The Claim

Individuals who develop persistent abdominal obesity after previously being non-obese have a higher risk of early-onset colorectal cancer compared to those who remain non-obese, with a hazard ratio of 1.18, indicating that abdominal fat accumulation may be a more critical risk factor than overall weight gain.

In plain English

People who gain fat specifically around the abdomen after being previously lean have a slightly higher chance of developing colorectal cancer at a younger age than those who never gained excess weight.

See the scientific wording

Individuals who develop persistent abdominal obesity after previously being non-obese have a higher risk of early-onset colorectal cancer than those who remain non-obese, with a hazard ratio of 1.18, suggesting abdominal fat accumulation may be a more critical risk factor than overall weight gain.

  1. Study: Association of changes in obesity and abdominal obesity status with early-onset colorectal cancer risk: a nationwide population-based cohort study

    People who gained belly fat and kept it, even if they weren’t overall overweight, were 18% more likely to get colon cancer before age 50 than people who never had extra belly fat. This suggests belly fat is more dangerous than just gaining weight in general.
