Carb storage for unsupported ultra races

And what about Hammer Nutrition’s perspective that sugar is a mistake? I am trying to undsrstand why the current movement is directed at glucose/fructose so heavily, it doesn’t make sense.

Also they have written regarding Perpetuem, “You also need protein in your fuel, as roughly 10% of your energy requirements need to be fulfilled from protein. If you don’t provide some protein in your fuel mix, your body will be forced to cannibalize the lean muscle tissue to obtain the amino acids from protein to satisfy that approximately 10% of its energy requirements. That will increase the amount of fatigue-causing ammonia to be produced and allowed to accumulate in the blood and muscles… this is something to be avoided at all costs. The fat component in Perpetuem helps to stave off hunger pangs, while also serving as a “cue” of sorts to help the body access and use the vast amount of calories from fatty acid stores more efficiently.”
