I have just been reading a couple of articles I found on the 'tinternet' in relation to using your BGM as a fuel gauge.
Basically you test your BG and only eat when your testing 'set point' is below your predetermined personal score..... thats when you eat.
So for talk sake lets say your BG set point is 5.0 .
You test and your 5.8 . You dont eat
Lets say you test and your 4.8. You eat. (Only if hungry)
Here are a couple of links I found, it sounds interesting to me
