Increased appetite during a depressive episode is the primary driver of associations between depression and metabolic/inflammatory markers (BMI, metabolic syndrome components, waist circumference, CRP, TNF-α).

If you are depressed and experiencing increased appetite, this is a specific biological subtype ('immuno-metabolic depression') linked to higher inflammation and metabolic risk. It is not just 'overeating' but a symptom. Standard antidepressants may not address this. Discuss with your doctor whether treatments targeting inflammation (like anti-inflammatories or statins, though evidence is mixed) or lifestyle interventions (diet, weight loss) might be beneficial for this specific subtype.

GoodSupportsHIGH confidence
Increased appetite – in the context of a depressive episode – was the only symptom that was associated with both metabolic as well as inflammatory markers, and could be a key feature of an immuno-metabolic form of depression.

Why this rating

Large sample size (N=808), rigorous diagnostic interviews, and adjustment for multiple covariates, though cross-sectional design limits causal inference.
