PYY3-36 and GLP-1 appetite-suppressing effects were unreliable in non-acclimatized mice, explaining conflicting published results — proper experimental conditions are essential for valid appetite peptide research.

What the researchers found
PYY3-36 and GLP-1-mediated appetite suppression required proper mouse acclimatization and habituation to experimental conditions; non-acclimatized mice showed variable, unreliable anorectic responses — explaining conflicting literature results.
Why it matters
