India"
A study conducted in 2012 “(Common variants of FTO are associated with childhood obesity in a cross-sectional study of 3,126 urban Indian children.)” States the association of FTO variants with obesity, this study was performed on 3,126 Indian children (aged 11-17 years) including 2,230 normal-weight and 896 over-weight/obese children. This study indicates that the FTO gene factor is more prominent to affect children rather than adults.
There is a
lot of research being done on obesity and its causes, however we normally look upon
factors such as excess energy intake, reduced physical activity or lifestyles,
there is another factor emerging as a major component in the rise of obesity.
Genetics, Genetic variants play a key role in one’s body weight. It has emerged that there are particular
variants associated to obesity and overweight. One such gene is FTO, also known as alpha-ketoglutarate-dependent dioxygenase FTO is an enzyme that in humans is encoded by the FTO gene located on chromosome 16.
People have two copies of the FTO gene - one from each parent - and each
copy comes in a high and a low-risk form. Those with two-high risk copies of
the FTO gene are thought to be 70% more likely to become obese than those with
low-risk genes. This mechanism
works by affecting the ghrelin hormone.
Another hormone AMD1 is a genetic variant associated with childhood
obesity.
A study conducted in 2012 (Genetic variant of AMD1 is associated with obesity in urban Indian children.) this study indicates that there is an association of AMD1 (adenosylmethionine decarboxylase 1) variant with obesity and plasma leptin levels in children.

This is the precise weblog for anybody who needs to seek out out about this topic. You notice so much its almost arduous to argue with you. You positively put a brand new spin on a subject that's been written about for years. Nice stuff, simply nice!
