Skipping breakfast regimen induces an increase in body weight and a decrease in muscle weight with a shifted circadian rhythm in peripheral tissues of mice

Skipping breakfast over two weeks led to increased body weight gain and changes in metabolism in mice.

• Mice that skipped breakfast showed a notable increase in body weight and fat around the kidneys.
• The weight of muscle in the feet decreased in mice that skipped breakfast compared to those that did not.
• Circadian rhythms in gene expression related to metabolism were disrupted in the liver, fat, and muscle of the breakfast-skipping group.
• The findings may indicate a link between skipping breakfast and risks for obesity, metabolic disorders, and muscle loss.
