This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

If you cut out sugar completely, your brain/central nervous system/red blood cells would break down.

We definitely consume too much sugar, but caffeine is not needed for anything.

False. The liver can synthesise over 100 grams of glycose per day, enough for the brain and the rest.

It's hard and crashy to withdraw from sugars, and it's hard because it's in all processed food and wherever they can stick it, but you can absolutely do it.

But if you pull through you'll feel way better because the body upregulates the fat to atp cycle instead of using sugar, so instead of getting hungry all the time when the body needs energy (and you are supposed to eat a donut) it just uses fat from our fat cells.

And if you eat a lot of sugar, as sugar is toxic to the body, it's used up ASAP and triggers insulin spikes etc. not exactly good for you in the long run.

Now, I guess you should try to figure out a good diet around all this of course, but sugar is just a toxic drug.

Sugar is only toxic when you get it from refined sources. When you consume whole, intact foods, in a balanced diet, sugar is totally fine and literally our primary fuel source. Our metabolic system prefers sugar as fuel so greatly that it 1) will use it over fat if available, and 2) will break down proteins in the body to get more glucose if deprived of it.

How's that acetone breath by the way?

Acetone breath? Nice argumentation.

You're just repeating what I said in another way:

  1. yes, it will use it over fat, because it's bad for us, so smartly we'll use it up ASAP.

  2. yes, other things (fat) will be used if you do not eat sugar.

Sugar is sugar, your idea about "natural" has no foothold in science, it's the glycemic index you want.

Also, if your diet is your primary "fuel source" I wouldn't like to be your arteries.

Would you care to try again and make sense this time?

[–] Valmond@lemmy.dbzer0.com 1 points 1 day ago

Oh, you're salty, lol. It's not that hard to understand.

I think they mean the bullshit that is in everything and causing major health issues, high fructose corn syrup. Everything in moderation, but easier said than done sometimes with addictive substances.

i think they mean sugar intake, not sugar metabolism
