Low-Protein Diet May Extend Lifespan

Soulskill posted about 5 months ago | from the suddenly-i-feel-much-healthier dept.

Medicine 459

sciencehabit writes "A new theory about the foods that can extend life is taking shape, and it's sure to be a controversial one. Two studies out this week, one in mice (PDF) and another primarily in people (PDF), suggest that eating relatively little protein and lots of carbohydrates — the opposite of what's urged by many human diet plans, including the popular Atkins Diet — extends life and fortifies health."

This sounds suspiciously like the USDA food pyramid. That would be the thing that we have already tried with disasterous results.

Anonymous Coward | about 5 months ago | (#46402371)

"lots of carbohydrates" doesn't mean "lots of bread, grains and pasta" - fruits and vegetables are a source of carbohydrates.

Basically, this is just confirming what we have already known for many years, but some of us refuse to admit: the best diet is one that is high in fruits and vegetables, and meat should be eaten in small portions (if at all).

The best diet is probably a balanced diet of about 1200 calories a day. The safest way to avoid getting hit by a car is not to walk across streets or drive a car. The safest way to avoid dying via plane is to not fly, etc...

We never really tried the food pyramid. What was disastrous was going out and eating 80% carbs and 20% fat. We assumed we were eating healthily, when in reality diets like the above are suggesting more of a balance, rather than doing ridiculous things like cutting carbs.

You will also note that the article didn't mention weight loss, it mentioned health. We have this weird idea that being thin is the same as being healthy, which is on many levels, ridiculous.

This. Atkin's diet is only a good way to lose weight in that you are malnourished.

Re:Atkin's Diet (1, Insightful)

mythosaz (572040) | about 5 months ago | (#46402553)

Done right, the weight loss on Atkins is two-fold. You do burn fat from ketosis, but the primary means of weight loss through Atkins is simply eating what you would have eaten before - just without all of the empty carbs.

Want a cheeseburger for lunch? Have it. Just leave off the bun and onions.
Wanted chicken wings at the bar? Have 'em. Get them "naked" with a hot sauce instead of a sweet one.
Going out for steak? Fine. Trade the baked potato for a side ceasar.

As long as you don't use "because Atkins!" as an excuse to put bacon and cheese on everything, you'll be fine.

Re:Atkin's Diet (2, Insightful)

Desler (1608317) | about 5 months ago | (#46402613)

Riiight. Because the 150-175 calories from the bun is the tipping point on having a burger not the 300+ calories from just the fat from the beef (assuming 1/2lb. Of 85/15 beef). As the saying goes, that's being pennywise and pound foolish.

Re:Atkin's Diet (1)

Bartles (1198017) | about 5 months ago | (#46402719)

Cutting the fat never worked for me. When I restricted carbs, after about 5 months I was in better shape than I ever have been in since puberty. I lost 45 lbs. It works, whole grains beings good for you is the biggest load of BS. It's not about calories for the most part, but the type of calories.

Re:Atkin's Diet (1)

Desler (1608317) | about 5 months ago | (#46402839)

It probably didn't work because you were still getting too many calories from carbs. It's always about having the right percentage of calories from fat/carb/protein for your metabolic level.

The point that I was making is that it's silly to cut out 150 calories when the rest your meal is still like 1500 calories. It's basically a nonsense gesture so that people think they're being healthy by doing next to nothing at all.

Re:Atkin's Diet (0)

Anonymous Coward | about 5 months ago | (#46402765)

Except that the bun doesn't significantly contribute to your feeling of having a good meal, compared to the burger. So let's assume that burger is exactly 300 calories, and the bun 150. Without the bun you'll feel about as full as with it, except you ate only 33% fewer calories. Reducing your calorie intake by 33% is going to make you lose weight.

Re:Atkin's Diet (1)

But it is the calories. Eating 20,000 calories from protein is still going to make you gain weight.

Re:Atkin's Diet (1)

bobbied (2522392) | about 5 months ago | (#46402797)

Not exactly. What Adkins is doing is keeping you malnourished in carbohydrates, forcing your body to find them someplace. Your body cannot process the fat calories ingested effectively so they are eliminated, not being used. Seems that the easiest source of carbohydrates is your internal fat reserves to keep your blood sugar in the survivable range.

Problem is that you really are malnourished on Adkins; Lacking carbohydrates. That can lead to issues with kidneys and most other systems in the body. Plus, it is REALLY hard to eliminate carbohydrates enough to make this work. Most of us don't eat that way. And there is a reason, it's not healthy in the long term.

Re:Atkin's Diet (1)

mythosaz (572040) | about 5 months ago | (#46402833)

You're missing the point.

I made very clear that a good Atkins meal was a skinless chicken breast with a green vegetable side, not covered in bacon and cheese.

...but you want to argue fat counts in ground beef. Atkins eaters can make simple substitutions to their daily life, and enjoy the occasional cheeseburger, and enjoy change. Not loading up on unnecessary fat is what separates people being successful with carb-restricted diets and not.

Re:Atkin's Diet (2)

Billly Gates (198444) | about 5 months ago | (#46402929)

The reason for different kinds of calories is that carbs and sugars spike insulin levels.

To add what I posted above, this is like ordering a supersized double quarter pounder meal from McDonald's and being "healthy" by having a Diet Coke.

Re:Atkin's Diet (1)

mythosaz (572040) | about 5 months ago | (#46402757)

Well, if your previous meal was a super-size double quarter pounder meal, and you now, instead, order a super-size double-quarter-pounder meal "Atkins style" -- bunless, no ketchup, no onions with side salad instead of fries and a diet soda or water, you've cut HUNDREDS of calories out of your previous meal.

-550 calories on the fry-to-salad substitution alone.

If you cut 600 calories per meal out of your normal routine, you'll lose weight -- or at least stop gaining it as fast.

Nobody thinks you should eat McDonald's every meal for good health -- Atkins or not.

Not as I understand it.

Carbs:
1. Boost insulin which promotes fat formation.
2. Make us lazy.
3. Reduce satiety.

Such is the effect, it seems you can eat more calories via Atkins and still lose weight.

Um, I'm not an Atkins proponent (been vegetarian since the seventies) but part of that was marketing by Atkins detractors. He slipped on ice and suffered a severe blow to the head. In the hospital, he contracted another condition (which escapes me at the moment) which caused bloating. There is an urban legend that militant vegetarians (which always struck me as an oxymoron, but never mind...) snuck in and got photos of Atkins on his deathbed as rather disingenious "proof" that his diet killed him.

Re:Atkin's Diet (1)

mythosaz (572040) | about 5 months ago | (#46402501)

People like to say "Atkins" as an excuse to just eat bacon and protein bars.

Actually following the diet plan sensibly , is fairly healthy. Eating 20 grams of carbohydrates a day - to begin - and then ramping up slowly as you near and reach your ideal weight is fine -- as long as you don't use it as an excuse to eat slabs of bacon and cheese.

A grilled skinned chicken breast and a green vegetable is a great Atkins meal - and a good meal on almost any diet plan. Frying it and smothering it with bacon and cheese is what idiots do - the blame Atkins.

Ron, an elderly man in Florida, owned a large farm for several years. He had a large pond in the back.
It was properly shaped for swimming, so he fixed it up nice with picnic tables, horseshoe courts, and some orange and
lime trees.
One evening the old farmer decided to go down to the pond, as he hadn't been there for a while, and look it over.
He grabbed a five-gallon bucket to bring back some fruit. As he neared the pond, he heard voices shouting and laughing with glee.
As he came closer, he saw it was a bunch of young women skinny-dipping in his pond.
He made the women aware of his presence, and they all went to the deep end.
One of the women shouted to him, "We're not coming out until you leave!"
Ron frowned, "I didn't come down here to watch you ladies swim naked or make you get out of the pond naked."
Holding the bucket up Ron said, "I'm here to feed the alligator."

Full article indicates the human study was based on a one-time interview with participants. Even then (FTFA): "as the NHANES cohort aged, protein became more important. In the over-65 crowd, those who ate lots of protein survived longer, on average, than those who ate less."

So, sort of, maybe, but not.

buchner.johannes (1139593) | about 5 months ago | (#46402695)

Any reasonable recommendations can only come from large, longitudinal studies, over multiple generations. You know, those that shape the food pyramid / WHO guidelines. And they do exist, and give pretty clear ideas. Such as that halving your meat intake is a good idea.

But I guess that's not exciting, news needs to either repackage (MyPlate) or go after highly fluctuating results from microstudies which is the latest research, but in the stage of formation (all these diet fads, X is bad for you, Y heals cancer, drink a glass of red wine a day [because a encyme in a petri dish did something], etc. ).

By the way, why does there need to be one right way of nutrition? Why can't we accept that multiple ways to obtain the basic building blocks are possible.
In the end, we can't be so off by so much: We have so many people living with such a big variety of foods, and they are doing pretty similarly well (i.e. get older than, and are healthy at, 65). The need to prove that everyones diet is completely wrong is ridiculous.

Protein isn't the problem. (1)

GoJays (1793832) | about 5 months ago | (#46402435)

Eat well balanced and in moderation and you'll be fine. The most harmful things in your diet are sugar, (sucralose and fructose) salt and processed foods.
Protein is needed for the retention and development of muscle. Eliminating it while keeping your sugar intake high is a recipe for type 2 diabetes, heart disease and living a life of obesity.

See, if you'd stopped at the first sentence you'd have been fine. Once you wandered off into processed food land you became either a nut case or wholly redundant. See, there's nothing wrong with sugars of just about any type (though lactose is not digestable properly by a portion of the population, but that's a side discussion), nor salt, nor processed foods.

Once you eat a well balanced diet of proper portion sizes, you never need worry about the rest of the stuff, as it takes care of itself. A diet of Coke, Twinkies, and bacon is not a balanced diet*, so there's really no need to go spouting off about it.

*this, fwiw, is proof that there is either no God at all, or that God hates us. Because in a universe with a benevolent God, those would form the core of a balanced diet.

Longo’s team used death records to conclude that those under 65 whose self-reported diets they classified as high-protein"

After years of personal training in my experience alot of people have no idea what foods have high protein, also using a "survey" of questionable nature (most people lie on surveys) to come to such a large conclusion without alot more supported data is bad science.

In a perfect world, that's what would be said. But in a world where money is on the line, we'll get the same old mix of conflicting recommendations based on how and by whom the various organizations get paid.

exercise? (1)

spads (1095039) | about 5 months ago | (#46402551)

seems like the mimimum should be to enforce some kind of exercise. it doesn't get much more sedentary than lab animals. thus, if the results are actual (??), the findings should be low prot high carbs preferable IF SEDENTARY. (though that seems somewhat counerintuitive as well).

for about a couple of million years the early humanoids through to modern humans until about 10,000 years ago ate nothing but a high protein diet mainly meat. To sustain a low protein diet you have to eat a high carb diet. So I do not see how that can make you live longer as you are getting obese with type 2 diabetes.

Eat less (0)

Anonymous Coward | about 5 months ago | (#46402583)

Eat less of everything. Skip all the stupid fad diets and studies. Consume 1500 or fewer calories a day, exercise mildly. Live longer and more disease free. My science angel told me this.

Protein's Turn For Demonization (4, Insightful)

organgtool (966989) | about 5 months ago | (#46402641)

In the late 80's and early 90's, fat was the energy source of the devil that needed to be avoided at all costs. Then in the early 2000's, carbs were the new nutrient to avoid. And now, another decade later, they're telling us to avoid protein. I'll stick to eating a variety of foods in moderate portions supplemented by exercise, thank you very much.

I'll stick to eating whatever I please in whatever amounts fit into my gizzard while still getting perfectly fine blood tests and 110/60 BP.

What I find interesting is that both the vegans (Fuhrman, McDougall, Ornish) and the low-carbers (Atkins, etc) all get great results for their patients, and the common factor seems to be the elimination of SUGAR (a carb) in the diet.

What good is it to live a long time if you can't eat what you like to eat?

The four basic food groups are good enough for me - caffeine, nicotine, bacon, and pussy. Without those, life has very little meaning.

These studies (1)

oldhack (1037484) | about 5 months ago | (#46402671)

They are mere flip, a datum likely shoddily collected that is so far removed from any kind of conclusion. It might be worth a mention among specialized crowd that deal with the narrow subject, but outside of that rarefied circle, its being reported is worse than useless.

So we are like mice? (4, Insightful)

ras (84108) | about 5 months ago | (#46402741)

As others, the study was done on mice, who are herbivores in the wild. They say what happens to them will also happen to us, but we have been eating meat a long while now.

I wonder if also applies to my cat? <scarcasm>I know cat's are predominately carnivores, but that shouldn't matter, right?</scarcasm>

Re:So we are like mice? (1)

Akaihiryuu (786040) | about 5 months ago | (#46402953)

I know you said that in jest, but I've seen a LOT of people make serious comments like that. Cats are acutally obligate carnivores, they can live entirely on protein and fat. They have absolutely no metabolic need for carbohydrates. Their digestive systems convert protein directly to glucose.

Re:So we are like mice? (1)

avandesande (143899) | about 5 months ago | (#46402963)

Yes what was the protein source- soybeans, meat, albumin, casein? It's hard to believe that all proteins are metabolically identical.

Sigh do you even RTFA? (2)

WillAffleckUW (858324) | about 5 months ago | (#46402771)

It doesn't work for older people in the first place, and we're only talking IGF-1 cancer.

Look, want some useful science?

Vitamin supplements are mostly a waste of time, if you're not about to get pregnant or participate in that, and you're far better off eating a varied diet low in meat with more fruits and vegetables, and getting mild to moderate exercise.

There, free of charge.

Most of the rest is just noise.

Now, go get enough sleep and stop doing binge diets and binge drunks and stuff that stresses you out. If you want to fast for a week or two every ten years (if you do this, take vitamins and fruit or vegetable juice), that also helps.

Re:Sigh do you even RTFA? (1)

iggymanz (596061) | about 5 months ago | (#46402919)

noise? you make assertions without proof, and if you're referencing the much-bandied study led by Dr. G Lamas, that one was only looking at cognitive function and heart heath.

  And even he admits vitamins of benefit in targeted populations with various malnutritions.

in short, cheap insurance at least. and at most could be some major benefits in other areas of health.

Re:Sigh do you even RTFA? (1)

WillAffleckUW (858324) | about 5 months ago | (#46403005)

I'm presuming that we're not addressing a lot of populations with severe vitamin deficiencies here, as they tend not to read slashdot.

My advice stands.

But I get the distinct impression that what diet is "good for you" is determined by what foodstuff the agricultural commodity markets feel is undervalued this year.

Was the study sponsored by the sugar industry? (1)

Johnny Loves Linux (1147635) | about 5 months ago | (#46402911)

Seriously, I don't see how the study could be right. My experience is that I lost 63 lbs. in 4 months by eating a low carb, high protein, high vegetable diet. The fastest and physically easy technique was to just ditch the sugar drinks, candy, fries stuff.

Which kinds of protein? (1)

Anonymous Coward | about 5 months ago | (#46402979)

Good research has shown that red meat is particularly harmful to the cardiovascular system due to it's interaction with gut microflora. But other kinds of protein seem to be healthy (nuts, chicken, etc.).

So what kinds of protein do they use to test their hypotheses?
