According to the University of Reading, the compound lycopene, which makes tomatoes red, appears to lessen your appetite, making tomatoes, over other vegetables, the perfect choice for dieters.

According to the Daily Mail, the research looked into the benefits of enriching white bread with fruit and vegetables.  It tested women aged 18 - 35 on cream cheese sandwiches.  The bread in the sandwiches was either standard white bread or bread enriched with carrots or tomatoes, and it was the tomato bread that filled the women up the most.

The Telegraph quotes Dr Julie Lovegrove, a specialist in nutritional metabolism who is leading the project ”It was a small study, and we can’t yet say what the crucial tomato ingredient is, but the results were statistically significant.”
