When rats have very high blood sugar (like in a dangerous condition called HHS), their fat cells don’t release as much fat into the blood — and that’s why they don’t make ketones, even though you’d expect them to.

Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The claim uses 'associated with,' which is appropriate for observational or mechanistic in vitro data. It does not claim causation (e.g., 'causes' or 'induces'), which is correct since the study is in isolated adipocytes — a reductionist system that cannot fully replicate whole-body hormonal and metabolic interactions in HHS. The claim is appropriately cautious and grounded in the limitations of the model. However, it should be noted that rat adipocytes may not fully mirror human adipocyte behavior in HHS.
More Accurate Statement
“In isolated rat adipocytes, the lack of ketosis observed in hyperglycemic hyperosmolar syndrome is associated with a reduced release of free fatty acids from adipose tissue.”

Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Evidence from Studies
Supporting (1)
When blood sugar and salt levels are super high (like in a serious diabetic condition), fat cells stop releasing the fatty acids needed to make ketones — so no ketones are made, even when the body should be making them.
