A meta-analysis published in 2019 demonstrated that fiber administration at doses of 10 to 16 g per day (study duration between 10 and 12 weeks) resulted in favorable changes in liver-related biomarkers (insulin resistance index (HOMA-IR), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) levels) [13]. The gene discussed is GPT; the disease is Insulin resistance.
