First Jennifer Aniston and her good friend Reese Witherspoon revealed they're fans of intermittent fasting and now model Rosie Huntington-Whiteley says she also follows the diet plan. Speaking in the Sunday Time Style Magazine, Rosie said she consumes her food in an eight to ten-hour window. "I'll have a matcha tea with oat milk at 8am - that's the most LA thing about me," she said. "Then I try to finish eating between 4pm and 6pm. It gives my body a chance to digest everything." Hollywood actresses Jennifer and Reese also recently spoke of the meal plan, opening up about their lifestyles to the Radio Times.

Jennifer said: "I do intermittent fasting, so no food in the morning. I noticed a big difference in going without solid food for 16 hours." Reese added: "Jen knows so much about health and fitness that I always defer to her. She's great at wellbeing advice." Jennifer reportedly drinks a daily celery juice, while Reese likes to have a green juice. The pair give themselves one cheat day a week.

We can barely imagine fasting for 16 hours a day, but it seems Jennifer's sleeping hours help matters. She is said to wake at 9am, drink her celery juice, mediate and then workout – at least five fitness sessions a week – and Reese gets up at 5.30am, training at the gym around six days a week.

What is intermittent fasting?

The 16:8 diet is growing in popularity, involving restricting food consumption to a set time of eight hours a day and refraining from eating for the other 16 hours. For example, you could eat between 10am and 6pm or between 9am and 5pm. It's advised to eat regular small meals full of whole foods and healthy drinks.

Does intermittent fasting work?

Fans of the eating plan credit it with helping to shift weight, increase longevity and controlling blood sugar levels. However, as with many diets, there can be downsides. Binge eating within the eight-hour window negates the positive effects and can cause initial side-effects like increased appetite and tiredness.
