The Claim
Diet soda consumption is not associated with increased visceral fat or visceral-to-subcutaneous fat ratio in middle-aged adults, but is associated with higher subcutaneous fat volume.
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.
In middle-aged adults, drinking diet soda is linked to higher amounts of fat under the skin but not to increased fat around internal organs or a higher ratio of internal to skin fat compared to no diet soda consumption.
See the scientific wording
Diet soda consumption is not associated with increased visceral fat or visceral-to-subcutaneous fat ratio in middle-aged adults, but is associated with higher subcutaneous fat volume, suggesting different effects on fat distribution compared to sugar-sweetened beverages.
When fructose from sugary drinks enters the liver, it turns into fat, which makes the liver resistant to insulin. This insulin resistance reduces the ability of fat under the skin to store fat, so excess fat gets pushed into the area around organs instead. Diet soda does not contain fructose, so this process does not happen, and fat stays under the skin without increasing around organs.
What the research says
1 studyPeople who drink diet soda don’t tend to have more fat around their organs, but they do have more fat just under the skin — unlike people who drink sugary sodas, who get more dangerous organ fat. So diet soda and sugary soda affect where fat is stored in different ways.
