Cristiane ‘Cyborg’ Justino put on over a stone just hours after her weigh-in

We're not doctors, but we reckon that putting on this kind of weight can't be good for you.

Cristiane Justino - better known as Cyborg - has showed the frightening extremities of weight-cutting with how much she has regained in under a day. The Brazilian is defending her featherweight title at Invicta FC 15 on Saturday night but since the weigh-ins she has put on so much weight again that she's almost a man's welterweight. Cyborg weighed in at 145lbs. 18 hours later, she's over 163lbs according to her boyfriend's Instagram post. That's 18lbs in 18 hours. That's a pound an hour. And, when she's finished with Daria Ibragimova, Cyborg wants a shot at Holly Holm. But not at 135 lbs. At catchweight. "Superfight? Yeah. I think that's fair," she told MMA Fighting. "Somebody can go up a little bit, I'll go down a little bit. She's [Holly Holm] the champ and if she says she wants fight me, then we can fight. I think it's good for women's MMA if we can fight. She knows I cannot go to 135, it's too hard."
