Scientists discover two types of obesity

Obesity is a complex disease, often summed up in BMI. Scientists reveal its multiplicity by distinguishing two subtypes of obesity, characterized neither by genes nor by diet.

Obesity is usually diagnosed based on the calculation ofBMIBMI : if it is greater than or equal to 30, the patient is obese. This imperfect tool does not reflect the physiological differences between patients or their state of health. Obesity is a complex disease with many faces; at least two, according to a recent study published in Metabolism of nature. ” We first observed that there are at least two metabolic subtypes of obesity, each with their own physiological and molecular characteristics that affect health. “Explains Andrew Pospisilik, a researcher in epigenetics at the Van Adel Institute in the United States.

Obesity is not a matter of will and it is the science that states it

Two subtypes of obesity discovered

The first subtype of obesity discovered by scientists is characterized by the significant presence of fat mass in the body. The second is characterized by both a surplus of massmass fat and dry mass – of the muscles -, but also from very high inflammatory markers, favoring the appearance of diseases and tumors in the affected patients. Experiments carried out on mice show that this inflammation is not due to GenoaGenoa not to the environment but to epigenetics, the DNA that surrounds the genes and regulates them through different mechanisms which, in this specific case, are triggered at random.

These findings offer a nuanced view of this disease and the opportunity to diagnose it more accurately.

Our lab results are the copy carboncarbon results obtained in humans. We also observed two distinct types of obesity, one of which appears epigenetically “activatable” characterized by increased dry and fat mass, inflammatory signals and elevated insulin levels, and a strong epigenetic signature. “Says Andrew Pospisilik.

According to scientists, genes and the environment represent only 30 to 50% of who we are. The rest is dictated by something else, presumably epigenetics. ” Epigenetics can act as a switch that “turns” or “off” genes, which can promote health or, when things go wrong, disease concludes Andrea Pospisilik. Over a billion people are obese around the world. These findings offer a nuanced view of this disease and the opportunity to diagnose it more accurately.
