Resumo

O objetivo deste trabalho foi analisar as evidências disponíveis sobre os efeitos de dietas com elevado teor de fibras na saciedade e no manejo nutricional da obesidade em cães idosos. Realizou-se uma revisão narrativa, descritiva e crítica da literatura, com buscas encerradas em 31 de julho de 2026 nas bases PubMed/MEDLINE e SciELO, no Google Scholar e em diretrizes profissionais de nutrição veterinária. Foram elegíveis artigos originais, revisões e diretrizes publicados entre 1996 e julho de 2026 que abordassem obesidade canina, saciedade, fibra alimentar, perda de peso, composição corporal ou particularidades nutricionais do envelhecimento. As evidências indicam que formulações de baixa densidade energética, principalmente quando associam maior teor proteico a fontes de fibra adequadamente selecionadas, podem reduzir a ingestão energética, favorecer a perda de adiposidade e contribuir para a tolerância à restrição calórica. Entretanto, a resposta varia segundo a fonte e a fermentabilidade da fibra, a densidade energética, o teor proteico, a palatabilidade, o manejo alimentar e as características individuais. Estudos recentes reforçam a necessidade de preservar massa magra e assegurar adequação de nutrientes durante o emagrecimento, sobretudo em animais mais velhos. A literatura conduzida diretamente em cães idosos obesos permanece escassa. Conclui-se que dietas de alta fibra podem integrar o tratamento da obesidade canina, mas não constituem intervenção isolada nem universal. Em cães idosos, a prescrição deve ser individualizada, nutricionalmente completa e associada ao monitoramento de peso, adiposidade, condição muscular, tolerância gastrointestinal, comorbidades e adesão do tutor.
