The Simplified Nutritional Appetite Questionnaire (SNAQ) assessed AA, with follow-ups at weeks 2, 4, 8, and 12. Primary outcomes were SNAQ improvements; secondary outcomes included weight, grip strength, nutritional status (BMI, MNA-SF), cognition (MMSE), mobility (SPPB), mental health (GDS15), and quality of life (EQ-5D).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Younger, non-solo-living, and malnourished participants preferred ONS intervention (<jats:italic>p<\/jats:italic>\u202f&amp;lt;\u202f0.05). Both groups showed increased SNAQ scores versus baseline (counseling: weeks 4\/8\/12; ONS: weeks 2\/4\/8\/12), with ONS achieving significantly greater improvement at week 2 (<jats:italic>p<\/jats:italic>\u202f&amp;lt;\u202f0.05).
