I can't find the study right now, but from what I understand it is only really beneficial to animals the size of a mice, as soon as you move to bigger animals the effect is sharply reduced, and experiments with monkeys (or was it even primates? I don't remember) didn't find any real life prolonging effect. So you might be subjecting yourself to not enjoying food for no real benefit after all.

The article discusses studies with Rhesus monkeys that largely confirmed the results of the mice studies, and also mentions a study with humans (https://en.wikipedia.org/wiki/CALERIE) and some early, positive results.

I recall watching a video of an engineer practicing CR. He looked miserable and older than his years. He was constantly cold and had chronic sore feet because the soles of his feet were too thin.

When I don't eat enough, I don't get hungry, and I don't loose much weight, but I do have trouble sleeping which results in daytime fatigue and depression. For me the happiness/sleep threshold is sharp, so I eat just above that threshold.

I'm not sure if you skip breakfast, but if you do, you are missing a strong signal to your circadian rhythm. What happens is you end up sleeping later and waking up later as the rhythm shifts towards your first meal of the day.

[oh_sigh]

Do you have any source of proof of any of this? I have no problem waking up at 630am after 7 hours of sleep and not eating anything until after noon.

Thinking to premodern humans, do you think they would frequently have food waiting for them as soon as they awoke? Some days maybe, but then other days probably not.

[vlasev]

Hmm. If food is not waiting for you when you wake up, then you should sleep some more!

Not surprisingly, I don't have proof of what I said, but I've read in articles and studies that breakfast (and meals in general) tend to anchor your circadian rhythms (Although, light is a stronger signal). I might have extrapolated from reading about fixing your rhythms after experiencing jet lag and also from my own experience.

[pivo]

I'm the same as you. I don't eat until noon and can't make myself sleep past 6 am.

> Do you have any source of proof of any of this?

Of course not. There's never been any significant evidence of health benefits from breakfast.

[sudojudo]

Why the snark? No need for that. There are many studies that show a link between meals, especially breakfast, and our circadian clocks.

Here's a HN discussion regarding a Harvard study on the subject, from 7 years ago: https://news.ycombinator.com/item?id=199394

Please provide some evidence that these studies are insignificant and incorrect.

[dpark]

Because people have claimed for decades that breakfast is the most important meal and that you have to eat breakfast and made all sorts of unfounded claims with no evidence.

I have no trouble believing that breakfast is relevant to circadian rhythms. This is far different from saying that skipping breakfast inevitably results in "sleeping later and waking up later as the rhythm shifts towards your first meal of the day." This is a very strong claim that demands strong evidence. Some studies linking circadian rhythm to meals is not sufficient.

[discreteevent]

Firstly, you weren't asked the question. Secondly, you don't answer it. Proof was asked for yet you confidently come in with "Of course not" and no evidence or proof, for or against.

[dpark]

This is a public discussion forum. You can criticize my response. You cannot criticize me for responding. I certainly didn't ask for you to respond to me, and yet you did, which is perfectly appropriate.

[quickben]

Interesting. How much time after wakeup should the breakfast be? I'm usually 1-2 hours after, and I find that I tend to wake up later and later.

[skewart]

Did you read the article? It specifically mentions studies with rhesus monkeys.

[rubicon33]

I would be interested in reading that study if you could find it.

[coldtea]

TFA actually talks about possitive experiments with monkeys.
