What can i do to keep my blood sugar up and what is a healthy blood sugar level?

Eat healthy/exercise: Most of the foods you consume is metabolized/changed into sugar (glucose) for body to use (similar to oil refining to gas u use for cars), but the sugar level is nicely regulated to about 60-100 in fasting state. If you are well and eating a healthy, balanced diet, along with regular exercise, your body will regulate your sugar. If you have trouble with low or high sugar, consult doc. Good luck.

Meat and veggies : Eat only meat or fish or cheese or eggs or poultry and low starch veggies, drink only water. In other words avoid all carbs, carbs will only briefly raise your sugar levels and then you will get hungry again. The fats in the meat or fish or cheese or eggs or poultry will act like a "log on your metabolic fire" to keep your blood sugar stable for hours . Healthy blood sugar 90-99.
