What is epigenetic and how it relates to obesity

dietNon-genetic factors that promote weight gain

Today, obesity is a multifactor disease, in which not only genetic influences. Moreover, there are other non-genetic factors that promote weight gain. Therefore, it seems interesting to learn some new terms like what an epigenetic process is and how it relates to obesity.

Because not only genetics and heredity influences obesity or overweight, science has investigated the implications of different epigenetic processes. But to begin to understand a little more these new terms, need to know its definition.

What is epigenetics?

Epigenetics is the study of all non-genetic factors in the development of a disease or condition in this case obesity. Epigenetics is the set of chemical processes that modify the activity of DNA without altering its sequence.


The magnitude of changes varies with each person’s predisposition. Those with more predisposed to being overweight; you are more likely to epigenetic changes.

Now that you know what is interesting to relate the process of weight gain.

How is it related to being overweight?

There are scientific studies supporting that obese and people with other metabolic problems such as diabetes, have different epigenetic marks to the thin and non-diabetics.

These epigenetic changes are due to bad and wrong eating habits and environmental, as well as the lack of healthy habits related to physical activity.

A sedentary lifestyle and high calorie Western diet, high in fat and rich in simple sugars, added stress and other factors, are responsible for the production of genetic changes that lead, in turn, the emergence of other diseases associated with overweight and for example the metabolic syndrome .

In this syndrome are altered several parameters, such as glucose, cholesterol, triglycerides, etc.. The way to reverse this situation and stop epigenetic changes is hindering factors I mentioned earlier.

These changes depend on you. Genetically can be thin, but if you eat improperly and are sedentary, have high chances to change your DNA, which can predispose future generations to overweight.

On the other hand, we must not forget that having a greater chance of suffering from obesity, is not conditioned for life to be, because you can take care of with diet and exercise and you can reverse this situation.

In short, being obese or not largely depends on you. To change this situation, you need decision, perseverance and love yourself.
