The Claim

In overweight/obese, nondiabetic women, higher plasma free fatty acid concentrations during low-dose insulin infusion are strongly associated with higher plasma glucose concentrations during high-dose insulin infusion, with a correlation coefficient of r=0.85 (P<0.001), indicating that impaired insulin suppression of fat release from adipose tissue is closely linked to reduced insulin-stimulated glucose uptake in muscle.

In plain English

In overweight or obese women without diabetes, higher levels of free fatty acids in the blood during low insulin conditions are directly linked to higher blood glucose levels during high insulin conditions, reflecting a relationship between reduced fat suppression and reduced glucose uptake in muscle.

See the scientific wording

In overweight/obese, nondiabetic women, higher plasma free fatty acid (FFA) concentrations during low-dose insulin infusion (approximately 15 µU/mL) are strongly associated with higher plasma glucose concentrations during high-dose insulin infusion (approximately 80 µU/mL), with a correlation coefficient of r=0.85 (P<0.001), indicating that impaired insulin suppression of fat release from adipose tissue is closely linked to reduced insulin-stimulated glucose uptake in muscle.

Why this might work

When insulin is low, fat cells in overweight people release too much fat into the blood because they do not respond properly to insulin. This excess fat builds up in muscle cells, where it blocks the signal that tells the muscle to take in sugar from the blood. As a result, when insulin is raised later, the muscle cannot absorb sugar effectively, leading to high blood sugar levels.

    In overweight women without diabetes, when insulin is low, those with more fat in their blood tend to have higher sugar levels when insulin is raised — showing that how well the body controls fat and sugar are closely connected.
