Why should a family-based approach be used to support a child's healthy weight?

Children eat what the family buys and copy their parents' habits. Changes made by the whole family avoid singling out the child and are more likely to last.

Justify limiting children's screen time as part of achieving a healthy weight.

Less screen time frees time for active play and reduces exposure to food adverts. Children also snack less when they are not eating in front of screens.

Justify the aim that children aged 5 to 18 are active for an average of at least 60 minutes a day.

Daily activity raises energy expenditure and builds muscle, which raises BMR. Active children are more likely to stay active as adults.

Justify serving age-appropriate portions and regular meals to children.

Child-sized portions on smaller plates match intake to a child's lower energy needs. Regular meals, including breakfast, reduce grazing on energy-dense snacks.

Questions from this subtopic

Each one with the model answer underneath.

1
Why is weight loss not usually the aim for a growing child above a healthy weight?
Model answer
Children are still growing in height, so keeping weight steady lets them grow into it. Strict dieting in childhood can limit the nutrients needed for growth.
2
Propose and justify one change to drinks for a child above a healthy weight.
Model answer
Sugary drinks should be replaced with water or lower-fat milk. Sugary drinks add energy without fullness, so removing them cuts intake without leaving the child hungry.
3
Why should a family-based approach be used to support a child's healthy weight?
Model answer
Children eat what the family buys and copy their parents' habits. Changes made by the whole family avoid singling out the child and are more likely to last.
4
Justify limiting children's screen time as part of achieving a healthy weight.
Model answer
Less screen time frees time for active play and reduces exposure to food adverts. Children also snack less when they are not eating in front of screens.
5
Justify the aim that children aged 5 to 18 are active for an average of at least 60 minutes a day.
Model answer
