As someone who struggles with excessive weight, "Fat, Sick and Nearly Dead" was a highly motivational movie for me.  Seriously, it tells the tale of super healthy massive weight loss (more than 1lb per day), and all you have to do is drink juice.  Well, actually, that's ALL you do.  The movie tries to get people to commit to a ten day "juicing", where all their intake is either fresh juice (from raw veggies in a food processor) or water.  I admit, after watching the results, I was tempted to give it a go.

On the surface, you might think "Hey, they turned an infomercial into a documentary" since the message is too good to be true.  Just do this and all your problems go away.  Not just weight loss, but you feel better, have more energy, and can even drop medications.  It almost certainly is an ad for Breville food processors, what with all the product placements.  But never once do they say "Buy this brand".   The only purchasing advice they give is to buy local organic fruits and veg.

The movie itself is frustratingly short on details.  The only thing they say is that you can only drink fresh juice.  They don't say which fruits and veggies, how often, how much, or even if you can prepare a pitcher of juice for the day and just keep whittling away at that.  Instead, at the end, they have a link to their web site, which is just a front for another site called jointhereboot.com http://www.jointhereboot.com.  On that site they have a few plans depending on how extreme you want to get, but my first thought was "Oh, here's where they get you to buy something."  Nope.  All their meal plans are free, and you can find them listed on the site.  Unfortunately, the plans all included solid meals to supplement the juicing.  Huh?  Where's what the people in the movie did?

Since straight juicing, like the folks in the film did, was all the appealed, I went hunting on the net for more info.  If I was going to eat, then I knew I'd eat food I wanted to eat.  Sticking to just juice seemed somehow easier, in my mind.

I found tons of anecdotal "I love the juicing!" and "I hate the juicing!" and "Juicing is bad!" and "Juicing is awesome!".  In the end though, whether or not the people would ever juice-fast again, they all came away with the same change.  They would include more vegetables in their regular diet.  Maybe that's the real lesson here.  Just be healthy.

Supporting that conclusion is a quote from Web MD http://www.webmd.com/diet/features/detox-diets-cleansing-body-feature:

Quoted Text

"There's nothing wrong with going on a juice fast for a few days," [James Dillard, MD] says. "But it's not a great way to lose weight, because you'll gain it all back -- you yo-yo. It's just like the Atkins diet. The weight you lose is water weight."

Eating less -- that's definitely known to extend life, Dillard says. "The only reliable way to extend the lifespan of a mammal is under-nutrition without malnutrition."

"The old-fashioned way of eating the right foods, getting exercise, clean living, keeping a positive mental attitude -- that's what works," he says.

While the film was great and motivational, and I recommend watching it, I personally fear the juice-fast diet.  It does seem too extreme, and there are concerns over malnutrition (since you're missing necessary vitamins and minerals), and downright miserable for many people.  Frankly, I'm just going to renew my efforts to stay healthy.

The Good: Great weight loss success stories without mocking fat people
The Bad: A bit preachy.  The host is seen extolling the nutrients of his juice to someone eating liver.  Liver is far more nutrient dense than a juice.

Juice: Apple http://nutritiondata.self.com/facts/fruits-and-fruit-juices/1809/2 + Spinach http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/2626/2
The Ugly: The lack of diet details.  It's very hand wavy and leads one to think they DON'T want you to do exactly what they did.  Reminds me of the caveat to every diet/herbal/exercise ad: * Results not typical.
