Many celebrities can afford to lather their faces with expensive treatments and undergo surgeries to look years younger than they really are.
Jennifer Aniston and Reese Witherspoon are praised for their youthful looks and they don't rely on these processes, instead, the believe fasting, an incredibly disciplined task, is to thank for their flawless skin.
Aniston, 50, and Witherspoon, 43, stick to a strict 16-hour fasting period daily, drink green juices and do intense workouts six days a week.
The pair admit that they give themselves one cheat day a week to have whatever they desire - which in Aniston's case turns out to be celery juice, the star told Radio Times.
