As per Modelinia:
Chanel Iman on the other hand, focused on gaining weight for the show. “I’m always the opposite of everything,” Chanel told us during her fitting last week. Having already gained 15 pounds, Chanel’s been working hard to keep the weight on. “I drink a lot of protein shakes and do a lot of weight lifting,” she said. And the day before the Fashion Show? “I have a big potluck at my house. All my friends bring over food and we barbecue and party it up!”
This sounds way more fun than a powdered egg fast.
