When teenage boys with fatty liver disease were given all their meals and told to avoid added sugars and juice for 8 weeks, they cut their sugar intake by nearly 8% of total calories more than those eating normally, and most stayed on track.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether intensive dietary support strategies (e.g., meal provision) consistently enable adolescents with NAFLD to achieve and sustain free sugar intake below 3% of calories across diverse socioeconomic settings.
A systematic review and meta-analysis of all RCTs and cohort studies in children with NAFLD that report free sugar intake before and after intensive dietary interventions involving meal provision, with subgroup analysis by income level, ethnicity, and duration of follow-up.
Whether meal provision is necessary to achieve and maintain <3% free sugar intake in adolescents with NAFLD, compared to nutritional counseling alone.
A multicenter RCT of 120 adolescents with NAFLD randomized to either meal provision with <3% free sugar or intensive nutritional counseling with no food provision, measuring free sugar intake via 3-day dietary records at 8, 24, and 52 weeks.
Whether adolescents who achieve <3% free sugar intake through counseling (without meal provision) maintain lower liver fat and ALT levels over 2 years compared to those who do not.
A prospective cohort study of 300 adolescents with NAFLD receiving standardized nutritional counseling, tracking free sugar intake quarterly and liver fat via MRI-PDFF annually for 2 years, stratifying by whether they achieved <3% sugar intake.
Whether adolescents with NAFLD who fail to reduce sugar intake below 5% despite counseling have worse liver outcomes than those who succeed.
A case-control study comparing 60 adolescents with NAFLD who failed to reduce sugar intake below 5% after 6 months of counseling to 60 who succeeded, matched for baseline BMI and liver fat, with liver biopsy and metabolic markers as outcomes.
Whether current free sugar intake below 3% is associated with lower liver fat in adolescents with NAFLD who are not receiving meal provision.
A cross-sectional analysis of 500 adolescents with NAFLD not receiving meal provision, measuring free sugar intake via 3-day dietary records and liver fat via MRI-PDFF, adjusting for income, education, and food access.
