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.

Just for the record, skipping breakfast + lunch has nothing whatsoever to do with fasting. It's not even remotely similar in terms of how your body reacts to it. And as others have commented yes there are many of us who have fasted for days at a time for religious reasons.

Fasting means abstaining from food for a period of time. Breakfast is called breakfast because you fast while you sleep and break the fast with breakfast so break-fast. Sure a 24 hr fast isn't a multi day fast but that doesn't mean it isn't a fast. 24 hr fasts are a commom intermittent fasting schedule. Religious practices that are called fasting last less than several days. When my doctor wants me in the fasted state (bloodwork/surgery) they say no food for 8-12 hrs. Saying short fasts have "nothing to do with fasting" is totally untrue.

"Skipping breakfast and lunch" is a pretty reasonable way to summarize "intermittent fasting". I don't know how credible "IF" is scientifically, but lots of people use the word "fasting" to describe it.

What's the number of hours you're calling the threshold for "fasting"? I assume it's some high number, like 24-48 ("skipping breakfast and lunch" gets you past 16). Can you cite a source for the stark metabolic difference you're implying?

This has been known for a long time. The big question is whether this can actually work in humans. Rhesus Monkey's have shown some promising results, but the evidence is conflicting. I also wrote an article recently on this and other forms of lifespan extension: http://mitchkirby.com/2015/06/02/can-we-live-forever/

He said intermittent fasting. IF is basically what he described. 16 hours of no eating with an 8 hour window where you eat. I think some people take it farther--20 hours of fasting (water permitted) followed by caloric intake for four hours.

IF includes a lot of different eating schedules - Eating for 5 days a week and fasting for 2 is a common practice too. When I did IF I fasted every 4 days.

I recently did a 3-day fast. It wasn't too bad. I fact I thought I would be ravenously hungry at the end of the 72 hours but I just ate a normal meal and it was fine.

I can't say I felt any better after the fast. I had lost a few pounds but nothing else noticable.

One problem that people might have with fasting and then wanting to binge is that the starchy, sugary diet that the USDA and FDA have been promoting as "healthy" for the last four decades is actually the opposite. The food pyramid is pretty much upside-down. If your diet is mostly simple carbohydrates, they metabolize quickly and leave you hungry for more.

If you eat a diet richer in fats and proteins and leafy vegetables your appetite is slaked for a much longer time.

The idea that intermittent fasting is healthy makes sense to me. Prior to the last few hundred years, certainly prior to the last few thousand years, our hunter-gatherer ancestors probably routinely went without food for a few days at a time. Our metabolism would have evolved to operate optimally with that.

Ah, this gets me extremely suspicious until there's independent verification.

If it can't be independently verified, it can't be called science, no matter how promising the study is when they run it.

Inversely, if it can be independently verified, it can be called science, no matter how suspect they are.

>pure detox. Headaches, migraines, agitation, etc. Detox is a pseudo-science word anymore. Is that detox or just your blood sugar level going down?

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…

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."

I've been fasting one day a week (24h and recently closer to 36h) for a little over a year now. The first few times were hard to get through, and at first I experienced the next-day binge you describe. The worst part was having trouble sleeping through the second night of a longer fast. After a few repetitions I got used to it. I don't feel like stuffing myself the next day. The hunger during fasting is still there,…

Weirdly, after 24 hours, I am the opposite of ready to binge-eat. I feel hungry, but I'm also very quickly satiated.

The revelation for me was after my second accidental 24hr fast, before doing anything deliberate with my eating schedule. I had skipped lunch the previous day, and then household drama prevented me from eating dinner. The next day, we had a team dinner set up at Publican in Chicago, which is hugely a metric fuckload of calories, and so I skipped lunch that day as well.

I was pretty hungry when we got to the restaurant but found myself too full to eat pretty quickly, much more quickly than when I'd been eating on a more "normal" schedule.

I also find that on an IF-y schedule, I'm a little hungry at 2PM; I eat a couple eggs, and then I am basically never hungry at any other time. I still eat dinner, but mostly because we cook for the family.

A fringe benefit of this lightweight pseudo-fasting schedule is that it's very easy to control macronutrients. I haven't eaten in 18 hours, so I'm eating because I legitimately should be eating, and so almost anything works for me; I don't find it at all difficult to opt for proteins and fats over carbs, which is challenging on the "normal" schedule.

Basically: the "normal" eating schedule is, in my case, just dumb.

One year is a quite long period; do you see some noticable changes since you started to fast: wieght loss, more/less active, etc?

Detoxing from what? Personally, my liver and kidneys pretty well no matter what I am eating (or not).

I believe the idea is toxins do tend to get stored in fat, so when you are running on stored fat - you can release them. I can confirm you can have sudden ups and downs when fasting and I never experienced headaches until i started.

Which specific toxins are stored in fat?
