I haven't seen that Planter's ad, but I see no problem with producers of REAL food claiming their low carb status. It's when it's deliberately misleading that it makes me mad. It all comes down to this: "The whole point of the carb-related food claims, says Liebman, is to make you think you can lose weight simply by eating these foods."

The cynic in me says that people who are that easily duped deserve to NOT lose the weight. The only way to do it - be it low fat, low carb, whatever - is to (a) learn as much as you can about your chosen WOE, and (b) eat real food most of the time. But, of course, I'm preaching to the choir here...
