The Claim

In overweight/obese, nondiabetic women, plasma free fatty acid concentrations during basal insulin conditions are not correlated with body mass index but are strongly correlated with insulin-mediated glucose disposal, indicating that insulin resistance, rather than obesity alone, is associated with elevated free fatty acid levels.

In plain English

In overweight or obese women without diabetes, high levels of free fatty acids in the blood during normal insulin conditions are linked to how well the body uses insulin to absorb glucose, not to how much body fat they have.

See the scientific wording

In overweight/obese, nondiabetic women, plasma free fatty acid concentrations during basal insulin conditions are not correlated with body mass index (BMI), but are strongly correlated with insulin-mediated glucose disposal, suggesting that insulin resistance—not obesity alone—drives elevated free fatty acid levels.

Why this might work

When insulin cannot properly signal in fat cells, those cells keep releasing fat into the blood even when insulin is present. This excess fat in the blood interferes with muscle cells' ability to take in sugar, which makes the muscle resistant to insulin. The same insulin signaling problem that causes fat cells to leak fat also causes muscle cells to resist sugar uptake, so high fat levels and poor sugar control happen together and are not caused by body weight alone.

    In overweight women without diabetes, how much fat is in their blood when insulin is low isn't about how much they weigh, but about how well their body uses insulin to soak up sugar—worse insulin response means more fat in the blood.
