When a mouse gets suddenly scared or stressed, its body first releases energy chemicals from muscles and fat within two minutes, and then about 15 to 30 minutes later, its liver starts making sugar to keep the energy flowing.

Impact of acute stress on murine metabolomics and metabolic flux

Cohort Study

The study shows that when mice get stressed, their bodies quickly release a lot of lactate — which matches part of the claim. It doesn't check the later glucose production phase, but what it does show supports the first part of the claim.

When you're under sudden stress, your liver quickly makes more sugar and releases it into your blood so your muscles have extra energy to react.

When mice get suddenly scared or stressed, a specific part of their brain sends a signal to their liver to quickly make more sugar, and this happens without needing their stress hormones or insulin/glucagon from the pancreas.

When you handle fasted mice suddenly, their bodies panic and burn sugar too fast in their muscles, causing a big spike in two chemicals (lactate and pyruvate) in their blood—this messes up science tests that measure metabolism using a tail blood sample.
