The fat around your organs has four times more receptors that respond to stress hormones than the fat under your skin — which might explain why belly fat is harder to lose when you're stressed.

Appropriate Language Strength
definitive
Can make definitive causal claims
Assessment Explanation
This is a precise quantitative comparison between two tissue types that can be measured directly via molecular biology techniques (e.g., receptor binding assays, qPCR, immunohistochemistry). Multiple peer-reviewed studies have quantified glucocorticoid receptor density in human adipose depots, supporting the feasibility of such a claim. The use of 'four times' implies a measurable, reproducible ratio, which is within the scope of direct experimental quantification. No causal or speculative language is used, so the claim is appropriately stated with definitive verb strength.
More Accurate Statement
“Visceral adipose tissue expresses a fourfold higher density of glucocorticoid receptors compared to subcutaneous 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)
Characterization of regional and gender differences in glucocorticoid receptors and lipoprotein lipase activity in human adipose tissue.
Scientists measured how many glucocorticoid receptors are in belly fat vs. under-the-skin fat and found belly fat has about four times as many — just like the claim says.
Contradicting (1)
Glucocorticoid receptors in human preadipocytes: regional and gender differences.
The study found that visceral fat actually has fewer glucocorticoid receptors than subcutaneous fat in women, not more — so the claim that it has four times more is wrong.
