Really there is no "recommended" number as far as I know. I have "met" people online who can eat only 10-15 net carbs and lose weight, and others who have got up to eating 100+ net carbs and are worrying about how the heck they can stop losing weight.
All you can do is try one number and see what happens.

If after any "woosh" of weightloss in the first week or so (most lose a lot of "water weight" to start with) you still lose weight quickly you might see what upping your carbs does, if you lose nothing then try lowering the carbs (or drop the chocs/wine for a week or so)
