Freaky Friday: Stay Awake And Get Fat

How’s that for a sweeps-month, scare-the-snot-out-of-you type of headline? Yeah, it’s something that’s almost guaranteed to get your eyeballs glued to the page, wanting to see more about this.

All I’d need to do is throw in the words free and sex and maybe iPhone and I’ve got a pageview magnet. Still, it’s not all about the pageviews. This here is a real thing.

According to a recent article in The New York Times, losing sleep over the fact that you’re overweight (or, really, for any reason at all) is a pretty sure way to actually make yourself gain more weight.

Losing sleep tends to make people eat more and gain weight, and now a new study suggests that one reason may be the impact that sleep deprivation has on the brain.

The research showed that depriving people of sleep for one night created pronounced changes in the way their brains responded to high-calorie junk foods. On days when the subjects had not had proper sleep, fattening foods like potato chips and sweets stimulated stronger responses in a part of the brain that helps govern the motivation to eat. But at the same time, the subjects experienced a sharp reduction in activity in the frontal cortex, a higher-level part of the brain where consequences are weighed and rational decisions are made.

In other words, your brain is hitting you with a double whammy. Your body is craving a hit of that sweet, salty, fat load of goodness we call junk food. And, just when your body most needs to have your brain in control and exercising a little restraint, the part of the brain that’s in charge of restraint goes out for a well-deserved vacation, leaving instant gratification in charge for a while.

Not a good combination.

Of course, it was possible that we, the sleep-deprived masses, simply craved more food because our bodies had to make up for the calories expended when we stayed awake instead of sleeping soundly. It was possible to believe it until this new study came out, that is.

“Their hunger was no different when they were sleep deprived and when they had a normal night of sleep,” (said Matthew P. Walker, an author of the study and a professor of psychology and neuroscience at the University of California, Berkeley). “That’s important because it suggests that the changes we’re seeing are caused by sleep deprivation itself, rather than simply being perhaps more metabolically impaired when you’re sleep deprived.”

Least you think this is all made up, let me assure you that the link between lack of sleep and weight gain is one that has been well established by a number of studies throughout the year. It’s real. Sleep less, weigh more. Not only that, but sleep deprivation can inflict a whole host of other potentially deleterious effects on your body. This new study, though, really focused in on what happened in the brain when the subjects skipped sleep and then started drooling over different food pictures.

The research showed that when the subjects were bleary-eyed and sleep-deprived, they strongly preferred the food choices that were highest in calories, like desserts, chocolate and potato chips. The sleepier they felt, the more they wanted the calorie-rich foods. In fact, the foods they requested when they were sleep deprived added up to about 600 calories more than the foods that they wanted when they were well rested.

At the same time, brain scans showed that on the morning after the subjects’ sleepless night, the heavily caloric foods produced intense activity in an almond-shaped structure called the amygdala, which helps regulate basic emotions as well as our desires for things like food and experiences. That was accompanied by sharply reduced responses in cortical areas of the frontal lobe that regulate decision-making, providing top down control of the amygdala and other primitive brain structures.

All of which goes a long way toward explaining why dudes make such bad choices the day after an all-nighter. And when I say dudes, I mean, of course, mostly me. Who hasn’t woken bleary-eyed from a night of tossing and turning only to find themselves making a direct line from bathroom to cupboard, searching for that one last donut?

Bit takeaway health tip here, dudes. Make sure you get enough sleep, even if only to avoid eating more donuts. Save ’em for me.

Freaky Friday: An Armful Of Ear

by Richard

Losing a body part, dude. . . That’s tough. It’s not like losing some hair or a nail. That stuff grows back. But as soon as you get to stuff that can generously be called parts — teeth, eyes, organs, limbs — that’s when the limits of nature’s regenerative bonus ends.

Well, for primates, anyway. Just ask Curt Connors about how well taking after the lizards goes for you when you try to regrow an arm.

Still, scientists have found a way to do Dr. Connors one better. They’ve managed to begin growing replacement parts for humans in a way that doesn’t leave the subject as a slavering, aggressive hybrid of man and lizard, with a thirst for mutated spider blood.

Sherrie Walters lost her ear to cancer. A fast-growing basal cell cancer in her left ear forced doctors to remove it in 2008, along with part of her skull and ear canal. Now, though, she’s got it back.

In a groundbreaking and complicated set of surgeries, Johns Hopkins doctors have attached a new ear made from Walters’ own tissue.

The cool part about this is how doctors kept the nascent ear growing and healthy.

“I thought of this exact strategy many years before and really was looking for the right patient to try it on,” said renowned plastic and reconstructive surgeon Dr. Patrick Byrne.

Byrne used cartilage from Walters’ ribs to stitch together a new ear matching her right ear. He then implanted it under the skin of her forearm, where it grew for months.

“We started making jokes just to try to get used to it and I was like, `Can you hear me? Can you hear me?’ said Sherrie’s husband, Damien.

 Byrne later surgically attached the ear and its blood vessels. Following that surgery, doctors went in again to shape the ear so it looked like Walters’ other ear.
Tell me this wasn’t cool.
Every time I think we’re facing an abomination of science and we’re going to need to get out the pitchforks and the torches, along comes something like this that renews my faith in the ability of mankind to muck around with things that are better left alone. And it actually works.
There are some things that man was not meant to know. Apparently, growing an ear on someone’s arm wasn’t one of those things.

Freaky Friday: Crawlin’ Crabs

by Richard

Remember how I told you dudes that I was finally climbing up out of the sea of red ink and was almost able to breathe again after working so hard on the edits for the book Barry and I are having published, A Dude’s Guide to Babies?

Yeah. I was wrong about that.

Not about the book. That’s still being published in spring of 2013, no question about that. Only I was wrong about being finished with the edits. Our esteemed editor, Torquemada, has come back with another set of edits and wants me to get to work on going through the text to see if he messed anything up or if I did. Most likely it’ll be me.

Anyway, while I’m working, I thought I’d step back here and give you something to get creeped out about. Or by. Or over. Something like that. Why creeped out about instead of something over which to go oooohhhh and aaaahhhh? Sorry. You should know by now, that’s just not me, dude.

I love hermit crabs. Can’t get enough of them. Or so I thought. Right up until I saw this video. And then that sound. . . that crunching, squinching sound of all those claws scraping over all those rocks and shells. . . that chitinous clicking. . . Ew!
