Good-looking celebrities such as Sofia Vergara, Gwyneth Paltrow, and Salma Hayek have all admitted to being on a juice cleanse at some point in their lives.

A juice cleanse is when you give up food and drink only fruit and vegetable juices for anywhere from a day to a few weeks. Or, in Ali’s case, four hours.

So why would anyone do that? Ali asked AJ Jacobs, author of ‘Drop Dead Healthy: One Man's Humble Quest for Bodily Perfection,’ who tried a cleanse or two for his book. Do people really need to clean their organs? Or are they just trying to lose weight quick?

According to Jacobs, a juice cleanse doesn’t really help you do either. Any weight you lose during a cleanse will come back once you’re done. “An easier way would just be to restrict your calories and eat normal food.”

And cleaning toxins out of your body? Well, that’s what your kidneys, liver, and intestines do anyway.

Both Ali and AJ admitted to getting light-headed and spacey when attempting a cleans

Why do men do the things they do?  Why are they obsessed with video games and fantasy sports?  Why do they love terrible bands?  Why do they read on the toilet?  Ali gets to the bottom of some of the most mysterious male behavior with Roger Hailes of the Yahoo! Show, Mansome.
 
Roger was more than happy to be the unelected spokesman for men everywhere. A main motivator for men, he says, is to be able “to participate in something without actually doing it.” Roger estimates that, after a few months of playing something called ‘Assassin’s Creed,’ (which is something called a ‘video game’) he’d be a really excellent “high level assassin.”
 
As for why they read on the toilet, Roger says the more important question is, “Why DON’T women read on the toilet.”
 
Ali also wondered why men grunt at the gym.  The answer to that one is apparently simple:  because people grunt when we try.  Roger tried to convince Ali that women do it too, but his only concrete example was Wimbledon.

It's one of the biggest health dangers since smoking…and you're probably doing it RIGHT NOW.  Are you sitting down?  Because that’s it!  (No really, that’s the health danger.  Sitting.) If you sit for more than four hours a day, your heart disease risk goes up 60 percent, according to a study from University College London.
 
Ali, who enjoys sitting as much as the next person, didn’t want to believe the hype.  So she asked AJ Jacobs, author of Drop Dead Healthy: One Man’s Humble Quest for Bodily Perfection, if there were any truth in the warnings.
 
Sadly, according to him, “If you sit all day, it’s bad for your weight, metabolism, and blood sugar level.”
 
But with so many other health threats out there, a person’s got to prioritize.  So Ali asked AJ to rank the hazards of smoking, motorcycles, artificial sweeteners, alcohol abuse, and sitting in order from least to most dangerous.  Watch Daily Shot to see what he said!
