The Claim

Seven days of euglycemic hyperinsulinemia does not cause elevation in plasma epinephrine (88 +/- 15 pg/ml) or norepinephrine (205 +/- 31 pg/ml) levels in conscious normal rats, with catecholamine concentrations remaining constant throughout the infusion period.

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

Scientists found that when they kept rats with normal blood sugar on high insulin for a week, their stress hormone levels didn't change at all - they stayed exactly the same.

Seven days of euglycemic hyperinsulinemia does not elevate plasma epinephrine (88 +/- 15 pg/ml) or norepinephrine (205 +/- 31 pg/ml) levels in conscious normal rats, with catecholamine concentrations remaining constant throughout the infusion period.

  1. Study: Seven Days of Euglycemic Hyperinsulinemia Induces Insulin Resistance for Glucose Metabolism but Not Hypertension, Elevated Catecholamine Levels, or Increased Sodium Retention in Conscious Normal Rats

    The study did exactly what the claim describes - gave rats seven days of high insulin while keeping blood sugar normal - and found that epinephrine and norepinephrine levels stayed the same (88 and 205 pg/ml respectively), exactly matching what the claim says.
