Synch Mealtimes With the Circadian Clock, Suggests New Mouse Study

A new study in mice has found that restricting eating to the active period of the daily circadian rhythm limits weight gain and improves metabolic health using increased heat-generating creatine metabolism in fat cells.

Diet and the Gut Microbiome: What Do We Know?

Changes in our microbiome have been linked to fluctuations in our health. The field of gut microbiome research has therefore gathered a lot of interest, as these microbes and their metabolites can influence the rest of the body in health and disease. But what have we learned from recent research?
