How and how quickly does fat loss occur? During a day of eating on a deficit, is my body constantly taking energy from the fat? | Even while not in a deficit, fat is your primary avenue of energy consumption. Different intensities of exercise determine where energy is converted from. Easiest example I will use is track and field. 100-200 meter sprint= ATP-PC 400-800 meter sprint= carbohydrates 1600 meter+ = fat Now each of these metabolic pathway... |
What exactly are prions and why are the diseases caused by them incurable and untreatable? | Prions are basically a misfolded protein. What does that mean though? Well basically it's like a defective Lego. Instead of clicking together with everything like it's supposed to, it's just not a good fit. What makes them dangerous though is that instead of just not fitting together, they actually force the other good... |

Why do we so heavily vilify CO2 as a greenhouse gas when there are other far more potent greenhouse gases? | It's a complicated answer because it's a complicated system. If you hear people talking about “carbon” as the problem, with carbon credits or a carbon tax or so forth, it's specifically because they're grouping CO₂ and CH₄ together as part of the same problem to be solved together. Other times it's methane that gets th... |
How come smart phone cameras can achieve F1.5 aperture while being so cost effective while the DSLR camera can not achieve that in the similar price point. | > My simple logic would think that making the DSLR lens would be comparatively cheaper because you would not be working with miniature lens and components which will give you more flexibility in design and selecting components. An iPhone has a 4.15 mm lens diameter. A DSLR probably has a 35mm diameter lens. Why would y... |
Why do YouTube continuously find things to overlay on the videos I'm trying to watch? | You can get rid of that shit. I use Firefox with Stylish: @-moz-document domain { .annotation, .ytp-cards-button, .ytp-cards-teaser, .video-annotations { display: none !important; } } [Example] |

On top of that, appeals can take a long time, even if proven guilty. The appeals are not so much for proving the person innocent, since they were already proven guilty, but more so to prove that they don... |
Why are only certain Xbox 360 games backwards compatible on Xbox One? | One of the major reasons why only certain games are playable on Xbox One is because it is up to the developers to determine whether or not they want their Xbox 360 title on Xbox One now. I know that you might think that they could just port over all Xbox 360 games and just ask for permission from each developer as need... |
Why does abortion remain at the forefront of American politics 43 years after Roe v. Wade? | Politics. It's an easy issue to use to paint your opponent as "evil" regardless of which side of the debate they are on.People are terrible at making decisions that involve emotions.

Chemically speaking, is espresso just concentrated drip coffee? | The high pressure steam used to brew espresso likely extracts oils and other compounds from the beans that normal drip brewing cannot do. So yes, there is a chemical difference.> this would also mean that americana = american drip coffee which is clearly not true. The taste is significantly different. Sure, they've got... |
What is the sensation in the brain when I accidentally inhale a little bit of water through the nose? | The mucous membranes in your nose have a certain level of "saltiness." The water has no salt. Water molecules can pass through membranes easily; water molecules with various salts clinging to them cannot. We call this Osmosis. So the water that goes up your nose over-saturates the mucous membranes, causing pain. If you... |
Dividing 0 by 0: Why is it not 1, and on that note, what does undefined mean? | If you work it backwards , while 0x1=0, so does 0x2=0, 0x3=0, and so on and so on. Every single number times 0 will equal 0, so there is no definition or answer to the equation 0/00/0 in a **very** loose sense is absolutely any number. It could be 1, it could be -5, it could be 6 trillion, could be infinity. \r\r\rIt's... |
Why are there no independent colleges that offer degrees in just a single field (math, history,etc.)? | There are. They're just usually not well recognized, and have to be in a field that's profitable enough/can get enough students.

Why is the 'War on Drugs' considered a failure when the crime rate in the U.S. is at an all-time low? | The drug war hasn't impacted drug use at all.

the difference and relationship between volts and amperes. | Let's drop back to the hydraulic analogy, since I think it really does work if it is explained correctly. Current , in the water flow analogy, is just the water flow rate. How many gallons per minute are going through the system. Clear enough? Resistance , is how hard it is to push water through the pipe. A tiny little... |
How did "hon hon hon" come to be a French stereotype? | I come from a french household, English is my first language so while i was learning french to get the pronunciation of the words and accent correct, a wonderful trick was to plug your nose making you voice sound nasally.

You can have a layer of sand-like plastic that only bonds when a chemical is squirted ... |
Why is a court allowed to tell people they should attend a 12 step program if they are Atheist? | Judges are pretty smart folks. They send people to 12-step programs because hey believe there is a good chance that going to the program will help the person deal with the problem that's getting them convicted of a crime.

How come there are several requirements and restrictions to be able to be a parent through adoption but not procreation? | Because we are capable of reasonably restricting one but it becomes very murky and impossible to maintain when trying to restrict the other . First of all, many people consider procreation a right. So they are not going to vote in favour of that. Then, restrictions on who can and cannot procreate have been something we... |
What makes something transparent? | **Simple answer:** The gaps between the atoms is large enough that lights can pass though. **Headache answer:** Many people thinks that the reason light shines through transparent materials is because the atoms are spread apart enough, but that is not true. Even in very dense solid like lead, the spacing between atoms ... |
How come being sad makes me choose to partake in unhealthy lifestyles? | Those unhealthy things are easy to go to because they offer immediate gratification.

So as a US taxpayer you have to ask if that is the best use of the money. Many countries have partnerships like this example all over the world. So those citizens must start to ask that question to their own governments. |
Why do some lights flicker in the distance while some don't? | The ONLY reason for a light to "flicker" is if the relative brightness is changing. Being "near a mountain" doesn't have anything to do with it. The primary reason for flickering lights is changes in air density between the light and the eye. As the density changes the index of refraction of the air changes and causes ... |
Someone please explain this riddle to me. | Don't add the 27 and 2 to get 29, subtract to get 25. They each paid $9 for $27 total. $25 to pay the bill, plus $2 that the waiter kept, then they have the $3 that was given back to them. 25+2+3 = 30, it all adds up. |

Voyager 1 was launched in 1977 and is almost 12,000,000,000 miles away from Earth, yet we still receive data transmissions from it. HOW? | The probe has a nuclear power pile and a radio transmitter. We have radio telescope dishes that are sensitive enough to receive radio information from the distant parts of the universe, so even a 12-billion mile distant radio signal is enough to be received by such dishes.In short. Very, very very carefully. Radio wave... |
Why do dry erase boards become so dirty and difficult to erase fully even with a new eraser and proper pens? | This is because the special surface wears out ove time.My office actually used Dry erase paint and turned our walls into a giant dry erase board, once it starts getting hard to erase, a new coat of paint will fix it up!_URL_0_ |
What's the difference between a magnetic field, an electromagnetic field, and an electric field? | All electric charge creates an electric field. Electric charge in motion causes a magnetic field.

Jackrabbits are actually hares, and red rock hares are actually rabbits. A bunny is just a colloquial n... |
The expansion of the universe looks as though it's speeding up. Isn't that what we'd expect to see? | For the text: Hm, I think you misunderstood what the space-time is. It's not really "space and time", it's the "fabric" on which the universe is set upon. So basically, for all we can tell, it works the same way here, and it works "there". And time, as you describe it, goes by here the same as it goes by "there" . For ... |
Why do people throw up after seeing other people throw up | It potentially evolved as a survival advantage. We're a communal species, and tend to share meals. If you and Grok have a handful of poisoned berries, and Grok chokes some down first, he may be terminally poisoned. Grok's body senses this, and suddenly he upchucks all his berries, but it's too late, Grok dies. You, hav... |
What's the u/violentacrez case, and why it created such a big deal? | He was a very prominent, well-known "troll" on reddit, who moderated some controversial channels .

Which meant he got fired from his real-worl... |
Does access to free knowledge devalue it? | Just because you can lean a lot of things doesn't mean that everyone will. Learning to program for example isn't something you do over your lunch break. To become a good programmer takes many thousands of hours. Yes, it's easier than ever to learn things now. But spending some time leaning on the internet doesn't make ... |
why does medical treatment in hospitals have such hefty costs? | Medical services are generally very expensive. You have to pay a lot of money to the workers.

I want to be paid well. Oh, you d... |
Why is medicine/medical care so expensive in the USA and why is it so difficult to fix it? | Because most prices for US medical care are neither regulated by the government, nor controlled through competition. .

Also in the US, we demand to choose our doctor and still have the insurance company ... |
What exactly is the thing that sets Ruby on Rails as different from other programming languages and why is it so popular among start-ups today? | Ruby on Rails does a lot for you. It favors convention over customization. There is a certain way to do things. If you follow them, you end up building pretty good apps.

Why does sleeping without dreaming feel like it flies by between when you go to sleep and when you wake up, but when you dream it feels like you were sleeping longer? | Just because you don't remember dreaming doesn't mean that you didn't dream, but when you do remember a dream when you wake up that memory makes it seem like you were productive since you put your head down on your pillow as opposed to when your last memory is of trying to fall asleep. |
What is happening to my vocal cords when I'm sick that makes my voice all low and growly? | Vocal cords make sound in exactly the same way a guitar/piano/harp/violin string does, by vibrating. Thicker strings of equal length and tension will vibrate more slowly and create a lower tone. When your vocal cords are inflamed, they are filled with fluid. They become thicker, but their length and amount of tension r... |
Why do different countries have different power outlets? Why isn't there one universal one? | A lot of different countries develop differently. Different plugs originate based on needs such as voltage, introduction of ground pins, etc. Plus it's not like at the very beginning that countries would talk to get this universal considering its mostly electric companies. In any case, different outlets and plugs were ... |
Why do our bodies crave cold water when we're thirsty even though warm water processes in our bodies faster? | A good deal of that has to do with the fact that you were raised to expect water to be cold. In a culture where water was always served warm, you'd probably crave warm water. However, there's probably some evolutionary bias toward cold water, since running water tends to be colder than stagnant water, and is also safer... |
How we can cool things down to close to absolute zero. | There are devices called cryocoolers, without getting into details, they're really good refrigerators. If you only want to cool down an atom or molecule we can use lasers, since heat is expressed on the atomic scale as motion, we can use lasers to push the atom/molecule in the direction opposite to the direction it's c... |
How does Microsoft profit from windows 10? | Even if they give out the free version for the first year, companies and universities will still have to pay for valid licenses yearly if they decide to upgrade.

Who invented 7-day week? How do the world synchronise to week system without astronomical reference? How ancient civilisation work without week? | The week isn't directly astronomical, although it's close to 1/4 of a lunar month. The 7-day week has shown up quite a few places in history, but the modern use dates back to the Hellenistic empires founded by Alexander and his heirs. They, in turn, fed the cultures of Persia , Judea , and so on. It spread to the remai... |
Why is it that humans have favorites? Such as favorite colors, numbers and many other things favorited. | I'm not sure I understand your sentence "why is your favorite number your favorite instead of what is your favorite number" But as to why humans *have* favorites, this seems to be how animals work in general - we evaluate things and facts as good or bad, or better or worse, important or unimportant. These are evaluatio... |
Why does power typically flicker before it goes out? | This means that somewhere along the overhead power lines from the substation to your house is what is called a recloser.

How does the NSA monitoring directly affect us? | Yes, you should care: "privacy" as a legal concept is defined by community standards. Since you're part of the community, you help determine what that standard is. Anyone who can eavesdrop on you can also frame you, and that is an unacceptable position for anyone to be in. There's also the fact that any backdoors that ... |
why is my car dirtier after it rains? | The water drops cause dust in the air to stick to the car. The water evaporates and the dust stays behindRain is pretty clean, but the air is full of crap.

How much water does one need to drink? | Put simply, drink when thirsty. When it's hot do your best to drink a bit more. Saying you need a certain amount changes based on the weather, your amount of activity and your personal physiology. 9 times out of 10 you can just drink when you're thirsty and be fine. However, more people die from dehydration than die fr... |
With our much more interconnected world why don't we use a universal currency? | > It seems like it would be much more efficient. It would actually cause serious harm to the economy. Different regions of the world have different economic circumstances, and having a single world currency would tie all of those economies together tightly, so a bad economy in some other part of the world would cause a... |
How this works in politics | It differs from country to country. I assume you are talking about Trump in the US. The only, ONLY, way a sitting president gets removed is if he's convicted of a criminal offence. However, the president is not beholden to the normal justice system, since technically he runs it. So the only, ONLY, way this happens is i... |
How is coffee a hunger suppressant? | It's got caffeine in it. Caffeine is a stimulant. Stimulants can act as an appetite suppressant. |
Why is insider trading bad, and how would things be different if it were legal? | Let's say I'm the CEO of awesome-corp which is publicly traded, meaning anyone can buy or sell shares at any time to anyone willing to buy them. I know that awesome-corp is about to announce a HUGE deal so I buy up a lot of stock real quick. It's really cheap **because no one else knows about the deal but me**. The dea... |
Explain to me how fruit "ripens", more specifically how it "ripens" OFF the vine,tree, etc. | Fruit ripens when exposed to the plant hormone ethylene. Luckily for us ethylene is a very simple compound. Only 2 carbon atoms and 4 hydrogen atoms. Also it exists as a gas so is easy to expose the ethylene to the unripened fruit. The ethylene triggers the ripening process in the fruit just as it would if it was ripen... |
Why is it that people wake up when a car starts slowing or stops? | It seems your inner ear can feel the differences in motion, even when you're asleep. _URL_0_ _URL_2_ _URL_1_", 'Forces come from accelerations, a change in speed. When the car is slowing down it is accelerating, so everything inside feels that force. When it moves at constant speed there is no acceleration, thus no for... |
Why are semi-trailer trucks so deadly in crashes? | The weight difference is the biggest factor. Cars, SUVs, and pickups weigh less than 10,000 pounds. The average loaded semi weighs 80,000 pounds. Cars are also built to transport their own weight and the weight of their passengers, meaning that their frames, bodies, and suspension parts are designed for lightweight ser... |
If caffeine only blocks "sleep receptors", why am I more alert after a coffee? | Calling them 'sleep receptors' is simplifying it a bit *too* much. Adenosine circulates through the system to help maintain the balance in your neural system. At low doses, caffeine blocks adenosine receptors, which I would compare it more to being analogous to a car's brakes than to a 'sleep receptor'. So think of it ... |
Does a phone take up more battery displaying a white screen over black? | It depends on the type of screen. An LCD display uses the same amount of battery power, regardless of what's on the screen. But changing the brightness setting to a lower setting can reduce the battery usage, because LCD displays are back-lit, and turning the brightness down reduces the power the backlight uses. OLED d... |
Why don't you have to pay for data on GPSs like TomTom or Garmin, but you have to pay for data on your phone. | Your GPS unit isn't using much data. It just listens to pings coming from satellites and then uses preloaded maps to show you where it calculates that you are. Those maps are already stored as giant files locally. If they had to be downloaded as you drove around, the costs would certainly be really high though. |
How does my smartphone know where I live and where I work? | Your phone has a GPS on it. It periodically checks to see where you are. If it notices that there's a particular location you tend to be in from 9AM-5PM Monday to Friday, it tags that as "Work". If it notices there's a particular location you tend to be in nights and weekends, it tags that as "Home"> Should I trust my ... |
If using antibiotics makes bacteria more resistant, does using weedkiller make weeds more resistant? If so, why do we still use weedkiller? | Antibiotics kill off all non-antibiotic-resistant bacteria, which is then free to reproduce without competition. Weeds are the same way. We still use antibiotics and weedkiller for the same reason - they work for now, the future be damned. |
Why and how can my friend shake his eyes back and forth but I can't? | I feel like anyone can do it, you just have to know how. It's like whistling.This sounds like [voluntary nystagmus] -does it look like the video in that article? I can do it too, fwiw. |
How do music/video editing programs isolate vocals, frequency, pitch, etc.? | I don't think there's a good ELI5 answer to this, but basically it's math. Sound is a waveform, you can add multiple sounds together to get a new one. It's just like adding two numbers together. Basically if you want to isolate vocals you just do the opposite. You look for parts of the signal that look like vocals and ... |
What happens to the inmates in jail when a storm like Irma comes? | If the prison they are in is deemed to not be safe enough to weather the storm they will be evacuated to another secure facility.

That's why orange juice tastes so awful right after you brush your teeth — your tongue is picking up ... |
why are singers more famous than scientists and why does it matter? | Because singers reach a much more broad audience. The average person doesn't turn on scientific lectures in their car when they drive to work. It's all about exposure and the amount of interest people have to go and learn about things on their own. |

You'll end up needing more water than you did before drinking it in order to dilute the salt.Less. Your body actually actually has to expend water to get the salt out of your body. Plus, drinking any decent amount of sea water has a tendenc... |

Why is toilet paper popular? | You don't *have* to use cheap paper - you can buy nice stuff, you know. I suspect it's just that most people really don't care enough to make the changes needed.
