Book excerpt: Jim Karas's health and fitness book shot to number one in its first appearance on the New York Times's 'Advice and How-to' bestseller list. To capture an increasingly cynical fitness market, Jim needed a unique approach. And he found it. He turned his business training into practical, easy-to-follow steps to lose weight. He used simple tried-and-tested business analogies to draw parallels with weight-loss, with fantastic results. As a result, anyone familiar with the principles of business can lose the pounds his way, using simple ideas like mission statements and monthly targets: weight-loss is profit after all. This book maps out the exact route to follow, not just to lose weight and become fit, but to remain that way. Blowing the lid off the old excuses, Jim motivates the reader through the programme and gives them the desire to succeed.
