When both fat and insulin levels are low, the liver makes very few ketones - this finding is from an abstract summary and full study details were not available
Evidence from Studies

Community contributions welcome
Fatty acid-independent inhibition of hepatic ketone body production by insulin in humans.
The study specifically tested what happens when people have low fat levels in their blood and low insulin (about 13 units), which is exactly what the claim describes. They found ketone production was 0.70 units, matching the claim perfectly.
