Blood sugar levels above 120 indicate potential pre-diabetes, but levels in the 90s to low 100s may not be concerning, especially if you feel alert and productive. Engaging in physical activity or focused work can temporarily elevate blood sugar, but a lack of hunger and sustained energy suggests your body is effectively burning fat. For optimal caffeine benefits, consider waiting 90 to 120 minutes after waking before consuming caffeinated beverages, unless exercising early.
