The Claim
In mice with liver-specific deletion of both MPC2 and ALT2, endogenous glucose production is reduced at rest and during exercise due to decreased contributions from glycogenolysis and gluconeogenesis, as measured by ²H/¹³C metabolic flux analysis, indicating that mitochondrial pyruvate and alanine metabolism are necessary for full hepatic glucose output under metabolic demand.
What the research says
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.
When two specific genes are turned off in the livers of mice, their bodies make less blood sugar—both when resting and exercising—because the liver can't use certain fuel sources as well. This shows those genes are important for keeping blood sugar levels up when the body needs more energy.

What the research says
1 studyThe study looked at mice missing two liver proteins needed to process sugar and protein for energy, and found they couldn’t make enough blood sugar during rest and exercise, just like the claim says.
