According to a study from researchers at the Australian Institute of Sport, a diet low on carbs and high on fats could adversely affect the efficiency of endurance athletes. The research — led by scientist Louise Burke — was published recently in academic journal PLOS One and reported by Outside, and if the findings sound familiar, it’s because Burke’s team reached the same conclusion in a separate study three years ago. For years, the health and fitness community has just been reticent to believe it.
That original study was entitled Supernova, so this time around, Burke dubbed her project Supernova 2. The research encourages a reexamination of the relationship between a ketogenic diet and long-distance exercise, particularly running. For almost three decades, the low-carb, high-fat keto diet (LCHF) has been relied on as a fat-burning catalyst. Supernova 2, like the original Supernova study, confirms this. When athletes consume a diet of 75 percent fat and less than 50 grams a day of carbohydrates (that’s essentially two bananas), they do burn fat at an accelerated rate.
