Jenna Jameson — Age 47

As a former adult entertainer, Jenna Jameson banked on her looks to become a star. But despite her living a quieter life in Hawaii, it’s evident that she still puts a lot of effort into taking care of herself. The AVN Hall of Fame inductee has been open about her weight loss journey, for example.

According to Delish, Jameson keeps her figure in check through the keto diet and even lost 80 pounds following it. No wonder she’s been confidently flaunting her flawless looks on Instagram! Jameson also uses the platform to update fans about her ventures, including collaborating with Mom Cave Foods’ spice company in 2020.
