Susan Asbjornson Ziegler
39, opera singer
Hermosa Beach, California

What Did It: Once Ziegler—a veteran dieter (always gunning for the same 20 to 30 pounds)—signed her contract, she went to a nutritionist and brought home a new eating plan that added fat and protein to her diet and took away many of the carbohydrates. She also started working out four to five times a week, doing 30 minutes of cardio and 25 minutes of weights.
