Gangguan psikiatri meningkatkan risiko penderitanya mengalami obesitas dan sindroma metabolik akibat interaksi faktor genetik, lingkungan, gejala penyakit psikiatri dan pengobatannya. Pengaturan asupan makan dan perubahan pola hidup tetap menjadi tatalaksana awal pada pasien dengan gangguan psikiatri. Penggunaan metformin telah disarankan dalam studi sebagai adjuvan dalam tatalaksana berat badan pada pasien gangguan psikiatri terutama yang menggunakan obat psikiatri dalam jangka panjang. Empat pasien rawat inap dengan gangguan psikiatri dipantau selama perawatan dan sebulan setelah rawat jalan dengan kontak per minggu. Dilakukan pencatatan masalah subjektif, objektif, riwayat peningkatan berat badan, riwayat pengobatan pola asupan serta pengukuran antropometri dan komposisi tubuh. Pola asupan harian dan 24 jam terakhir dikumpulkan dengan metode FFQ semi kuantitatif dan 24h dietary recall. Perencanaan terapi medik gizi dilakukan dengan restriksi kalori, peningkatan asupan protein, penyesuaian asupan karbohidrat, motivasi melakukan aktivitas fisik yang cukup dan pemberian metformin dengan dosis bertahap. Tiga pasien memiliki status gizi obes 2, 1 pasien memiliki status gizi obes morbid yang disertai massa lemak yang tinggi dan massa otot yang rendah. Seluruh pasien memiliki lingkar pinggang diatas normal, kadar kolesterol total, LDL yang tinggi dan HDL yang rendah. Tiga pasien tidak mematuhi preskripsi selama perawatan. Setelah rawat jalan, dua pasien memiliki caregiver yang memberikan pemantauan dan motivasi yang baik terhadap pasien selama sebulan dan terdapat penurunan berat badan, penurunan lingkar pinggang, dan perbaikan komposisi tubuh. Terapi medik gizi pada pasien dengan gangguan psikiatri membutuhkan kerjasama dengan caregiver agar dapat bermanfaat bagi pasien.
