Kelly Osbourne's secret to losing 60 pounds and keeping it off has reportedly been the plate diet. There are studies that suggest when food is served on plates that are different colors than the meal, people will eat up to 20% less. Osbourne has apparently been following this rule and it seems like it is working. 
"Five months after Kelly started the plan the results are there for all to see," a source said. "Unlike other fads, Kelly says this diet really does help you lose weight and keep it off."
