If you think skipping your morning tea and toast will help you shed a few pounds, you could be mistaken.
Researchers claim people who miss breakfast not only eat more for lunch but also crave fatty and sugary foods, putting them at risk of gaining rather than losing weight.
Scientists at Imperial College London scanned the brains of 21 volunteers while they looked at pictures of different foods, such as salads and chocolate.
They also had to rate the foods' appeal. The volunteers were then given an all-you-can-eat pasta lunch. Those who had missed breakfast ate around 250 calories more - the equivalent of a chocolate bar.
They also found high-calorie foods more tempting, the Society for Neuroscience's conference heard.
