Penurunan massa dan kekuatan otot dapat mulai terjadi sejak usia dewasa dan dipengaruhi oleh rendahnya aktivitas fisik serta asupan protein yang tidak memadai. Oleh karena itu, diperlukan strategi promotif dan preventif yang mengombinasikan edukasi gizi dengan latihan fisik. Penelitian ini bertujuan menganalisis perubahan asupan protein, massa otot, dan kekuatan otot setelah pemberian edukasi gizi tinggi protein berbasis media sosial yang dikombinasikan dengan latihan resistensi. Penelitian menggunakan desain quasi-experimental one-group pretest-posttest yang melibatkan 18 wanita berusia 32–50 tahun. Intervensi dilaksanakan selama 8 minggu dengan latihan resistensi sebanyak 2–3 kali per minggu. Asupan protein diukur menggunakan 24-hour food recall, massa otot menggunakan bioelectrical impedance analysis, dan kekuatan otot menggunakan handgrip dynamometer. Hasil penelitian menunjukkan bahwa rerata asupan protein meningkat dari 0,83 ± 0,05 menjadi 1,25 ± 0,06 g/kgBB/hari, massa otot meningkat dari 36,54 ± 0,97 menjadi 38,32 ± 1,08 kg, dan kekuatan otot meningkat dari 21,38 ± 0,80 menjadi 25,08 ± 1,15 kg. Seluruh variabel menunjukkan perbedaan signifikan antara pre-test dan post-test (p < 0,001). Disimpulkan bahwa kombinasi edukasi gizi tinggi protein berbasis media sosial dan latihan resistensi berpotensi meningkatkan asupan protein, massa otot, dan kekuatan otot pada wanita dewasa.
