For those taking a B-cell depletion medication such as Ocrevus, are they achieving better results in managing their MS symptoms and slowing progression by combining it with an intermittent-fasting (IF) dietary regiment?

It has been shown in studies that the microbiome (gut bacteria) is different compared to a normal individual for those patients diagnosed with MS. Can following an intermittent-fasting (IF) dietary regiment where an individual fasts three days per week combined with b-cell depletion such as Ocrevus slow progression of MS even further than b-cell depletion only.
