The Claim
Diet beverage consumption is associated with 10–15% higher volumes of visceral, intermuscular, and subcutaneous adipose tissue and an increased risk of obesity.
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 diet beverages have higher amounts of fat around internal organs, between muscles, and under the skin, and are more likely to be obese.
See the scientific wording
Diet beverage consumption is associated with 10–15% higher volumes of visceral, intermuscular, and subcutaneous adipose tissue and increased risk of obesity, suggesting these beverages may be a primary source of artificial sweeteners driving adiposity outcomes.
When artificial sweeteners like aspartame are consumed, they break down in the gut and reduce the activity of an enzyme that normally neutralizes bacterial toxins. This allows toxins to leak into the bloodstream, triggering chronic low-level inflammation that causes fat cells to grow larger and multiply, increasing fat deposits around organs, muscles, and under the skin.
What the research says
1 studyPeople who drank diet sodas over many years ended up with more fat around their organs and muscles, and were more likely to become obese—even when researchers accounted for how much they ate or how healthy their diet was. This suggests diet sodas might contribute to weight gain in ways we don’t fully understand yet.
