While you can not blame the excess weight on genetics because, according to specialists, the imbalance between what is ingested and energy expenditure is largely responsible for weight gain, genetic factors also influence the development of obesity, and they account for 30 percent of the causes for which an individual gains weight more easily than others, also conditioning their response to a certain diet.

A new test, NutriCheck, evaluates the genetic predisposition to overweight by analyzing, among other variables, the way in which the organism assimilates the different nutrients. This will allow to identify the genetic variants that intervene in the control of the gain of weight and, in this way, to establish a personalized diet much more effective.

NutriCheck evaluates the genetic predisposition to overweight by analyzing, among other variables, the way in which the organism assimilates the different nutrients

Through 42 genetic variants extracted from relevant national and international scientific works, NutriCheck studies the genes involved in the way to take advantage of the nutrients of the food, the energy balance and the need to eat of the subject.

As Professor Basilio Moreno Esteban, Head of the Endocrinology, Metabolism and Nutrition Service of the Gregorio Marañón University Hospital in Madrid, explains, identifying this personal genetic predisposition will allow tailoring a diet "tailored" to the patient. The expert warns that the levels of overweight and obesity in Spain have increased significantly (38% of Spaniards suffer from obesity, and 22.9% are overweight), and that this seriously affects health because it contributes to the development of other pathologies such as diabetes, hypertension, hypercholesterolemia, hepatic steatosis (fatty liver) and sleep apnea, among others.

Nutrigenic: genetic inheritance and nutrition

Nutrigenetics is a science that studies how genes intervene in the way in which the organism reacts to different foods. And is that diet not only influences the time to gain weight, but the type of diet also increases or decreases the chances of suffering certain conditions, even in the case that the person is thin.

NutriCheck focuses on those aspects of genetic inheritance that condition the body's responses to certain dietary habits of the individual, and allows to determine the genes involved in body morphology and possible metabolic disorders. The new tool uses an oral swab to analyze these factors, and the result will be a nutrigenetic profile of the patient that will help a medical professional to determine which is the most suitable diet for him, with an individualized diet that will not only prevent him from developing Overweight, obesity and other associated pathologies, but it will provide the necessary nutrients for your body to function properly.
