The Claim

In nondiabetic, moderately obese adults with BMI 25-35 kg/m², insulin-resistant individuals have significantly lower rates of triglyceride synthesis and de novo lipogenesis in subcutaneous adipose tissue compared to insulin-sensitive individuals, while adipocyte proliferation rates are not different between the two groups, resulting in reduced fat storage capacity and elevated circulating free fatty acids.

How it works
1 study reviewed
In plain English

In moderately obese adults without diabetes, those with insulin resistance have reduced fat storage activity in their subcutaneous fat tissue compared to those without insulin resistance, while fat cell numbers remain the same, leading to higher levels of free fatty acids in the blood.

See the scientific wording

In nondiabetic, moderately obese adults with BMI 25-35 kg/m², insulin-resistant individuals exhibit significantly lower rates of triglyceride synthesis and de novo lipogenesis in subcutaneous adipose tissue compared to insulin-sensitive individuals, while adipocyte proliferation remains unchanged, suggesting a specific impairment in fat storage capacity that may contribute to elevated circulating free fatty acids and insulin resistance.

Why this might work

In obese people who are insulin resistant, their fat cells under the skin cannot turn sugar into fat or store fat properly. This causes too much fat to spill into the blood. The excess fat then builds up in the liver and muscles, where it blocks the signals that tell the body to respond to insulin. As a result, the body becomes less able to control blood sugar.

    In moderately obese people, those with insulin resistance can't store fat as well in their under-skin fat tissue, even though they have the same number of fat cells as others. This causes more fat to leak into the blood, which makes insulin resistance worse.
