#1 Jennifer Lopez
A woman of multiple talents, at 45, Jennifer Lopez oozes the benefits of an incredibly healthy lifestyle. Originally a dancer, she keeps fit with regular exercise and seven months after giving birth to twins in 2008, she completed a triathlon. At school she is said to have excelled in athletics (specifically in national track championships), rather than schoolwork. She says her diet is simply balanced and that she eats in moderation. She doesn’t smoke or drink alcohol.
