Hunger and satiety

The body can give us a variety of signals through hormones which regulate satiety and hunger. Some have bodies that give clear cues to fullness, whilst others can have trouble recognising when the body has had enough. Some children find it very difficult to tell the difference between what the body needs compared to what it needs. 

Physiological regulation of hunger

 
It takes practice and time for a child to learn how to respond to the signals from the body telling us when it needs food, drink or has had enough to eat. An important part of this is letting the child be in charge of the amount of food on the plate and making independent choices. It is the adult's responsibility to provide food, create a suitable meal time schedule and make the food. The child can then choose what it would like to eat out of what is offered, and the amount of food. Avoid putting pressure on the child in saying that he/she must finish their plate before leaving the table. That often leads to the child ignoring the body's feedback. Respect the child's decision in saying that he/she is content and would like to leave the table, even if there is still food left.
 

Parents/caregivers role in regulating appetite and satiety

Years of clinical experience, as well as a growing body of knowledge, show that children with obesity have trouble in recognising fullness. These children a from a very early age show an appetite level that is higher compared to children who have a lower body weight. They also experience satiety at a slower rate, making it more difficult to adjust food intakes. Parents/caregivers can support a child struggling with appropriate intake of food by using one or more of the following strategies
 

Slowing down

Eating with more leisure and spending time eating are effective ways of letting the child recognise signs of fullness. Chewing more slowly, eating foods that require cutlery and drinking water whilst eating helps the stomach/intestines in sending signals to the brain, where satiety hormones are produced. It takes about 15-20 minutes before we notice fullness. Eating more slowly and spending time at the table e.g talking is a skill that needs practice. Toddlers and pre-schoolers will not have the patience to sit for very long, but this is where healthier foods and appropriate portion sizes become more important in adjusting amounts.

Try using the image of a fuel gauge when talking about feeling hunger and feeling content to a child. The green colour suggests a happy medium where the tummy has had just about the right amount of food, whereas the red areas illustrate how it feels when someone is very hungry on one end of the scale, compared to the other end where the tummy is so full that it can be uncomfortable.
