You don’t have to lose weight to clean fat out of your liver—just eating less sugar, more protein, or taking fish oil can help, even if the scale doesn’t budge.

Assessment Explanation
The claim describes a causal effect of specific dietary patterns on liver fat independent of weight loss, which is testable in controlled human trials. However, the use of 'can achieve' implies a generalizable, reliable outcome, while existing evidence shows variability in response. The claim is not overstated because it does not claim universal success, but it should reflect probabilistic outcomes based on current data. Most studies show moderate effect sizes with heterogeneity, so 'may achieve' or 'has been shown to reduce' is more precise.
More Accurate Statement
“Eucaloric dietary interventions that restrict carbohydrates, increase protein intake, or supplement with omega-3 fatty acids may achieve clinically meaningful reductions in intrahepatic fat in individuals with NAFLD without requiring changes in body weight or BMI.”

Beyond Body Weight-Loss: Dietary Strategies Targeting Intrahepatic Fat in NAFLD
This study found that you can reduce liver fat by changing what you eat—like eating fewer carbs and more protein—even if you don’t lose any weight. That supports the claim that losing weight isn’t necessary to fix fatty liver.
