Size and structure
It is likely that people in other countries do not have the problems that we do with overeating because of two things—size and structure. Their kitchens and pantries are not as big as ours. They do not drive SUVs big enough to transport the mass quantities of food we purchase at warehouse clubs. They often do not drive at all, so they have to haul their purchases home in their arms. We also eat everywhere and at different times throughout the day. In other countries, people eat three meals each day, and they eat in the kitchen and at the table. Unfortunately, other countries are starting to catch up to us now.
