Curious? I thought this was a great way to highlight what not to do!
There are some specific ways the sumo diet causes ordinary people to gain extraordinary amounts of weight. The first is that sumo wrestlers never eat breakfast. They wake up, and the first thing they do is start exercising vigorously.
This combination of skipping breakfast and then training really hard for 5 hours means that by the time they get to eat, they are starving.
As a consequence, they overeat -- they eat much more food than they need to feel full.
Sumo wrestlers go to sleep almost immediately after they eat. Sleeping immediately after you eat is a sure way to pile on the pounds. The body slows down its metabolism during sleep, and any undigested food left in your system is stored for later use, usually as fat.

Take-home lesson for those of us definitely NOT interested in building a sumo physique?
Eat your breakfast!
Spread your food intake and calories throughout the day.
Wait at least 2 to 3 hours after your last meal before going to sleep.
