Childhood obesity is a serious medical condition that affects children and adolescents. It occurs when a child is well above the normal weight for his or her age and height. Childhood obesity is particularly troubling because the extra pounds often start children on the path to health problems that were once confined to adults, such as diabetes, high blood pressure and high cholesterol. Childhood obesity can also lead to poor self-esteem and depression.
One of the best strategies to reduce childhood obesity is to improve the diet and exercise habits of your entire family. Treating and preventing childhood obesity helps protect the health of your child now and in the future.

Parents play a crucial role in helping children who are obese feel loved and in control of their weight. Take advantage of every opportunity to build your child's self-esteem. Don't be afraid to bring up the topic of health and fitness, but do be sensitive that a child may view your concern as an insult. Talk to your kids directly, openly and without being critical or judgmental.

Lifestyle Remedies
Healthy eating
Parents are the ones who buy the food, cook the food and decide where the food is eaten. Even small changes can make a big difference in your child's health.
Physical activity
A critical part of weight loss, especially for children, is physical activity. It not only burns calories but also builds strong bones and muscles and helps children sleep well at night and stay alert during the day. Such habits established in childhood help adolescents maintain healthy weight despite the hormonal changes, rapid growth and social influences that often lead to overeating. And active children are more likely to become fit adults.
