I almost fast the day prior. And no soda, or sweets, or sugar in my coffee. And I drink distilled water lots of it prior. And lots of water before test. About a quart. To much water will be a bad test result sir to dillution.
I know this is an old thread and post but I came across it in a search and want to correct something for any others who see this.
Red meat does not effect your blood sugar "the moment it hits your mouth." Dont know where the poster got this info but it's most definitely false. Sugar and carbs , no matter the source, raise your blood sugar. Red meat does not contain carbs or sugar unless you add it through marinades or condiments.
