If I were you I would not worry about the calorie issue. This is for people who have been around for a while and are now at the point where they feel they need to watch the calories more to get the scale moving. Just count the carbs and you will do great!

I have figured out an addapiton to the 10 to 12 times rule. I think you should not go below you goal weight in calories. That way you won't go into starvation mode. And do no go above the goal range. You can play around anywhere in that range to find what works for you.
