Numerous things on MS being helped by changing to a low carb or even carnivore diet.

The ultimate elimination diet is a diet of beef and water only. If it were me knowing what I know today that is what I would do for a month. See if any symptoms improved. Nothing lost if no improvement other than not getting to eat some favorite foods for a little while. At the very least I would cut out the sugar and the vegetable oils. But that would be me based on what I have learned. Not medical advice for anyone, just my opinion.

I just did a YouTube search and came up with a lot of hits. Scan through them and see if any of them look interesting.
