Jenna Jameson, 47 – Internet Business Owner

Jenna Jameson shot to fame in the adult entertainment business. Her career started in glamour modeling before appearing in a series of ’90s videos.

After welcoming the daughter she shares with Lior Bitton in 2017, Jameson lost 80 pounds in six months. The keto diet combined with intermittent fasting was the secret behind her success, and she was also candid about her struggles with loose skin. In 2020, she started back on keto after regaining 30 pounds.
