Blood Glucose
The sugar circulating in your blood — the value diabetes care manages and GLP-1 drugs steady after meals.
Blood glucose is the body's shared fuel currency, held in a narrow band by the insulin-glucagon duet. After meals it rises; how far and for how long depends on what was eaten, how fast the stomach empties, and how sensitive the tissues are to insulin.
Weight patients meet glucose mainly through its swings: sharp spikes from refined carbohydrates invite sharp dips, and dips read as hunger and cravings. GLP-1 medications flatten the ride — glucose-dependent insulin release plus slowed gastric emptying — which is why many users report steadier energy before much weight has moved. Fasting glucose and HbA1c are the lab yardsticks tracking the longer arc.
