The Claim

Gestational weight gain and changes in adiposity measures between the early second and third trimesters are not associated with the risk of gestational diabetes in obese women, indicating that metabolic dysfunction precedes significant pregnancy-related fat accumulation.

In plain English

In obese pregnant women, increases in body fat during the second and third trimesters do not correlate with the development of gestational diabetes, suggesting that metabolic changes occur before substantial weight gain.

See the scientific wording

Gestational weight gain and changes in adiposity measures between early second and third trimesters are not associated with gestational diabetes risk in obese women, suggesting that metabolic dysfunction predates significant pregnancy-related fat accumulation.

Why this might work

Before pregnancy, excess fat tissue in obese women is already stressed and releases substances that block insulin action. This makes the body unable to use blood sugar properly, even before more fat is gained during pregnancy. The liver and muscles then struggle to respond to insulin, leading to high blood sugar and gestational diabetes without needing further weight gain.

  1. Study: Gestational diabetes in women with obesity; an analysis of clinical history and simple clinical/anthropometric measures

    In obese pregnant women, how much weight or fat they gain during pregnancy doesn’t raise their risk of gestational diabetes — their risk is already set by factors like body fat and blood pressure early on, even before they gain much weight.
