The 47-year-old actress maintains her overall health and fitness as she abides by a clean diet plan. Most of the time, she focuses on eating unprocessed and well-rounded foods. She does so not only for keeping her body in top shape but also for feeling great from the inside out. As an actress, her diet can also be affected by the roles she plays. Sometimes, she needs to lose more weight and there are also instances when she’s required to gain some pounds. For her role on Mad Men, however, the actress wasn’t required to do any dieting. She was able to keep her figure the way it was. “I felt I could eat as many M&Ms as I wanted,” she said.
