The prevalence of overweight children is increasing every year. In England, in the year 2019/2020, the prevalence of overweight increased rapidly. The National Child Measurement Program measure shows that in Reception (4-5 years old), the obesity rate was 9.9% and continued to increase to 21% in year 6. Childhood obesity is tackled early so complications can be managed before it worsens. There are many ways to prevent childhood obesity.


The National Institute for Health and Care Excellence guidance currently recommends lifestyle intervention as the main treatment for prevention of childhood obesity. Diet management and physical activity are the main areas to focus on for obesity prevention. Dietary modification includes limited use of refined grains and sweets, potatoes, red meat, processed meat, sugary drinks, and alternatively increase intake of fresh fruits and vegetables, whole grain and adopt more healthier food options, instead of fatty and junk food. On top of that, add physical activity in daily routine. It is one of the key factors for reduction of obesity. Another way for communities to tackle obesity is to take part in government programmes such as Healthier You and NHS Digital weight management programme, which are helpful for handling obesity.
