In her book Lessons, Bündchen revealed she follows the popular 5:2 version of intermittent fasting, which involves eating normally on five days of the week and restricting calories to 500-600 calories on the remaining two.
While the fasting window is up to the individual, the Brazilian supermodel explained she fasts until lunchtime two days of the week to allow her body time to rest and digest.
Aniston disclosed her penchant for intermittent fasting in October 2019, saying since starting, she's "noticed a difference" in how she looks and feels.
In an interview with Radio Times, she said: "I do intermittent fasting, so there's no food in the morning." Instead of having a large breakfast in the A.M., Aniston told the magazine: "Today, I woke up and had a celery juice. Then I started to brew some coffee, but I don't drink coffee that early."
In 2018, Kourtney Kardashian explained that she's a fan of intermittent fasting in a post made on her official app.
Kardashian, who founded the health and lifestyle website Poosh in 2019, wrote of her diet: "I wouldn't eat past 7 p.m. at night and then I would wait to eat breakfast the next day until after my morning workout, which would be around 10:30 a.m. to 11 a.m."
In November 2018, Halle Berry revealed her love for intermittent fasting via an Instagram story post.
Speaking with her personal trainer, Peter Lee Thomas, Berry revealed that she fasts most mornings and eats her first meal of the day around 2 p.m., saying: "Not that I don't get nutrients and vitamins and minerals [during that time]... I just don't sit down and have a meal."
Witherspoon hasn't explicitly used the words "intermittent fasting" to discuss her diet, but told Radio Times in 2019 that, like her Morning Show co-star Jennifer Aniston, she only consumes fluids (i.e. coffee and "green juice") in the mornings.
In May 2019, actress Vanessa Hudgens revealed that she's a fan of the popular 16/8 variant of the intermittent fasting diet—meaning that she eats between eight hours of the day, and fasts for the remaining 16 hours.
In an interview with POPSUGAR, Hudgens said she's already seeing benefits from the diet, saying that when she started, she had "way more clarity, and I was more energised and felt even stronger in my workouts". Despite feeling better, Hudgens warned of the diet: "It's rough, it's no joke. I'm not gonna lie and say it's easy."
The Office's Mindy Kaling has apparently tried an intermittent fasting diet, if a humorous tweet she made in 2018 is anything to go by. Referring to the popular '16/8' variant of intermittent fasting, Kaling tweeted: "16:8 more like 16 hate."
