The liver is the body’s second largest organ and plays a vital role in detoxification and nutrient metabolism. When excess fat builds up in the liver, it can lead to a condition known as fatty liver disease, or hepatic steatosis.

If left unaddressed, this can progress to more severe conditions like fibrosis or cirrhosis. Fortunately, fatty liver disease is often reversible when contributing factors are managed.

While alcohol is a well-known cause of liver damage, it’s not the only one. Nonalcoholic fatty liver disease (NAFLD) and its more severe form, nonalcoholic steatohepatitis (NASH), are now among the most common chronic liver conditions. According to the NIH, NAFLD is closely linked with obesity, type 2 diabetes, and other metabolic disorders.

Research has identified sugary drinks as major contributors to liver fat accumulation—comparable to alcohol. Fruit juices, sweetened teas, energy drinks, and sports drinks all contain high levels of sugar, especially fructose, which the liver converts to fat. Unlike whole fruits, juices lack fiber, causing rapid sugar absorption. Energy and sports drinks, packed with sugar and stimulants, can increase liver enzymes and fat buildup. Reducing intake of these beverages can help prevent or even reverse liver damage.
