The Claim

In Japanese adults with type 2 diabetes, lower serum bilirubin concentrations are significantly associated with higher visceral fat area, independent of age, sex, and other metabolic factors.

In plain English

In Japanese adults with type 2 diabetes, people with lower levels of bilirubin in their blood tend to have more fat around their internal organs, even after accounting for age, sex, and other metabolic differences.

See the scientific wording

In Japanese adults with type 2 diabetes, lower serum bilirubin concentrations are significantly associated with higher visceral fat area, independent of age, sex, and other metabolic factors, suggesting bilirubin may play a role in regulating abdominal fat distribution in metabolic disease.

Why this might work

Lower levels of bilirubin allow more oxidative stress in fat tissue around the organs, which triggers inflammation and causes fat cells to grow larger and release harmful signals that worsen insulin resistance. When bilirubin is present, it blocks the production of reactive molecules that cause this stress, reduces inflammation, and keeps fat cells smaller and healthier, preventing excess belly fat buildup.

  1. Study: Bilirubin reduces visceral obesity and insulin resistance by suppression of inflammatory cytokines

    People with type 2 diabetes who have less bilirubin in their blood tend to have more fat around their organs, and when scientists gave mice a substance that turns into bilirubin, their belly fat and inflammation went down — suggesting bilirubin might help control where fat is stored.
