And two different studies just this past week added more data to back that up.

So quickly, the first one out of France, published in Cell Reports, they tracked down a mitochondrial enzyme called ACSF3 that appears to be a direct link between feeding time and how your liver, double-click on liver, organizes its metabolism across the day.

They found that meal timing switches on a nutrient signaling pathway that drives the daily rhythm of hundreds of genes in your liver, and here's the kicker, independently of your body's master clock.
