New Study on "Carbohydrate Ingestion on Exercise Metabolism and Physical Performance"

One question I would have is, whether it’s reducing EIH or being used as fuel what difference does that make to the end user? If having X amount of carbs per hour is optimal, the athlete shouldn’t care too much about why it’s working.

The practical difference is your X would be different. They are saying preventing EIH only requires 15-30g/h, with no further benefits for higher intakes. Whereas the “fueling” hypothesis says more carbs is better up to the limits of your digestive capacity eg 100g/h.
