The Dangers Of Skipping Meals When You Have Diabetes

It's tempting -- and even sounds logical -- to skip meals: You're busy, you're not hungry, you're trying to lose weight, or your blood sugar is too high. Skipping meals, however, may actually increase your blood sugar and cause you to gain weight. Here are seven rewards of eating regularly scheduled meals when you live with diabetes. Reward 1: Improve fasting blood glucose numbers. During sleep, when you're not eating, the liver sends more glucose into the blood to fuel the body.

    How can blood sugar go up without eating?
