There is an old saying "If you want something done right, you have to do it yourself"

I take that to heart. Including what I put in my body. I have little to no faith in modern food. And so I grow my own. I know where it came from and what went into it. And yes, I have had my soil tested.

Rely on modern food at your own peril. You are what you eat, as they say.

As an anecdotal experience, I have stopped eating any kind of commercial bread many years ago, despite the fact that I like bread. The reason was that I could not become satiated when eating commercial bread, before eating huge quantities, which filled me up. It is much easier for me to not start eating something than to stop after beginning to eat, so I gave up completely on eating bread. Nevertheless, I have starte…

It could also be that home made bread is chewier and so it takes longer to eat, or that it's a psychological effect from having made it yourself.

I do not think that there is any psychological reason, because I was very surprised by this, as it was contrary to my expectations.

However you are right that it is chewier than commercial bread and I have also thought that this may be an additional explanation. I believe that the longer chewing time contributes to the satiation effect, but it cannot explain all of it, as I remain satiated for many hours, and I do not believe that the extra chewing can have a lasting effect.

In any case the fact that most modern food requires much less chewing than traditional food is indeed a likely contributory factor to the tendency of eating more at a meal than it was common for the previous generations.

I do a lot of high school senior photography. It's hard to talk about this without sounding crude as a guy but something that I've noticed that contrasts with when I graduated high school (2006) is just how many girls have huge breasts. I think there were 2 girls in my grade that were skinny and had what would be called "large" breasts. Most other skinny girls had the standard A or B cups. Now a very large portion ha…

So the funny thing is I was hearing the same thing ( that the average cup size had increase to C) back when I graduated high school in the late 90s.

I think non anectodally, this trend is something that has been going on for a long time. If I remember correctly we blamed microplastics in the water minicking estrogen, and starting puberty earlier.

What is the truth is probably unknown.

Directly. It stimulates insulin release from the pacreas.

Eesh… that doesn’t seem great. How does this not cause further habituation?

Human and animal studies demonstrate that it doesn't seem to worsen insulin resistance if treatment is ceased, but probably doesn't significantly improve it either.

Yesterday, I had 3 bottles of coke at 40g of sugar each, 4 cups of OJ at 25g of sugar each, and 1/3 a pound of fudge, which I think is about 50g. That's around 270g of simple sugars. If you care about carb intake, I also had 7 idlis, which is an indian rice cake, and a dosa, which is a rice crepe, which probably adds a significant amount of starch. I probably reliably have 2x the average for simple sugars

May I ask if you're under 45?

Yes haha. I'm sure my habits will change as I age

My guess is that obesogens are to blame, but that they're in food, not plastics. This is because people on weirdo diets (vegans, carnivore, ultra low fat) all lose weight and keep it off, even when they are using the same amount of plastic as everyone else. The common denominator is that they stopped eating industrially manufactured food. I am no expert in the area, just wondering what the hell is going on.

> I find it incredibly sad that you could be that large already at that age. I can only imagine how difficult it would make life.

As someone about this size, but has also been relatively "fit" at this size (I used to be able to go on casual 10+ mile hikes on weekends, pre-pandemic), it's also our health system failing us. I've never had a doctor give me a better answer than "diet and exercise" to change things. I got to a level of fitness where I could go on 10 mile hikes, which is a hell of a lot more fit than a lot than many Americans, yet they'd still give me doom and gloom and uninterested answers. It's exhausting.

America does not treat obesity well, and I feel like there's not good enough research going into it. I love to see reporting like—and hope there's more to come, in hopes that it changes both clinical mindsets and also how we think about obesity. It's more than what you eat.

Blaming plastic seems incredibly strange to me, given that plastics are practically universally present in American life but obesity itself is not universal.

Did anyone say plastic is the only factor?

I mean, if we were confident one particular food source contributes more to obesity than others, we have a solution that we know would work: tax it (and ideally dedicate revenues to some kind of universal food tax credit). People would consume less of it at the margin and then be less obese. It would rankle some people, but so do taxes on alcohol and nicotine. My big concern is that I'm skeptical whether we can reall…

That's the solution everyone wants "identify bad food and tax/ban it" - but when apple juice has as much or more calories than soda, what do you do? A per-calorie tax might work if you rebated it correctly, but the mechanics of that would be insane. Perhaps it could be tied to basic income - we will tax calories at ten cents per calorie, and give each person 2000 calories (200$) a day ...

That's interesting. A large side of fries at Macdonald's would be $50 (though I suppose everything else would also jump a lot in price). Definitely creates a strong incentive to consume less.

Implementation wise, it probably would be best to begin at something like half a cent per calorie and then ratchet it up until we hit some target number (or until we discover it doesn't actually influence behavior). Then at the end of the year people get a $4000 dollar tax credit.

> but there's nothing changing our metabolism. Why would you be so confident when we know for a fact that hormone imbalances can absolutely impact our metabolism. Including signaling to your body to produce and store more fat than it normally would. Cortisol the hormone produced in stress responses is shown to do exactly that. Using yourself as an anecdote isn't useful in anyway.

Matter isn't created out of thin air.

That was never the claim. Nice attempt at a straw man though. You seem to be under the impression that body fat only accumulates in scenarios with excess calories. That's explicitly wrong. What some of these metabolic disorders do is prioritize the accumulation of fat from calories over sustaining other parts of the body. There are multiple ways that your body converts calories into energy, and they can be thrown off by hormones. Some metabolic conditions, like Cushings, overstimulates the production of body fat starving the muscles of energy so they atrophy.

To put it in clearer terms, you could take two people of identical sex, height and weight and feed them the exact same diet with the exact same exercise routine and still have one pack on more body fat due to hormonal issues impacting how they metabolize food. Telling the person who's gaining fat to just eat less isn't helpful or healthy. They need to address the condition causing the additional body fat accumulation and it's not excess calories.

To be perfectly clear, I'm not suggesting that this is the case with microplastics. I don't think we have the research to determine that yet. I'm merely disputing the inane "just eat less bro" nonsense that tends to crop up in these threads.
