"long fasts can lead to muscle loss and impaired immune function" http://livinlavidalowcarb.com/blog/paul-jaminets-response-to-the-critics-of-his-safe-starches-concept/11920 (http://livinlavidalowcarb.com/blog/paul-jaminets-response-to-the-critics-of-his-safe-starches-concept/11920)One can reportedly get the benefits of fasting without going to such damaging extremes:
"Fasting, by inducing resource scarcity, promotes autophagy. Scarcity of amino acids, which can be achieved by a protein restricted diet, also promotes autophagy. And ketosis, which is part of the metabolic profile of starvation, also promotes autophagy.For intermittent autophagy fasting I instead use liquids plus raw fats like centrifuged coconut oil, raw egg yolks, pastured butter, raw suet, or a combo. Medium chain fats reportedly most promote ketosis, which is why coconut fats tend to get recommended.
Note in my section heading the shared word: “intermittent.” We don’t want to sustain fasts or protein scarcity too long; that could create malnourishment and cause more harm than good. Permanent ketosis may promote fungal infections. The most helpful course is probably to follow these strategies intermittently:
Engage in daily intermittent fasting: eat only within a 6 to 8 hour window each day. Within the fasting period, eat some coconut oil or MCT oil to promote ketosis.
Eat high protein for a few weeks while engaging in resistance exercise to build muscle; then low protein for a few weeks." http://perfecthealthdiet.com/category/disease/cancer/ (http://perfecthealthdiet.com/category/disease/cancer/)
But the idea with intermittent fasting isn't to skip meals and starve yourself so as to limit your total calorie intake, but rather to defer a meal or three to get the physical benefits of fasting without the calorie deficit. For example, after you fast one day, eat double the next day to make up for it, or half-again as much the next two days, or whatever it takes to sate your hunger. If you're ravenous after a workout, eat. If you're suddenly hungry between meals, snack. Mental ClarityI'm glad you are done with fasting and feeling up to eating. If you are feeling well and your appetite invigorated, then presumably now is the time for feasting, hooray!

In our book we discuss the benefits of intermittent fasting – it promotes autophagy, which extends lifespan and protects us against bacteria and viruses – but we don’t discuss whether feasting has any merits.
While there has been no real scientific study of feasting (except in the context of every-other-day implementations of intermittent fasting), feasting has been a hot topic in the Paleo blogosphere lately:
Martin Berkhan’s Leangains approach features intermittent fasting punctuated by occasional feast days.
Matt Stone’s 180-Degree Health approach is based on periodic overfeeding.
Coincidentally, Chris Masterjohn today offers us a review of Tim Ferriss’s new book, The 4-Hour Body.
For weight loss, Ferriss recommends intermittent fasting and feasting:
His fat-loss regimen sticks to a five-rule “Slow-Carb Diet” six days a week, but on the seventh day he resteth. This is the day for “reverse Lent,” otherwise known as bingeing on whatever the heck you want. In fact, Ferriss considers overfeeding one day a week to be a critical component of his fat loss regimen because of its effects on metabolism-boosting hormones.
In this respect he seems to have come to conclusions similar to those of Ori Hofmekler of Warrior Diet fame, who advocates fasting in the day and overfeeding in the night, and Matt Stone, whose High-Everything Diet uses overfeeding as its very lifeblood.
Stone recently told Jimmy Moore that one of the issues he’s still trying to tweak with his diet is to get rid of the initial gain in weight. Tim Ferriss may have solved that problem with his version of overfeeding, as folks on his diet usually gain weight on overfeeding day but nevertheless experience a net loss of several pounds per week from the very beginning.
So add Ferris to the group of self-experimenters who find benefits from occasional feasting.
Chris also discusses protein restriction:
Ferriss notes that periodic fasting from protein induces a process called autophagy, wherein the cell cleans out its mishandled, degraded, and aggregated proteins that otherwise accumulate. This is consistent with my experience. I had developed a problem with small wart-like risings on my hands and fingers at one point. Complete fasting for two weeks helped somewhat, but going vegan for two weeks made them completely disappear. The problem has never come back, despite my regular sumptuous feasting on animal foods of all kinds.
Perhaps protein cycling provides an answer to the question I had raised in The Curious Case of Campbell’s Rats. Namely, is there an intermediate intake of protein that maximally protects against cancer, toxicity, and fatty liver under all conditions? Perhaps the answer is not an intermediate intake of protein, but a periodic cycling of protein intake.
We note in our book (and this blog post) that protein restriction, even if calories are not restricted at all, promotes autophagy and therefore intracellular immunity and longevity. So we’re happy to endorse protein restriction.
But high intake of protein, especially of ketogenic branched-chain amino acids like leucine, does promote muscle synthesis. So what is a bodybuilder or athlete, who seeks the greatest possible muscle growth, to do? Is there an inevitable conflict between athleticism and longevity?
It’s possible that protein cycling – say, a week of protein restriction followed by a week of high-protein intake – might help resolve the dilemma, providing 80% of the longevity and health benefits of protein restriction and 80% of the muscle synthesis benefits of high-protein diets.
If so, Art de Vany would not be surprised.

PaleoPhil, I am super grateful for your infos about fasting. Gave me new insights.
Aura, dry fasting is a VERY serious procedure. I did several three days, once 5 days and once 6 days full dry fast. That was the toughest one! Especially with my underweight (no fat at all).
But what you did had no sens at all! If one gets the problems like yours one must help his body to detox it means liquid as much as possible, better from all the ends :). You better water fast to eliminate by-products from yr body and then switch to revive yr micro-flora in the guts with all possible means.
The right fasting (water or even dry in exceptional case) is a powerful healer or let's say helper for yr body. The wrong one could be disaster! In this case PaleoPhil is right. Even more dangerous to be in the hand of "normal" doctors to brake the fasting!
Be careful next time, good luck and good recovery...
