Can you please explain the function of insulin in the body?

Drives Sugar Uptake: Insulin triggers cells to ↑ sugar uptake, including fat cells. Healthy levels low, 35-45 u/24 hrs. Dietary sugars (rare in nature) stimulate Insulin release &, over time, liver+muscle cells down regulate response in order to protect themselves from the ↑ed sugar (called Insulin resistance). Chronic sugar intake ↑es both onset of type i dm & further compounds type ii dm, obesity, cvds, cancers, etc.

Insulin lowers: Blood sugar by facilitating it's entry into cells where you can utilize it for energy or by stimulating it's incorporation into fat for storage. It also triggers a cascade of metabolic pathways that lead to protein synthesis and other chemical reactions, which in excess can by harmful to your body. Keep your Insulin level down by staying lean through diet, exercise and weight loss.
