Fat production and burning are synchronized in livers of mice with obesity

Mice fed a fattening diet develop new liver circadian rhythms that impact the way fat is accumulated and simultaneously burned. The team found that as liver fat production increases, surprisingly, so does the body's ability to burn fat. These opposing physiological processes reach their peak activity each day around 5 p.m., illustrating an unexpected connection between overeating, circadian rhythms, and fat accumulation in the liver.
