I tried the fast mimicking diet based on Longo's research and I spent the money to buy the 5 day kit from Prolon (company based on the research but longo does not benefit monetarily from it). It was not too difficult and I liked 'eating' a bit throughout the fast. I left the last 2 days for the weekend because I thought I'd want rest but in fact that was harder. Next time I'll arrange to do it while working, etc instead of on a weekend when I'd prefer to be enjoying! However, the first day was worst for me, as I got a migraine (probably from caffeine withdrawal) and could not have worked that day. So, I'd rearrange the order really.
The food is good and generally fits in with OMS except I believe the nut bars contain some coconut. However, summing up all the saturated fat the food provided per day was definitely under 10 grams, so I had no problem with that, and it's all plant-based anyway.
Overall I was fine while on the fast and not too tired. I believe it overall helped my digestion afterwards, as it is now much healthier and more regular. I think that shows it aided my gut health, which has been shown to possibly be beneficial for ms. Also, I believe the research and hope that it can help to reset my cells/immune system with more fasts in time. So, I'm open to doing it again, probably only 3-4 times per year though.
If you're new to the OMS program, healthy whole foods eating and such, I'd just stick to that for now. However, if you're feeling good with the diet
and open to fasting, it may be a good option. Read the research (and longo on YouTube interviews) and see how it goes. Feel free to shoot me any questions!
