How it works
4 studies reviewed
In plain English

Fat tissue around internal organs releases signaling molecules that directly reduce the body's ability to respond to insulin.

See the scientific wording

Visceral adipose tissue promotes systemic insulin resistance through the secretion of pro-inflammatory cytokines and other bioactive molecules.

Why this might work

Fat around the organs releases chemicals like TNF-alpha and ceramides that block insulin's ability to tell cells to take up sugar. This causes sugar to build up in the blood. The fat also stops making protective molecules like adiponectin, which normally helps insulin work. These changes happen even before immune cells move in, and they spread to muscle and liver, making the whole body less responsive to insulin.

What the research says

4 studies

  1. Study: Interleukin-10 expressing B lineage cells in visceral adipose tissue protect against aging-related insulin resistance and extend lifespan

    Fat around the organs releases signals that can make the body less responsive to insulin, and this study shows that some signals from that fat (like IL-10) actually help fix that problem — proving the fat is actively sending messages that affect insulin.

  2. Study: The Roles of Adipokines, Proinflammatory Cytokines, and Adipose Tissue Macrophages in Obesity-Associated Insulin Resistance in Modest Obesity and Early Metabolic Dysfunction

    Fat around the organs releases chemicals that make the body less responsive to insulin, and this study found that one of those chemicals, TNF-α, goes up exactly when insulin resistance gets worse — even before immune cells show up.

  3. Study: Molecular tracking of insulin resistance and inflammation development on visceral adipose tissue

    Fat around the organs in obese people releases chemicals that make the body less responsive to insulin, and this study shows exactly how that happens through inflammation and immune cell changes.

  4. Study: Black African men with early type 2 diabetes have similar muscle, liver and adipose tissue insulin sensitivity to white European men despite lower visceral fat

    Even though Black African men had much less belly fat than White European men, their bodies responded to insulin just as well—or poorly—in every tissue tested. This means belly fat alone doesn’t always control how well insulin works.
