About this study

Official title: Randomized Feasibility Trial of Isocaloric Navy-Bean Substitution in Adults With MASLD (Metabolic Dysfunction-Associated Steatotic Liver Disease)

This study is a 24-week randomized crossover feasibility trial evaluating an isocaloric navy-bean dietary substitution in 40 adults with metabolic dysfunction-associated steatotic liver disease (MASLD) and intermediate-stage (F2-F3) fibrosis. Participants are randomized to one of two sequences-habitual diet followed by a navy-bean-rich diet, or a navy-bean-rich diet followed by habitual diet-with each 12-week phase guided by registered dietitians so that navy beans replace an equivalent caloric load without changing total energy intake. The primary aim is to establish feasibility and acceptability, measured by recruitment and retention, adherence with biomarker (plasma pipecolic-acid) concordance, and patient acceptability.

Read the detailed description

Rationale: Diet acts on MASLD progression through the gut-liver axis, in which microbial composition, intestinal barrier integrity, and microbe-derived metabolites influence hepatic inflammation, steatosis, and fibrosis. Navy beans supply fermentable fiber, resistant starch, and polyphenols that nourish short-chain-fatty-acid-producing microbes, and prior human work (the BE GONE trial) demonstrated increased microbial diversity, enrichment of beneficial taxa, and favorable metabolomic and proteomic shifts following an 8-week navy-bean intervention. An isocaloric substitution approach isolates bean-specific biologic effects from weight change, addressing a major confounder in MASLD dietary trials.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Dietary Supplement/Behavioral: Navy Bean-Rich DietOther

    Also called Navy Bean-Rich Diet

    Isocaloric substitution in which navy beans replace an equivalent caloric load of the habitual diet under individualized registered-dietitian counseling, with resting-metabolic-rate-based prescription and a gradual dose ramp-up (½ to 1 cup). Total energy intake is maintained.

  • Habitual Diet (Control)Other

    Participants maintain their usual diet without the navy-bean substitution during the assigned control period

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Feasibility composite score

    Feasibility is assessed as a composite of three pre-specified measure

    1. Recruitment velocity: number of participants randomized per month, calculated as total randomized divided by months of active enrollment.
    2. Retention at Week 24: proportion of randomized participants completing both 12-week crossover periods and the Week-24 visit within the protocol window, calculated as number retained divided by number randomized.
    3. Adherence with biomarker concordance: proportion of participants achieving ≥75% of prescribed navy-bean servings during the navy-bean phase with plasma pipecolic-acid concordance, calculated as number adherent-and-concordant divided by number evaluable.

    Each component is scored 0 (below threshold), 1 (intermediate), or 2 (meets target) against pre-specified progression criteria, and the three are summed. The composite score ranges from 0 to 6, with higher scores indicating greater feasibility.

    Measured: Week 24

Secondary outcomes (5)
  1. Proportion of participants rating the navy-bean intervention as acceptable

    Proportion of participants rating the navy-bean intervention as acceptable, defined as a score ≥4 on a 5-point Likert scale (minimum 1 = least acceptable, maximum 5 = most acceptable; higher scores indicate greater acceptability) assessing taste, tolerability, and convenience.

    Measured: At Week 12 and Week 24

  2. Proportion of visits with Isocaloric fidelity

    Proportion of visits at which energy intake is within ±5% of the prescribed target with body-weight change ≤2% per period, calculated from dietary recalls and serial weights. Higher values indicate better maintenance of isocaloric substitution.

    Measured: through Week 24

  3. Change in hepatic fat by MRI-PDFF

    Within-person difference in hepatic fat, measured as MRI proton density fat fraction (percent) from blinded central reads, comparing the navy-bean condition to the habitual condition. Lower MRI-PDFF indicates less hepatic steatosis.

    Measured: Baseline (Week 0), Week 12, and Week 24

  4. Change in alanine aminotransferase (ALT)

    Serum ALT (U/L) levels. Lower ALT indicates less hepatocellular injury.

    Measured: Baseline (Week 0), Week 12, and Week 24

  5. Change in liver stiffness by MRE

    Liver stiffness (kPa) by magnetic resonance elastography. Lower stiffness indicates less fibrosis burden.

    Measured: Baseline (Week 0), Week 12, and Week 24
