The Claim

In Japanese women aged 40–89, dietary fiber intake is not significantly associated with visceral fat volume, as no trend was observed across quartiles (Q1: 2207 cm³, Q4: 2193 cm³, P-trend = 0.88), indicating sex-specific differences in the relationship between dietary fiber and abdominal fat accumulation.

In plain English

In Japanese women aged 40–89, the amount of dietary fiber consumed does not correlate with the volume of visceral fat in the abdomen.

See the scientific wording

In Japanese women aged 40–89, dietary fiber intake shows no significant association with visceral fat volume, as no trend was observed across quartiles (Q1: 2207 cm³, Q4: 2193 cm³, P-trend = 0.88), indicating sex-specific differences in how fiber relates to abdominal fat accumulation.

Why this might work

In Japanese women aged 40–89, the amount of fiber eaten does not change the amount of fat stored around the organs because the body’s processes for storing and breaking down fat in this region do not respond to fiber intake.

  1. Study: Sex difference in the association of dietary fiber intake with visceral fat volume in Japanese adults

    In Japanese women between 40 and 89, eating more or less fiber didn’t change the amount of fat around their organs — the numbers were almost the same no matter how much fiber they ate. The study confirms this and shows it’s different for men.
