Best Answer: Normal Fasting Blood Sugar A normal fasting blood sugar (which is also the blood sugar a normal person will see right before a meal) is: 83 mg/dl (4.6 mmol/L) or less. Many normal people have fasting blood sugars in the mid and high 70 mg/dl (3.9 mmol/L) range.ost-Meal Blood Sugar (Postprandial) Independent of what they eat, the blood sugar of a truly normal person is: Under 120 mg/dl (6.6 mmol/L) one or two hours after a meal. Most normal people are under 100 mg/dl (5.5 mmol/L) two hours after eating. Take care Tin. Source(s): Tin S Â· 5 years ago.
