The Claim

Consumption of sugar-sweetened beverages is associated with increased insulin resistance independent of changes in body mass index.

Source: Sugar-Sweetened Beverage but Not Diet Soda Consumption Is Positively Associated with Progression of Insulin Resistance and Prediabetes.

In plain English

People who drink sugar-sweetened beverages have higher insulin resistance than those who do not, even when their body weight is the same.

See the scientific wording

The association between sugar-sweetened beverage consumption and increased insulin resistance persists after adjusting for changes in body mass index, suggesting that the metabolic impact of added sugars may extend beyond weight gain.

Why this might work

When people drink sugary beverages, the liver turns the sugar into fat, and this fat builds up inside liver cells. This fat blocks the signals that tell the liver to stop making glucose and to take up sugar from the blood. As a result, the liver keeps releasing too much glucose into the bloodstream, and the body’s cells become less responsive to insulin, leading to high blood sugar and insulin resistance.

  1. Study: Sugar-Sweetened Beverage but Not Diet Soda Consumption Is Positively Associated with Progression of Insulin Resistance and Prediabetes.

    Even when people don’t gain weight, drinking sugary sodas still makes their bodies worse at handling sugar, which can lead to diabetes. This study shows sugar itself, not just weight gain, is the problem.
