Obesity is caused by eating too much. If you don’t eat then you won’t gain weight, there is no subverting the laws of thermodynamics. It sounds callous but if you go to Africa or visit a prisoner of war camp you won’t find many fat people and so blaming chemicals in America for so many fat people doesn’t make much sense to me.

Your argument is that forcing people to go without food causes them to lose weight, which is impossible to deny. You argument says nothing about what causes people to gain weight, however. Just look up 'hormonal weight gain' to see that it isn't just about eating less. Then look at research into the influence of chemicals/micro plastics on those hormones. Yes, all calories have to go in through the mouth. How those c…

>How those calories are processed, however, is influenced by a great many factors.

I feel compelled to assume that we can't possibly be extracting every calorie from certain types of food. Caloriometers work differently from human digestive systems.

True in the technical sense, but it doesn’t address the mystery that in the 40s, 50s, 60s people in rich countries had access to plenty of food, ate lots of calories, and yet obesity was very rare.

Nicotine suppresses appetite.

Trite, but accurate. I gained 50 lbs within 6 months after I quit smoking, when I had been skinny for decades prior. There is no doubt in my mind that the (justifiable) demonization of smoking in recent decades contributed to the obesity crisis.

Also the metabolic syndrome/obesity epidemic. 40% of US adults have obesity. By 2030 about half of US adults will, and in 29 states more than half of adults will be obese. We see obesity becoming increasingly normalized. People feel powerless to stop it and that we should just accept it. It feels to me like there is something besides diet changes happening to us. That's part of it, but I wonder if microplastics or so…

Obesity is caused in part by environmental toxins, probably to different extents in different people: https://www.theguardian.com/environment/2022/may/19/environm... https://www.webmd.com/obesity/what-to-know-obesogens These so called "obesogens" just increase the propensity towards obesity and depending on exposure and your sensitivity to then, you can overcome them or not via exercise and dieting and other means.

If it's environmental pollutants, shouldn't lab or wild animals be getting fatter as well? Yet they're not: https://www.lesswrong.com/posts/NRrbJJWnaSorrqvtZ/on-not-get...

This is the third time this week I've seen a study related to microplastics. Should I be alarmed? If so, what can I even do? If I'm understanding these studies correctly, these microplastics are everywhere. In our bodies, in our water supplies, in our food. And we can't even get rid of them.

I've started donating blood and eating cabbage regularly on the story that those things are good at getting crap out of the system and good for me otherwise anyway.

This was an idea of the infamous Romanian communist dictator Ceausescu: he wanted to feed the whole of Bucharest in a single giant canteen. Unfortunately he was toppled and killed in 1989 before this idea could come to fruition.

It’s unfortunate that a communist dictator was toppled and killed? Did you ever bother to look into why that happened and all the evils he did? We shouldn’t be borrowing from a dead communist dictator’s playbook. Clearly it didn’t work out for him and the vast majority of people didn’t want that.

I suspect the 'unfortunate' in the parent comment was dry irony, not an earnest expression of sadness.

In an environment awash with cheap calories, some people get obese and some don't. That's something worth investigating. (I personally think it's more about natural mental variation than subtle chemical poisoning, but that's probably just my bias talking).

Also the big elephant in the room is most people are hardly active. Your body is designed to forage for miles a day. Who even bothers simulating that? We walk to the fridge and from grocery store to parked car at most. Its so much easier to maintain good health if you are active.

I wonder how much better it would be if we had developed more for walking than for cars.

This will make you end up missing crucial trace elements if not replaced somehow

This is untrue, do the math on tap water compared to food. It's such a small contribution. >Using an average calcium concentration in public water supplies of 26 mg/liter and a maximum of 145 mg/liter (Durfor and Becker, 1964) and assuming that the average adult drinks 2 liters of this water daily, then the drinking water could contribute an average of 52 mg/day and a maximum of 290 mg/day. On an average basis this w…

I actually had a Vevor water distiller (still have it, actually) and drank almost exclusively distilled water for ~10months, ending June 2023.

I feel better going back on tap water, fewer stomach issues. I don't have a proper theory that can explain why this is the case, but it's certainly the case.

From the actual paper: "With this in mind, an in vivo study was designed to determine the effects of these MPs [microplastics] in a rodent model (Figure 2A). Following a 3-week exposure to PS-MPs, C57BL/6J mice were tested in a series of behavioral assays including the open-field and light–dark preference tests. Both assays showed significant changes in parameters such as distance traveled, rearing activity, and dura…

Good thing you’re not a mouse.

true, but this does make it seem more probable that microplastics could alter human behavior as well :)

I live in a country where, despite 70% water (I know, seawater) and lots of rainforests, most urban people drink bottled water (single-use and refills). Talk about selling ice to Eskimos. Probably because the ice outside is polluted, and it's easier to buy instead of fixing the root cause. Anyway, ignoring the effect on nature since we clearly don't care about it, how damaging would the effect be to people who consum…

bottled water actually has more microplastics than tap water (although both have some).
