FGF21 is normally released into circulation by the liver in response to fasting, ethanol, exercise, ketogenic diet, simple carbohydrates (esp. fructose), refeeding, obesity, type 2 DM, and mitochondrial disease, and has multiple sites of action including specific β-klotho-expressing regions of the brain, where FGF21 functions to restrain the intake of sweets and ethanol, and the periphery, where it increases energy expenditure and body temperature.

Fasting, refeeding, ketogenic diet, simple carbohydrates, mitochondrial disease, ethanol and fructose all have direct paths to producing G3P.
