Do all people have the same size stomachs?

Answer 1

Thin people are less likely to eat until they are physically full, just until they are not hungry anymore. As a result their stomach are more sensitive to stretching, which is what causes that uncomfortable full feeling. People who gladly eat to fullness at every meal will become less sensitive to this stretching sensation, and they can physically stretch their stomachs if they continue this practice. In fact the reason weight loss surgery sometimes fails is because people will manage to eat enough to stretch that tiny pouch of stomach that they still have available until its more like the size of a normal stomach.

Restoring the "tightness" of your stomach requires that you never eat until you are full.

Answer 2

The stomach can stretch to accommodate a large amount of food. So, for example, in very overweight people who do eat a lot, the stomach often does not feel full and it does have room for more food.

Conversely, the stomach can also "shrink" when a person has not been eating normally. Many ill people and elderly who are not eating much experience fullness and discomfort with less than a child's sized serving.

The ideal eating habit is to stop eating beforeyou feel full. The brain takes approximately 20 minutes to register "fullness" or appeasement of hunger. So if you stop eating before completely "full", the brain will finally register the meal, report back the sensation of "fullness", and the stomach will not feel stretched and bloated. Overweight people who eat a lot of food often lose that feedback from the brain; the person never feels full.

Note: Not all overweight people eat too much food. There are many conditions that contribute to weight gain and obesity, not just over-eating.
