I've considered it too, but had the same concerns. Mr. X posted his experience with it in the thread I started a while back.. He had exact carb numbers along with times and his corresponding ketone/glucose readings. the amounts you need to eat are going to vary based on the number of sets you do. You have to reach a balance between having enough glycogen to fuel your muscles, but little enough that glucose stays low enough for you to quickly reestablish ketosis. Lyle McDonald actually gave a formula for a number of carbs based on a number of sets, but I don't know how accurate that would be. The best way to do it would be what Mr. X did. Get a glucometer that measures ketones as well as blood sugar and track the changes based on workout and the number of carbs you eat. Ideally, your blood sugar should be back low within 20-30 minutes of your workout, and you should begin to see ketones within a couple of hours. I know I didn't answer your question exactly the way you hoped, but I just don't think that is possible. Everyone's a little different and some trial and error is probably the only way to get it right. The numbers Mr. X posted would probably be a good guideline to start with, and then work from there. Just do a search either on my ID or on TKD and you should get the thread. There aren't many posts in it. Good luck.
