Book Nook: Baby, you can drive your carbs

CHOOSE TO LOSE: The 7-Day Carb Cycle Solution, by Chris Powell. Hyperion, 202 pp., $24.99.

Fans of ABC's "Extreme Makeover: Weight Loss Edition" will recognize fitness trainer Powell's fit physique and blazing smile on the cover. A "transformation specialist" who helped David Smith of TLC's "The 650-Pound Virgin" lose more than 400 pounds, Powell writes why he likes working with the "super obese": "They are living proof of the body and mind's amazing ability to transform. And if they can do it, anyone can do it: especially you."

His carb cycling plan alternates high-carb with low-carb days -- and "shapers" or "shredders" exercises so your body won't adjust and ratchet down its metabolism.

THE SCOOP If you hit a plateau, you might try the "slingshot" technique -- seven high-carb days in a row.

THE BOTTOM LINE Powell's SMART plan is Specific, Measurable, Attainable, Realistic and Time-Sensitive. Those principles, a gallon of water and five small meals a day, he says, will help you succeed.
