Question on fasting

OK, fasting, pretty much by definition, is calorie restriction. Well, maybe not to people eating junk, who would just eat extra food on their non-fasting days, but…even that’s an extreme example.

So yeah, I most definitely did NOT change the subject.

And you’re right, there have been mixed results on calorie restriction studies. HOWEVER, you seemed to think that fasting is “automatically dangerous and bad and never in any way beneficial”, and I’d say the mixed results of those studies shows otherwise.

Yeah, you did, and you’re pretty obsessed with this false dichotomy of “people stuffing themselves full of junk all the time” and… well, whatever the hell you’re talking about. A division you created and keep using to justify your lack of any valid cites for the benefits of fasting.

Do continue any time you want to actually address the topic with something other than misdirection and anecdotal info. I’ll be ignoring you and the other woo-pitchers until then.

When you make a specific claim, as you did, and follow it with links to information related to that claim, those are called citations, and either they support what you said or they’re a misdirecting waste of time.

Calorie restriction and fasting are, for all practical purposes, the same. A Venn diagram of the two would overlap. Do you know what a Venn diagram is? Do you need a cite for that? Maybe you can find it on wikipedia, which is always an unbiased, complete source of info on controversial topics. :rolleyes:

I’d have to question that. In some cases, a significant enough change in degree means you have a different phenomena. For example, consider the difference between donating a pint of blood and donating ten pints of blood.

Kudos for putting your money where your mouth is, or something like that.

I’ve only had time to skim these, and unless I missed an exception, all of them deal with two topics: Alternate-day fasting for obese and morbidly obese subjects with heart issues, and the month of half-day fasting for Ramadan.

ADF is a one-day fast alternated with a normal (for certain values of normal) eating day, and these studies are of individuals who are caught between an urgent need to reduce body weight without undue cardiac stress. The studies are not of fasting, per se, but a calorie reduction plan that forces weight shedding without heart strain.

Ramadan fasting is not true fasting for most Muslims; they abstain for the daylight hours and then eat more or less normally at night, often with an extra meal very late. So it’s approximately 12 hours of fasting alternated with 12 hours of normal eating for a month.

These are rather specialized situations and I don’t see that they are representative of the more general sense of fasting for 2-3-7 days that most of the health claims are made for. It’s possible there’s linkage between these results and the longer term but I’d have to see studies that examine that linkage. Can you point to any that have studied fasting in a more conventional pattern?

Read this yesterday, started it today. A bit of a headache by sundown but no problem during the day - hopefully this will work, at least for a month (going to shoot for 30 days because why not).

Every time you sleep you’re fasting, most people are anyway. Ramadan fasting is one form along the continuum of fasting. You’ve already disparaged links to blogs as cites but tough luck here’s another one. Anyone reading the thread who has a genuine interest in fasting will find it helpful. I’ve been intermittent fasting for over a year and think it’s great. Fasting has been extensively studied in many forms, Brad Pilon’s book Eat Stop Eat has the most references of any work I’ve seen so far if you really want to see studies relating to the topic.

Another source I found very helpful in beginning fasting was Dr. John Berardi’s experience with them. That link is to the index and you can download the entire PDF. Again, I think it will be quite helpful for anyone interested in trying it.

Down 23 so far, I want to lose 30 more by April 15.

And in their defense, I should say that my friends are advocating this as an adjunct to, rather than a replacement for, the WW program. Kind of a JATO unit, so to speak.

I don’t recommend fasting for weight loss. You’re better off just permanently and gradually changing your eating habits. it’s not easy, but it’s better than yo-yoing up and down.

But I admit, it does work to take off weight quickly. A pound a day during the fast is common.

My ex-wife did several 20-day juice fasts, and lost around a pound a day. I did a couple myself, and had the same result.
