The Claim
Higher consumption of low/no-calorie sweetened beverages is associated with a small annual increase in body weight of 0.06 kg/year in adults aged 18–89, as observed across five European cohort studies, independent of caloric intake.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who drink more low- or no-calorie sweetened beverages gain a small amount of weight each year—about 0.06 kilograms—regardless of how few calories these drinks contain.
See the scientific wording
Higher consumption of low/no-calorie sweetened beverages is associated with a small annual increase in body weight (0.06 kg/year) in adults aged 18–89 across five European cohort studies, despite their negligible caloric content, suggesting a complex relationship not explained by energy intake alone.
When sweet-tasting substances hit the tongue and gut, they trigger signals to the brain that make the body expect sugar. When no sugar arrives, the brain keeps signaling for more food, especially sweet things, leading to eating more calories overall.
What the research says
1 studyPeople who drink more diet sodas tend to gain a tiny bit of weight each year, even though these drinks have no calories — and this study found that same pattern in over 80,000 adults across Europe.
