Obesity Epidemic Causes

Possible, but I would tend to bet its just a high sugar and sweetener diet more than anything. Obesity is not uniform at all. In pre covid days of seeing many people, I would rarely see anyone who is obese (northeast american), but that's because I'm in an upper middle class bubble. These days I'm pretty good about avoiding heating up plastics and what not. Growing up it wasn't on our radar at all. Point I'm trying to make is plastic exposure is pretty high for all popul

I'd bet on the underlying factor being nutrition. Processed foods, sugar substitutes, and forever chemicals in everything to an extent earlier generations never saw.But that's a wild guess.

Our food chain has a lot to do with obesity. There are many studies on this stuff.We eat 5 times as much meat on average as people did 100 years go. Animal based products are a major source of fat. People used to eat more fruits and vegetables. The fat type has shifted with more fat (which has higher calorie per gram amounts than carbs or protein) and fat moving from polyunsaturated fats to saturated fats (which causes lots of medical problems).In there is the growth hormone. Kids "ma

I don't know about this, there's a lot of factors listed individually here but not in comnination. It could be something like "eats lots of sugar and doesn't move", like are those honey and starch eaters as sedentary as us?Then again, it woildn't totally surprise me if it were something like indoor lighting or something.Edit: The second article accounts for some combinatiins but not to my satisfaction.

It's an intriguing question! People of the early 20th century ate too much fat, too much sugar, too many carbs, too many calories, and yet did not grow obese. There is an interesting paper [1] making a strong case that the cause of the 21st century obesity epidemic is an unidentified environmental contaminant which (1) causes obesity in both humans and other mammals; (2) accumulates in major river valleys; (3) started noticeably affecting the US around 1980, and by now has spread worldwide.

Its the same with obesity, which has been sharply increasing in much of the world since the 1970s, but pretty much all the conventional explanations (increased availability, excess sugar, excess carbs, excess fat, decreased physical activity, etc.) don't seem to stand up to scrutiny.Hypothesis: the cause in both cases is likely industrial contaminants considered essential to the running of modern civilization, so nobody wants to, or is encouraged not to, look too hard.

That's one possible cause. It could also be that our diets have changed to make us more prone to obesity, perhaps people consume more processed foods than before. The article alludes to this when it says eating badly is a major cause of obesity.I don't think there is enough information quite yet to jump to the positive conclusion of greater abundance causing obesity.

Sounds like an edge case. Very high rate of obesity, massive sugar consumption, and lack of outdoor exposure are probably doing a number on people.

| The likely reason is the changes in lifestyleAgreed, that's the commonly held reason but when one attempts to reverse what the changes seem to have been, by exercising more and eating less, that doesn't seem to work. My point is that perhaps we need to better understand what the changes have been, that perhaps they are more subtle than they are commonly held to be.

To summarize, populations who diet and exercise, the same amount as populations in the 80s, are heavier. No one knows why, but some possibilities are- increases in chemicals in the environment- increased prescription drug use- increases in animal product consumption- changes in the human gut biome- proliferation of artificial sweeteners
