Hey... first of all i am also in the Chicagoland Area.. scorcher today isn't it??

I would think she could eat 20 carbs per per 24 hours... so if she is starts at a certain time... and is still up when the 24hrs is up... she would be able to eat some more carbs at that time and count it towards the next day.... it might take some adjustment.. but if she is losing weight then it is working right?? have her try the Ketone strips..

Good luck...
