The Claim

Consumption of sugar-sweetened beverages is associated with an increased risk of type 2 diabetes, and this association is partially mediated by weight gain, as evidenced by a reduction in relative risk from 1.83 to 1.39 after adjustment for body mass index.

How it works
1 study reviewed
In plain English

People who drink sugar-sweetened beverages regularly have a higher risk of developing type 2 diabetes, and part of this increased risk is explained by weight gain.

See the scientific wording

The association between sugar-sweetened beverage consumption and type 2 diabetes risk is partially mediated by weight gain, as adjusting for body mass index attenuated the relative risk from 1.83 to 1.39, suggesting that excess calories from these beverages contribute to diabetes through obesity.

Why this might work

Drinking sugary beverages adds extra calories that the body does not compensate for by eating less food. These extra calories are stored as fat, especially around the liver and muscles. The fat releases chemicals that block insulin from working properly, so blood sugar stays high. The pancreas works harder to make more insulin until it can no longer keep up, leading to permanently high blood sugar and type 2 diabetes.

What the research says

1 study
  1. Study: Sugar-sweetened beverages, weight gain, and incidence of type 2 diabetes in young and middle-aged women.

    This study found that women who drank more sugary drinks gained more weight and were more likely to get type 2 diabetes. When they gained weight, their diabetes risk went up, which suggests that gaining weight from sugary drinks is one reason why these drinks increase diabetes risk.
