In plain English

People who drink more sugar-sweetened beverages gain a small amount of weight and waist size each year compared to those who drink less, based on data from five European studies.

See the scientific wording

Higher consumption of sugar-sweetened beverages is associated with a small annual increase in body weight (0.02 kg/year) and waist circumference (0.03 cm/year) in adults aged 18–89 across five European cohort studies, suggesting a consistent but modest link between sugary drink intake and long-term weight gain.

Why this might work

When people drink sugary beverages, the liver turns the sugar into fat, the body feels less full after drinking, and people end up eating more calories than they burn, leading to slow weight gain over time.

  1. Study: Sugar and low/no-calorie-sweetened beverage consumption and associations with body weight and waist circumference changes in five European cohort studies: the SWEET project

    People who drink more sugary drinks each day tend to gain a tiny bit of weight and waist size over time—about 20 grams per year—just like the claim says. This was found by studying over 80,000 adults across Europe.
