Japan is not like America in the sense that they do not tend to overeat.  I noticed that everything is smaller portions. If you order chicken and fries in Japan you probably will get about only 12 fries and little pieces of chicken. They are very health conscious that is why most of the Japanese are not obese.  Most are very slim and I can see why. Although at first I was disappointed in the smaller portions it helped me to be more conscious in what I was eating and taught me not to overeat. You would be surprised that the smaller portion actually made me more full than eating as much as I usually would. It took a little while to get used to the small portions but after being there for a week I knew what to expect when eating. I believe if America could cut back just a little bit then our people will be better off and there will be less health problems.
