The reasons of a child developing childhood obesity are numerous. This report will explain the consideration of a child's genes being responsible for "inheriting" the condition of childhood obesity.

Former research efforts have suggested that adult body-mass index (BMI) is 55 percent to 85 percent heritable. Genes in the region of 15q11?13 could be abnormally suggestive as the end result of possibly a structural or functional abnormality in this chromosomal region. At this date the exact genetic culprits have not yet been identified, the
genetic lesion(s) seem to relate to hypothalamic dysfunction.

Nevertheless, observations of the explosion of the visually obvious prevalence of childhood obesity in developed nations obviously indicates genetics should not blamed as a significant cause for the current jump that has been seen in recent decades. Genetic syndromes where obesity is considered a key event are very rare. In addition these usually have an linked major physical abnormality as well as mental retardation.

Dysmorphic syndromes, known as Turner's and Beckwith-Wiedemann, are normally specified in early childhood.

Numerous research studies suggest that genetics can feasibly assist to explain a child's preference for selective food cravings, such as sweet foods as diametricallyopposed foods possessing a savoury or salty flavour. A child with a genetic preference to sweet flavoured foods may attract a child genetically disposed to have a desire for
innappropriate servingsd of sweet foods such as icecream, and in particularly, heavily sugar saturated bottled drinks.

Future research into the affect of genes on childhood obesity could assist to understand the reasons why a child fixates on fast food outlet bought ham-burgers,fish and chips, and other fast foods, in preference to home-cooked meals .

On the one hand this problem may simply be due to the reluctance of the modern parent to devote time and effort in preparing a healthy home cooked meal, in preference to giving in to a child's desire for food from a fast food outlet due to the fact that most parent's are in the workforce?
