First off, intermittent fasting is almost exactly what it sounds like. It generally consists of going without food for a period of time, then eating normally. The most popular type — 16:8 — consists of getting all of your calories for the day in an eight-hour window (say, from 10 a.m. to 6 p.m.), then fasting for 16 hours overnight. Another method is the 5:2, in which you eat normally for five days a week, then restrict your calories severely (typically 500 for women) for the other two.
As for weight loss, the stars know what they’re doing! “In a nutshell, intermittent fasting works,” NYC-based dietitian Keri Glassman tells Us Weekly. “Here’s why: For most people, you’re restricting calories and largely cutting out food you shouldn’t be eating anyway.” However, warns the nutrition pro, “That doesn’t mean that I would necessarily recommend it for everyone.”
The fasting method “requires regimented commitment,” she notes, adding that for some, it can lead to unhealthy eating and “set the person up for yo-yo dieting.” The best candidates, Glassman explains, are already-healthy eaters who don’t mind skipping breakfast and can make solid food decisions even when they’re hungry.
Above all, she says, besides having the willpower to fast, “you need to eat a healthy, balanced, real-food diet during the other hours.”
“Instead of restricting what you eat, it focuses on when you eat your meals,” the article read. “IF has been shown to help with weight loss, aid cholesterol regulation, improve overall health, encourage self-control and heighten concentration.”
The Keeping Up With the Kardashians star also tries to have an early dinner and stops eating around 7 p.m. In order to “squash a sweet craving,” the mother of three likes to sip on hot green tea or water with a splash of apple cider vinegar.
Aniston, on the other hand, lives by the 16:8 fasting timeframe, so that “there’s no food in the morning.” The Morning Show actress told Radio Times in October 2019 that she sticks to liquids like celery juice or coffee in the morning so she can maintain a no solid food plan for 16 hours a day.
