Here's a CNN report about a Kansas State professor who lost 27 pounds on Twinkie and Swiss Role based diet, which is funny because that almost mirrors my experience in Egypt (where Twinkies cost 5 cents and are on every corner). The conclusion the article draws is that to lose weight, calorie input vs output is pretty much the only factor, which is true as far as I can tell. My conclusion is different: Losing weight does not make you healthy. It might make you healthier, if obesity related health problems are serious for you. They're not for me. Like the article says (or should say) healthy varies from person to person. I just like this article because it confirms my belief (which is always nice) that the common description of healthy foods as low-fat and low-calorie is not a universal description of healthy and that overall, skinny does not equal healthy.
