Ed. Note: Every Fat Tuesday we discuss the neuroscience of hunger, satiety, and weight control.

In the last week I’ve discovered that my eyes are bigger than my stomach. In the past, I’ve used the phrase as a euphemism for, “I just tried to cram three servings down my gullet, and gee, now I regret it!”, but now it’s quite literally true. Three weeks ago I received bariatric surgery, a roux-en-y gastric bypass, to be exact, and so my stomach is approximately equivalent in volume to my two eyes. You can’t see the transformation from the outside, but the change has been profound. I’m not merely restricted in how much I can eat, but I feel totally different about what I want to eat. I’m no longer drawn to many of the foods I used to love. In fact, just thinking about some of them makes me nauseous. Kinda like Alex Delarge’s forced classical conditioning in “A Clockwork Orange” but with junk food instead of ultra-violence, and without the actual conditioning.

Don’t get me wrong, I’m still not used to the new hardware, and I have made the mistake of eating bites that were too big, or eating too much, several times now. So I guess my eyes are bigger than my stomach in every sense of the phrase. But as a neurobiologist I find it fascinating how much my behavior and attitude have changed in response to a few staples applied strategically to my gut.

Food for thought, to be sure, and we’ll continue to discuss it as my recovery progresses.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
