Nibble Stretch the face muscle by eating something every two hours. “Nibblers” statistically weigh less than “Gorgers.”2 453. Eat a Fistful Your stomach is the same size as one to two of your fists. As a result, a general rule for controlling how much you eat is that no portion of any one thing should be larger than one fist. 454.
