to appreciate fat and fat burning as something that's valuable for exercise performance and then if we can confirm that finding, we probably need to have a closer look at how we can become better fat burners to support high-intensity exercise performance. Tweaking your diet, potentially reducing your carbohydrate content to up-regulate your fat burning ability might be something that we want to work on in the future. It's a hot topic, a controversial topic because there's some industry influence that's out there that perhaps our findings aren't that convenient with but that's, again, more scientists at the end of the day so the data shows what the data shows.
