Measurement of fuel stores in children on waking and after breakfast

10 March 2020

Glycogen is the main storage form of carbohydrate in the body, and it is assumed that on waking children need to replenish these stores, which are depleted while sleeping, to start the day and perform well in physical and mental activities. However, we don't know how low these stores are in children in the morning and how quickly they can replenish them after eating. We will use a MRI scanner to assess muscle and liver glycogen content before and after sleeping, and after breakfast.
