Teenage boys with fatty liver disease who followed a very low-sugar diet for eight weeks saw their heart health scores improve significantly, while those who ate normally did not show any clear change.

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 consistent within-group improvements in CVH occur across multiple studies when free sugar is restricted to <3% in adolescents with MASLD, independent of between-group comparisons.
A systematic review and meta-analysis of all published RCTs and controlled trials reporting within-group changes in Life’s Essential 8 scores following free-sugar restriction (<3% of calories) in adolescents with MASLD, using standardized outcome reporting and adjusting for baseline CVH, duration, and dietary adherence.
Whether a low-sugar diet causes a within-group improvement in CVH scores in adolescent boys with MASLD, when compared to baseline under controlled conditions.
A single-arm RCT with 50 adolescent boys with MASLD receiving a study-provided diet with <3% free sugar for 8 weeks, with CVH scores measured at baseline and endpoint using Life’s Essential 8, and adherence monitored via food logs and biomarkers, with no control group.
Whether adolescents with MASLD who naturally reduce free-sugar intake over 8 weeks show similar CVH improvements as those in controlled dietary interventions.
A prospective cohort of 100 adolescent boys with MASLD tracked over 8 weeks, measuring daily free-sugar intake via food diaries and CVH scores at baseline and endpoint, with analysis of whether those reducing sugar by >50% show greater CVH improvement than those maintaining intake.
Whether adolescents with MASLD who report large reductions in sugar intake over the past 8 weeks have higher CVH scores than those who did not change intake.
A case-control study comparing 50 adolescents with MASLD who reduced free-sugar intake by >50% over 8 weeks (cases) to 50 who maintained intake (controls), matching for age and baseline CVH, and assessing sugar intake via retrospective food frequency questionnaire.
Whether current free-sugar intake levels correlate with current CVH scores in adolescents with MASLD at a single time point.
A cross-sectional survey of 200 adolescents with MASLD measuring current free-sugar intake via 3-day food records and CVH score via Life’s Essential 8 on the same day, with analysis of correlation coefficients.
