> Isn't that the whole point of fat storage, to provide caloric fuel when you don't have access to it through food?
The whole point is to use it as a last resort to not die. Not to just use it up when you could eat normally. And there are a lot of reasons why this is the case.
First, it's what the body and your brain wants, and they make you feel like absolute shit if you don't eat. What you weigh doesn't matter, starving yourself is really really hard, because every cell in your body is screaming at you to not do it.
Secondly, it's unhealthy. Part of that can be alleviated with supplements as you say, but the other part is that your body goes into survival mode when living off your fat reserves. Your body weakens, you health worsens, your immune system goes downhill, you have less energy, and some of these effects persist even after you start eating normally again.
And then there's the problem that such a crash diet, even if you go through with it, may make you lose weight, but it won't keep the weight off. Heck, you just taught your body that "sometimes there will be no food for 6+ months", and to that, the body responds "well, then I'm going to eat literally everything I can get hold of while we do have access to food". The body tries to repair the damage and recover the lost fat reserves. So you end up regaining the weight you lost, but with some additional permanent damage to your health and to your metabolism.
All because you had this idea in your head that literally anything, including month-long starvation, was better than being fat.

Reply to ELI5: How do a bunch of lightly-electrified cells turn into consciousness? What causes the system to go from a “meat computer” to the subjective and immeasurable experience we call consciousness? by uniqueUsername_1024
I totally agree with /u/TheLuteceSibling and /u/pocketjpaul that this may be an unanswerable question.
BUT...*if* conciousness is an emergent property of complex systems (which is one of the competing theories but we may not be able to confirm), then you go into the general space of emergent properties, which is that you get properties of systems that are *more* than the sum of their parts because the "thing" is the interactions, not the parts.
A bunch of lightly-electrified cells *aren't* conscious. Dopamine isn't happy. But the interaction of a whole bunch of dopamine (and other stuff) mediated lightly-electrified cells results in a network/interactions that are conscious. It's the relationship between the things, not the things themselves, that defines the phenomenon.
It's roughly like pointing at a wave and saying "how do a bunch of water molecules make a wave?". The water molecules have no idea that they're part of a wave and "the wave", which is a perfectly visible measurable predictable thing, is made up of different water molecules from moment to moment but it's still "one wave". It's the interaction/relationship between water molecules that defines the wave, not the molecules themselves.

Look. I'm not here to argue all of the merits and issues with eating any meat in any situation. Pretty far off topic.

If the calf were sick and didn't make it then why would we be eating it's flesh? Why would we kill someone who is living a happy life and didn't ask to die?

why would we butcher someone who has a great life and didn't ask to die (likely die horribly)?

Yogi was not your average bear, he was habituated. That's why he would not leave Jellystone park. That cartoon was a poor PSA but I'm glad they cut out all of the maulings.

It's a male dairy calf. The rest of its life and how it's treated is up to the farmer. Why couldn't they have a great life pre butchering?

Does "veal" by definition necessitate that the calf is crammed in a box so it cannot use its muscles, or can it in theory include any young calf even if it lived a free and happy life somewhere but just didn't make it past a few months of age?

Reply to ELI5 When selling an item in an auction, why set a minimum reserve amount if the bidders can’t see it. Why not just set the minimum bid at the lowest price you’d be willing to sell at? by lsarge442
You don't want the bidders to know the minimum price you're willing to sell at...that gives them information that can only hurt the seller.
Suppose a bidder thinks it's worth $1000 to them, then they see the seller has set a minimum bid of $10. They're going to rethink whether their value estimate is correct. That's bad for the seller.
Knowing the other party's "willingess to pay" (minimum price they'd sell for/maximum price they'd pay) is HUGELY valuable. The entire point of price negotiations is to try to figure out this number for your opponent without disclosing your own. You don't give that information away lightly or without good reason...seller disclosing that to the bidders in an auction just hurts the seller.
Edit: had "buyer" & "seller" reversed, now fixed.

Well yes but also no. Although dairy cows are not mainly used for meat they still end up that way at the end. And you do not want old tough meat. So it is not just because of the industry but also to be profitable

The problem isn't a curious bear, it is a habituated bear. All bears are curious. They will sniff things out and try to extract food. When they are not successful they will move on. When the bear keeps getting fed it will come back expecting a food source and eager to maintain control over that food source.

Absolutely nobody have any idea about this and we are pretty sure we will never know because there is no valid scientific experiment to answer this question.
We are not even capable of telling if something is alive or not.
I’ll go further for fun.
You are alive and conscious. That’s the only thing you can be sure.
But you are made of millions of billions of alive things like cells, and bacterias.
Ok. But they are part of you, they can’t live without « you ».
Yes like ants. Ants are alive. They have pretty simple and predictable behaviors, like your cells. However, ant colonies have complex behaviors that the individual ants can’t understand. Like you and your cells. Are ant colonies alive ?
If you accept that definition and say that ant colonies are alive. What about human societies ?
And don’t start me on viruses. Viruses are just inert chemical assemblies. Well. They can be pretty complex. But they have no energy. They don’t move. They have no will. They are dead materials that just happens to have complex chemical interactions with living things. And by doing that, they also evolve through natural selection. Are viruses alive ? They are just simple things we probably could create in a laboratory with our current technology or in the near future. So they are dead assemblies. But they reproduce. And they evolve. Why ?
Good luck finding the answers. But if you want to go further, you just discovered what philosophy is about.

Reply to comment by CedarWolf in ELI5: Why do people catch the same cold every year? by [deleted]
It does, to some degree, but ultimately those *symptoms* are mostly how your body responds to threats, not the effects of the cold itself.
The bug doesn't give you fever, diarrhea, and a headache. Your body responds to the bug by inflaming the infection (more liquid/antibodies/resources for the immune system) which causes diarrhea. Your body increases the temperature because lots of bugs don't like the heat. This is your fever. Your body could increase blood pressure, too, which could result in a pressure headache, for example.
And because its your body responding, it's going to respond very similarly each time. You might always get super congested, but my most common symptom is a headache.

By the same logic, wouldn't they also have not known no kids were dead? For all they knew the shooter was holding the kids hostage and would have killed them all if they breached.

For the same reason human mothers can often pump more than their baby needs and donate (or store) the excess. The amount you (or the cow) can produce depends on the age and size of the baby and how much stimulation the breast/udder receives.

Well, yes, but I'd assume the symptoms would change considerably as it mutates each year?
Like maybe one year it causes really bad congestion, and another year it's congestion and fatigue, or congestion and cough, and so on.
WeaponB t1_iya1eq8 wrote
The symptoms aren't caused by the same disease over and over. The symptoms are what your body does to fight the virus or bacteria. The cough and sneeze and sniffles are all intended to help your body expel the invader, the fever is an attempt to bake it to death or slow it's reproductive cycle so it can be fought.
Most of the diseases that affect the respiratory system will have very similar symptoms despite being different diseases.
That being said, the rhinovirus goes around, but much like how there's a new COVID Variant every few months, there's a new rhinovirus every few months. You won't catch Rhinovirus A if you e already had it but it's been a very successful virus and has a large family of variations and you might catch any that you haven't already had.
