Eating too much sugar, especially fructose found in sodas and sweet snacks, tricks your liver into making excess fat, which can lead to a fatty liver, make your body less responsive to insulin, and raise your risk of heart disease.

Assessment Explanation
The claim describes a multi-step causal pathway supported by mechanistic, observational, and short-term intervention studies in humans. However, while fructose overconsumption is strongly linked to hepatic lipogenesis and NAFLD in controlled trials, direct causal proof linking it to coronary artery disease in humans via insulin resistance remains inferential due to confounding factors (e.g., overall calorie excess, sucrose vs. fructose sources). The verb 'promotes' and 'contributing to' are appropriately cautious, but 'leads to' could imply inevitability. The claim is not overstated but would benefit from probabilistic language to reflect population-level risk rather than deterministic outcomes.
More Accurate Statement
“Chronic overconsumption of dietary fructose is associated with increased hepatic de novo lipogenesis, which likely contributes to the development of non-alcoholic fatty liver disease and may increase the risk of systemic insulin resistance and coronary artery disease.”

Evidence from Studies

Dietary fructose feeds hepatic lipogenesis via microbiota-derived acetate
When people eat too much fructose (like in soda), their gut bacteria make a chemical that the liver uses to create fat, and the liver itself also gets a signal to make more fat — leading to fatty liver and related health problems like insulin resistance and heart disease.
Role of Dietary Fructose and Hepatic De Novo Lipogenesis in Fatty Liver Disease
Eating too much fructose (like in sugary drinks) makes your liver produce more fat than it should, which can lead to fatty liver, insulin resistance, and eventually heart disease — and this study shows exactly how that happens.
