I was disappointed to read this week's Time magazine cynical headlining

article: Why Exercise Won't Make You Thin (www.time.com/time/health/article/0,8599,1914857,00.html) in which they discount the value of exercise for weight loss. Sounds crazy to all of us who have benefited from regular workouts to drop pounds! If you read this piece (which seems like it took the angle it did to get publicity), the problem is not exercise, it's the writer's ATTITUDE toward exercise. No,

exercise should not be "hateful" and "grim" but enjoyable. Of course, it has always been true--and something we have always said in Shape--that you MUST also watch what you eat. You can't sweat and then, as the writer admits, go off and eat French fries or a giant donut and expect to lose weight. Getting your eating under control as well as keeping your body moving is key to dropping the pounds: this is something that Shape has always advocated and always will (because it's the only thing that works). And note to all: this does not mean always avoiding treats, it means eating them in moderation.

One daily change: Keep exercising! As we say in an upcoming article for Shape, research shows just moving your body for 30 to 60 minutes a day boosts your immune system (meaning fewer sick days), helps you sleep more soundly, helps stave off memory loss, makes you happier (and kicks your self-esteem up a notch), helps you cope with stress, and helps you perform better in just about everything you do (sex, your career, your relationships, etc). AND yes, it also helps you sculpt muscles, increase bone density, AND keep you slim.
