I like that in Japan the idea is not “get as much as you can worth your money” but instead “get exactly what you are gonna consume and not waste food”, it’s beautiful actually.

@GeorgeP-uj8xc

A huge component is also WALKABILITY. Even Japanese suburbs are made to be pedestrian first and car second.

@kray97

1. Healthier options at 7-11
2. Less sugar in most processed foods
3. Portion control built into serving sizes

@Whataboutbob-b4w

America: quantity over quality
Japan: quality over quantity

@glissemaster

A friend who just returned from Japan said people don't consume their food or beverages on the go. If you order food, you stand there and eat it, then give the dish back. Or at Starbucks, she had to drink the whole coffee before she left. This might be one of the reasons the portion sizes for food and beverages are smaller.

@Ziggy9000

Two months in Japan and my gut histamine issues cleared up. No runny nose from eating and my anhedonia and brain fog was lifting more and more. Then I came back to the US and got severe food poisoning and months later still feeling worse than before I left for Japan. I'm planning on moving to Japan partly for health reasons. The food was healing me.

@oldschoolgreentube

In Japan I walked EVERYWHERE!  If I wanted to eat some KFC or McD's, I'd have to walk about a 1/4 mile to get it.  Grocery shopping.  I walked there, and carried my groceries home.
I walked to the train station, from the train station I walked to the bus station, from the bus station I walked to work. Coming home I did it all in reverse.  5 to 7 times a week.
When I went out in the evening to a bar or club, I walked.
Walk, walk, walk, walk.  Everywhere.
In the US, I sit.  I sit in my car to go to work.  I sit at work. I sit when I go out. Daily walking distance are measured in yards. In Japan I walked miles daily.

@leagueestates

I've always been overweight in the US, but after just 3 months living in Japan, I lost over 30lbs without dieting, just ate whatever I wanted.

@jlanderson21257

When my daughter in law, who is born and raised in Korea, brought her family over to stay with me in the States for the first time, I made a big breakfast, and also had donuts.  I could tell her relatives were so confused.  Not only too much food, but the donuts were the most confusing part.  My daughter in law said, that while they have seen them before, they only saw them as some sort of desert after a dinner.  It was like I was giving them a birthday cake as breakfast.  By the time her family left, I completely changed my way of eating meals, beginning with breakfast!

@SuperJacques96

I think the biggest factors are:
1. Foods are not highly processed or filled with sugar.
2. Japan is very walkable with the exception of remote towns.

@BernhardWelzel

Biggest point is missing: social pressure. being overweight is not accepted in Japan. 

Update 30.05. I also wrote "Some employees have contracts that enforce yearly checkups and overweight = risk to your job. " - His seemed to be an oversimplification by me. Thank you all for helping me to learn more about this topic!

@mhyc1962

FATPHOBIA. I’m a Japanese woman. I agree that there’s healthier choices available in Japan but there’s a large aspect of social pressure that plays a role. People’s appearance is an extremely common topic in our daily lives. Gen Z and alpha say “デブとブスに人権は無い” “the fat and ugly are no humans.” With the accelerated exposure to social media, the younger generation especially, are hyperaware of their appearance and ED is unfortunately so common that it’s not talked enough. Some people are sacrificing their health to stay skinny

@hayatejohnny

I am Japanese. What you are saying makes sense, but people in Japan are not necessarily health because they look skinny on average, hardly anyone I know does any active physical activity besides walking. You can see it in the elderly in the way they walk, they start looking almost like robots-- weak joints and not a lot of muscle.
I would also like to emphasize the fact that in the last 10 years I've seen a very noticeable increase in my area of people who are definitely overweight, and many who are straight up obese, in my area of Saitama (prefecture adjacent to Tokyo). Whereas 10 years ago you would be hard pressed to even see anyone overweight, nowadays it seems like the norm, especially in younger people-- many lower class working folks have a diet that practically only consists of cheap, high calorie fast foods like ramen bowls. 
 
Japan, is definitely on a similar, slowly engorging path as other western countries, just not at the same speed. Just because half of the population in the US is morbidly obese (hyperbole), doesn't mean overweight people in other countries should be considered "skinny".

@VarsVerum

The first video I saw on this channel was on why everyone in Japan is so thin. Can't believe it's been almost 8 years since then.

@ainternet239

One thing that struck me, a European, when I visited the US on a business trip in the 1990s: the hotel I was in served me more food at breakfast than I usually ate in an entire day

@NombreApellido-mz6xn

Honestly, as a European, this isn't about US vs Japan as much as US vs the rest of the world.

@peterfmodel

When I worked in Tokyo my office in Yoga was next door to a girls high school and a lot of the girls were overweight. But in my office no one was overweight. I asked one of my female co-workers about this and she said at high school most girls spent all their time studying and eating. When they graduate and go to work they go on a diet to get their weight down. It should also be noted that being overweight is regarded as a health issue.

@j_lemy

1. People walk a lot.
2. People work a lot.
3. Minimally processed and healthy food is everywhere.

@nobukazumikami5466

I am Japanese. I moved to US over 20 years ago. I do not necessarily agree that many Japanese are not fat. They look slim, but could be skinny-fat. They commute with walking, biking, public transportations, but they do not do full body exercises in regular basis. I became more fitness-oriented after moving to US because gyms are everywhere and easily accessible.

@ThePColl2k

While studying abroad in Japan, I passively lost weight even while eating out basically every day. By the time I came back to the US, I had lost over 20 pounds. After moving back, it's been a struggle to maintain and prevent my weight from rising back up again. The fatness of the US is endemic.
