Plot the rise of computer related desk jobs on a graph and then overlay that with the same graph for obesity. Obviously not the sole cause but they line up pretty nicely

You might try adding the number of McDonald's locations and their revenue. I have a hypothesis.

God, now I want a Big Mac.

Mask-wearing is like foot-binding and leeching. Pathological and perverse, perhaps. But also totally cool and in agreement with the experts. It's a window into our psychology. Anthropologists of the future will reap much research papers.

One of the sad things about the Internet these days is that into every conversation descends the Screaming Loonie™. The Screaming Loonie doesn't waste any time but immediately dives into some world-class conspiracy theory - in this case, "Almost all the world's doctors, medical researchers and public health officials are in a century-long conspiracy to present a false theory, that masks help prevent infectious respir…

That is a carefully roundabout argument for something, no doubt. And I'm sure that the experts all agree.

>bisphenol A mimics the hormone estrogen and can lead to damage in sperm development.19 Further research has shown that microplastics, and not just those with bisphenol A, can cause damage to the testes and lead to the production of deformed sperm cells that have a harder time reaching eggs. I'd more interested in hearing what microdosing xenestrogens on a large scale does to our collective psychology. I think this i…

It could explain the rise of trans women too. It's honestly quite frightening to think we are unknowingly modifying ourselves at such a scale.

I have to question that claim. Poor countries eat plastic two, yet we don’t see the same cultural phenomenon‘s here.

What’s worrying about this is that we’re about 50 years into an unexplained epidemic of obesity and metabolic disease that nobody has a clear explanation for, and is also affecting lab animals fed controlled diets. It would be fascinating if this was all correlated with a common environmental contaminant, and the increasing use of various plastics could line up well.

I don’t think it’s unexplained at all. People just don’t like the explanation. People simply eat too much and don’t move enough. The secondary reasons behind that are many but again pretty easy to see (more desk jobs, cheap high calorie foods, automobile ownership etc)

It's pretty clear the epidemic of obesity and metabolic disease is largely caused by sugar https://youtu.be/dBnniua6-oM

It’s not at all clear that the current epidemic is caused by sugar. Lustig is a great speaker, and I’ll admit that when I first watched that I was quite convinced. His position, however, is still not representative of a consensus within the field, and for good reason. While sugar consumption is likely detrimental to one’s overall health. Simply cutting out sugar is not necessarily going to lead to better weight manag…

Sure, simply cutting out sugar but otherwise making poor dietary choices isn't going to lead to weight loss. Cutting out sugar tends to make it easier to eat healthy, though. Long term weight loss requires lifestyle changes.

In my personal anecdotal experience, my weight gain and loss correlates to my caloric intake. When I've explicitly calorie counted, foods with refined carbohydrates are typically what blows up my count. When I've done low carb high fat and protein diets, I've found it difficult to eat too much, to the point of coming up several hundred calories short per day.

>> When it comes to eating microplastics, scientists have documented plastic particles in about 40 percent of the human diet, including beer, honey, salt, and seafood I was surprised about the honey. Geezz. Anyways, i've got about 35 fruit trees, and 90 berry bushes in the backyard and I plan to eat primarily from that as soon as they generate enough food..

AFAIK that probably won't help you much as rain also contains plastic particles, which is also why all bodies of water tested (so far), even underground, contain plastic.

we don't get rain 10 months of the year. Irrigate from city water.

do the fruit contain plastic?

You may find this exposition interesting: http://achemicalhunger.com/

This must be part of some disinformation effort to streer people away from the simple answer. Their conclusion is that you're helpless if your fat and that's just not true. The idea that this is not in your hands is ridiculous. If you are fat and you don't want to be fat you simply change your eating habits. This can be very difficult to do because you have formed these habits throughout your life but it isn't compli…

Obviously you [0] didn't read the article, but that is not their conclusion.

There seems to be some kind of unfortunate "shame brigade" out on the Internet that comes out of the woodwork to overrun any conversation around obesity that even hints that there might be reasons for the obesity epidemic other than individual people's poor choices.

The lab rats whose rate of obesity has increased over the last 30 years, despite consuming the exact same controlled diets, are certainly not "changing their eating habits" -- there must be more to the picture than merely eating habits.

This set of articles explores that. We don't have answers yet, but these folks make a strong argument that the question is worth asking.

[0] It's an unfortunate fact of scientific progress that ideologues have, in other fields, at other times, held back that scientific progress for decades through their inability to consider disconfirming evidence against a favored theory. This kind of comment should be ignored by anyone who values truth over consensus.

Most folks who respond like this are not looking for reasons to believe they might be wrong, but just in case you are, please take a look at A Chemical Hunger [0], which explores these questions in some depth.

It turns out, the simple explanations (people eat more & move less! too much sugar! etc.) are in fact insufficient.

Sugar consumption peaked in 1997 [0] in the US. Obesity continues to rise.

In Australia, sugar consumption dropped 23% (and other sweeteners dropped 16%) from 1980 to 2003, while obesity tripled. [1]

There is more to the picture.

I really, really recommend watching this lecture: The Human Microbiome: A New Frontier in Health by Susan Lynch https://www.youtube.com/watch?v=XCaTQzjX2rQ What food you eat certainly influences conditions in your gut, which influences your gut microbiome. On the other hand, your gut microbiome is highly persistent and even efforts to diet may not have the direct impact you'd think it would. Also, other factors (like…

Indeed, this was very interesting. However, I missed a bit what changes to my diet I could do to improve myicrobiome. I would be glad to hear a scientist like her discussing this.

This may not directly answer your question, but the Huberman Lab podcast [1] is done by a Stanford professor and generally includes very high quality summaries of recent research. He also provides actionable suggestions (though sometimes, the research is so new that they're still in the process of figuring this out). You can scroll through the home page and see the variety of topics he covers, there are a number on gut health.
