If this is a real effect, I wonder how many calories a persona can eat and still get the fasting effect. I have a non-24 hour circadian rhythm (although some thing still seem synchronized to light), which causes all sorts of negative effects, and I have found that eating < about 1500 kcal in a day reliably causes a significant improvement in my functioning two days later. Normally eating between 1500 and 2000 kcal most days does not cause this improvement. I am curious if what I am seeing is the same effects as would be caused by this much lowerer calorie diet or if there are tiers of fasting with different effects. Also interesting is that I have had some severe digestive issues for years; antibiotics helped for a month or two and eating about 3000 kcal over five days has been just as helpful for a couple of weeks now and seems likely to be at least as effective as the antibiotics. However, one or two days of calorie restriction does not have that effect on me. If this fasting result holds for MS, the effect of fasting on gut bacteria could potentially be part of how it works.
