17 Jan 2020 --- Low-carbohydrate, high-fat diets (LCHF) like the ketogenic diet (keto) may help reduce an endurance athlete’s response to fatigue at a low intensity, but the hypothesis requires more research, according to a recent Kerry Health and Nutrition Institute (KHNI) report. “This hypothesis means that the athlete would be able to run for longer at a suboptimal pace, indicating a potential benefit to the endurance athlete,” Dr. Lisa Ryan, Registered Nutritionist and Scientific Advisor to the KHNI, tells NutritionInsight. The report comes as keto is rising in the trending diets list yet again, with Google’s “Year in Search” analysis placing it among the most popular diets of the past year.
