Zone Diet celebrities love to follow the Zone diet for obvious reasons. They include Charlie Sheen, Madonna, Ben Stiller, Bill Cosby, Sarah Jessica Parker, Demi Moore, Lorraine Bracco, Brian Leetch, Mekhi Phifer, Min and Yoon Kwon, Monica Crowley, Gordon Chambers, Renee Zellweger, Cindy Crawford, Jennifer Aniston, Sandra Bullock, and Kevin Costner.
These people have even more motivation than we do. Their careers depend on their ability to keep on looking good and fit no matter how many years goes by.
They value their health of course, because nobody wants to be sick. And they don't want to look or feel older.
Yet for most of us, that's all our personal business. If we gain ten pounds we don't get fired. Or if wrinkles overpower our faces our incomes don't go down.
That's not true of such Hollywood celebrities as Charlie Sheen, Renee Zellweger, Cindy Crawford, Madonna, Demi Moore, Sarah Jessica Parker, Ben Stiller, Bill Cosby, Jennifer Aniston, Sandra Bullock, and Kevin Costner.
True, they make a lot of money per movie. But what happens when they're no longer in the movies?
And these celebrities are faced with even more temptation than the rest of us. Hollywood producers put on lavish spreads of food just for the extras of the casts of their movies (my mother was a small time actress who occasionally did work in movies, and so she saw this herself firsthand.) So they are certainly willing to get any food possible to keep their stars happy.
And that's while they're working. A lot of their work consists of going to parties to publicize their movies. And when they're not on tour to promote a movie, they're going to private parties with their friends or or going out to clubs.
So what does everybody do at such times? What everybody has done since time immemorial -- eat and drink.

These Hollywood and other celebrities of course have access to the best medical advice and care. If there was an easy fix to keep them healthy, thin and young, they could afford it if anybody in the world could.
So we can believe they probably do take lots of vitamin pills and food supplements, but that's just not enough.
You need to keep your insulin in balance with your glucagon. Too much, and your system is out of the Zone, and that's damaging whether you're an ordinary person or a famous star.
Of course, nobody follows the Zone diet perfectly. Right now, Charlie Sheen may not be the preferred poster child for any kind of healthy diet or system.
But that's just evidence of whatever personal issues Charlie Sheen has, plus the great temptation he faces, and the greater ability to eat and drink to excess.
It's very possible that such celebrities who follow the Zone diet also enjoy eating Balance protein bars, because that is a convenient way to keep them in the Zone, and they're delicious. And of course the cost of these meal replacement bars is insignificant to the rich and famous.
So stars such as Charlie Sheen, Renee Zellweger, Cindy Crawford, Jennifer Aniston, Madonna, Ben Stiller, Bill Cosby, Demi Moore, Sarah Jessica Parker, Sandra Bullock, and Kevin Costner can encourage us to follow the Zone diet to keep ourselves as young, thin and healthy as they are.
