What's the scientific explenation behind weight gain. How do people become fat? Is it just a matter of consuming more calories than we burn, or is there more to it?

>> No.15325472

>>15325420
Pragmatically, yes, it is simply consuming more calories than spent. Behaviorally it is another beast entirely. A lot of psychiatric comorbidities align with obesity, such as ADHD, depression, and so on. There's a simple direct ultimate cause, overconsumption of calories, and behavioral causes. More controversially there may be dietary contributions, but causation is hard to disentangle due to co-occurrence of consuming "bad foods" with various psychiatric conditions.

As for why this would become so prevalent? Probably a combination of increased demands for delayed gratification to pursue ever smaller gains in life, combined with ever increasing sedentary lifestyles driven by occupational demands. Our hobbies, careers, and studying, demand our asses be planted in seats for most of our lives for most of the day in dingy rooms with shitty people, only to leave for overcrowded roads with bad drivers, to finally get home and stare at the good screen instead because you've maybe got a few hours left to start it over again.

It's pretty obvious what the "confluence of circumstances" would do to most people. Make us miserable as fuck. Not even counting psychiatric conditions in that.

Of course calories in minus calories out equals your weight gain.

But also, weight gain minus calories out equals calories in

Biologically, in ad-libidum environments like ours, the second equation more accurately describes the bio/psych dynamics. Obese individuals feel hungry due to insulin resistance and therefore tend to eat as a result of their hunger.

>> No.15325981

>>15325420
A lot of it has to do with the regulation of biochemical processes. Theoretically, when you're in a "fed" state and your body has enough ATP to function properly, enzymes from anabolic pathways such as glycogen synthesis and lipogenesis will be activated, while catabolic pathways tend to be inhibited. And when you don't get enough energy, catabolic pathways should be activated, such as glycolysis, lipolysis and beta oxydation, while inhibiting anabolic pathways. These enzymes can be activated or inhibited in a lot of ways, mostly by the amount of food you eat, but also by hormones (notably insulin and glucagon), epigenetics and probably a good amount of other factors

Lol, how much of a fucking troglodyte do you have to be to think the only difference between Japan and America is mercury consumption?

If you are that desperate to find an environmental excuse for your laziness and stupidity, try glyphosate, high fructose corn syrup, microplastics, atrazine, onions, SSRIs, narcotics, etc. Maybe stop consuming so much mercury and you might be able to figure these things out yourself.

Really it's calories absorbed and stored. A person doesn't absorb every calorie of every gram of food ingested. Calorie counts come from bomb calorimeters, not humans. Also, they are based on averages of standard samples of macronutrients in bomb calorimeters. It's not 100% accurate to say that every gram of protein you eat will result in your body absorbing 4 calories, for example. If you eat a stick of butter, you won't absorb 810 calories. You'll probably end up shitting out about half of them undigested. Counting calories listed on packaging and websites is useful, but not entirely accurate. Also, this concept of burning a certain number of calories by doing a certain exercise for a set amount of time is seriously flawed as well. It just depends on the person.

Really, it all comes down to metabolic privilege vs disprivilege.

Some people are metabolically privileged to have a body that responds to a simplistic CICO model, where less consumption and more exercise directly result in weight loss; others are metabolically disprivileged and need to work directly against their body's tendency to preserve adipose tissue to prevent weight gain.

As with most scientific fields a lot of the research is lacking due to researchers being unaware of their own metabolic privilege and the biases it causes and refusing to listen to people with different body types

The calorie information is based on what's absorbed, not the actual chemical enthalpy.

I disagree, but I'd be interested if you could find me evidence for this claim.

>> No.15326511

>>15325420
indeed it's CICO, but this obviously lacks a lot of important detail. WHY do people eat more than they burn? this then gets into the science of appetite. it certainly isn't any kind of "free will".

also, metabolic privilege is real. there are people who burn unusually high calories. if you're dumb enough to think that everyone has the same or even similar metabolic rates, you need to reassess.

There’s some studies that point to gut flora influencing weight gain. Eating certain (junk) foods can alter gut flora, which in turn begins to crave those same foods and extracts more calories from the food (thus meaning instead of processing 2000 of 2500 calories, you are processing 2400 of 2500 calories.

>> No.15327298

Ultimately it is calories in minus calories out, but if people don't eat filling foods (protein) then they are going to increase their caloric intake. So stop fucking eating, fatty.

We have evolved in an environment where the calorie surplus was not present, and even a stable trickle of calories was not guaranteed. So our metabolism is fundamentally adapted for hunter gatherer lifestyle. We do have some additions for agricultural/pastoral lifestyle, but the industrial/postindustrial adaptations have not manifested themselves yet.

Look at salt. Animals in the wild consume it without any reasonable restraint because it's very rare in nature and so it would be advantageous for them to overdose on it right now because they usually live in the environment with the lack of salt. Same for us, basically every single human consumes more salt that is needed for normal living (it might be correlated with the high number of heart attacks throughout the civilized stage of human existence)

Average caloric consumption means nothing unless they exclude everyone who isn't a normal bmi.
Otherwise you get dataset contamination from the ogres downing 12000kcal a day.
I 100% guarantee you that anyone in any country on planet earth that is maintaining (read not slowly gaining weight) is eating at what their personal maintenance intake is, or within a very very reasonable margin of error.

i was always skinny, and in winters i would gain a couple of kgs which i'd easily lose (within a week or two without fasting or any care about food) in the spring. never ever was i fat.

after ~3 months of postcovid (puking, rash and all sorts of other shit) i lost ~20kgs. i thought it was a disaster because it was always very hard for me to gain weight. but fortunately after i got better i returned to normal weight within ~3-4 months. but then it went the other way and i started gaining weight. after i gained ~10kg over my normal weight i started doing things to prevent it, exercise, better eating but it didn't go down, which absolutely shocked me, i always lost weight by just not overeating. after many months i managed to get it under control but it was like - not my body. i guess my metabolism changed, and now i can understand fat people.
