But my doc says I can't burn calories by thinking about excercise?

[–] veganpizza69@lemmy.world 5 points 2 months ago

It's like the energy costs of those supercomputers used for modeling or training CNN models.

Yes. But you're not just a computer, so it's good to use the rest of your body. This isn't a cyberpunk dystopia yet.

Is it true that thinking harder actually consumes more sugar?

[–] sazey@lemmy.world 4 points 2 months ago

So apparently, a brain daydreaming or one fully immersed in a complex activity don't exhibit that much difference in energy usage, only consuming around 100 calories extra a day for mentally challenging activities.

Yes. Look at how many calories professional chess players are burning by just sitting and playing chess. You will be shocked.

Maybe, the brain can metabolize sugar or ketones. Kinda like a hybrid car that can run on gas or batteries.

Heck yeah it do. The brain is powered by glucose, and more brain activity will use much more of it. Jokingly, it's how I can tell a new engineer from one that is extremely experienced: A bright young engineer is usually skinny from problem solving all day. An older one is likely stuck in more meetings where brainpower is a liability and is probably on the heavier side.

Also, as an occasional eater of magic mushrooms, I keep packs of glucose in the house that are typically used for diabetic emergencies. Psilocybin pushes a brain into overdrive and causes my blood sugar to nosedive. (There are studies about possibly using psilocybin as a diabetic treatment to improve pancreatic function, btw..)

A new conspiracy theory just spawned in my head about the push for zero sugar products everywhere..

[–] BallsandBayonets@lemmings.world 4 points 2 months ago

Have a refreshing SodaPop Zero and tell me all about it.

This is why I just stopped thinking

[–] Viking_Hippie@lemmy.world 3 points 2 months ago* (last edited 2 months ago)

...so step one is "become immortal“?

I think I'm gonna need at least one preliminary step 😄

Same. It took me years to figure out how to preempt it.

Wait it does!?!?! No wonder I'm always tired when I'm off my ADHD meds
