But the eating pattern isn't necessarily right for everyone.


If you've ever found yourself wondering what Jennifer Aniston's secret is to ageless skin/hair/body/etc., you're definitely not alone. And TBH, she hasn't been one to dish out too many tips over the years—until now, that is.

While promoting her new Apple TV+ series The Morning Show, Aniston revealed that she takes care of her body by practicing intermittent fasting (IF). "I do intermittent fasting, so [that means] no food in the morning," the 50-year-old actress told U.K. outlet Radio Times, according to Metro. "I noticed a big difference in going without solid food for 16 hours."

To recap: IF is characterized by cycling between periods of eating and fasting. There are several approaches, including the 5:2 plan, where you eat "normally" for five days and then consume roughly 25 percent of your daily caloric needs (aka about 500 to 600 calories, though the numbers differ from person to person) the other two days. Then there's Aniston's more popular approach, which involves daily 16-hour fasts in which you eat all your food in an eight-hour window. (See: Why This RD Is a Fan of Intermittent Fasting)

Not eating for 16 hours at a time might sound challenging. But Aniston, a self-proclaimed night owl, revealed that intermittent fasting works best for her since she spends most of that time sleeping. "Fortunately, your sleeping hours are counted as part of the fasting period," she told Radio Times. "[I] just have to delay breakfast until 10 a.m." Since Aniston usually doesn't wake up until 8:30 or 9 a.m., the fasting period is a bit less daunting for her, she explained.

Intermittent fasting has become an increasingly popular trend over the past few years. Studies have shown that it can help with weight loss, as well as improve metabolism, memory, and even mood. Research also supports IF's positive effects on insulin resistance, not to mention its potential to decrease inflammation and support a healthy gastrointestinal tract.

While that all sounds great, intermittent fasting isn't for everyone. For starters, it can be quite difficult to sustain. Unlike Aniston, many people struggle to comfortably fit fasting and eating periods into their work and social life, Jessica Cording, M.S., R.D., C.D.N., previously told us. Then there's the issue of making sure you're fueling and refueling your body appropriately around workouts, especially since IF only tells you when to eat, not what to eat to stay healthy and balanced.

"I've seen many people who hop on and off the IF bandwagon start to feel out of touch with their hunger and fullness cues," explained Cording. "This mind-body disconnect can make it difficult to establish an overall healthy diet for the long haul. For certain people, this could lead to or resurface disordered eating behaviors."

If you're still thinking of trying intermittent fasting, be sure to do your research and consult your doctor and/or a certified nutritionist before making any major changes to your diet.
