The Claim

In non-diabetic adults, skeletal muscle glucose uptake during insulin stimulation is strongly associated with whole-body insulin sensitivity, with a threshold of 33 µmol/kg tissue/min distinguishing insulin-resistant from insulin-sensitive individuals, and muscle glucose disposal is a primary determinant of systemic insulin sensitivity.

How it works
1 study reviewed
In plain English

In adults without diabetes, the rate at which skeletal muscle takes up glucose during insulin stimulation is directly linked to overall insulin sensitivity, and a rate of 33 µmol/kg tissue/min separates individuals with insulin resistance from those who are insulin sensitive, indicating that muscle glucose uptake is a main factor controlling whole-body insulin sensitivity.

Why this might work

When insulin is present, muscle cells pull sugar from the blood by moving special transporters to their surface. If this process is weak, sugar stays in the blood and the whole body becomes resistant to insulin. High levels of fat in the blood from fat tissue block this process in muscle and liver, making insulin resistance worse. A muscle sugar uptake rate below 33 units per minute per kilogram of tissue marks when the body can no longer manage blood sugar properly.

    In people without diabetes, how well their muscles soak up sugar when insulin is present is the best sign of how sensitive their whole body is to insulin — and if muscles take up less than 33 units of sugar per minute, they’re likely insulin resistant.
