The Claim

Seven days of sustained euglycemic hyperinsulinemia (insulin levels of approximately 90 mU/L, representing a threefold increase over basal levels) induces severe insulin resistance with respect to whole-body glucose metabolism in conscious normal rats, resulting in a 39% reduction in insulin-mediated glucose uptake, a 62% reduction in glucose storage, and a 26% reduction in glycolysis compared to vehicle-treated control rats.

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.

How it works
1 study reviewed
In plain English

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%.

  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

    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.
