Site is a link aggregation of a series of blog posts that cite various studies about the mystery of why the obesity rate is increasing, and why the rate of increase is itself accelerating. Authors make a compelling argument that normal homeostatic processes (the theorized lipostat specifically) tend to keep people within a certain BMI range. Authors argue that environmental contamination is breaking the lipostat, driving obesity rates upwards, and faster where there's more contamination.
Interesting read and a great reason to switch to :vegan-v: with a focus on not buying anything wrapped in plastic.
Your body is not a dumb machine. It is perfectly capable of letting calories run right through it when it doesn't need them.
This study is literally rejecting the calorie-counters' hypothesis, so the emphatic defense of it here is really quite perplexing.
'here is a study about how obesity is actually a more complicated issue than we realise'
'what is this anti science bullshit losing weight is easy CALORIE IN CALORIE OUT CALORIE IN CALORIE OUT CALORIE IN CALO-'
this is literally the opposite of what i said, but go off
fair play - it was more directed at 'its not complicated' than anything else, considering this study is emphatically saying its more complicated than we have previously realised
sure, but it's literally not complicated. your body cannot create fat from nothing. everything that ends up stored in your body as fat, you have to first put into your body. and if you dont put enough in your body for it to function on, it must burn what is already present in your body, starting with previously stored fat. it is literally that simple.
the complicated parts are social and mental, which are entirely valid. however, before we can focus on the issues at hand we must first agree on what those issues are, which means accepting the very basic and undeniable parts like the simplicity of the calories in / calories out system.
agreed for the most part, but as someone who has done CICO multiple times and failed to hit my final target weights, despite being someone who used to be super active (including a whole pre-transition gym bro bit), it can kinda irk me when we leave discussions at simply 'CICO is easy, its just maths' since it really is the whole picture that is complicated - focusing purely on the numbers in and out, and talking up how simple that is can leave the implication that if it's not working for you, its a personal failing
i know that's not your intention, i totally get where you're coming from but I think you can't really separate out the mental side of things from the numbers side when it comes to discussions about how 'easy' it can or can't be to follow CICO
then how do people get fat
According to this study, one major cause is signaling getting fucked up by environmental contaminants.
Alternatively, some people's bodies naturally tend a bit heavier (an advantage in times of famine). For them, calorie counting can work fine. And everyone's body is likely to take on some amount of reserves when it's easily possible to do so, but this tendency varies quite a bit.
But the obesity epidemic goes against all of that. It used to be rare to be obese, and extremely rare to be extremely obese, the latter usually caused by some signaling issue (thyroid, I think). Now it's extremely common. HFCS is 55% fructose vs the 50% in table sugar; it's not helping but it's not so different it could cause the epidemic we're seeing.
unless you're talking about differences in people's skeletal structures or something, no. there's no such thing as "naturally heavier." your body creates and burns fat the same way mine does. if you have a greater proportion of fat stored on your body than i do it is because the ratio of calories you eat vs calories you burn is higher than mine.
there are a wide variety of reasons it might be difficult for a person to eat fewer calories than they burn but none of those are that the gods just decided to bless them with excess fat from thin air
The same way, sure. But that doesn't mean there's no variation in people's metabolic signaling systems, which are astonishingly complicated. Every node in all of those signaling pathways is a protein encoded by a gene, which means every one is a source of potential variability between different people.
Edit: here's a poster showing just a part of a teeny-tiny fraction of the metabolic signaling system, namely the insulin receptor system.
Of course, there's plenty of variations. But that doesn't make the actual process each individual needs to do any more complicated. Let me put it this way: If you don't eat, you will lose weight. Right? We can of course agree on that. On a similar note, if you simply do nothing but eat cookies all day, you will gain weight. Now, in between those two extremes, there will be a certain amount of food you can eat which will cause you neither to lose nor gain weight. Eat 10% less than that, and you will ... lose weight.
That's why it's simple. It doesn't matter how complicated all the systems of your body are because you don't need to know all that. What you actually need to know is very simple.
See the way you say simple makes it feel like you're saying "easy," like, here's a pat answer so stop complaining about it. You know full well, though, that a starvation diet, leaving aside the awful health implications, is simply impossible to actually do for enough time to achieve useful results. So I argue that the answer you're pushing, then, is largely worthless.
I'll note that my problem is that I can't seem to gain and keep weight, quite the opposite of most people's, and I find it roughly as impossible as the obese people do to work against that. (Oh but all I have to do is eat more, right? Except that the body regulates food intake via appetite, doesn't it? And if you ignore that and overstuff yourself, your body will be quite willing to just forcibly eject the excess food by vomiting--I have personal experience on this point.)
But those are two different things and I don't know how to stress that any more than outright saying it 2 hours ago in my first actual comment on this topic
I never recommended a "starvation diet" I was trying to establish a baseline on which we can both agree so that I could construct the actual, practical argument I was making. And yet, no matter how clearly I lay this out, you still try to argue with it because you're not actually conversing in good faith. You're not paying attention to what I'm actually saying, you're just looking for anything at all that I say that you feel like you can interpret in the least charitable possible way so that you can write out a hostile argumentative reddit-tier debatebro comment that "scores points"
No, not exactly. What you have to do is eat more calories. Not just more volume. If you try to gain weight on a watermelon only diet yeah of course you're going to throw up because that's impossible. Your appetite is largely based on the volume of the food you're eating (because of course that's what literally fills up your stomach) and your weight is determined by the caloric content of the food you're eating. That's why relying entirely on your appetite is insufficient, because it doesn't measure the part of the food that actually determines whether you gain or lose weight.
Except the phrase "it's simple" can be interpreted as being applied to the CICO logic, or to the process of trying to apply that logic. It fits for the former, but does not for the latter. My entire point is about the complicating factors that make the application of your simple logic into a near-impossibility. Your entire point feels semantic, honestly.
And look, everything I eat is incredibly calorie-dense; I eat a typical shitty American diet. I studied biochemistry in college; I know all of this. And yet I still can't maintain a weight of over 130 fucking pounds, and people who sound an awful lot like you do right now like to tell me how it's all my fault and I fucking hate them for it.
Under the CICO model, does every calorie eaten count as a calorie "in"?

Wow, that's really interesting! This is exactly what I meant about the body not being just a dumb machine--it adjusts to its environment and situation in ways that we're only beginning to discover.

that sounds awesome, i wish metabolism actually worked like that in the real world

That's a self-reported number from literally one guy lol
I'm fairly certain that the average person's body will burn more than 800 calories per day in a comatose state, there's no way in hell that number is accurate. This is a common broscience talking point and nothing in the paper cited in that article suggests that your metabolism can be permanently altered by weight loss.
Edit: a bedridden, 120lb, 80-year old man needs >1000 calories per day just for normal body functions

this is an extreme example
Sadly it just seems to be far more complex in this. The human body is very smart with regulating intake with the foods it evolved to eat, that's not true of modern processed foods and snacks. When you eat a banana or an apple, you digest lots of things like fiber and vitamins, and your body feels satisfied with it, because it's designed to see that intake as food and respond accordingly. Many of these foods take a while for a body to digest and use up the energy in them, leaving us to feel full for a long time.
When you eat a bag of almost pure sugar filled cookies, it's completely out of whack because nothing in history has prepared it for this. All of the amazing indicators that we've developed to tell when we're full aren't there, our blood sugar and insulin spikes hard and then drastically begins to drop in just a few hours causing us to feel very hungry again. It's not that the body is stupid, is that what you're putting in is literally not what it's designed to expect.
You can test this for yourself too, I certainly have. I used to sit there and eat half a family size Oreos (with milk!) in a single sitting and I would still desire for more. Meanwhile if I cook a potato or eat a banana, I can only get though two potatoes or three bananas max before I feel like Ive had way too much. In my quest to eat healthier, I've noticed that the foods I eat have substantial impact on how I feel for that day, and once you start paying attention to this it's very hard to stop noticing.
Even this study suggests a similar idea, that disruptions to our body cause our hunger response to not work properly and this helps lead to people overeating because they feel the need for food even when it's not true.
