Everyone blames food/diet/portions for this, but personally I think the car-centric culture should also bear a large portion of the blame.
When I stayed with friends in Europe, they easily ate as much as my American friends, but everywhere we went we were either walking or biking.
Meanwhile, in the VAST majority of the US, if you so much as want a safe place to walk that isn't adjacent to the pervasive pedestrian-hostile street design, you need to take a car to get there.
American car culture essentially turns the average routine into ferrying oneself from chair to desk to chair to bed, intermixed with brief walks throgh scenic parking lots.
We need to counter the sedentary lifestyle within the design of our actual cities, but its the american way to push societal problems onto the responsibility of the individual... so I do not see this changing within our lifetimes.
Sure, that may be true although I'd push back on your assertion that people somehow won't notice they've added 100lbs unless they walk everywhere.
The main issue is that processed foods are very high in calories and low in everything that is good for you and these foods are absolutely everywhere in the US. Work meetings frequently have a box of donuts on the table (700 calories each) huge sodas are common, coffees are more like a dessert than a drink, etc.
According to my watch if I do a 15 minute walk with some light jogging that's around 120 calories. I'd have to do that twice to cancel out a single can of soda.
Yes maybe 'notice' 100lbs gain is a strong word, but you don't fully realize it until you actually start wheezing doing something you used to consider normal. If your only exercise is walking from the car to your desk job and back you may just chalk it down to being a little out of shape.

Definitely, that is the main issue. I'm just saying the benefts (even just the weigh-control benefits) of walking are more than the calories spent.
Walking is a very low intensity exercise that will not burn a lot of calories, but is it's the only exercise you get it's a whole lot better than nothing.
I thought humans were notoriously efficient walkers, so we don’t burn that many calories that way?
The problem is partly the culture, but largely the design of our suburbs and sprawl.
Increased density and public transit are cool, but until there’s laws about not cutting down that “empty” patch of trees, or paving over that old farmland, developers are gonna make shitty sprawl, and cars will be necessary.
I mean it’s so bad and people are so cheap about it that they choose forced HOAs to maintain culdesacs and roads instead of properly funding public services with taxes.
How fast do you think weight is gained or how long do you think people spend in cars that gaining an excessive amount of weight is a surprise? No arguments about walking being healthier, but for most people, time in the car isn't that significant.
If, in your whole day, you never walk more than 100 meters at a time (likely, if you go by car everywhere) you may not notice the weight gain for years.
If you live in a place with an elevator or on the ground floor, get your food delivered or get it at a drive-in, do most of your shopping online, go to places with parking lots, where you just walk maybe 20-30 meters before you sit down, you'll not notice your health is going to shit.
As someone that lives in the world you're describing and drives everywhere, you're wrong. Weight doesn't just all of the sudden exist. Walking 40ft instead of 300ft twice a day is not going to make a noticeable difference. Again walking is healthier, but nobody has ever driven, gotten really fat, and then wondered what happened.

No but walking 1 km from/to the station or going by bike certainly is. As is walking during holidays or whatnot.
Most people who gain weight do realize it by feeling it rather than by looking at the mirror, especially since it is a very slow process. If you feel the struggle walking 300 feet and you don't have other issues, you've probably gained a lot of weight already.
My guy, people in Europe who walk aren't walking 300ft in a day, they are walking probably 2-3km daily, those are the kinds of distance where you would start to really feel the effect of having gained 30-40 pounds that you might not realize if you walk like 300 ft in a day
You need 1500 calories daily for brain stuff, breathing, liver, etc. You probably need only 500 it so calories to feed your muscles throughout the day. Being thin starts with eating, not with exercise.
