There are many studies that demonstrate a strong association between eating breakfast and maintaining a healthy weight. You don’t “save” calories by not eating until lunch time, all you do is back-load your intake to late in the day and make poor food choices because you’ve starving. Realize that your body has already been fasting while you were sleeping and it needs fuel to get going in the morning, whether you feel hungry or not. A steady stream of healthy food signals your body to burn calories rather than store them.
