Do all Japanese actually eat that healthy? I can believe it of some of them, but there’s little fruit and many salarymen seem to live on a diet of fried chicken, hard liquor and cigarettes.
That's what surprised me the most visiting Japan. All the skinny people in Japan eating fried chicken, fried mashed potatoes, fried everything.
The only thing I could make out for why they were skinny was insane levels of portion control. Since they definitely didn't have time to do sports.
When you say they seem to live off this diet, what are you basing that on?
