Scientists says if you want to lose weight, drink soup instead of eating solid food. According to them, drinking soup instead of eating solid food makes you feel full and keep the hunger pangs longer.
Here is the theory confirmed by scientific study. When you eat a meal consisting of solid food plus water eaten separately, the pyloric sphincter valve at the bottom of the stomach closes to hold the food. Water however will pass through the sphincter valve to pass on to the intestine. Thus even though you drink water, the water do not contribute to you feeling full. However, if you put the solid food and water into the blender to blend it thus making soup, when you drink the soup and the mixture goes into the stomach, the mixture remains in the stomach thus contributing to the full feeling for longer and postpone the hunger pangs. Thus you will eat less and thus will lose weight.
