Fasting vs. Optimal BMI For Longevity

[Anonymous No.12656663]

While there has been a lot of recent research in fasting/caloric restriction's impact on longevity, this new study just came out that confirms some older data that a slightly higher BMI---even going into the overweight range---may increase lifespan:

https://www.sciencedaily.com/releases/2021/02/210202085451.htm
>People who start adulthood with a body mass index (BMI) in the normal range and move later in life to being overweight - but never obese - tend to live the longest, a new study suggests. Adults in this category lived longer than even those whose BMI stayed in the normal range throughout their life. Those who started adulthood as obese and continued to add weight had the highest mortality rate.

Thoughts on this? Should I continue to do intermittent fasting? Or should I gradually add on some pounds to get into the group with the longest lifespan from this study? While many animal studies have connected caloric restriction to a longer lifespan, this has yet to be confirmed in a human student.

this sounds more like a corelation to lifestyle than a direct result of the bmi

not as nice as it sounds.
What's happening is that during the final years you go thru sicknesses, don't eat well, so you lose weight during them.
At that point getting too skinny will eventually kill you.
If you start overweight, you have more spare fat at the beginning of the downhill. Adds a few months/years to the average lifespan, but before that your life isn't any better than the normal-weights, you just manage a longer chronic phase of lying&dying in a hospital bed.

Obesity isn't from overeating, it's fat tissue swelling from excess salt, you can't cure it by jyst eating less. Since it's likely better to be mildly obese than starving, people who eat despite being overweight fare better healthwise than those who starve themselves to "healthy" weight. ("normal weight metabolically obese")

Are you later in life? As >>12656752 said, it may be good to have a little bit extra since most diseases result in wasting later in life, but unless you're at least in your 50's (maybe even 60's), I don't see any reason to intentionally become overweight. I'll also add that muscle loss begins much earlier, like in your 30's. Simply trying to be physically active and retain your muscle mass into older age is probably the best option.

OP the better way is focusing on methionine restriction. Your approach reminds me of the shitty David Sinclair approach which is to eat less food and always be cold - what a shitty way to live.
RayPeat.com has a lot of good articles with gold info on longevity.
Methionine restriction can achieve the same longevity benefits as caloric restriction, and most results are attained with 40% methionine restriction. Even stronger results could be attained by restricting tryptophan and iron accumulation in old age.
Most meat and grains have aprox 40 mg/g methionine per gram of protein. Cheese has about 30 mg/g.
Legumes, potatoes and fruit have more like 20 mg/g. Meaning you can restrict methionine by eating more potatos, legumes, fruit and gelatin.

There is a man Shirali Muslimov who is claimed to have lived 168 years - although of course some people dispute this now. He ate a diet of mostly cheese, milk and chicken broth, and lived at high altitude. So his diet is high in saturated fat, low in unsaturated fat, high in salt, high in gelatin, low in methionine, low in iron. This is probably not a bad idea to base a longevity diet on.

Yes. That's the only reason and avoiding salt is the only way to fix it.

Nice cope.
Salt causes water retention of a few pounds, but it does not cause fat retention. To get rid of the water retention you just need to drink more water and you will piss out the extra salt.

Yes, it does.

>>12663406
Why don't you just drink more water so you piss out the extra salt and then by your logic your cells will release their fat stores and your hunger should decrease and you will lose weight. It obviously doesn't work like that.
Look into athletes playing around with water weight to maintain a weight class. They are all very aware that it is just water weight and not fat stores they are tapping into.

I think for most people being in the upper limit of normal BMI like 23-25 kg/m^2 is good with about 15-20% bodyfat in men and 30% in women.
This is not set in stone for everyone though as optimal but for majority yes.

BMI is a retarded number that doesn't differentiate mass %.
A lard whale and a gorilla bodybuilder are obese according to it.

This argument just proves that BMI is largely a useful measure, both of those people would be at risk for organ damage and early death.

Except it isn't.
Bodybuilders are unhealthy because they use roids, eat animal fat and dehydrate prior to competitions, not because of their low fat and high muscle mass.
BMI doesn't work on athletes.
Can't have a random population if the method is biased.

All this shows is that individuals with high BMI are not necessarily fat, which is irrelevant when it comes to health outcomes, which BMI is a reliable measure of.

OP is a basic bitch who didn't read the article correctly

>While both generations showed the same basic results, the researchers discovered some worrying trends in the younger cohort.
>"The higher BMI trajectories in the younger generation tend to shift upward at earlier ages relative to their parents," Zheng said.

How bow dat?

>After analyzing data on how the participants' BMI changed over the years, the researchers found that the older generation generally followed one of seven BMI trajectories throughout their lives.
>The younger generation had six trajectories -- there were not enough people who lost weight through their lives to have a downward weight trajectory as was present in their parents' generation.

If you actually lose weight over your lifetimes, this study has nothing to say about you. You are a unicorn.

Nobody is talking about this missing data from the study you have noted. We are discussing people who are currently a normal BMI and can easily maintain that BMI----they are not going to live as long as people who get fatter, according to this study.
