Many people worship breakfast. They believe it is the most important meal of the day, and that skipping it causes various problems, such as fatigue, inefficiency at work and poor academic achievement in children.

Recently, however, some medical doctors have started questioning the breakfast faith. In some recently published books on diet, they assert that breakfast is not an indispensable meal for adults, and even recommend skipping it.

Shingo Kazemoto, a doctor at Yotsuya Medical Salon and author of "Atarashiku Umarekawaru Chiteki Diet (The New You Intelligent Diet)," says a conventional diet is not practical for people today.
