No, over-eating is not the only reason to obesity, genetic effects in your lifestyle play a huge role too!

Stockholm, 7 September: We have most of times encountered people blaming their genes when they see their own body defects. That’s not true! Genetic effects in our body depend on our lifestyle. The risk for developing obesity is influenced by our lifestyle as well as our genes. In a new study from Uppsala University in Sweden, researchers show that our genetic risk for obesity is not static, but is influenced by our lifestyle. 

 
 
In the current study, researchers have investigated if genetic effects are influenced by different lifestyle factors such as diet, smoking, socio-economic status, alcohol consumption and physical activity. The study builds on genetic and self-reported lifestyle information from 360,000 middle-aged people in the UK.
"The results of our study clearly show that the environment and the lifestyle interact with the genes," says Mathias Rask-Andersen, researcher at the Department of Immunology, Genetics and Pathology, who led the study.
For example, the effect of genetic factors was lower in the most physically active participants. The genetic risk for obesity was more pronounced in participants with lower socio-economic status than in participants with higher socio-economic status. One of the most surprising results of the study was that alcohol consumption also influenced the genetic effects. The researchers could clearly see that the genetic effects were lower among those with more frequent alcohol intake. The genetic effect was nearly half as strong in participants who consume alcohol every day compared with never-drinkers.
The results are a crystal-clear proof that we can indeed influence our own genetic risk by changing our lifestyle. The hope is only that the results of this study will lead to new angles of approach to understanding the mechanisms that regulate body weight and to better methods of treating and preventing obesity and overweight.
