Former World Heavyweight Champion Mark Herny was last seen on WWE TV at Survivor Series 2014 PPV where he was the first person to be eliminated from the main event match after a knockout punch from Big Show.
Henry took a hiatus from WWE after that match due to an unspecified injury. With his return still in question, Mark Henry has lost a lot of weight since the last time we saw him on TV.
In the past, we would never think about losing weight as that would be directly proportional to decrease in strength. Due to his “strongest man in the world” mentality, it would ultimately hinder his ability to keep the weight off.
