More research on gut bacteria, or microbiome, continues to connect the dots in how our bodies react to what we eat. The latest research compares the western diet, otherwise known as a high fat diet, to a normal one and the impact it has on circadian rhythm.

Researchers at the University of Chicago Medical Center say that WHEN we eat can have a huge influence on clock genes in the liver. Mice who ate a western diet had circadian rhythms that were disturbed at the molecular level, compared to mice who were germ free.

In the intestine, bacteria work in a cycle that helps the clock genes work correctly. In circadian rhythm or sleep-wake cycles, there are also different types of bacteria depending on the time of day. High fat diets alter bacterial signals and the researchers think this could promote obesity.
