The idea you cant be poor and obese at the same time holds hard, but clearly the nutrition at the bottom of the pile is worse than it used to be

Common industry trope - same with climate change EVs vs industrial processes. We keep asking 7.9 billion people to attack the 5% or less left of an issue that maybe they with full collective action could dent, while just pretending that nothing can be done by the IDK 100,000 people running the industrial processes responsible for like 70% of the problem.

I swear, it's the latte / avocado toast financial advice. Yes, if I drop $100-$200 a month habit it'll make up for the $4,000 a month unsustainable living expenses.

What. No. We drive far more, and have more cars. In 1960 nearly a quarter of households didn't even have a car. Now that is only 10%.

Here is a study on occupational movement, which has decreased significantly (100 kcal a day - which is roughly a pound bodyweight energy lost per month).

In addition, people had far more incidental and leisure movement - considering that hours of TV watched nearly doubled.

Of course, our trash diet is a huge aspect, and probably the lions share - but the lack of movement is not insignificant

Partially right on the food but absolutely wrong on lifestyle changes over the last few decades. Specifically we are talking youth here, in western countries but evidence also supports places like China with more and more youth neglecting exercise and sports to stay inside and consume digital entertainment instead that only compounds with increasingly unhealthy dietary choices. Increasing sugar and carb intake while neglecting other nutrients and vitamins. Both factors are bad on their own but the effect is multiplicitive when combined. And a third factor with the subculture pushing obese acceptance and trying to present overweight people as being just as healthy as those pursuing atheltic and active lifestyles makes people who have fallen into the trap of sedentary lifestyle eating unhealthy foods regularly even less likely to try and change and improve themself, many people giving up cause its hard to break free of something they know and gives them comfort, even if its literally killing them slowly.

Its both. In developed countries kids are playing Fortnite, watching streamers on Twitch etc. and pinging their friends on social media vs. every decade up until the early 2000s, where kids essentially went outside all day anytime they weren't in school. In the US, dozens of dietary factors are also to blame. Subsidized corn, poor nutrition education, ubiquity of fast food and fast casual restaurants, snack food marketing around social events like holidays and the Super Bowl, advent of food delivery apps, growth of the "body positivity" movement etc. are all reasons people have trended toward obesity.

Do you have any sources whatsoever or are you just making stuff up because you just dislike "they".

Of course people didn't have to watch their intake as much earlier. Food is unhealthier and more plentiful than ever.

Btw, why shouldn't "they" blame you? It's your own damn body. Of course the industry should be regulated more but that also applies to every industry.

I'm clearly not in this article (about the increase in obesity rates since 1990s) because I've been obese since the 80s.

Yeah based on BMI, when I was eating healthy, active, AND young enough to easily shed weight I was still considered obese. Feels bad man.
