I think it's easy for the guys to slip back because society doesn't put pressure on them to maintain a "slim" figure. Shame Erik had to win the show before gaining weight, he could have just gained the weight during the time home and allowed Kaigoddess to win (<333!)

I think Ali is going to be the cover story for this show for years to come. I don't see her gaining back the weight. That woman has hella amount of discipline and determination. Plus, she works for the show now so I don't see them letting her gain weight back.
