Skip to comments.Meat-heavy low-carb diets can 'shorten lifespan': study
Posted on 08/18/2018 11:03:44 AM PDT by fireman15
Middle-aged people who get roughly half their daily calories from carbohydrates live several years longer on average than those with meat-heavy low-carb diets, researchers reported Friday. The findings, published in The Lancet medical journal, challenge a trend in Europe and North America toward so-called Paleo diets that shun carbohydrates in favour of animal protein and fat. Proponents of these "Stone Age" diets argue that the rapid shift 10,000 years ago -- with the advent of agriculture -- to grains, dairy and legumes has not allowed the human body enough time to adapt to these high-carb foods. For the study, receiving less than 40 percent of total energy intake from carbohydrates qualified as a low-carb regimen, though many such diets reduce the share to 20 percent or less. At the other extreme, a 70 percent or higher share of carbohydrates -- such as pasta, rice, cakes, sugary drinks -- can also reduce longevity, but by far less, the scientists found. "Low-carb diets that replace carbohydrates with protein or fat are gaining widespread popularity as a health and weight loss strategy," said lead author Sara Seidelmann, a researcher at Brigham and Women's Hospital in Boston. "However, our data suggests that animal-based low carbohydrate diets might be associated with shorter overall lifespan and should be discouraged." Replacing meat with plant-based fats (such as avocados and nuts) and proteins (such as soy products and lentils) reduces the risk of mortality, Seidelmann and her team found. The optimal balance of food groups for longevity remains hotly debated. Many studies have concluded that eating carbohydrates in moderation -- 45 to 55 percent of total calorie intake -- is best, but others report improved short-term, cardio-metabolic health with high-protein, high-fat diets.

Starvation will limit life even faster.
So bacon is good or bad?
Makes sense. What was the average life expectancy 10,000 years ago, when everyone ate a Paleo diet?
And/or PETA and/or Econazis.
Meanwhile, I'm throwing some steaks on the grill tonight.
A meatless diet doesn’t really make you live longer. It just seems like forever when you can’t enjoy it.
I lost 94 lbs of flab from 2015 on a low carb-high fat diet.
34 days ago I began a zero carb way of eating & lost all my depression/anxiety symptoms, lost all lower back pain I had had for 10+ years, lost all joint pain, lost skin tags, lost soured stomach & did I mention I lost the depression/anxiety symptoms?
Carbs = poison
sugar = poison
meat = health & healing
fat = energy
Just click your heels and a new study appears with the opposite findings.
The diet that has worked for me is whole foods....processed as little as possible, no added ingredients. Two 4oz (or so) meat servings a day. Whole grain bread and cereals. Next to no milk fat. No mystery sauces. Plenty of fruits and veggies. And I'm not tired. The other item on my "diet"....two brisk walks ever day and an AM upper body exercise routine.
I know there's no diet that works for everyone. But a diet that leaves out vitamins and minerals? It doesn't pass the common sense test.
Freepers, please enlighten me where I err.
[I am not a dietician and cannot speak with authority about the nutritional costs and benefits of Paleolithic diets, but I can comment on their evolutionary underpinnings. From the standpoint of paleoecology, the Paleolithic diet is a myth. Food choice is as much about what is available to be eaten as it is about what a species evolved to eat. And just as fruits ripen, leaves flush and flowers bloom predictably at different times of the year, foods available to our ancestors varied over deep time as the world changed around them from warm and wet to cool and dry and back again. Those changes are what drove our evolution.
Even if we could reconstruct the precise nutrient composition of foods eaten by a particular hominin species in the past (and we can’t), the information would be meaningless for planning a menu based on our ancestral diet. Because our world was ever changing, so, too, was the diet of our ancestors. Focusing on a single point in our evolution would be futile. We’re a work in progress. Hominins were spread over space, too, and those living in the forest by the river surely had a different diet from their cousins on the lakeshore or the open savanna.
What was the ancestral human diet? The question itself makes no sense. Consider some of the recent hunter-gatherers who have inspired Paleolithic diet enthusiasts. The Tikigagmiut of the north Alaskan coast lived almost entirely on the protein and fat of marine mammals and fish, whereas the Gwi San in Botswana’s Central Kalahari took something like 70 percent of their calories from carbohydrate-rich, sugary melons and starchy roots. Traditional human foragers managed to earn a living from the larger community of life that surrounded them in a remarkable variety of habitats, from near-polar latitudes to the tropics. Few other mammalian species can make that claim, and there is little doubt that dietary versatility has been key to the success we’ve had.
Many paleoanthropologists today believe that increasing climate fluctuation through the Pleistocene sculpted our ancestorswhether their bodies or their wit, or bothfor the dietary flexibility that has become a hallmark of humanity. The basic idea is that our ever changing world winnowed out the pickier eaters among us. Nature has made us a versatile species, which is why we can find something to satiate us on nearly all its myriad biospheric buffet tables. It’s also why we have been able to change the game, transition from forager to farmer, and really begin to consume our planet.]
Note that the article is talking about healthy carbohydrates rather than sugar and white bread and such. Just saying “carbs” is pretty misleading.
Most people following low carb diets are doing so as weight loss strategy and are coming off of eating unhealthy carbs (sugars, refined grains, processed foods...).

Looks like ADM is fighting back. Has to scare them that people can actually cure diabetes by simply refraining from most carbs.
Looks like the cat’s out of the bag now!
That’s awesome sir.
I don’t put much stock in these “studies”, a paleo style diet is quite good as I compare it with how Bible people ate. They lived til hundreds of years old heh.
“34 days ago I began a zero carb way of eating & lost all my depression/anxiety symptoms, lost all lower back pain I had had for 10+ years, lost all joint pain, lost skin tags, lost soured stomach & did I mention I lost the depression/anxiety symptoms?”
So, how much are you BEING PAID for making the above claim?
Answer: ZERO - no one here even knows who you are. To put it another way, you have no have no reason to lie. But the researchers for this article...it would be interesting to find out where their funding comes from.
10,000 years ago, the meat hunted you back.
Heck, even 200 years ago.
There is no reason not to take a multivitamin & magnesium on a lo-carb diet, and I do just that along with D, extra C and a few other things.
Many woman past 50 don’t absorb B12 well and need supplemental B12 by another route. In earlier times they got B12 shots now there are some good products applied daily as a pump of skin cream, one example MAXASORB BioActive B12 Cream.
That is the first thing I suggest to friends and they have reported good results. Since that is a “does no harm” suggestion I am free with the advice. After that point there are many things unrelated to diet that cause fatigue and a medical check up for the most common would be best.
Tell that to a cat.
Yeah, thanks to you. There's millions to be made "treating" diabetes but people like you want to reverse it. Sure, people can be happier, healthier and leaner but what's the fun in that when Big Pharma can "help" you.
True. I do find I feel better when I lay off the carbs. Less cravings.
