I received a blood glucose meter this morning, just looking for some advice using it...
I don't eat breakfast so I should do a fasting test now I think, then again after a starchy meal to see how i'm handling the carbs right? How long after the meal should I wait?
What range should my measurements be within fasting & post-prandial?
My fasting level right now is 5.1 mmol/l, which I think is decent considering i ate a considerable amount of carbs last night (150g+ net carbs) and i usually eat low carb
Does the paleo crowd differ from what they'd consider normal at the docs?
Thanks for any advice

I disagree with the previous post, you could very well be on a low carb diet and not have blood glucose below 70mg/dl. As a matter of fact the people who do low carb and have a blood glucose of less than 70mg/dl are usually the ones who just start out and switched from a high carb diet.
Normal BG for people on low carb diets is the same as for everyone else. Usually somewhere between 70 and 100 mg/dl. The reason is that when less carbs are eaten, the body over time adjust to lower carb loads by producing less insulin. It is a classic negative feedback mechanism: more glucose causes a rise in insulin which causes glucose to come down which causes insulin to come down as well ultimately resulting in a steady blood glucose level and a steady insulin level.
If you're on a low carb diet, your blood glucose should be in a normal range, your insulin however should be very, very low. You're going to get your glucose from protein (amino acids) and from fat (the glycerol). If your blood glucose is too high, eat less (especially protein), if it's too low, eat more.

Ideally you want to leave it overnight to do a fasting check. Doctors recommend no food for 12 hours. If you're checking to see how you respond to a meal, go 15-20 minutes after the meal, and then again 2 hours later.
Your fasting level should be around 4mmol/l (about 70 md/gl). After a meal could go up to around 6 mmo/l (110 md/gl) if you ate a lot of carbs. Hopefully the 2 hour check will be slightly lower than your 15 minute post meal check.
This is a good range regardless of diet. You may notice however your fasting level may be lower that 4mmol/l if you're sticking to a very low carb diet.
