Food fight: CO2 makes us fatter

Well, this is amusing. But, after looking at some numbers on food production, it may simply be that CO2 is helping us grow more food. And what happens when a well fed population has more food? It eats it of course. The caveat is that correlation is not always causation, the Green Revolution (the agricultural one, not the crazy one) and Norman Borlaug had a lot to do with this too.

From ScienceNordic: New theory: CO2 makes you fat

Danish researchers have announced a rather wild hypothesis: Perhaps we are getting fatter and fatter because of the increasing CO2 levels in the atmosphere.

I had to laugh at this “fact” sidebar in the article:

Researchers are wondering whether CO2 affects embryos in the womb, so the embryos develop a tendency towards obesity.

This is one of the hypotheses that will be tested if the researchers can raise funding for large-scale trials with rats.

Gosh, giant CO2 fattened people and fat rats. These might do well with the smaller climate optmized green cat-like overlords from our other crazy story this week.

Other excerpts (tinfoil hats optional):

CO2 makes us eat more

This discovery made it possible to develop a precise hypothesis for how CO2 makes us fatter: We breathe more CO2, which makes our blood more acidic; this affects our brain, so we want to eat more.

In 2011, together with researchers Anders Mikael Sjödin and Arne Astrup from the University of Copenhagen, Hersoug started to test the hypothesis on humans.

At the university’s Department of Human Nutrition, they placed six young men in special climate rooms, where some of them were exposed to increased amounts of CO2. After seven hours, the men were allowed to eat as much as they liked.

This little pilot study showed that the men with the greater amount of CO2 in their blood ate six percent more food than the men who had been in climate rooms with a normal amount of CO2.

“We could also see that the extra amount of CO2 caused the men’s heartbeat to rise, and this gives us an indication that CO2 affects the brain’s nerve cells – orexins in the hypothalamus – which among other functions control our appetite and the composition of our nutrient intake,” says Hersoug.

“A very small change in the activity of these nerve cells will presumably have great importance for our development of obesity or for maintaining our weight.”

Does CO2 give men beer guts?

If the researchers’ hypothesis is correct, it raises many questions.

CO2 is found in the bubbles in fizzy drinks and beer – does that have any importance for obesity?

“Of course I have considered whether CO2 has very local impacts, which could explain how beer guts develop,” says the researcher.

Exercise and vegetables can limit the ‘CO2 effect’

But Hersoug says the hypothesis gives us no excuse for dropping diets and exercise – on the contrary.

“We know already that a sedentary lifestyle is a risk factor for many diseases,” he says. “According to our theory, this may be because of the higher acidity in the blood arising from a sedentary lifestyle indoors in a CO2 concentration that is higher than it is outdoors.”

On the other hand, he says, “If you’re out running, you get your blood circulating and you can pump much of the CO2 out of your body, so our hypothesis is really further evidence that exercise is healthy. And exercise may be even more necessary in the future, when we can expect even higher CO2 concentrations in the atmosphere.”

Hersoug adds that fruit and vegetables also reduce the blood’s pH value, so the CO2 theory is also an argument for eating more healthily.

Oh noes! Blood acidification – the next CO2 scourge! Breath deeply, it worked in The Andromeda Strain. Do not panic.

I hope this is a misrepresentation of the foundation of their study:
“At the university’s Department of Human Nutrition, they placed six young men in special climate rooms, where some of them were exposed to increased amounts of CO2. After seven hours, the men were allowed to eat as much as they liked.”
A sample size of 6 people, with a 6% difference in consumption means precisely nothing.

A study involving six males is being extrapolated to 7 billion people. That sounds reasonable.
Apart from that isn’t there a contradiction in there? They say:

We could also see that the extra amount of CO2 caused the men’s heartbeat to rise..

Surely that means they are metabolising faster and so will need more food to replace what their body has consumed.
On the other hand, the faster metabolising means other researchers will be able to claim more CO2 causes malnutrition.

From vague memories of high school physics, I remember something about how respiration is controlled. Basically out body measures the level of CO2 in the lungs, and when it reaches a threshold point, we breath.
Seems to me that if the level of CO2 in the atmosphere were higher, this threshold level would be reached more quickly. (This is why I doubt higher CO2 in the atmosphere would result in higher CO2 in the blood)
As a result, the respiration rate will increase. More movement of the diaphram ( a pretty big muscle after all) could explain why the heart is beating a little faster.
Faster breathing, faster heart rate. Sounds like more calories getting burned.

Like everything else about our body, it accommodates to its environment. Go to altitude, climb a mountain, be a little hypoxic in the rarified air, breath more deeply, blow off CO2, voila we have more buffering bicarbonate in our blood than needed to balance CO2. This is especially true for our slow accommodating system, our spinal fluid. Ultimately, we develop “mountain sickness.” Walk down 600 feet and sleep the night away, and our kidney has time to dump the excess bicarbonate from the blood, a couple of days later, bicarbonate leaches out of the spinal fluid, and voila, we have accommodated. People do live at 15,000 feet, work and play etc.
Add CO2 to our environment and all sorts of things happen acutely; but, just wait a few days, and our body accommodates to higher environmental CO2 concentrations by…the kidneys keeping more bicarbonate until we have re-established a balance between CO2 and its buffer bicarbonate. Voila, in a short time, we are back to what we originally were, an eating, thinking, moving machine. The US Navy has done a lot of experiments on the environments inside submarines for 6 month stints, including sustained elevation of CO2. Since space is limited in a submarine, food, fat, and function are all considered long before sending sailors in nuclear armed nuclear powered submarines for prolonged submersion cruises. Information is available for those inclined to look before they leap.
A final note: although from our present environment we inhale 400 ppm CO2, we exhale 40,000 ppm CO2. Our body seems to accommodate a very large “flux” in CO2. The CO2 we exhale has to get from the cells to the tissues, to the blood, to be pumped to the lungs to be exhaled. The buffering capacity of our body is dynamic and constantly adjusting to its… environment.
The authors seem to be extrapolating acute exposure data to long term changes in behavior; i.e., eating more. Chronic exposure data with behavioral changes requires a lot more evidence to pursued me.

Can we have a moratorium on bio/medico/nutrition grads until they take statistics courses for grown-ups. It seems that most of the problem the AGW crowd has had is screwing up statistical studies. We may not know if it will be hotter or colder in the next 100 years but we sure can tell when the statistics supporting it is a load of crap. These 6 subjects (along with a few dozen more to join them) should have had their food intake individually measured daily over a period of a few weeks before going to the CO2 rooms). Off the top of my head I’d say a 6% variance among 6 people is rather a small one. The larger sample would also have determined if the numbers were significant (for example, say 75% of the CO2 crowd ate more and 80% or so of the ambient bunch ate the same as before and less than the other group).

March 13, 2012 1:26 pm

The exercise raises blood CO2 levels so high you have to pant to get rid of it versus the CO2 you breathe, at several orders of magnitude less, affects you so severely you have to eat more paradox definitely deserves examination – I think they’re onto something here and more funding should provide an answer !
These people have become totally STUPID – if the CO2 we breathe in was at concentrations capable of affecting us more than the existing concentration in our blood (a waste from metabolic processes) our gas exchange mechanism in our lungs would be compromised, we would all be permanently gasping for breath BECAUSE our bodies rely on CO2 concentrations to provide the involuntary breathing reflex – not lack of oxygen but too high CO2 levels in our blood controls this.
Note it is only CO2 (outside of such things as tear gas etc) – the by product of metabolism – that produces this response – we do not really notice CO until we die.

Offering logical counter arguments to something this inane is a complete waste of time, but as they say in “The Godfather” or maybe GF II, “Every time i think I’m going to get out, they drag me back in”. One would assume that anyone with intelligence greater than a turnip would have noticed that almost all of the increase in atmospheric CO2 is supposedly the product of burning fossil fuels to create various forms of energy. Almost all of that energy is used in ways which significantly reduce the amount of metabolic energy humans need to expend to accomplish the necessary tasks of daily life. That is usually considered to be a good thing. Thanks to current abundant supplies of energy we can live our lives with much lower levels of physical effort than our less gifted ancestors. But even if we could magically produce that energy from zero CO2 sources, the effect on the number of ax handles across the collective human ass would be negligible.
If you really want to stay thin, go back to walking to every place to which you want to travel. If you want information, hike yourself to a library and drag a bunch of heavy reference tomes off the shelves instead of doing a search engine inquiry on the internet. Make all of your choices in life based on similar logic and you’ll never have a problem with obesity. Of course your affect on the climate will be many orders of magnitude less than that of that apocryphal butterfly whose flapping wings upset so many climate models. I strongly suspect that you would have exactly no success in recruiting other humans to join you in an impossible attempt to expand that influence.

Sorry to disappoint the fluffy readers here (yours truly incl.), but the high-CO2 rooms were at 8000ppm. I’m guessing that beer, popcorn, and computer usage are more significant factors than 380ppm.
For reference, the OSHA (i.e., workplace) permissable exposure limit is 5000ppm and the level immediately dangerous to life or health (IDLH) is 50,000ppm. No wonder the subjects’ hearts were beating a bit faster.
For your further amusement, here’s the conflict of interest statement from the article:

Out of interest I came across the following info on biscuits:
Over 491 billion Oreo cookies have been sold since they were first introduced
Nabisco turns out 320 million pounds of snack foods annually.
It costs $72,000 if you want facts and figures on biscuits in 80 countries from Algeria to Vietnam. It’s only $900 dollars if you want just one country. http://www.euromonitor.com/biscuits

As office buildings often run at 5000 ppm CO2, submarines at 8000 ppm, and rock concerts can reach 12,000 ppm CO2, it’s clear that a tiny rise in CO2 will make people eat more. It’s simple cause and effect.
After a day working in 5000 ppm CO2 people go home and eat because of the CO2 . . . or was it the work they did . . . so . . . they eat dinner because lunch was so 6–7 hours ago.

Temps: have risen ~0.5C
My weight: has gone from less than a kilo to 100 kgs. So let’s say a 100 kilo rise.
So going by the long term trend the correlation is 14 ppm / 0.1C / 20 kgs. If we extrapolate this out to 2050 we find that I will be 200 kgs!!!!

That is why I made the joke about the CO2 putting more sugar on the high fructose corn syrup.
This “Study” isn’t worth lining a bird cage with.

Actually CO2 DOES make us fat it is all that extra sugar in the corn syrup that Coca Cola puts in your soda. CLICK

Yes but the artifical sweetner is found to increase appetite and cause weight gain… BUMMER!

Artificial Sweeteners Linked To Weight Gain
ScienceDaily (Feb. 10, 2008) — Want to lose weight? It might help to pour that diet soda down the drain. Researchers have laboratory evidence that the widespread use of no-calorie sweeteners may actually make it harder for people to control their intake and body weight…. http://www.sciencedaily.com/releases/2008/02/080210183902.htm

The reason seems to be the effect on insulin levels.

….Fowler’s team looked at seven to eight years of data on 1,550 Mexican-American and non-Hispanic white Americans aged 25 to 64. Of the 622 study participants who were of normal weight at the beginning of the study, about a third became overweight or obese.
For regular soft-drink drinkers, the risk of becoming overweight or obese was:
26% for up to 1/2 can each day
30.4% for 1/2 to one can each day
32.8% for 1 to 2 cans each day
47.2% for more than 2 cans each day.
For diet soft-drink drinkers, the risk of becoming overweight or obese was:
36.5% for up to 1/2 can each day
37.5% for 1/2 to one can each day
54.5% for 1 to 2 cans each day
57.1% for more than 2 cans each day.
For each can of diet soft drink consumed each day, a person’s risk of obesity went up 41%. http://getfitslowly.com/2008/02/12/the-dangers-of-diet-soda/

This BTW with a sample size of 1,550 is much more like the type of study I want to see!

Primo Levi, in his book The Periodic Table writes of the smallest amounts of carbon dioxide (and water vapor) present in the atmosphere “without which there would be no trace of life on the planet.” That’s us! The weather is nature’s delivery service of these elements to the forests, fields and gardens of the globe. The weather begins with “warm air rising” (CO2, H2O)Man’s production of CO2 , millions and millions of tons joins nature’s release of CO2 and H2O. Global warming is part of the weather, global warming is the weather, EXTREME weather, weather on the rampage, gales gone wild, weather on steroids – heat energy. Follow the energy. The science behind the weather is the transmission of heat through fluid media – convection. Heat is energy.

THE PB&J CAMPAIGN
You recycle. You choose organic.
You conserve energy.
Now take at-home environmentalism
to the next level.
Each time you have a
PB&J
you shrink your carbon footprint,
YOU REDUCE GREENHOUSE GAS
emissions and water pollution,
you cut back on habitat destruction,
AND YOU CONSERVE
How does this work?
It’s actually not ONLY about the PB&J. Any plant-based
meal you eat instead of something based on meat, fish,
eggs, or dairy products can have a big impact.
Find out more about how this works.
How much can you accomplish?
You might not end global warming in one lunch break, but
each time you choose the plant-based meal you make a difference, just like taking out the recycling or taking public transportation to work instead of driving.
Ready to take the PB&J Pledge?
A healthier planet, one meal at a time.

Click on the “how much can you accomplish” link. Interesting numbers. So switching a simple steak or fish fillet for a highly-processed paste of legumes, oil, and sugar, with flavored gelled sugar water, between two slabs of processed fungus-treated ground grass seed, will help save the planet?
Logically, the most savings in carbon emissions and water and land resources would come from selecting non-farmed food. So we should all be allowed, if not mandated, to freely secure meat wherever it is naturally found. So those with rural access can hunt and fish for whatever they can get whenever they can. For the liberal elites who don’t venture out of the urbanized areas due to lack of public transportation and the limited range of their electric vehicles, start working down the excess pigeons and spare cats.

Is that the water vapor dampening effect? If so, then that negative forcing will eventually stabilise positive forcings and we’ll reach equilibrium.

And don’t forget that the calculations have to be done with Kelvin units.
The average temperature of the earth is sometimes said to be about 288K. An additional 1C, or 1K (the same quantity) works out to an additional 0.3% of energy. Too many people make the mistake of working in Celsius and discard the 273.15 units below 0 Celsius.

I asked my daughter, who has been a cashier at a local popular grocery store for several years, what morbidly obese people have in their carts and she’s seen a definite trend: They select sugar-rich foods and diet soda.
That’s it. No fruits, veggies, and very little meat. Seems they wash the sugar down with the CO2-rich soda.
Ah HAH! There’s the connection–that insidious CO2 hiding in that diet soda is “wot done it”!
I have all the evidence I need to agree with this study from ScienceNordic.

As best as I can tell, the study makes no attempt to measure subjects pCO2 (partial pressure of CO2 which is a measure of blood CO2 concentration) or blood pH, which according to their hypothesis would be the critical intervening variables between atmospheric CO2 concentration and regulation of orexin, ghrelin and leptin. Yes, the subjects exposed to increased CO2 did breathe a little faster (we’re not told by how much). However, this is a well established effect regulated by chemoreceptors in both the peripheral and central nervous systems. Moreover, the study yields no information as to the likely effect of a CO2 enriched environment in the longer term. Blood pH is well buffered and further regulated by renal mechanisms to deal with acidosis which might well offset the impact of what might well be a minute change in pH (indeed, we have no evidence that pH actually changed in any of the subjects). The increase in food ingested did not reach statistical significance. I’m amazed anybody bothered publishing this given the manifest flaws and gaps in the research (maybe it was a slow month for the journal at the time in question).

As usual, I’m confused:
In 1975, annual C02 production was about 2000 million metric tonnes. In 2010 it was about 3000 million metric tonnes. Atmospheric C02 increases by Mauna Loa haven’t changed much since 1975, while the stuff going into the air has increased by 50%. So the planet has become THAT much more efficient at absorbing CO2?
First: I don’t believe the global C02 figures. It is in the interests of every government who supports CAGW to report the higher, rather than lower, estimates of CO2 production. The more in, the “worse” it is and shall be. I’ll bet every value is rounded up. Second, I don’t believe the world is MORE efficient at removing CO2 than before.
This is what I believe: 1) global CO2 figures are considerably lower than the warmists say or think, and 2) natural systems naturally grab and use CO2 so that it “disappears”. By that I mean biological systems and limestone buffering.
Still, as a dispute point with the warmists, one must ask: where is all the CO2? If, like the “missing” heat, it is hiding, there is another source of research funding you need to find.

At the university’s Department of Human Nutrition, they placed six young men in special climate rooms, where some of them were exposed to increased amounts of CO2. After seven hours, the men were allowed to eat as much as they liked.

A very realistic simulation of what’s happening in the atmosphere – “seven hours”. / sarc

Great, but before the FDA starts regulating CO2, I think we need to remember that the law of diminishing returns applies here. Consumption might go up at relatively low levels of CO2, but as you approach concentrations of one million parts per million human food intake will drop to zero. So this is a self-correcting problem. Glad I could help clear that up.
I totally need to make a hat like that for my daughter’s cat tonight and post it on my facebook.

Good grief the sample size was not even SIX because some of the guys (3?) were the control! I would be ashamed to even call this an experiment.
I also wonder how much “bored out of their skulls after seven hours in a closed room” played in stimulating the appetite this “experiment”
