Generally, your blood glucose levels should be between 140 and 180 mg/dL immediately after eating. However, this is a general range, and the actual level can vary depending on several factors, including the type and amount of food consumed.
Factors Affecting Post-Meal Blood Sugar Levels
Several factors influence how high your blood sugar rises after a meal:
- Type of food: Carbohydrate-rich foods cause a more significant rise in blood sugar than protein or fat-rich foods. The glycemic index (GI) and glycemic load (GL) of foods are useful indicators of their potential to raise blood sugar.

- Amount of food: Larger portions of food lead to higher blood sugar increases.
- Individual metabolism: How efficiently your body processes glucose varies from person to person.
- Physical activity: Exercise helps regulate blood sugar levels. [Source: https://www.cdc.gov/diabetes/treatment/index.html]
- Underlying health conditions: Conditions like diabetes significantly impact blood sugar regulation.
Post-Meal Blood Sugar Targets
While 140-180 mg/dL is a general guideline, the International Society for Paediatric and Adolescent Diabetes (ISPAD) suggests a target range of 5.0-10.0 mmol/L (approximately 90-180 mg/dL) after meals.

It's crucial to consult with your doctor or a healthcare professional to determine appropriate target ranges for your individual situation.
Some studies show that one-hour post-meal glucose averages between 121-123 mg/dL, while three-hour post-meal values are around 97-114 mg/dL. [Source: https://www.levels.com/blog/what-should-my-glucose-levels-be-ultimate-guide] These are average values, and individual readings may differ.
Remember, consistent monitoring and discussions with your healthcare provider are essential for maintaining optimal blood sugar levels.
