Is Air Conditioning A Cause of Obesity?

It’s over 100 degrees and there’s no climate control.

What do you crave more?

A big greasy burger with salty fries?

or

Lots of fruit and salad?

In the past people ate with the seasons and not just because lots of foods weren’t available all year round but because you feel like eating different things depending on the weather.

Our bodies pick up on seasonal signals. Appetite and food preference change accordingly.

But what if you’re stuck in an office all day long?
The air is always crisp and chill. You live your life in a perpetual autumn. Winter is coming. The harvest is finished.

Autumn is the time of year for bacon, ham, apples, turkey, gravy…
So that bacon cheeseburger is what’s for lunch…every day.

I came to this realization when I performed an experiment on myself.

In the summer of 2010, I was living in Las Vegas, Nevada.

I turned off the AC for a couple of weeks just to see what it was like.

As my body tried to cope with the 110-112 degree heat, my appetite plummeted.
All I ever wanted to eat was watermelons and cucumbers.
I’d go through multiple lemons a day drinking tons of lemon water.
I relied heavily on the quinine content in tonic water to make me feel just a bit cooler and would go to sleep wrapped in wet towels.

The human body disperses heat better when it is leaner, so my body was doing its job, desperately trying to shed extra mass as quickly as possible.

By the end of my experiment, the 90 degree lows at night felt very cool and comfortable. Air conditioned buildings felt icy inside. My body was adjusting.

My trial run finished, I realized that in the past, people must have gained weight in the autumn and then lost it all again in the summer. It all balanced out.

But perhaps those ancient instincts malfunction when we live all year round at a constant ideal temperature and thus become a contributing factor behind the trend of obesity.
