This article is interesting it suggests that eating soup can help you lose weight. Apparently if you were to eat a meal of chicken of vegetables with a glass of water you would only feel full for a couple of hours but if you have the same meal blending the water with the food to make soup it fills you up for much longer. According to the article this is down to the fact that after you have eaten a meal the pyloric sphincter in your stomach holds back food so that digestive juices can work. Water passed through the sphincter to your intestines and therefore does not fill you up. However, when the water is mixed with food the mixture stays in the stomach making you feel fuller for longer. I quite like soup but I also like bread to dip in it which I think adds any extra calories that you might save by not snacking.
