Mental disorders show substantial inter-individual variability in treatment responsiveness and clinic al course even within the same diagnostic category. Such variability may be associated not only with biological, psychological, and social factors but also with lifestyle-related factors. This review outlined the Bio-Psycho-Social-Lifestyle (BPSL) model, which explicitly incorporated lifestyle (Lif estyle) into the conventional Bio-Psycho-Social model, and discussed its significance for personaliz ed psychiatric care. Nutritional psychiatry may be reasonably positioned as a supportive approach t hat may enhance the effects of established treatments such as pharmacotherapy and psychotherapy, potentially via mechanisms including anti-inflammatory effects, neuroplasticity, and the gut-brain re lationship. With accumulating epidemiological and interventional studies, associations between dieta ry patterns and mental disorders have been increasingly reported; however, careful clinical applicati on is required at present as a complementary treatment. Integrating systematic lifestyle assessment based on the BPSL model may provide an important perspective for the further development of p ersonalized psychiatric care.
