Is it normal for blood sugar levels to go from 100 in the morning to 170 by eating healthy portion controlled meals? my dr wont send me to a specialists until i prove to him i can lose more weight. i told him i lost ten pounds. i am so tired?

Post-prandial blood glucose below 180 mg/dL is in the normal range. If you are not satisfied with your current doctor, it is your prerogative to consult a different one. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Wish you good health!
