The role of portion sizes in childhood obesity

Could insisting that kids “clean their plate” be contributing to the obesity crisis?

According to experts, large portion sizes and parental pressure to finish meals may be leading children to overeat, setting the stage for unhealthy weight gain later in life.

A recent poll conducted by the British Nutrition Foundation (BNF) highlights the issue. It found that 37 per cent of parents frequently or always require their children to finish everything on their plate, with another 23 per cent doing so occasionally. Additionally, nearly half of parents reported that their children have second helpings at least once a week.

The poll also revealed that many parents struggle with portion control. While 63 per cent of parents feel confident about serving the right amount of food, 32 per cent admitted they rarely or only sometimes feel sure. Alarmingly, 7 per cent of parents with children aged four and under, and 11 per cent with children aged five to 11, serve their kids the same portion sizes as adults.

Nutritionists warn that serving large portions encourages both adults and children to eat more, which can contribute to excess weight. Bridget Benelam, a nutrition communications manager at the BNF, pointed out that around a fifth of 10- to 11-year-olds in England are living with obesity. “Getting portion sizes right is a crucial part of maintaining a balanced diet that supports a healthy body weight,” she explained.

So, how can parents ensure they’re serving appropriate portions? Benelam suggests using simple, visual cues: “Compare portion sizes to your child’s hand. For instance, a baked potato should be about the size of their fist.” She also advises starting with smaller portions and offering seconds only if the child is still hungry.

The poll also highlighted snacking and dessert habits, with 88 per cent of parents reporting that their children snack between meals at least once a week, and 77 per cent saying their kids enjoy dessert weekly or more.

Ultimately, the findings suggest a need for greater guidance on portion control. Nearly 30 per cent of parents agreed that more information would help them make better decisions about their children’s food intake.

By focusing on portion sizes that reflect a child’s age, body size, and calorie needs, parents can play a key role in promoting healthier eating habits and preventing obesity from an early age.
