Hunter-gatherers vs Westerners

from your link, and from Dr. CampbellI am the first to admit that background and academic credentials are certainly not everything, and many interesting discoveries and contributions have been made by "outsiders" or newcomers in various fields.0

I have a good theorized explanation for this:
Hunter-gatherers are on their feet EVERY DAY, getting exercise nearly the entire time they're awake. One thing exercise does is increase the efficiency of your body. The more efficient your body is, the fewer calories it will burn.
Makes sense, right?
So even though they're on their feet 12 hours a day, their bodies are so adapted to doing it, and they do it so much, their bodies don't have to work as hard to do more work. thus, their calorie usage is lower.
Also these people are probably a LOT lighter than the average desk worker, so their "normal" BMR will be a LOT lower.
Now, desk workers are NOT active, and a LOT heavier, so their BMR is higher.
Put two-and-two together, and you'll have equal calorie expenditure.
Now, if you got a desk worker to go out and work in their feet every single day, their calorie expenditure will be a LOT higher than the hunter-gatherers.
I'd like to add what I know bout this ultra-marathon runner I've watched a documentary on. His resting heart rate is 32 beats per minute. 32!!!! Mine is 50-60 some-odd, as is most of yours, I imagine. The slower your heart beats, the fewer calories you burn (it's a good guideline to follow - there are exceptions). In a race, he can run non-stop for 24 hours. In that time, he may burn as many calories as someone who is sitting at a desk all day. Does this mean you shouldn't bother going out to exercise, because the super athlete burns as many calories as you do while sitting at a desk? Heck no.
I feel this is the way people are thinking after reading the article. People need to think more about what they read... Srsly.
^Everything I was thinking. Thank you!! :drinker:0 -

He was being polite. She basically has no credentials. And besides we are talking about MY CRITERIA, not Campbell's. I said that I have never heard a REPUTABLE SCIENTISTS make the klnd of claims you did about the China Study.
I still haven't.0 -
I tell you why paleo/primal is so big tight now. The same reason that Pepsi Max and Coke Zero are.... they are targeted to men.
They use languages and images that most heterosexual men feel comfortable with... so while your average men would rather eat **** than to say they are on the Dukan diet most guys are quite happy to say that they eat like a cave man.
PS: I know many women who like this way of eating and the same for gay men, but there is certainly something real macho about this whole plan which there was a gap in the market for before.0 -

Polite or lying? Because if you are saying no useful information ever comes from the "non-scientific",,,,,, well have a great boring life.0 -
I went to your first site and found an article by Denise Minger, who may or may not even have a Bachelor's Degree but certainly has an agenda. Her criticisms might impress someone who know nothing about statistics, or who hadn't even read the book, which I assume you haven't, but they are not,. overall impressive. They did apparently cause a big stir, and T Colin Campbell himself responded to her, on a different web site:
http://www.vegsource.com/news/2010/07/china-study-author-colin-campbell-slaps-down-critic-denise-minger.html
LOL, is there a way to do a LOL even bigger, because this is so funny I'm actually LMAO right now, in fact hold on while I go pick my A up of the floor. "She has an agenda", really? you posted that while at the same time posting a link to discredit her, from VEGsource web site? LOLLOLOLOLOLOL I hope you do see the humor in that.
The reason I posted more than one "slap down of the China study, was so you would get a well rounded slapping down. Try the last one it's a short video, and the guy their talking to has a Dr. in front of his name since you put so much faith in people with letters in front or behind their name.
I do find it the epitome of humor for a veggie to be lecturing ANYONE about their diet, try this test, go drop yourself off in the middle of nowhere and try to survive as a veggie for a year, no supplements, no health food stores, just eat what you can gather.
The Vegesource article contains a comment by T. Colin Campbell to Ms Minger. I think that is highly relevant, don't you? Especially since Ms Minger censored responses on her own blog that she didn't like or agree with.
And why on earth would I want to drop myself off in the middle of nowhere and try to survive. Hello, we are no longer living in the Ice Age. We have a civilzation where the problems you are worrrying about have been sovled thousands of years ago. Why would I not want to eat a diet that is right for THIS CIVILIZATION. As I said previously, you are free to go out and eat bugs and worms, and slugs, and whatever you can catch (Bytheway I assume that if you were planning to be dropped in the middle of nowhere you would bring a rifle with you. Now that is a really good paleolithic tool!)
You can prepare for living in an extinct society all you want. I choose to live in the one I have. You can ignore progress of the past several thousand years if you want, but I actually even doubt you would do that. As I said you would probably bring a rifle, penicilin, a first aid kit, and other tools to live the TRUE paleolithic lifestyle. Bet you wouldn't eat too many bugs or worms either.0 -
Are you exercising as much as they do?
I do believe exercise can control weight, and I am somewhat suspicious about this study because the results are counter intuitive (doesn't make them wrong, of course.)
I do not give any credence at all to the "Paleo" diet, but it stands to reason that a farmer who works all day in the field burns more calories than a typical sedentary American.
You give no credence to the "paleo" diet (love the talking marks, makes me thing you're talking about someone's dirty socks...)? Interesting. Now I'll bet if I said I give no credence to the "vegetarian" diet you'd have something to say about that eh? Not that I do. My daughter is a staunch vegetarian in a paleo/primal family and if we're talking about hunter/gatherer's then there it is. Just what is it about my 'no grains/refined sugar/processed foods/limited dairy' diet that lacks credence?
I give no credence to the Paleo diet for a number of reasons:
1. Nobody knows what that diet really was. We have only a few spotty indications of what paleolithic man ate, and most Paleo references to sources for their diet that I have seen refer only to Ortzi, who was actually a NEOlithic human. Since he was frozen in a glacier, the contents of his stomach were also frozen. Most of the time at Paleolithc sites, antrhopologists have to examine what remains at the site to try to ascertain what the diet was.. These could be seeds, bones or even poop. Diet obviously varried from site to site, depending upon what was available. From what I know there was no "Paleolithic Diet" as such, just some meager information about what the diet may have been in a few places.
2. Even if one knew what the Paleolithic Diet was, it probably could not be reproduced exactly, since both the plants and the animals may have been genetically different from what they were today. And most likely a large part of the Paleolitic diet may have been scavenging kills from sabre tooth tigers, and other carnivores, or eating plants that are genetically different from what we eat today.
3. Since paleolithic man spent a large part of his waking life avoiding danger and trying to find food, I doubt you can compare his lifestyle with modern man. Lifestyle may have been a big part of the "success" of that diet.
4. Most evidence indicates that the Paleolithic diet was not a success. Paleolithic man lived to be 35 - 40, and so never lived long enough to demonstrate that he had any advantage regarding the diseases of old age (cancer and heart disease) over us, since he died before these diseases normally present.
5. The few studies I have seen on those attempting a Paleo diet indicate it is either neutral or harmful.
6. There are obviously better choices. No study I have ever read indicates that any chronic disease is associated with vegetarian diets, for example.
Thus my reasons for dismissing the Paleo diet are 1. no one knows what it really was, 2. even if we did we could not reproduce it, 3. it was the diet of a specific lifestyle which no longer exists, 4. there is no evidence that the paleolithic diet, which was a diet of necessity is any better than any other diet, 5. there is evidence that it is worse than other diets, and 6 there are a lot of studies which demonstrate fairly conclusively that diets with no meat are better for those who wish to live longer lives than diets with meat.0 -

I'm living in Tanzania right now, and what amazed me at first is how my neighbors stay fit given their diets. Lots of carbs, lots of fried foods... granted, many are farmers and do get a lot of exercise, but their portion sizes are huge!!! I'm always getting comments about how little I eat, and yet, I've gained weight on a Tanzanian diet, despite exercise. It's hard to account for the difference, unless we consider my previous eating habits (what my body is used to) and ancestry/genetics.
That's really interesting! So, maybe the hunter-gatherers were underreporting their food intake. Another sad study comes to mind though, and that's the one from earlier this year that said that people who lose weight burn fewer calories than people who are the same weight, but have always been that weight.0 -

The theory behind the Paleo diet is that it mimics the diet the human race had "for miilions of years." I belive you were the one who said that.
No I was not the one that said that. I would say it's "based" off what the human race did for millions of years, which by the way wasn't vegetarian or vegan, just thought I would throw that in there. Based off, as in, we use science and common sense to understand what the human evolved or was designed to eat, and try to use that as a basis for what we put in our bodies.
**************
Really? That is interesting and I would really like to know how you know that. Also, I ask again what are you talking about? Austrolopiticenes? Homo Erectus? Anatomically Modern Humans? Homo Sapiens? What. Everything you are saying is vague, and depending on what you are talking about , very likely wrong.
**************Now you are saying it is just a name with no particular reference to anything in our pre history.At least I believe that last bit is true, however, most paleos honestly believe that they are "eating like a caveman."based on false science with no nutritional, historical or anthropological evidence behind it.
not true at all, just because you over look the science and historical evidence does not make it so.
***********************
Again technical subjects like nutrition require technical expertise. I am not willing to bet my life and health on some freelance writer for the New York Times who wants to sell books to gullible people.

As a hunter, I can tell you that a lot of it is sitting and waiting for the animal. Sure, there is walking from stand to stand, or trailing a deer but for the most part it's a waiting game-at least for my dad and me it is.
You have never turkey hunted have you? Last time I went I think I clocked about 25 miles of walking per day looking for a good Tom.
The weapon probably also makes a difference. You don't have to actually chase a deer and stab it with a spear anymore.0 -

Hopefully in grade school you learned what average meant. That is wonderful and a credit to our public schools for at least teaching that.. However, unless you have better information than anyone else, you cannot say what portion of the population during paleolithic times lived beyond 40. Yes, some certainly did. However without modern medicine, hygene, and protection from pathogens, wild animals and other dangers in the environment, I would doubt many did. If you have any information about some Paleolithic men living 100 years then please share it. As for me, I will take the "average lifespan of 35 years" to mean there weren't a whole lot of AARP candidates around then.Let’s take a look at the Kitavans, since there’s so much data on them. A healthy, seemingly happy, peaceful culture in the Trobriand Islands in Papua New Guinea eating a Paleo diet. At the time they were studied in the late 1980′s, they ate tubers, fruit, fish, and occasionally pig, and they didn’t suffer from heart disease, obesity, or other common ailments of Westerners.
In fact, none of the 213 adults surveyed had any memory of anyone having chest pain or spontaneously dying (as from a heart attack). Oh, and they smoked like chimneys. Anyway, yes, their average lifespan was lower than ours, but it doesn’t mean that people didn’t live to be very old, even into their 100′s. Here’s the breakdown:
According to this study, their average lifespan was 45 years, which doesn’t seem that old, but it averaged out to that because a lot of children died of malaria. Once they reached adulthood, their chances of reaching old age were possibly about the same as Westerners. 6% of the population was 65 or older (compared to 12% in the U.S.). Their activity level was high, but not outrageously high. And none of the elderly seemed to suffer from dementia or poor memory. When the Kitavans were very old and it was their time to go, they would just stop working one day and go into their houses and die within days.
Wow! You are basing your health on the diet of a tribe of 200 people living on an island in the Pacific. What a huge sample! What a fine isolated community (ever hear of genetic drift?) And by the way, their diet was 70% CARBS! 10% PROTEIN, 20% SATURATED FAT. Sounds healthy to me. Maybe I'll just go an eat a stick of butter, followed by about 10 candy bars. Yum! I'll have a handful of nuts for my protein.
Bytheway, you can also find studies about Lapplanders and Inuits who live on equally unhealthy diets. They have been cut off from other populations for a long time, and those who could not tolerate the diet, forced bythe environment, have long since died off. The Meat and Dairy industry loves to sponsor studies involving Lapplanders and Inuits, but I am sure these people have significant differences in genome from the wider population.0 -

Sure, right. And how many hours do I have to waste trying to prove a negative. Forget it. If you can't prove you know what you are talking about, I will simply form a logical opinion about what you believe.0 -

I dont understand opposition to a diet that encourages people to eat unprocessed food like meat, fruits and vegetables. To my understanding there is no limit on carbs unless your trying to lose weight, as long as they come from fruits,vegetables and tubers. I do not believe the pale or primal diets actually mandate any carbs, or fat ratio.0

Because it includes meat, and most of those that come on here and deride it, are veggies. It's not hard to understand once you understand their agenda.0 -
its odd that a diet encouraging meat, vegetables, fruits and tubers is considered a fad. but a diet that includes fake soy meat is not.0

From the article:
"In fact, the Hadza spend a greater percentage of their daily energy budget on physical activity than Westerners do"
Huh? What exactly are the Westerners spending their energy on, then...? (if they are apparently expending the same energy)
Is this straight up energy consumption? Is this consumption per lb of body weight? Per lb of body fat? This summary of the actual research is fairly meaningless without more detail.
I agree. It didn't really explain the study very well.0
