Just One Meal a Day Longevity Approach
I recently read an article in Life Extension Magazine, which mentioned, that in addition to a restricted diet as a means to increased longevity,
simply eating one large meal a day (with the daily caloric content not reduced) also seems to have a similar longevity effect. See also this mice
study at https://www.nia.nih.gov/news/longer-daily-fasting-times-impr...
My opinion as to why this one meal approach could possibly work is that it in line with paleolithic’s man eating habits over hundreds of thousands
of years of food consumption habits by our caveman ancestors. In such a scenario, when does not wake up and get breakfast, and then have lunch at
noon, followed by dinner at sunset. Instead, essentially a single large meal once, most likely, when available.
My question is: Can any biochemist explain to me why such a singular large meal approach could possibly impact longevity?
My speculation, possibly a lot of biochemistry and digestive related systems that have to be put in place to efficiently assimilate food. Eating three
times in larger amounts (other than simple snacking) is ‘not normal’ (in a paleolithic sense), and may actually be inherently disruptful and
stressful to the body. In essence, perhaps our body has been tuned to a daily single large meal over a large part of the evolutionary history of our
human ancestors.
The related opinion of the author of the mice study, cited above, to quote:
"Perhaps this extended daily fasting period enables repair and maintenance mechanisms that would be absent in a continuous exposure to food."
However, I respond to this likely true point by asking: Why so on the timing/frequency? Perhaps, I contend, it is conditioning.
Other ideas?
Caution: Before attempting a one meal approach, read this article which also discloses likely RISKS at https://www.medicalnewstoday.com/articles/320125.php .
This article also notes the following benefits, to quote:
"The studies done on intermittent fasting show the following benefits:
it may help lower blood sugar levels and reduce weight in people with type 2 diabetes
it may positively affect the eating and sleeping cycles of people who are obese and increase their lifespan
it may benefit the cardiac system and improve memory"
The above points imply to me not a generic benefit to all, but a selective longevity boost in reduced life span subgroups, connected, for example, to
those with heart related issues, diabetes and obesity. This would be at odds with the mice study (where I assume the lab mice are genetically
homogeneous).

Good post sir,
The merit with the one meal a day?
We will see, it does, however, mostly follow/reflect my normal diet. I do not expect an extended life from it.
I hope it will be a benefit for those who try.

Thanks.

While one may not expect benefits from normally good habits, like consuming pure water (avoiding chlorinated water exposed to copper plumbing,
chlorates, bromide and heavy metals, halogen rich organics, problematic organisms,.. ) and air (free from dust, allergens, transition metals salts,
microbes,....) likely tend to greatly lengthen our lives, nevertheless.
And, adding healthy foods to the list, with paths for there improved consumption, seems rational to me.

Interesting, I can't open the first link, they apparently changed the location. Do you have another link?
My first thought is that a one meal a day diet still gets your body in a "dormant" state most of the day, just like a low calorie diet does. When
cells are not doing anything they are also not killing themselves...

Interesting speculation, the dormant state hypothesis.
I learned recently that sugar is the superfood for cancer cells (per a discussion I recently have with a medical student working with my doctor), and
extended fasting (or reduced eating frequency) means that cancer cells are likely weakened (or starved out of existence).
I mention this as I also read in Life Extension magazine results from a study claiming that the drug Metformin together with over the counter herb
quercetin reportedly kills prostate cancer (confirmed here, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6213406/ ), and there is research ongoing in other cancer studies as well. I asked the med student
how this occurring, and was told that Metformin is extremely good at removing sugar from the blood!
Unfortunately, I was also told that drug Metformin can only be prescribed and taken safely if one's blood chemistry is off (like pre-diabetic ).

I'm not doubting these results, or well, I am... I just think they could be (in)valid. As this is usually never discussed, and I would be surprised if
they did now:
Did they control for the fact that the mice being fed once a day see less humans compared to the mice being fed more often? Mice are hunted animals
and show for example strong spikes in their cortisol level when a researcher opens the cage. Cortisol is known to shorten life. The mice used in
laboratory are not the nice and tame mice someone could have in house, they are not used to humans because the have to be handled like the rest:
solitary like the genetically modified strains without an immune.
I didn't read the whole article so I don't know, but if you are interested here is the original article (I already disliked it because of the
animations used... but you might not).

A quote from the mice study, as one of your comments relate to mice being less comparable to humans, a conclusion from a comparative cross species
work, to quote:
" A recent comparative analysis of these studies indicated that CR and its associated mechanisms are likely to be highly relevant to human health and
longevity (Mattison et al., 2017). "

I really don't care about "random statement"; published so it is true. It just doesn't work like that.
The article I just attached? Major flaw; check "EXPERIMENTAL MODEL AND SUBJECT DETAILS
Animals, Husbandry and Diets" Nothing is mentioned about how they actually feed the mice. They do actually state that the mice are raised solitary. So
a big guy in a white coat comes in your solitary life all the day, there is a guy coming in twice a day against a guy coming in once a day. There is a
reason they don't discuss this matter and that is because they can't pay for the automated systems that were designed to circumvent this problem.

Comments on diet at the beginning of the study (in SUMMARY), to quote:
"Here, we directly compare in mice the two diets used in the primate studies focusing on three paradigms: ad libitum (AL), 30% calorie restriction
(CR), and single-meal feeding (MF), which accounts for differences in energy density and caloric intake consumed by the AL mice. MF and CR regimes
enhanced longevity regardless of diet composition, which alone had no significant impact within feeding regimens. Like CR animals, MF mice ate
quickly, imposing periods of extended daily fasting on themselves that produced significant improvements in morbidity and mortality compared with AL."
My guess is that if stress per human exposure was a major factor, the ad libitum (AL) group would fare better (just give them a lot of food and let
them eat when and as much as they wanted, with limited human intervention).
However, this group have the most reduced life span.

Of course eating unlimited amounts of crappy food doesn't make mice fare better.... I would never think that scaring the shit out of a mouse or a
human once or twice a day would be worse than letting them have an Amercian diet.

I personally consume an educated diet (more details below), regardless of what country I find myself in.
I do find Indian cuisine rich in health promoting herbs (like tumeric), likewise for Thai.
I cook in coconut oil and avoid processed meats (nitrites and nitrates are reserved for radical rich chemistry outside of the human body, see http://www.mnwelldir.org/docs/misc/hidden_h.htm).
While olive oil is good at room temperature, strong heating produces some rather unhealthy breakdown products. I also recommend fresh olive oil (which
is much more powerful antioxidant than store brought, usually within 6 months of harvest) which is available (expensively via air) via Olive Oil Club
(not affiliated but an occasional customer).
Colorful fruits (like mangos) are a bonanza of powerful antioxidants (which are quenchers of REDOX reactions liberating radicals) and plain lemon
juice is rich in ascorbic and citric acid.
-----------------------------------------------------------
The cure for the American (or bad other) diets is, in my opinion, socialized medicine! The government will come to understand the cost of unhealthy
foods and remove them.

I was referring to the spice Tumeric!
To quote (see https://www.healthline.com/nutrition/top-10-evidence-based-h... ):
"Turmeric may be the most effective nutritional supplement in existence."

Eating one meal per day in a rat cage probably leads to lower ROS generation. The rats don't have anything to do, so their metabolism is more active
when they eat, and they go dormant for the rest of the day.
Now, if you put those mice in a situation where cats were chasing them around, the ones who eat only one meal a day will probably get eaten first. And
that's why I don't call it healthy.

The strongest arguments state that our sedentary lifestyle alters and suppresses many systems in our body that would be needed "in the wild" which in
turn has many consequences.

If glucose in our blood is the main culprit regarding cancer or longevity then there's the obvious limit how low we can go. The body has its own
regulatory mechanisms and try to ballance the glocose level in a given range.
As a sidenote: I also heard that lowering body temperature can lead to longer life. But here we also "hit the wall" with the body regulatory
mechanisms. It seems we are doomed. ![:(](./images/smilies/sad.gif)
Maybe, just maybe, if we were eating once a day our lunch naked then we'd have chance.

Thanks for the graphics! I'm about to get off my chair and cheer for my Cheerios!!
Unfortunately that would be disruptive to my sedimentary lifestyle, which to date nearly all of my healthcare practitioners seem to be perfectly
content with.
Does anyone else believe that there seems to be a prejudicial tendency to discount the origins of our human specie and, in so doing, be more approving
of an apparently biologically incongruous diet along with a sedimentary lifestyle, which appears to be obviously detrimental to our immediate health
and longevity?
Meanwhile, any recommendations for an online course on how to wrestle with a snake in the jungle?

A sedimentary lifestyle diet.
"Mud is a slurry of water and sediment dominated by clay and silt sized particles."
"The role of clays in human health has experienced a revival in interest due to advances in modern instrumentation [e.g., transmission electron
microscopes (TEM), field emission scanning electron microscopes (FESEM), atomic force microscopy (AFM), and secondary ion mass spectrometers (SIMS)],
that allow us to study surfaces of nano-scale minerals in situ within their natural environmental matrix."
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2904249/
Sedentary lifestyles in the news.
"Southern states often rate poorly in health statistics such as obesity, cardiovascular disease and diabetes, and experts point to factors including
poverty, poor diet, less access to health care, sedentary lifestyles and a tradition of fried foods. The study, Bornstein said, indicates that the
same states “that are disproportionately burdensome for public health are also burdensome for our military.”

Side note allegory
“A lot of reptiles are ambush predators,” keeper Alex Mitchell told IFLScience. “If they don't have to chase their prey they become sedentary
and quite prone to obesity.”

Thanks Morgan, so a sedimentary life style is truly mineral rich!
And as to a jungle survival tip, I am a bit unclear on your point, except perhaps, when wrestling a snake, not to feel sympathetic given that both of
us may likely have suffered the ills of a sedentary lifestyle (or is that sedimentary if we both eat mud?).
--------------------------------------------------------------------------------------------------------------------------
I do confess to employing a speak-to-text software, which does, at times, present some interesting results with words that sound similar.

Well it was just a tip when venturing into the jungle to wrestle snakes. The first order would be cognizant to not let them get the jump on you being
sedentary ambush hunters, camouflaged amongst the leaves and sedimentary soils.
It occurs that some sedentary snakes subscribe to a one meal, 180 day diet or biannual meal plan.
"4 months, while a long time to go without food for us, is not all that detrimental to a well established adult ball python."
Aside from geologists and geophagists who embrace sedimentary lifestyles, well meaning others do not.
