CGM has no real impact on eating, other than helping you make more intelligent decisions about taking insulin. Most insulin users count carbs, or should. Counting carbs means calculating to the best of your ability the blood sugar impact of the meal you are about to eat, then figuring out how much insulin to take to “cover” the carb load in advance, before you start eating.

Historically, you’d take a fingerstick reading before eating and either add or subtract insulin depending on whether you were above your blood sugar target or below it. But with CGM you now have context for that fingerstick. You can consider the trend over the last hour or two.

is a serious, life-long condition and the sixth leading cause of death in the United States. Diabetes is a disorder of metabolism (the body's way of digesting food and converting it into energy). There are three forms of diabetes. Type 1 diabetes is an autoimmune disease that accounts for five- to 10-percent of all diagnosed cases of diabetes. Type 2 diabetes may account for 90- to 95-percent of all diagnosed cases. The third type of diabetes occurs in pregnancy and is referred to as gestational diabetes.
