"Friends" actress Jennifer Aniston seems to be divulging all her secrets to success.
Now, the 50-year-old is giving insight into the daily wellness routine that helps her thrive.
"I wake up at 8:30 a.m or 9 a.m., but go to bed late. I'm a night owl," Aniston says.
Immediately after waking up, Aniston says she drinks a glass of celery juice. The habit is popular among celebrities, who drink the juice on an empty stomach. Some say it reduces inflammation and improves gut health but other nutritionists say there is no evidence or science to back up those claims.
Aniston also brews some coffee — but doesn't drink it right away.
"I don't drink coffee that early," Aniston tells the site. Instead, she typically feeds her dogs, mediates and does a morning workout, then has her coffee.
Aniston is also one of the celebrities and entrepreneurs doing intermittent fasting — it entails eating normally for eight hours a day, from 9 a.m to 5 p.m., for example, and then consuming nothing but water, coffee or tea for the other 16 hours.
"I do intermittent fasting, so there's no food in the morning. I noticed a big difference in going without solid food for 16 hours," Aniston tells Radiotimes.com.
Intermittent fasting has been an increasingly popular trend over the past few years. There is some research showing it can improve memory or mood, but researchers have noted that the potential long-term risks are still unclear. (Experts also advise against some people, including the elderly, pregnant women and children, doing any type of fasting. And they caution there are risks with extreme fasts and fasting that lasts longer than 24 hours.)
While Aniston says she fasts every day, she does allow herself a food "cheat day" on Sundays, though she didn't elaborate on what she eats.
On Oct. 15, Aniston "broke" Instagram when the actress joined the social media platform after boycotting it for years. According to the Guinness World Records, Aniston now has the record for the fastest time in reaching 1 million followers, at five hours and 16 minutes. (The title was previously held by Prince Harry and Meghan Markle, who reached 1 million in five hours and 45 minutes.)
