Eating fructose (like in sugary drinks) makes your body store more fat around your organs and liver than eating the same amount of glucose, even if you’re not eating too many calories overall.
See the scientific wording
Fructose consumption, when compared to glucose consumption, promotes greater deposition of visceral and hepatic fat in humans, even under conditions of energy balance.
Correlational — new studies may shift this
One low-scoring study links this claim to the outcome, but causation is not established.

Fructose drives de novo lipogenesis affecting metabolic health
Narrative ReviewReview2023
This study shows that when people eat fructose (like in sugary drinks), their liver makes more fat than when they eat glucose (like in bread), even if they’re not eating too many calories overall — which means fructose is more likely to cause fat buildup in the liver.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.

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.
Systematic Review and Meta-Analysis of Isocaloric Fructose vs. Glucose Feeding Trials on Visceral and Hepatic Fat in Humans
Includes only randomized, isocaloric, controlled feeding studies in humans with direct measurement of visceral and hepatic fat via MRI or CT, comparing fructose to glucose over ≥2 weeks.
Double-Blind, Isocaloric, Crossover Trial of Fructose vs. Glucose on Hepatic Fat Accumulation in Healthy Adults
Healthy adult participants receive 2–4 weeks of isocaloric fructose or glucose supplementation in random order, with hepatic and visceral fat measured by MRI before and after each phase.
Prospective Cohort Study of Dietary Fructose Intake and Long-Term Changes in Visceral and Hepatic Fat in Free-Living Adults
Follows a large cohort of adults over 3–5 years, using dietary records and periodic imaging to correlate fructose intake with changes in visceral and hepatic fat, adjusting for total energy intake.
Case-Control Study of High Fructose Consumers vs. Low Fructose Consumers with Elevated Hepatic Fat
Recruits individuals with confirmed high hepatic fat (via imaging) and matched controls without, then retrospectively assesses their dietary fructose and glucose intake over the past year.
Cross-Sectional Analysis of Fructose Intake and Liver Fat in a Population-Based Sample
Measures dietary fructose and glucose intake via food frequency questionnaire and liver fat via ultrasound in a large, representative adult population sample.
