There is this study that suggests
Cold Breakfast Cereal Better for Kids Than a Hot Breakfast
A study [using data from the National Health and Nutrition Examination Survey 1999-2006] shows that kids who eat cold,
ready-to-eat cereal in the morning
have a lower risk of obesity than
those who eat a hot breakfast.
[...]
Researchers studied the breakfast
eating habits of almost 10,000
children between the ages of 9 and
18 to see how what they ate in
the morning affected their total
nutritional intake for the day - and
their risk for obesity.
They looked at kids who ate standard
breakfast cereals, those who skipped
breakfast, as well as kids who ate a
non-cereal breakfast - such as a hot
breakfast.
[...]
The kids who skipped breakfast
completely were the most likely to be
obese - but the cereal eaters had a
lower risk of being overweight or
obese than the kids who ate a hot
breakfast or any other type of
breakfast.
The research was funded by the US Department of Agriculture and Kellogg's Corporate Citizenship Fund.
