One of the most striking things about my trip to Japan was how thin everyone was. I kept saying to my family, “There are no fat Japanese!”

That’s not entirely true, of course. Aside from sumo wrestlers, there are some Japanese people who are fat — but at least in my two-week trip to Tokyo, they were pretty hard to find.

Seriously: in America (including my hometown of Guam), you could walk around and half if not most of the people you see will be at least a little overweight. Many are outright obese. But in Japan, everyone is thin it seems. I could go a whole day without seeing a fat person, unless it was a tourist.

This is not groundbreaking news, I know — it’s long been known that the Japanese are among the healthiest people on Earth, with one of the lowest rates of obesity among developed nations and one of the longest average lifespans. But when you actually see it in person, it’s almost shocking.

During my stay in Japan, I formed some theories — and these won’t be groundbreaking either, but I think they’re worth reflecting on. Be aware, of course, that I’m not an expert in any related field here, and my observations are based on a two-week stay in Tokyo, and therefore are very, very limited. But here are the reasons the Japanese are not fat, in my opinion:

1. They eat a lot of seafood and veggies. It’s true that they eat red meat, and sometimes it’s fried. But red meat or poultry doesn’t seem to be the main staple of their diet as much as seafood, rice and veggies are. Meat seems to be eaten in smaller amounts (usually as a seasoning, not a main dish), or if it’s eaten in bigger amounts, it’s not an everyday occurrence. This is a generalization, of course, as is everything in this article, so there are many exceptions. Not everyone in Japan eats the same way. » Continue your journey »
