The Claim

In overweight/obese, nondiabetic women, insulin-mediated suppression of free fatty acid release is most detectable at a low-dose insulin infusion rate of approximately 15 µU/mL, while insulin-mediated glucose uptake is most apparent at a high-dose insulin infusion rate of approximately 80 µU/mL, indicating different insulin sensitivity thresholds in adipose and skeletal muscle tissues.

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

In overweight or obese women without diabetes, insulin suppresses fat release from fat tissue most effectively at a low dose, and it increases glucose uptake in muscle most effectively at a high dose, showing that fat and muscle tissues respond to insulin at different concentrations.

See the scientific wording

In overweight/obese, nondiabetic women, the ability of insulin to suppress free fatty acid release is most clearly detectable during low-dose insulin infusion (~15 µU/mL), whereas differences in insulin-mediated glucose uptake are most apparent during high-dose insulin infusion (~80 µU/mL), indicating distinct insulin sensitivity thresholds for adipose and muscle tissues.

Why this might work

In overweight women, fat cells become less responsive to insulin, so they keep releasing fat into the blood even when insulin is present. This excess fat builds up in muscle cells and blocks insulin's ability to pull sugar out of the blood. Muscle cells then need much more insulin to respond, while fat cells respond to much less.

    In overweight women without diabetes, insulin stops fat release best at low doses, but helps muscles absorb sugar best at high doses — showing fat and muscle cells need different amounts of insulin to work well.
