Eating a lot of fructose (like in sugary drinks) might turn up the activity of certain liver enzymes that process sugar and make fat, especially in people who already have metabolic problems like obesity or diabetes.

Eating too much fructose—like the sugar in soda and candy—can slow down your liver’s ability to burn fat, making fat build up and mess up your metabolism.

Eating too much fructose, like the sugar in soda and candy, can mess up your liver’s ability to respond to insulin, make more fat in your liver, and raise fat levels in your blood, which can lead to bigger health problems like heart disease.

When people eat a lot of fructose (like in sugary drinks), their liver has a harder time burning fat for energy, especially if they're also eating a lot of fat — which can lead to fat building up in the liver.

Eating too much fructose, like the sugar in soda and sweet snacks, makes your liver create more fat, which raises bad fats in your blood and causes body-wide inflammation, making heart disease more likely.

If you eat less fructose—like the sugar in soda and candy—your liver will make less fat, even if you don’t eat fewer calories overall. This can help reduce fat buildup in the liver, especially if you’re overweight or have fatty liver disease.
