WOD – Understanding Glucose

glucose

Let’s talk about homeostasis and how your body uses glucose, insulin and glucagon to regulate. 🎙 @leahpolaski 📼 2 mins

Glucose: Spend it or store it?

Glucose can be used for energy (adenosine triphosphate) or stored as glycogen (polysaccharide storage molecule) or adipose (fatty) tissue. The body uses the hormones insulin and glucagon to manage this process and stabilize blood sugar for health and performance.

Insulin is in charge of storing glucose. Regularly eating too much—especially too many processed carbohydrates—promotes storage, and when the liver and muscles are full of glycogen, fat is created in the liver (de novo lipogenesis). This fat is typically stored around the liver, directly increasing the risk of cardiovascular diseases, metabolic syndrome, diabetes and nonalcoholic fatty liver disease (NAFLD).

Glucagon, a mobilization hormone, is counter-regulatory to insulin and released as a result of fasting or eating a very low-carbohydrate diet. Glucagon cleaves glucose from glycogen so it can be used as fuel.

Interesting Fact:
We don’t need to consume glucose to form glycogen. Glucose can be made in the liver through a mechanism called gluconeogenesis. The liver uses amino acids, glycerol and lactate to make glucose and stores it as glycogen.
