If you have recently been diagnosed with type 2 diabetes and you double how much sugary soda you drink, your body becomes about 2.6% less able to use insulin properly and you’re about 16–17% more likely to get fat in your liver—even if you’re not eating more calories overall.

Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The claim uses 'associated with' and explicitly controls for confounders and total energy intake, which is appropriate for observational data. It does not claim causation, nor does it overstate biological mechanisms. The effect sizes (2.6–2.7% reduction, 16–17% increased odds) are precise and plausible based on existing literature on fructose and metabolic health. The phrasing correctly reflects correlational findings from cohort or cross-sectional studies with multivariable adjustment.

Evidence from Studies
Supporting (1)
This study found that when people with recently diagnosed type 2 diabetes drink more sugary drinks (like soda), their body becomes less sensitive to insulin and they’re more likely to have fatty liver — just like the claim says.
