                                While the idea of physically shrinking your stomach by eating less is a common myth, the truth is that your body's hormonal and neurological signals are what adjust to smaller portions. Consistent, smaller meals train your body to register feelings of fullness with less food, a process that relies on shifting your appetite signals.
