The Atkins diet works for me. It is the exact opposite of the Swank/Ornish/ low saturated fat diets for MS and heart disease.
The link to MS is part of the insulin resistance/blood glucose theory and how many children and adults with very severe epilepsy have been able to live quite normal lives with a ketogenic diet - a diet very low in carbohydrates.
A ketogenic diet can make the brain work properly - but you need to know if this will work for you.
A good guideline is that if your cholesterol profile is perfect, then maybe the low fat approach will work.
If your cholesterol profile is like mine, very high triglycerides, low HDL (good cholesterl) moderately bad LDL and borderline diabetic blood glucose levels, then the low carbohydrate/gluten-free diet may work wonders.
The big questions are why do the high carb/low saturated fat diets work for MS?
Why do low carbohydrate diets also work for MS?
As usual, it's the old MS problem - it's idiosyncratic, many causes and many lesions and it's so frustrating. This is a complex disease and finding a pathway back to some sort of health is very, very difficult.
