Half of parents with an overweight or obese child think their kids are slimmer than they actually are, according to a new review of past studies. Recent studies show children who are over weight as a child will most likely remain obese in later life. Parents play a very crucial role in preventing childhood obesity, and interventions are most successful if they involve parents. If the parents do not recognise their child is overweight or are not concerned, they are not going to take steps to address it. An insightful parent is paramount to the successful management of childhood obesity.
