Devoid of variation

Most Ethiopians eat pretty much the same thing day in and day out: injera (flatbread) and wat (stew). When my colleague S was in Ethiopia some 30 years ago as a volunteer, he was stationed out in the countryside for extended periods of time. He said he had no choice but to eat doro wat (chicken stew loaded with copped onion and spices) and injera for breakfast, lunch and dinner; that was simply all everyone ate. They would make a big pot of doro wat and then simply re-heat it for days until it was gone... and then likely just make it again. Thus, S suggests that Ethiopians generally stay thin because there is very little urge to overeat when you are eating the same thing all the time.
