Abstaining from alcohol for just one month has benefits for liver, blood sugar and cholesterol health, according to researchers at the New Scientist, a British health and science publication.

For five weeks, 10 staff members at the New Scientist steered completely clear of alcohol, while four others continued drinking as they normally would. Participants took health surveys, liver ultrasounds and gave blood before and after the month-long study.

By the end of the trial, liver fat readings in the “Dry January” non-drinking group fell an average of 15 percent. They also reduced their glucose readings by an average of 16 percent. The dry group also experienced improved blood cholesterol, sleep and weight loss results.

The findings show the extent of damage that even casual drinking can have on the liver and overall health. Fat in the liver can be a precursor to liver damage, fibrosis, cirrhosis and hepatitis.
