Childhood obesity is an increasing health problem that is being faced globally and also in Malaysia. Obesity may lead to many diseases such as heart attack and diabetes. Obese children are prone to stay obese after growing up. So, it is important to reduce obesity right from childhood. Persuasive technology can be used to motivate people to change their behavior. There are two approaches of persuasive technology that can be used in childhood obesity intervention.
