I've dropped about 20 kg since moving to Japan myself. I was hungry for my first few months here. But I got used to it and I'm glad I can't eat like I did before. The Japanese diet is changing and it's getting less and less healthy. I see a lot of little kids that are real porkers. I guess the bright side of that is they'll have a larger pool of potention sumo wrestlers to choose from
. But the amount of obese people in the US is shocking if you've been away for awhile.
