The star’s wellbeing secrets include fasting, meditation and five workouts a week. But when does she have fun?

Name: Jennifer Aniston.

Age: 50.

Appearance: Almost the same.

Almost the same as what? Almost the same as how she looked 20 years ago, when she was starring in the hit series Friends, according to MailOnline.

Amazing. What is the secret of her youthful appearance? Not eating.

That doesn’t sound ideal at all. Well, more specifically, she’s adopted an “intermittent fasting” regime, more commonly known as the 16:8 diet.

Is it like the 5:2 diet, except you starve for 16 days and then binge for 8 days? No, in this case the numbers represent hours. “I noticed a big difference in going without solid food for 16 hours,” Aniston told the Radio Times.

Sixteen hours without food? By the time you’re allowed to eat, it would be past your bedtime! Fortunately, your sleeping hours are counted as part of the fasting period. You just have to delay breakfast until 10am.

I could probably just stay in bed until then, as long as I were allowed to eat what I liked afterwards. You eat anything, but you must stop by 5 or 6pm, when the fasting begins anew.

And does it actually keep you young? Who knows. Some people believe it is supposed to keep you slim, improve blood sugar control, boost brain function and increase life expectancy.

You know what’s guaranteed to make you feel old? Eating dinner at 5pm. Most intermittent fasters prefer the more convenient 12 to 8 eating window, but 10 to 6 is considered optimal.

Optimally joyless, do you mean? Obviously Aniston isn’t completely rigid about the whole thing. She has a “cheat” day once a week where she treats herself outside fasting hours.

And what does she have? Celery juice.

She treats herself to a celery juice? What an example to us all. Indeed she is.

I was being sarcastic. She is certainly an example to Reese Witherspoon, her co-star in the new series The Morning Show. “Jen knows so much about health and fitness that I always defer to her,” she told the Radio Times. “She’s great at wellbeing advice.”

Is there more to her wellbeing regime? In addition to fasting, Jen does meditation, followed by five workouts per week. Witherspoon, the swot, manages six.

I don’t understand how these people find time in their schedule to get drunk. They don’t need to get drunk; they get high on being a better person than you.

Do say: “Fasting, meditation, exercise: what a great way to use up the hours between now and death.”

Don’t say: “Focus, Jen. It’s nearly 6pm, and this box of doughnuts isn’t going to eat itself.”
