Hi what she means is: 11/12-Dinner on the 12th
11/13-Breakfast on the 13th
I have done this for several months and will NEVER go back to the old way. Sometimes we eat out for Dinner on the impulse and this is really helpful because I always eat a low point breakfast and lunch.Once you start I know you will love it. Just pick a day and go. Best of luck and hope this helps. Let us know how you are doing.
