When Carrie Fisher announced that she would be the latest celebrity to lose weight by endorsing Jenny Craig, the dieting company should have been counting their blessings (and their future dividends).

Fat is big business in Hollywood. Our country's obsession with fat has helped to fuel a $40 billion diet industry that churns out diet supplements, self-help books, weight-management programs and fitness centers. At the heart of that diet industry is the celebrity endorsement, deals that have paid out anywhere from $500,000 to $5 million a year for celebrities like Kirstie Alley, Marie Osmond, Jennifer Hudson and Valerie Bertinelli, who are all willing to publicly lose weight.

The proof of financial gains is in J-Hud's fat-free pudding.
