I was surfing and reading some web articles last night, and one of them was this article in the British newspaper The Independent.
To keep slim and trim, it recommends starting meals with soup.
. . . eating soup, particularly the broth-based vegetable kind, before your entrée fills you up so you eat less during the meal . . . A two-year French study of 2,188 men and 2,849 women found that those who ate soup five to six times a week were more likely to have BMIs [Body Mass Index] below 23 (considered lean), compared with infrequent or non-eaters whose BMIs tended to be in the 27 range.
Obviously, they were not eating cream-based soups.
