ObesChip® is a nutrigenetic study to help with weight control, performed using DNA from a saliva sample. It is based on a DNA biochip and analyses a total of 30 polymorphisms of 12 genes related to our genetic predisposition to obesity, energy balance, appetite regulation and response to exercise.

Nutritional genetics is the scientific discipline that relates genetics to nutrition. In recent years, adapting dietary recommendations and lifestyle habits to an individual's genetic profile has become part of clinical practice.

Which patients is it most useful for?

  • Overweight or obese people.
  • People who want to improve their diet
    and quality of life.
  • To prevent illness.
  • 185€
  • Sample:
    Blood EDTA or Saliva
  • Volume:
    4 ml
  • Storage of sample:
    5+/-3oC (away from light)
  • Turnaround time:
    30 working days
    (May vary)


ObesChip® allows dietary guidelines and recommendations on lifestyle habits to be customised with a higher chance of success, as for the first time we can concentrate on aspects where the genetic makeup is not so favourable.

What information does it provide?

Genetic predisposition to obesity

Calculation of risk based on data from genome-wide association studies (GWAS).

8 SNPs / Genes: MC4R and FTO

Energy balance

Genes related to the absorption, transport, storage and metabolism of fatty acids.


Regulation of appetite, satiety and emotional eating

Genes involved in the regulation of appetite, satiety and compulsive eating.

7 SNPs / Genes: MC4R, FTO, DRD2, OPRM1

Weight loss in response to exercise

Genes involved in the metabolism of fats in response to exercise.

3 SNPs / Genes: ADRB2, ADRB3
