New York Post, June 11, 2012 Cindy Adams. IN September Hubert Hughes, Anguilla’s chief minister, is organizing a 21-day blubber’s biggest loser shrink on his island. It’s together with James Hester and Roni DeLuz’s best seller “21 Pounds in 21 Days: The Martha’s Vineyard Diet Detox.” Here for Caribbean week, the minister was feted. One of the feters was Bravo’s Chef Roble, whose own fete was cooking for B.O. in the White House.
