I tend to stay out of the debate to an extent because I'm no dietary expert, and because there's always so much disagreement in regards to what an ideal diet truly should be versus a weight-loss diet, but my layman understanding of the situation is that while some types of carbs are fine and in fact healthy, overall, cutting carbs tends to be one of the more effective methods of weight loss. Further, I think it's generally understood that the typical nutritional info on packaging overestimates how many carbs one needs.
Mind you, I'll defer to people who know more than me. However, it's always difficult to get to the crux of the issue, as many people of apparent knowledge on the topic will often advocate different ideals.
