Drew Carey has dropped a reported 70 lbs. -- and he tells he couldn't feel better.

"I just got sick of being fat," he told Us Wednesday at the 2010 CBS Summer Press Tour Party in Beverly Hills.

In early May, the National Enquirer reported that The Price Is Right host, 52, was dieting and working out. A month later, it claimed Carey was using an "custom-made appetite suppressant administered by a Hollywood nutritionist."

But Carey told Us he's been following a cardio program, "so there's nobody really standing over me. I do work with somebody who gives me advice on what to do, how many minutes to run, what my heart rate should be and all that kind of stuff."

Carey, who said he is no longer diabetic, told Us he wants to lose more weight "so I can be looking that great at 86."

Added the actor, "My fiancee has a 5-year old, and wow, I'd love to see him graduate. I'd love to be able play with him without getting tired, enjoy my life and watch him grow."

Though he still eats meat, he told Us he has one strict food rule: "No donuts!"
