It's not a fad, there is quite a wealth of research supporting it's efficacy[1][2][3]. That also doesn't mean you need to fast for 3 days straight to consider your fasting intermittent - you can go 16 hours without eating and still reap the benefits. Skip breakfast and concentrate your calories into lunch and dinner - now you are intermittent fasting. [1] http://easacademy.org/trainer-resources/article/intermittent..…

So it's good for losing weight. But not anything magic compared to simply eating less?

As opposed to over-eating resulting in a global epidemic of obesity? Which eating habits do you think are the biggest "experiment"?

There's a middle line between over-eating junk food and fasting!

I agree. And I think the vast majority of people overeat and don't realize it. I think the obesity rates reflect that.

Observe the conversations around these articles every time they pop up: people think it's unhealthy to go without calories for any amount of time. Where does that come from?

It's both.

IF forces you to schedule fewer times to eat, so you eat less. But there are changes to the body when calories are restricted for 16 hour more. Hormonal changes that don't manifest when the body has regular insulin injected into the blood stream.

It's both.

Do they literally mean zero intake of calories for 72 hours? That sounds like a long time. How do you prepare for that nutrition wise and mentally? People eat at night during the ramadan.

If you have regularly eaten well for some time before (i.e. no junk food but real food) you probably (?) have a sufficient store of nutrients to keep your system running for 72 hours. The important question to me: Does drinking coffee (black without sugar naturally) blow the supposedly positive effects of the fast?

>Does drinking coffee (black without sugar naturally) blow the supposedly positive effects of the fast?

I don't think so, but I'm not professional. The caloric content of black coffee is negligible.

It's not that hard. If you're going to do three days you might as well do a little longer. It takes around three days to switch to ketosis, after which hunger disappears. I did a week with just a sense of determination and knowledge of what to expect, and my relationship with food improved immensely.

It's even easier if you eat a ketogenic diet already.

Going most of the day without eating is hardly "very unpleasant", and a lot of people are happy to play with moderate subtractive means to possibly improve their health or sense or well being. It's a lot more appealing than pharmaceuticals, even if those are provided free.

If nothing else, the dread of doing a short fast is a pretty decent indicator that you should try it. Being tied to a strict eating schedule is awful.

This is all short term studies. I ate once a day for over a decade, it just means you eat a large meal. If anything stretching your stomach makes over eating easier as you get used to large meals so eating an extra one is easily adds an extra days food. Worse, you end up getting pushed to calorie dense food.

PS: My original thought was it would save a lot of time which it probably did.

It's being around for millennia for. And for millenia, many people thought the Earth was flat, the age of a belief doesn't validate that belief.

And dismiss things just because is against your own assumptions is also far older.
