Gluttony is suggested to be one of the seven deadly sins and it has led to the death of many. Ironically, despite obesity being a leading cause of preventable death in the world, many still strive to become the ultimate glutton with competitive eating contests growing in popularity and people making nearly six figures annually by allowing fans to watch them eat.
