@robertlufkin: Does better nutrition need a better app? In a single-center randomized trial of 80 adults, personalized menu groups lost about 6.0%-7.3% of body weight at 12 weeks, versus 2.1% with general advice (PreVA trial: https://doi.org/10.3389/fnut.2026.1815820). App coaching did not show a clear advantage over printed plans, but this small, unblinded study was not proof of equivalence; follow-up lasted only 16 weeks (paper: https://doi.org/10.3389/fnut.2026.1815820). My take: judge a nutrition tool by the sustainable habits it supports, not the technology alone.
