7lbs In 7 Days Book Review
Jason Vale - the self-proclaimed Juice Master - claims that by living on his life-affirming juices and nothing else for a week that you will lose at least 7lbs.
It’s quite a claim so I decided to buy a copy of his book and take a closer look.

The first thing to say is that Vale seems to enjoy swearing in his book - he seems to do it just to try and get attention and while I’m not immune to a little swearing myself it did get a bit tiresome after a while.
Perhaps the reason he likes to swear is that he comes across as such a self-confident (almost cocky) individual and I, for one, found it very difficult to like the character writing the book. This is in sharp contrast to, for example, Bill Philips in Body For Life. I just kept thinking “stop blowing your own trumpet!”.
Most medical practitioners these days recommend around 1-2lbs of weight lost per week when dieting and it’s interesting (and revealing) to here Vale explaining how his diet fits into this.
Basically he says he doesn’t care. His readers want to lose weight fast so who cares if it goes against medical recommendations?
In terms of fairness I should say that I have publicly lost well over 2lbs some weeks here on this blog so I am in no way saying I am perfect but I do point out what is recommended and his relaxed attitude I find a little hard to swallow.
Then there’s what I see as somewhat hokey science. Vale agrees that digesting food takes up a lot of energy for the body which is why so many diets, such the the Body For Life diet recommend eating 6 small meals rather than 3 larger ones, but Vale then claims that by juicing the ingredients, and so saving your body expending extra energy that it is “saved for the task of removing fat”.
Seems a very strange claim and is only one example of many that made me think “Now hang on here, where is the science to back up those claims”.
With this avalanche of negativity toward the 7lbs In 7 Days book you’re probably assuming you shouldn’t buy it.
But I don’t think it’s as easy as that. You see, the evidence suggests that the actual diet itself does work - it’s an interesting, successful weight loss regime - even if you take into account Vales various ways of “cheating the system”.
For example he recommends weighing yourself the night before you start the diet then the morning after you finish the diet to check you’ve lost 7lbs or ore. Well, pardon me, but by weighing yourself then (a) you’ve got an extra half a day of time to lose weight and (b) we all weigh less first thing in the morning than last thing at night so you’re going to show weight loss doing this even if you don’t follow the diet.
He also recommends 2-3 exercise sessions of 20-30 minutes each, per day. That’s up to an hour and a half of cardio per day which, again, would help anyone lose weight irrespective of their diet.
No matter. However you cut it, this diet does seem to work.
It’s just wrapped up in what, to me, was a dreadfully written, boring and repetetive book.
You’ll have to wade through a lot of rubbish within the covers but if you follow the core principles it’s likely you’ll lose quite a bit of weight without too much difficulty - and isn’t that what we all want?
