Ok so I was watching the national geo channel and sumo wrestelers do the same thing and the crazy thing is that they are very healthy they get up in the morning and train for upwards of 10 hours before they even eat and starting at about 5 or 6 in the pm they start eating everything in site all the way up until they sleep.... the rational behind this is that all of the fat they put on is surface fat there organs and blood remain relativley untouched by fat that is how thay remain in good health and have decent cardio..... now as for bodybuilding who knows it may work for some! sumo guys are not lifting weighs if they were maybe alot of what they put on would be muscle hope I did not get too far off topic I just thought it was interesting.
