Scientists found that keeping insulin levels artificially high for a week made rats develop severe insulin resistance - their bodies became much worse at processing sugar, with glucose uptake dropping by 39% and sugar storage falling by 62%.

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

Cohort Study

Animal

1997 Oct

This study tested the exact same thing as the claim - giving rats insulin for 7 days while keeping blood sugar normal. The results match perfectly: insulin resistance increased by the exact percentages stated in the claim.

Similar Assertions

When the body has too much insulin floating around for too long, cells stop listening to it to protect themselves from damage. This forces the pancreas to pump out even more insulin, creating a harmful cycle.

Giving rats insulin for a week while keeping their blood sugar normal doesn't change their blood pressure.

When researchers kept insulin levels high but blood sugar normal in rats for a week, the rats' bodies didn't hold onto more sodium than usual - their sodium levels stayed steady at about 0.34 mmol.

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.
