There is much more background info on Longo and his work on intermittent fasting if you go digging. More interesting than this particular piece, which is very short on context and science relating to the study of intermittent fasting, calorie restriction as adjuvant cancer therapy, immune regeneration via fasting, etc. http://gero.usc.edu/faculty/longo/ http://www.eurekalert.org/pub_releases/2014-06/uosc-fts06021...…

Do any of these reveal the diet basics? I wonder if a Soylent-like product could deliver?

There are a few ketogenic soylents -- check out the sidebar at http://www.reddit.com/r/soylent/

Actually, not eating for an extended period does have one very significant effect. It radically changes the makeup of your microbiome. I suspect that people who experience health benefits from "detoxes" typically suffer from dysbiosis, and by restricting food supply they essentially hit the "reset" button on their gut bacterial populations.

...and then the bacteria reverts to previous within a few days of returning to the previous diet. Gut bacteria adapts really rapidly to whatever you're eating, whether you do a "reset" in between or not.

Well, probably, but that is not absolutely certain. Sometimes, after a forest fire, the types of trees that end up dominating are different from the trees that dominated before the fire.

This study is definitely leading up to an FDA (they hope) approved, marketable diet. The actual study does give some hints at what the diet is comprised of, "to last 5 days every month and to provide between 34% and 54% of the normal caloric intake with a composition of at least 9%–10% proteins, 34%–47% carbohydrates, and 44%–56% fat". ... but reading further one finds this section: "Human Diet The human fasting mimicking diet (FMD) program is a plant-based diet program designed to attain fasting-like effects while providing micronutrient nourishment (vitamins, minerals, etc.) and minimize the burden of fasting.

Forgot to add the link. Sorry.

Here is the full text of their pseudo-scientific research: http://bit.ly/1MRWyhv

I used bitly.com to shorten this link, and it takes you to a page that begins to download the pdf file associated.

I think clearing out your bowels would be considered de-toxifying. As, much of that stuff just stays inside your intestines unless you do some kind of colon cleanse (men should do this with their doctor at 40-50; depending on how much red meat they eat). Also, with fat being burned and toxins are mostly stored in the fat, I have a difficult time understanding how losing fat isn't detoxing. I meant to say it's painful…

Detoxification is a myth: http://www.theguardian.com/lifeandstyle/2014/dec/05/detox-my... There is no science behind it. There is also no science behind extended fasting, giving your body a "break" from digesting and so forth. By all means fast if you feel like it and you believe there is some health benefit - you are harming no one, after all - but please don't try to justify it with medical science.

I find it strange that you picked a newspaper article with interviews and I posted an academic article filled with scientific citations. Maybe your ingrained belief feels validated with a newspaper article but I'd hope you'd have some scientific rigor and look at actual studies.

I currently intermittent fast by skipping breakfast + lunch, partially because I'm lazy, partially because it allows me to easily eat 'all my calories' in the end of the day. I really like this as it provides a 'buffer' for unexpected food, such as random cake, or random lunches with colleagues etc. Has anyone here actually ever TRIED fasting a full 24h day? I have. I HATED it. Well, the fasting itself wasn't that ba…

>Has anyone here actually ever TRIED fasting a full 24h day? I have. I HATED it. Well, the fasting itself wasn't that bad, however, the next day my body went FULL berserk mode and I literally couldn't stop myself from eating. It was really weird and I never had such strong biological urges. That's when I decided I'd just stick to fasting until 5 pm when I eat diner.

Yeah, Yom Kippur fucking sucks. Every damn year.

Which specific "toxins" are in your fat? If your colon isn't working properly you are very sick and you need a doctor ASAP not a fast. The fact fasting (perhaps) has benefits has absolutely nothing to do with "toxins."

And what are the LD50's of those "toxins"? This is my first question to people who go on about "toxins" and "detox" and "cleansing". I don't want an exact number, just a ballpark. Is it micrograms, milligrams or grams per kg body mass? Surely these people who know so very much about "toxins" must know the one fact that distinguishes the things we informally call toxic from the ones we don't. It would be the hieght of…

"Toxins" could be a poor word choice on my part. But our body can be slowed down with the modern food we eat, the poor environments we live in, and genetic predisposition. I think fasting is a way to remove road blocks in our body, for whatever reason they appeared.

But to be clear, I think a lifestyle of eating fruits and veggies is more effective than fasts, when trying to achieve this.

There are a lot of medical, yes scientific, benefits to fasting. At the end of the day, it helps the body out (strengthens immune system), among other ways, whereas it might be struggling with eating regularly. Also, most research would never encourage people to go without eating more than seven days, as that's starvation mode and the Hippocratic oath has some things to say about that.

Your body is digesting food that remained in your intestines and also fat deposits. Toxins are in the fat and removing undigested food can have a liberating affect.

Undigested food does not stay in your intestines and neither does any toxins. Can you name any of the toxins?

'Toxins' could be a poor word choice on my part. There are things, within fat, that disrupt our body's ability to function. It could just be 'its bad fat' that was ingested by a poor diet.
