According to this article tomatoes could help you lose weight because they make you feel full. Apparently the fruit suppresses the urge to snack and makes you feel full longer. The findings came after researchers looked at the benefits of enriching white bread with fruit and vegetables. A group of people were offered cream cheese sandwiches on white bread with added carrots or tomatoes, with the tomatoes found to be more satisfying. It is thought lycopene, the pigment that gives tomatoes its colour also helps to dull appetite. This seems interesting but unfortunately I hate tomatoes.
