"MasterChef" judge Graham Elliot announced on Twitter he has lost 128 pounds thanks to a sleeve gastrectomy he underwent in July. Elliot, 36, tweeted before-and-after photos of himself Wednesday, along with a message saying he now weighs 268 pounds. "Weight loss update: now weighing in at 268lbs, down from 396lbs. Thanks everyone for the continued support!" he tweeted. The Los Angeles Times said Elliot regularly tweets photos of his new exercise routines and noted he finished a 5K race with his wife, Allie, in November.
