The Claim

In sedentary individuals, insulin-mediated suppression of circulating fatty acids during hyperinsulinemia is reduced compared to active individuals, resulting in fatty acid concentrations approximately twice as high despite similar baseline levels and higher insulin concentrations.

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.

How it works
1 study reviewed
In plain English

Sedentary people have higher levels of fatty acids in their blood during periods of elevated insulin compared to active people, even when their starting fatty acid levels are the same and their insulin levels are higher.

See the scientific wording

In sedentary individuals, insulin’s ability to suppress circulating fatty acids during hyperinsulinemia is impaired, resulting in fatty acid levels approximately twice as high as in active individuals despite similar baseline levels and higher insulin concentrations, suggesting a physiological consequence of reduced adipose insulin sensitivity.

Why this might work

In sedentary people, fat cells have fewer insulin receptors and related signaling proteins, so insulin cannot effectively tell them to stop breaking down fat. This causes fat to keep leaking into the blood even when insulin levels are high, resulting in twice as many fatty acids circulating compared to active people.

  1. Study: RELATIONSHIP BETWEEN A SEDENTARY LIFESTYLE AND ADIPOSE INSULIN RESISTANCE.

    When insulin goes up, inactive people’s fat cells don’t respond well, so fatty acids stay high in their blood — even when insulin levels are higher than in active people. This happens because their fat cells are less sensitive to insulin’s signal to stop breaking down fat.
