The Claim
In overweight/obese, nondiabetic women, a two-stage insulin infusion protocol using basal (~15 µU/mL) and physiological (~80 µU/mL) insulin levels quantifies adipose tissue insulin resistance through suppression of free fatty acids and muscle insulin resistance through glucose disposal within a single 4-hour test.
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.
In overweight or obese women without diabetes, a specific 4-hour insulin infusion test measures how resistant fat tissue is to insulin by tracking free fatty acid levels and how resistant muscle is to insulin by tracking glucose uptake.
See the scientific wording
In overweight/obese, nondiabetic women, the two-stage insulin infusion protocol using basal (~15 µU/mL) and physiological (~80 µU/mL) insulin levels effectively quantifies both adipose tissue insulin resistance (via FFA suppression) and muscle insulin resistance (via glucose disposal) in a single 4-hour test.
When fat cells don't respond to insulin, they keep releasing free fatty acids into the blood. These fatty acids build up in muscle cells and block insulin's ability to pull glucose out of the blood. This same fatty acid overload also prevents fat cells from stopping fat breakdown, creating a cycle where both fat and muscle tissues resist insulin at the same time.
What the research says
1 studyThis study showed that by giving two different doses of insulin and measuring fat and sugar levels in the blood, doctors can tell if a woman’s fat cells and muscles aren’t responding well to insulin—all in just four hours.
