At the end of the day I agree that it's pretty important to try things out for yourself and see how it goes - intermittent fasting is one of those things that's pretty easy/safe to do (and has shown some insane health, longevity, disease prevention/treatment results in the experimental research lately) - I will say that having never purposefully fasted before, the first couple days of 16:8 sucked but now is fine. I also agree that while research can point you towards general guidelines, personal factors will be an issue. For example, from SNP analysis I carry rs1695(A;G) which reacts poorly to supplemental vitamin E, rs1801282(C;G) which may metabolize saturated fats differently, rs1535(A;G) which is associated with decreased ALA->EPA conversion efficiency, etc. (Which isn't even addressing the lifestyle/epigenetic aspects that are even more importantly, but largely unexplored, harder to test for.)
