Air Conditioning & Obesity

I read an article a year or so ago suggesting a possible link between air conditioning and obesity. It talked about how, in the days before central air and forced-air heat, the body's normal cycle was to bulk up when the weather started to get chilly in the fall (to provide an extra layer of fat insulation) and then to shed that extra weight when the weather broke in the spring. But since the advent of controlled heating and cooling, we're fooling our bodies into keeping the weight and then adding on to it. By not experiencing the weather fluctuations, our bodies do not have to work (and thus burn more calories) to warm up or cool down. And it starts to create a cycle... the heavier we are, the hotter we get, so we crank the air down another degree.

I think this makes a lot of sense. I have always been one for turning the air on as soon as the weather hits 80 because I hate to sweat. I'll definitely be reconsidering that this summer.

    sorry, don't remember where i read it.

    this was based on scientific study. and they did not claim it to be the be-all-end-all reason for obesity. they merely stated that it appeared to be a contributing factor (like diet, lifestyle, quitting smoking, etc).

    Correlation ≠ causation

    The advent of Aircon coincided with the advent of a lot of labour saving devices. Anecdotally, if you notice more obese people using Aircon, it could just be that being obese makes people suffer more in the heat.

    I'm not going to say it's impossible that there's a slight impact, but I'd want to see evidence before I give the theory any weight.

    Funny that I was having a conversation about this with an older friend of mine (early 70s) who is convinced that air conditioning has made subsequent generations "soft."

    As a forester for more than 40 years (very active, lots of manual labor and time outdoors) he said he ate "nary a thing" in the summer because the heat made him sick to his stomach. "Biscuit and coffee for breakfast, and then nothing but water until after the sun went down." In contrast, in cooler weather, he said he could could "eat like a horse and work like a steam engine"

    I don’t agree at all with this observation.

    Never, in all my 67 years have lived in a home with AC. More over, I live in MN where we have very cold winters, for months on end. We have festivals and outdoor activities all winter long, as well as the rest of the year. Kind of blows this theory. I became obese from overeating, and I would guess that’s true for most people. Personal responsibility is sadly lacking today. Too willing to blame something, or someone else. There’s nothing, or no one else to blame for my obesity. It lies squarely on my shoulders.

    P.S. we are having temperatures in high 80’s -90’s , with very high humidity and tropical dew points at present. We get it all here!

    Hmmmmm. Well, if nothing else, I'm probably burning a few calories wondering if the theory holds water, which I do when there's no a/c. 😯

    Hot weather makes me feel a little nauseous, so for me that can be a bonus during summer months. I don't have A/C atm and its ok. I find fatty foods and high carb foods will make me sweat a lot and feel more heated. So idk if that acually means that air conditioners cause obesity, a statement like that is a stretch! Still, I think in winter I do eat more to compensate for feeling cold, so maybe its instinctive to eat when feeling chilly. Correlations should be scientifically investigated though, maybe, if its worth the money?

    I'm the opposite, I eat less in winter and more in summer. Part is that fruit is cheaper in summer, and I love fruit. But it's a pretty identifiable trend for me, I live in the southen United States so it's warm here with mild winters if that means anything

    Just personal experience/observation, not really trying to "prove" anything on the subject. But when I was a teenager, already over 200 lb and very sedentary, I remember visiting a friend whose family did not have A/C (unheard of in southern Missouri even back in the 90s) and I had no appetite for the entire week - maybe ate a little fruit and a sandwich each day - and my clothes were baggy after I returned home...where I once again lived in a cocoon of blankets at 65 degrees and heartily chowed down on frozen burritos, cookies, etc. Then again, I was used to being cold all of the time so I'm sure that played a big part.

    It's only antidotal but true for me.

    I grew up without AC in the Midwest and my first apartment with AC was in my mid twenties.

    Once the temperature in the house reached 93 F my appetite disappeared and eating was impossible. July and August I lived off watermelon, cottage cheese, and popsicles. It was unbearable inside so all of our time was outside working and playing so lots of extra activities on little food. I lost plenty of weight each summer.

    Eating was hard but sleeping harder. It’s not something I’m willing to go back to. AC is wonderful.

    Hmmm...I've had AC my entire life and I'm not obese. I put on some weight and became overweight in my 30s, but that had more to do with going from being an active college student to sitting behind a desk all day at work.

    I tend to go lower carb in the summer too for the same reason. I absolutely cannot eat until I cool down and it has always impacted my weight a little. However, it is generally not hot enough for long enough to offset an entire 8ish other months of eating.

    The one exception to my natural desire to go low carb in the summer was usually cold caloric beverages that really add up fast.

    Well, yes, in most parts of the world and with modern and ample clothing and lighting sources - street lights ,torches etc

    Not really practical in days gone by in winters of snow and many people not having the abundance of clothing we do today nor the means to see in the dark

    Not surprising they huddled inside for winter as much as possible.

    I know myself, in a climate where it never gets low enough to snow - I am less active in winter - by the time I knock off work, it is cold and dark - the dog (and therefore me) doesnt get an evening walk, I dont get out into the garden etc
    Can imagine how that would apply even more in places like, say, Scotland, where it is so much colder and darker by mid afternoon

    and in summer I tend to eat more light meals like salads.

    If I were not tracking and controlling it, I'm sure I would find a natural greater CI in winter and a lesser CO

    That has nothing to do with air con.

    Ain't buying it. I've seen a lot of obese Russians in Russia. And when it's cold, they wear warm clothing. And turn the heat up in the home.

    I think the weight gain due to aircon is mainly something that affects women. Men have a lower feel well temperature, hence women are more likely to freeze when men feel great. So how to counteract that? Jump up from the desk far too often to just get some movement and warm hands and feet again, go to the kitchen to get more hot tea for warming up. And take cookies along from there :D
