Many kids of the world said, "Why do American people are so fat? Eating to much?

Today's my story is very serious not only U.S. but also all counties of the world.
Listen to me carefully.
When kids from overseas visit U.S. they are so surprised.
Because many fat people walk in the street many cities in U.S.
Some kids said to me, "Did they eat so much everyday as elephants?
I can't answer.
From now fat people will increase so much absolutely.
This phenomenon increase many countries from now.
People of the world must know that fat is very dangerous.
