Just when you think you’ve heard everything there is to know about childhood obesity, out comes new and refreshing information that will prompt you to re-think the most commonly recommended practices for kids who struggle with overweight.  Our two guests this week, Fred Hahn and Francie Berg, are both internationally recognized experts in fitness and nutrition.  Consider this quote from Fred, which is excerpted from his latest book, Strong Kids, Healthy Kids:  “Truth be told, almost all the so-called fitness programs for getting kids lean and strong are either wrong or misguided.  Almost all of the books on the subject of how kids eat are wrong.  As we all know, kids today are more unfit now than ever before in history.”  Fred explains the most helpful, hopeful things parents can do for their kids, and it’s all based on leading scientific research.  In addition to being a parent, Fred also serves as the president and co-founder of the National Council for Exercise Standards, he’s a celebrity fitness trainer, and the author of The Slow Burn Fitness Revolution, a bestselling weight loss and exercise book.  Our second guest, Francie Berg, is the founder of the Healthy Weight Network and the author of 12 books on healthy eating and nutrition.  She’ll be discussing her latest book, Underage and Overweight:  Our Childhood Obesity Crisis.  What every family needs to know.  Francie claims the childhood obesity crisis is largely exaggerated and often leads to extreme, harmful behaviors in parents and kids.  Francie gives 10 powerful reasons why kids should not diet, and she tells how to access several free, helpful reports from her website.  Host Karen Bentley shares the latest and greatest news from the December 2008 UC Berkley Wellness Letter about how to rev up your metabolism, which is the rate at which your body burns calories.
