The Claim

In overnight-fasted healthy adults, elevated circulating free fatty acids from 0.73 to 1.53 mmol/L under low insulin conditions (~13 μU/ml) more than double hepatic ketone body production from 3.6 to 8.2 μmol·kg⁻¹·min⁻¹.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

When healthy adults haven't eaten overnight and have low insulin levels, having higher levels of fatty acids in their blood (about double the normal amount) makes their liver produce more than twice as many ketone bodies - the molecules your body makes when breaking down fat for energy.

Elevated free fatty acids from 0.73 to 1.53 mmol/l during low insulin conditions (~13 μU/ml) more than double hepatic ketone body production from 3.6 to 8.2 μmol·kg⁻¹·min⁻¹ in overnight-fasted healthy adults

What the research says

1 study
  1. Study: Fatty acid-independent inhibition of hepatic ketone body production by insulin in humans.

    The study gave people extra fats (through an IV) to raise their blood fat levels while keeping insulin low, then measured how much ketone their livers produced. The results matched exactly what the claim said - raising fats from 0.73 to 1.53 mmol/L more than doubled ketone production from 3.6 to 8.2 units.
