High Blood Glucose May Stoke Hunger
You may feel less satisfied after eating a meal while blood glucose runs high, suggests a small study in people without diabetes. On one day, researchers used intravenous glucose to raise blood glucose levels of 10 overweight or obese adults by an extra 200 mg/dl. Then, on another day, the participants’ blood glucose levels were left alone. Participants ate the same meals on both days, but they reported feeling less full after eating meals on the day their blood glucose was high than when their levels were normal. Researchers say that might be because ghrelin—a hormone that triggers hunger—rose along with blood glucose.
