A study published in the journal Cell Metabolism by researchers from the University of Pennsylvania found that eating too much at each meal affects liver health. 

The researchers, using mice as subjects, conducted a study on the relationship between diet and liver health.In the experiment, two key molecules affecting liver health were identified.One molecule is responsible for storing fat, while another promotes fat combustion to generate energy.The research found that these two molecules can maintain healthy fat levels when they complement each other;When removed from the liver, these molecules result in a rapid accumulation of toxic fats within the liver, leading to the formation of fatty liver.Researchers discovered that eating too much at each meal, exceeding our energy needs for each meal, causes food fats to be absorbed by the liver, increasing the burden on both types of molecules and preventing normal energy storage and consumption. Over time, this leads to a balance between energy storage and expenditure, causing inflammation and liver damage, ultimately leading to death. 

Dr. Lazarus stated that this research proves that overeating not only causes obesity but also increases the risk of developing liver disease.The study also provides new directions for treating liver injury caused by binge eating.
