When obese, men’s fat cells need 10 times more insulin to stop fat from being released into the blood than women’s fat cells, making their bodies less able to control fat levels.

Design supports claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The claim uses precise quantitative language ('10-fold lower') based on direct in vitro measurements. The study design supports association, not causation, and the verb 'have' correctly reflects observed differences.
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.

Sex differences in adipose insulin resistance are linked to obesity, lipolysis and insulin receptor substrate 1
In obese people, men’s fat cells are much less responsive to insulin’s signal to stop breaking down fat compared to women’s—by about 10 times—and this study proves it, showing why men store more fat and are more prone to metabolic problems.
