I understand many of these guys have healthy lifestyles outside of eating with a regular diet and exercise, hence it's easy to maintain a healthy weight.
However, when they consume up to 50x the recommended daily intake of sugar, or 20x the recommended salt intake as I've seen in some challenges, how do the kidneys/liver/heart not suffer overload?

My understanding is that they regurgitate (vomit) up the consumed food after the competition has ended. They also don't compete on a daily, or even weekly basis, for the most part.
