Are Juice Fasts Actually Healthy?


When I was in college, I decided that doing a juice fast was the perfect way to get my health back in order. Six hours and two glasses of juice later, I gave up; I was hungry, weak, and supremely grumpy. If this was how I felt after just a few hours, how on earth could I last an entire week?

I may lack the willpower to go on a juice fast, a regimen where you subsist only on fruit and vegetable juices for as many as several weeks, but plenty of other health-conscious people swear by them. And yet, despite claims that juice fasts detox the body, help you lose weight, and even cure serious illnesses, most mainstream medical professionals are speaking out against the practice.

So who should you believe? Let’s take a closer look at the claims, and the science, behind juice fasts.

I hate this article. Just encouring people to make healthy choices.

"I was hungry, weak, and supremely grumpy. If this was how I felt after just a few hours, how on earth could I last an entire week?"

Maybe that was your body adjusting to the new regimen, and if you had stuck it out, you would have started to feel better. I completely disagree with your claim that 800 calories from cookies would be the same as 800 calories from fruits and veggies. Think about it, and you'll figure out why such a statement is absurd. I do agree that juices lack fiber. That's because the juicer extracts the fiber and skin, which can be very important parts of the fruit or vegetable. I suggest using a blender, instead, at least for some fruits. (Some tough veggies, like carrots, can be hard to puree in a blender.)

BTW, there is a story going around (it might be here on Care2) about a man who weighed over 400 lbs. and went on a juice fast. He not only lost weight, he cured his health problems, took pressure off his spine, legs, and hips, and felt better both mentally and physically. His motivation was that he wanted to live longer to watch his son grow up. He now goes around the country giving lessons on juice fasting, and many communities take part in group fasting to get healthy. If anyone knows the guy's name and has a link, could you post it here?

Perhaps the only misnomer the author needs to heed is that it should not be Juice "Fast" but rather Juice "FEAST" instead.

This isn't about drinking a limited amount of 2 glasses of juice. This is about drinking as much as a gallon each day. This is about washing your cells with concentrated nutrients and it's about adding in greens in abundance too.

I happen to personally know people who have done "feasts" of many days including 90, 100, 200 days and more who also bike to work (and back).

Nothing in this article seems to come from anything but hearsay the author wants to believe anyway to support having given up in less than a day.

Watch, "Fat, Sick & Nearly Dead" which is playing for free on YouTube at the moment. Might change your ideas.

And a supposed lack of "protein" in a world where we get way too much and suffer Diseases of Affluence because of it, will not kill us. All religions have fasts as part of their ideology because it gives our digestive system a break. Digestion is energy intensive!

Also, what is "mainstream"? Seems that is the SAD (Standard American Diet) which includes Disease Care (not "Health" Care), a bunch of Pharma which is essentially a form of addiction (especially for Wall Street), and lobbyists to make us believe the Snake Oil claims.

I concur with the few sensible-minded people who commented on this article.

The author obviously doesn't understand how juice fasts work or why people do them in the first place.

It's a big mistake to assume that it is a diet or a fad.

When will people on here learn to research the facts behind an article instead of automatically believing someone's opinion as gospel truth?

I guess you have to justify the expensive of a juicer somehow (that is, if you have one).

Quite useful information... Will have me thinking twice about a juice fast..

From time to time I drink freshly-squeezed vegetable juice (often mix)- carrot, cabbage,beetroot adding parsley/ celery or simply a tomato smoothie. Rarely freshly-squeezed apple juice for I prefer eating whole fruits.

Thank you for the education.

This seems a tad biased to me - besides, instead of juice you can always go with the whole fruit and make it a smoothie.
