WHAT SHOULD BE THE PORTION SIZE OF MEALS, SOUPS AND SALADS?

We all have different bodies and it is difficult to predict one portion size that would suit everyone. However, we should eat only till we're 1/2 full. If you fill a blender till the top, would it be able to blend? No, because it needs some empty space to twist and turn the ingredients inside. Similarly, if you fill your stomach till the top, will it be able to break down and digest your food? No, because it needs empty space to release and mix digestive juices with the food, and allow for the expansion and contraction of the stomach. Even wholesome food, if eaten in excess, becomes toxic filth.                        

We get a burp (called the burp of contentment) while eating, that's when one should stop eating.
