The Claim

In male mice, protein restriction induces mitochondrial adaptations in adipose tissue, and these adaptations are absent in FGF21-knockout mice, indicating that FGF21 is required for these metabolic changes.

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.

How it works
1 study reviewed
In plain English

When male mice are fed a low-protein diet, their fat tissue undergoes changes in mitochondrial function, but these changes do not occur if the mice lack the FGF21 protein, showing that FGF21 is necessary for the metabolic response to protein restriction.

See the scientific wording

In male mice, the mitochondrial adaptations in adipose tissue induced by protein restriction are absent in FGF21-knockout mice, suggesting FGF21 is necessary for these metabolic changes.

What the research says

1 study
  1. Study: Dietary protein restriction elevates FGF21 levels and energy requirements to maintain body weight in lean men

    When mice eat less protein, their fat cells change how they use energy, but only if they have a special protein called FGF21. If mice don’t have FGF21, those changes don’t happen — so FGF21 is needed for the change.
