So far I`ve searched all internet on cases with people who reversed grey hairs, most did it by fasting / keto
But I`m concerned about fasting , does it really cause telomers to grow / be more young ?
What's your opinion on this theory guys ? Is fasting REALLY that good ? Then why people who don't really eat that much are sick ?
Well, before you get too disappointed by the limits of fasting (inabilities to completely rejuvenate the human immune system within three days, or reverse gray hair) note some amazing benefits.
Animal and human fasting studies have shown strong and replicable effects on many, many health indicators. Greater insulin sensitivity, reduced blood pressure, lower body fat, reduced IGF-I, lower insulin, lower blood glucose, fewer evil atherogenic lipids, decreased chronic inflammation -- these are all solid, well-documented affects of "fasting" (IF and PF) to varying degrees.
Fasting (depending upon how you actually do it) can also help improve outcomes in cancer, myocardial infarction, diabetes, stroke, AD, and PD. It triggers adaptive cellular stress responses, which enhance our abilities to cope with stress and counteract diseases.
IF and PF may also may protect cells from DNA damage, suppress unwanted cell growth, enhance apoptosis of deranged cells, enable autophagy, prevent the formation and growth of several cancers....on and on with the potential benefits.
Put all that in a pill and swallow it, and you've got yourself genuine anti-aging hype.
And of course fasting is free of charge. So, um...it requires nearly nothing to practice -- just you and your levels of discipline and staggered time. And it can be fun! Challenge yourself with it. How far can you safely extend your little fasting trips, and where do you draw your own conclusion that enough's enough, or enough isn't enough and you can move even more deeply into the practice.
Researchers tend to wag a finger and snarl that undertaking "longer fasts" (e.g., >3/d) should be done in a clinical setting; no one wants you out there in the wild world getting dizzy, falling, and then suing the shit out of everyone because -- "Well: We Told You To Fast In A Clinic." In many cases I see the reason for caution and safety; but if you're generally healthy, strong, and aware of your body, I think it's worth exploring all on your own.
