Obesity And Genetics

From burning fewer calories to the presence of the FTO gene in the body, the expert addressed the issue of obesity and its relationship with the genetic makeup of the body.

Obesity is a health condition which involves the accumulation of a large amount of fat. Unlike what we think, Obesity is not just a cosmetic condition. It, in fact, involves and increases the risk of a lot of other disorders such as heart disease, diabetes, high blood pressure and even certain types of cancers. Obesity is caused by a range of factors – it usually involves eating a lot of calories and not burning enough of them which causes the fat to accumulate. Genetics is also one of the causes of obesity.  Genetics is also one of the causes of obesity.

To gain weight we need to eat more calories than we burn (over time) and to lose weight, we need to eat lesser calories. To control this equation, we can eat more or fewer calories, or we can burn more or fewer calories. We can also do a bit of both.

this formula applies to everyone irrespective of the genetic makeup that they are a part of. “Can our genes make it harder to lose weight? Certain gene variants can make it easier for us to gain weight by making it easier for us to eat more calories than what we burn over time which would lead to weight gain by increasing our drive to eat (hunger and cravings) or reducing the drive to move/burn calories (in simple terms, making us lazier).

FTO gene is a Fat Mass and Obesity Associated Gene which raises the risk of obesity. Referring to the part played by the FTO gene, the expert added, “If you have one copy of the gene (one parent), there would be a difference of 1.5kgs only (on an average). If you have two copies of the gene (both parents), there would be a difference of 3kgs only (on average). So, if we are up to 3kgs up, we can blame our genetics. If it’s more, genetics are not to be blamed.
