The Claim

Among obese adults treated with tirzepatide or semaglutide, White individuals have a higher proportion of achieving ≥15% weight loss compared to Black or Hispanic individuals, with 91.2% of high responders being White, 6.0% Black, and 1.6% Hispanic.

Description
1 study reviewed
In plain English

In obese adults using tirzepatide or semaglutide for weight loss, 91.2% of those who lost at least 15% of their body weight are White, while 6.0% are Black and 1.6% are Hispanic.

See the scientific wording

Among obese adults, White individuals are more likely than Black or Hispanic individuals to achieve high weight loss (≥15%) with either tirzepatide or semaglutide, with 91.2% of high responders being White compared to 6.0% Black and 1.6% Hispanic for tirzepatide, suggesting racial disparities in treatment response.

Why this might work

The body breaks down these weight-loss drugs at different rates depending on genetic traits, and the receptors they target respond differently in some people, leading to less appetite suppression and fat loss in certain groups.

What the research says

1 study
  1. Study: Weight-loss dynamics with tirzepatide versus semaglutide

    The study says White patients tended to lose more weight than Black or Hispanic patients on these drugs, but it doesn’t give the exact numbers the claim uses—so those numbers can’t be trusted even if the general trend might be real.
