Can eating less or fasting cause a reduction of the volume of the stomach? Many like to believe so. But is it true?
The stomach is a muscle. It stretches when it fills. Our stomach has the ability to expand up to a certain limit.
Approximately 4 hours after a meal, the stomach is empty of its contents. It then has its initial volume, which is about 50 ml, regardless of the quantity of food or liquid ingested. Therefore, the stomach does not shrink after digestion and does not shrink further if you fast or eat less.
