Can Amyotrophic Lateral Sclerosis be Treated with Ketogenic Diets?

Ketogenic Diets have positive beneficial effects in many other neurodegenerative diseases, but only 2 failed clinical studies have been done on ALS. However, the pre-clinical ALS studies are excellent, so why do these studies fail? We need to have well-designed KD & ALS studies that use organic whole-foods based nutrition with healthy fats, instead of the adulterated and toxic diets/formulas used previously.
