As will be discussed more fully in another chapter, the more overweight you are, the more likely you are to stay overweight. 40% of children who are overweight, remain so as adults. Unless something is done, using the right tools, to achieve lasting changes in lifestyle and behaviour, it will be difficult for children to get better by themselves. Statistics show it not to be true, that during puberty the problem of obesity resolves itself spontaneously. Instead, it is a fact that the longer a child remains obese or simply just overweight, the longer and more severe the damage that will be going forward. Finally, it is also a fact that a child who was obese in childhood, but who drops to a normal weight during puberty, has however suffered damage to their body during pre-puberty.
