Readers who start “The Personalized Diet,” often begin testing their blood to check how specific foods affect their sugar levels. Dieters who have never tested their blood sugar before, understandably, have questions. One question recently came into The Personalized Diet Facebook page and Dr. Segal answered.
Ken asks: Is it normal for my blood sugar to be higher in the morning after fasting, than it was the night before when I took my last reading?
Dr. Segal: Yes, it is normal. While blood glucose levels mainly change after meals, they also fluctuate (albeit to a lesser extent) during the day. The levels should generally be lower than after meals.
