It's a very elegant, most likely conserved mechanism that may generalize to virtually all diseases of autoimmunity and not just multiple sclerosis. However, that obviously needs to be proven clinically before you can say that and it might take a while.
Also, the conversion of animal research to human has another challenge: rodents have a faster metabolism. To have any hope of recapitulating those type of effects, you really have to go a while without food.
There seems to be a more medically safe way of probably tapping into mostly identical effects though, which is a "fasting-mimicking diet." Ultra low calorie, fits a specific macronutrient profile.
