The Claim
Long-term intake of saccharin and aspartame is associated with greater increases in body weight, waist circumference, and BMI over a 25-year period, whereas intake of sucralose is not consistently associated with changes in adipose tissue volume or anthropometric measures.
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.
Over 25 years, people who consumed saccharin or aspartame experienced greater increases in body weight, waist size, and BMI compared to those who did not, while sucralose consumption showed no consistent pattern of change in body fat or measurements.
See the scientific wording
Saccharin and aspartame intake is associated with greater increases in body weight, waist circumference, and BMI over 25 years, while sucralose intake shows no consistent association with adipose tissue volume or anthropometric change.
When people consume saccharin or aspartame over a long time, these substances change the gut environment, weaken the barrier that keeps bacteria out of the bloodstream, and cause bacterial toxins to enter the body. This triggers constant low-level inflammation that forces fat cells to grow larger and multiply, leading to more fat storage in the belly, between muscles, and under the skin. Sucralose does not trigger this process.
What the research says
1 studyPeople who drank diet sodas with saccharin or aspartame over 25 years tended to gain more weight and get bigger around the waist, but those who drank sodas with sucralose didn’t show the same pattern.
