Obesity and Genetics

Obesity and Genetics

Scientists have shown that genetics plays a huge role in obesity. If you look at two obese parents, you will find that their offspring are much more likely to be obese. You might conclude environmental factors such as poor eating habits and exercise habits were causes of the obesity problem. However, on closer inspection, you find that there is a real genetic component that is quite powerful.

Twin Studies

Twins that have been separated at birth and raised in different families will most often be less than 10% different, in weight, than their twin. If genetics didn't play a large role, you would expect to find large variations in body composition and scientists just aren't finding this evidence.

Adoption Studies

Adopted children much more closely resemble their biological parents in body composition than their adopted parents. This factor, alone, shows that the biological component is more powerful than the genetic component.

Gene Discoveries

Many genes have been discovered to be part of the makeup of an obese individual. The idea is that some of our ancestors went through periods of feast and famine. Some of us are genetically programmed to be thrifty and save onto the food energy (fat). This makes the species stronger and more capable of survival. However, in today's society, the abundance of calorie dense foods makes people with thrifty genes become obese.

Obesity Risk and Genetics

You may not have superior genes, but that doesn't mean you were meant to be obese for a lifetime. If you have obesity genes, it only means that you are at a higher risk for the disease. In this case, you should live in a more pragmatical and systematic way. Through diet and exercise even those at high risk can control their weight over 98% of the time.
