A child that suffers from overweight or obesity is one that should regarded as having a temporary disease, the obesity condition is dangerous for the child heath and has effect on his social life, self esteem and confidence.
When you decide that you want to fight, and beat childhood obesity you should think carefully or a plan and a tactic you will use to fight this condition.
The three major keys in losing weight and having a successful diet plan are regular physical activity, performed on a set schedule and without exception the physical activity will encourage the child to get better and hopefully cause him or her to focus on activity rather than on food or the discomforts of the diet.
The next key to fighting childhood obesity is naturally a diet, making a diet plan should be done after advising with a diet professional that has all the tools and information about your child and his or her needs. making a realistic plan that will take a long time to complete you will gradually adapt new eating habits, showing the child that there are different kinds of foods and that making the child conscience of the things they eat and their effect on weight and the body. Increasing the awareness to the effect of different foods is a very important thing since it clearly identifies the cause and effect relationship to the child.
The last key for beating childhood obesity is as important and as natural as the first two, it is slowly and gradually changing the behavior of the child, and sometimes of the whole family, the new behavior patterns can be treated as rules first, make sure you explain why it is not good to eat candies, and more impotently you should make sure that your child knows that from time to time he or she are allowed to make an exception and have a candy, do not delete and block sweets from their lives completely since this usually has the opposite effect on kids.
The behavior change is a major one and if effects all the rest of the keys mentioned here, you should try and set rules in the beginning, if you can have a family meeting and set those rules it will be beneficial for everyone, making the children feel that they are setting these rules, you should encourage your kids to set rules and live by them, when you first start you can also join their activities to show them they are not alone, and from time to time you could explain how important it is to follow the rules and the benefits that are waiting in the end of the road.
A technique I have heard about some time ago uses imagination and positive thinking to encourage obese children to maintain a diet and physical activity routine. The parents have a weekly talk with the child and they go over all the last week events, good and bad, trying to explain what happened and why, not forgetting to compliment the child on his or her achievements.
Once the events have been reviewed and points made clear the parent and the child close their eyes and imagine how it would be like in a month or two ahead, with more weight loss and better fitness and daily routine, talk about all the benefits of losing weight, like nicer clothes, better feeling, more energy, social admiration and so on, just make sure that the goals are realistic and can be achieved in a month or two of hard work, when your child achieves this you should mention the talk to him or her and demonstrate how belief and will power has real effect on life.
