What happens in the fasting phase when levels of insulin are low?
What will be an ideal response?
Glucose has difficulty entering most body cells; thus, glucose stops being the body's primary fuel
In effect, this saves the body's glucose for the brain, because insulin is not required for glucose to enter most brain cells
The low levels of insulin also promote the conversion of glycogen and protein to glucose (gluconeogenesis)
