Low-GI Breakfast Reduces Children's Appetite For The Rest Of The Day

Not really.
"A new long term study, led by Professor Henry at Oxford Brookes University, UK, has shown that children eat approximately 60 kcal less during the day following a low-GI breakfast, than after a high-GI breakfast..."
"Long-term" was "two non-consecutive weekdays over 10 weeks."

The lie: "Low-GI Breakfast Reduces Children's Appetite For The Rest Of The Day"

The truth: "...
this difference could have happened by chance..."

Interesting study design in that it cannot distinguish between chance and cause and effect.

Also seems not to have addressed Calories burned following the different meals. So, for example, if a high-GI meal caused these kids to run around more and burn off 100 more Calories, then the high-GI diet resulted in a net 40 Calorie decrease per day.

Either way, studies whose results "could have happened by chance" are useless.

As is using the GI as the approach to overweight/obesity.

It is all about Calories in vs. Calories out. How you get there makes no difference.

More Einsteins at work.
