- Bipolar disorder and depression affect tens of millions globally, long treated as strictly brain-based illnesses, yet both consistently show high rates of insulin resistance and metabolic disturbances
- A 2025 Nature Neuroscience study found that pancreatic insulin release and hippocampal activity are linked through a circadian feedback loop. This suggests bipolar mood shifts arise from disrupted metabolism, not brain chemistry alone
- Earlier research in 2022 showed lithium stabilizes mood partly by restoring insulin signaling, while a clinical trial found metformin improved both insulin sensitivity and psychiatric symptoms in treatment-resistant bipolar depression patients
- Insulin resistance is extremely widespread, with around 40% of Americans affected, driven by refined sugars, seed oils, stress, sleep loss, and environmental exposures that disrupt the body's natural energy regulation
- Supporting insulin sensitivity involves stepwise changes, replacing damaged fats and ultraprocessed foods, introducing gut-friendly carbs and fibers gradually, managing stress, improving sleep, and staying active to stabilize both metabolic and mental health
