The normal range of non-diabetics might be a good place to start. > **[Continuous Glucose Profiles in Healthy Subjects under Everyday Life Conditions...](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2769652/)** > > This study investigated continuous glucose profiles in nondiabetic subjects.Continuous interstitial glucose measurement was performed under everyday life conditions (2 days) and after ingestion of four meals with standardized carbohydrate content (50... “The highest postprandial glucose concentrations were observed after breakfast: 132.3 ± 16.7 mg/dl (range 101–168 mg/dl); peak concentrations after lunch and dinner were 118.2 ± 13.4 and 123.0 ± 16.9 mg/dl, respectively. Mean time to peak glucose concentration was between 46 and 50 minutes. After ingestion of standardized meals with fast absorption characteristics, peak interstitial glucose concentrations were 133.2 ± 14.4 and 137.2 ± 21.1 mg/dl, respectively. Meals with a higher fiber, protein, and fat content induced a smaller increase and a slower decrease of postprandial glucose concentrations with peak values of 99.2 ± 10.5 and 122.1 ± 20.4 mg/dl, respectively.” There were only 24 people in the study, but I thought it was interesting. These are probably the best ranges to aim for. I have less insulin sensitivity in the morning too, so I avoid carbs at that time of day. --- _[View the full topic](https://forum.fudiabetes.org/t/spiking-after-breakfast-long-pre-bolus/3448)._
