After decades of wondering, Jennifer Aniston has finally revealed the secret behind her famous figure.
The Friends star, who is 50 but arguably has the body of a woman half her age, has admitted she’s’s a fan of intermittent fasting, using the 16:8 fasting diet on a daily basis, only eating during an eight hour window of the day, while eating nothing for the remaining 16 hours.
“I do intermittent fasting, so no food in the morning,” she told Radio Times magazine.
“I noticed a big difference in going without solid food for 16 hours.”

While it might sound pretty hectic to not eat for more than half the day, Jen explained sleeping counted as part of it.
“Fortunately, your sleeping hours are counted as part of the fasting period. You just have to delay breakfast until 10am,” she said, explaining she kicks off with a celery juice each morning but “stops (eating) by 5 or 6pm, when the fasting begins anew”.
She also explained she’s not completely rigid with her diet, allowing herself a “cheat” day once a week.
In the past, Jen has talked about how she has always prioritised her health, staying in shape with daily boxing, cardio sweat seasons as well as yoga and meditation.
“I feel really beautiful when I finish a great workout,” she told People magazine after winning 2016’s World’s Most Beautiful Woman.
“Because I’ve taken care of my body, my endorphins are going, my blood is pumping. I’m taking care of the one body I have.
“I have a spin bike, an elliptical bike and a treadmill — and I do cardio for at least 20 minutes a day. Even that short burst makes a difference.”
She did also talk about how important it is to “rest the body” saying sometimes she goes a whole week without hitting the gym.
“It’s hard work, you know. You work out, you just take care of yourself and you exercise,” she said, adding that eating right and getting enough sleep is her secret to happiness.
The Hollywood superstar, who recently joined Instagram and already boasts a staggering 15.5 million followers with just four posts, is super relatable with her body views too, admitting she used to moan about the way her booty wobbled to her mum.
Studies say an intermittent fasting diet will help people lose and control their without causing you to starve yourself.
It’s also known as time-restricted eating — or TRE — something Adelaide researchers earlier this year found has a range of health benefits, including losing weight faster than people who ate fewer calories and had improvements in blood pressure.
It is also said to help reduce the risk of cancer and heart disease, lower cortisol levels (ie. eliminate stress) and reduce inflammation.
Another popular form of intermittent fasting is the 5:2 diet which is hailed by many as the easiest way to lose weight and keep it off.
“It’s just five days of the week where you eat normally — but when I say normally that doesn’t mean pizza and coke,” the author of The Anti Ageing Food & Fitness Plan told news.com.au.
“Then the other two days, which don’t have to be in a row, you are restricted to five, six, seven hundred calories, depending on whose regimen you’re following.”
Despite being praised by many health experts as a way to lose weight healthily, some dietitians warn it’s just another “fad” and to tread carefully.
“The main reason that people try fasting is to lose weight — but I’m sorry to disappoint, research has shown that fasting is no more beneficial for weight loss than a standard calorie-controlled approach,” dietitian, Melissa Meier, told Body & Soul earlier this year. “That’s not to say it won’t help you lose weight, but rest assured it’s not a magic bullet.”
