I found this to be quite informative from the Atkins site--some of us are trying to do more high intensity workouts which last for more than an hour, so it may be reasonable to add more good carbs.

These articles are more on pre-nutrition than post-nutrition, but I think that there is some truth to fueling back up with a balanced meal. I suspect that as we continue to get athletic that maintenance levels of carbs are more appropriate even if we are still trying to lose weight at the same time. It's certainly proportional to activity level.

Because of the hormonal response associated with carbohydrate consumption,
some research has even suggested that there may be a deleterious effect from consuming carbohydrates immediately prior to exercise.1 Specifically, these authors have suggested that increased insulin in response to this
carbohydrate load can result in decreased available blood glucose for
energy. Although this topic is controversial, the most popular recommendations from the American College of Sports Medicine and the
American Dietetic Association suggest that pre-competition carbohydrate
ingestion should occur at least three to four hours before activity begins.2

Because fat burning does require some carbohydrate metabolism, it is
recommended that in events lasting an hour or more, 30 to 60 grams of
carbohydrate should be ingested to enhance performance (amount depending
upon intensity and duration of exercise). 7
