2005 Study at Purdue University, Lafayette, USA

Solid and liquefied versions of identical foods high in protein, fat or carbohydrate (containing the same number of calories) were given to 13 male and 18 female volunteers. Beverages were also tested. The participants completed questionnaires on mood, appetite and psychological state. Eating soup led to reduced hunger. Overall calorie consumption tended to be lower on days when soup was eaten compared with days on solid foods and beverages. Beverages had the least effect on hunger reduction. The researchers concluded that soup may help to reduce appetite.

2003 Study at the New York Obesity Research Center, St. Luke’s-Roosevelt Hospital Center, New York, USA

Cholecystokinin (CCK) is a gut hormone that plays a role in satiety (feeling full). Levels of CCK rise after a meal, and this helps us to feel full. The researchers wanted to test whether soup quenches appetite by stimulating higher levels of CCK. They measured plasma CCK levels in eight healthy, non-obese men and women before and after eating 800 grams of tomato soup, followed 30 minutes later by 300 grams of a yoghurt shake. Appetite ratings were compared with CCK levels. It was found that eating soup significantly increased plasma CCK levels within 30 minutes in all subjects combined. Interestingly, the women’s average CCK levels were significantly higher than the men’s. The researchers concluded that eating soup may be especially beneficial for women who want to lose weight.
