Summary
A new Lancet study reveals nearly three-quarters of U.S. adults are overweight or obese, a sharp rise from just over half in 1990.
Obesity among adults doubled to over 40%, while rates among girls and women aged 15–24 nearly tripled to 29%.
The study highlights significant health risks, including diabetes, heart disease, and shortened life expectancy, alongside projected medical costs of up to $9.1 trillion over the next decade.
Experts stress obesity’s complex causes—genetic, environmental, and social—and call for structural reforms like food subsidies, taxes on sugary drinks, and expanded treatment access.
I took it to mean that they didn’t go out of their way to walk more, it was simply the better option to get around and so they just did that instead of driving a car. After moving from a car-centric city to one with a metro I totally get it and I do go for walks just for fun.
It’s not just about whether or not you can do something but about how available that thing is. Going for a walk can suck real bad in North America, surprisingly. Things like shitty food being the cheaper option, in a country racing to get its working class to be as disproportionately impoverished as possible, can make it hard to justify getting better quality stuff, too.
Yea it sucks walking next to 6 lanes of high speed traffic and basically no noise restrictions on cars. Once I moved somewhere that I could walk to the grocery store down quiet, tree lined streets most of the way, it became my preferred way. The built environment influences how you travel a lot.
The problem with the car thing is that there is noise reduction on cars. It’s the tires that are making most of the noise you hear from regular cars so even electric vehicles will make more noise than you’d think. It’s always wild to me that my aftermarket muffler isn’t as huge a difference in disruption as you’d think(it’s also not a high-pitch, obnoxious one). Either way I still keep it quiet at night or near pedestrians, and where I live now I’m glad that I basically never need to drive.
I’m real happy to hear that you live somewhere much more compatible with being a human being!
Yes, but there is also little enforcement on extremely loud exhausts and excessive engine revving. People should not be subject to noises loud enough to require hearing protection on a regular basis. Some studies are also finding that car noises in general generate stress responses in humans and long term exposure inreases the chance of some health conditions.
You could also argue road speed and road design should factor in to a noise reduction plan at a city planning level. Cities could enforce lower speeds in certain areas to reduce noise. If the city insists on funneling cars in a certain area they could also be responsible to install sound barriers, maybe even a thin tree line to help buffer noise near residential or certain commerical areas.
Absolutely, though as someone who notices louder exhausts I gotta say that, as much as they stand out, they’re really quite rare. It’s the never-ending drone of tires on pavement, loud cooling fans, heavy diesel trucks, and whatever other clattering and clanging that make up the bulk of the noise. The main street where I live goes pedestrian in the summer and I remember just how much noise a late-ish model Honda Civic made as it drove across it slowly one day even though it’s engine was essentially silent. The contrast between the peaceful pedestrian street and this single, “very quiet” sedan was startling. I already had sorta known but that moment is really where I decided that there’s no such as thing as a “quiet” car.
Our school busses have gone electric, though, and city busses are rapidly being replaced with hybrids that are quiet when they sit or need to accelerate. Those have reduced a lot of noise, and that’s super nice, but again they’re not the bulk of the noise. Removing the worst offenders but keeping the “quiet” cars doesn’t actually help beyond making us feel like we did something. We gotta start making main, commercial streets pedestrian only year-round. We gotta start being aggressive about making public transit accessible. We gotta start building on a human scale.
Indeed that’s what I meant, no intentional going for walks, just organically more walking as taking the train and walking is more convenient than driving almost every time.
