Sugar is not sugar and your body does know how to tell the difference, thus processes them differently. Natural sugars (those found in veggies and fruit) are burned at a much slower rate than refined sugars such as those found in high fructose corn syrup and enriched (stripped of the good) starches such as white flour and white rice. These sugars are metabolized at a much higher rate thus turning to fat unless you are on a 24 hour cardio sesssion. However, moderation is the key to natural sugars. Any intake greater than your base metabolic rate can handle plus your exercise routine will result in a higher body fat composition. There are good carbs and bad carbs.
