Nutrigenomics is the study of food on a genetic level. What if a dieter could send off a blood sample and receive a personally tailored diet based on that blood test? According to experts in the field of nutrigenomics, that is exactly what the dieting industry is working toward. The field of nutrigenomics specifically notes how foods are metabolized, absorbed and expelled for detailed look into how the body reacts to given foods. Foods that metabolize and absorb faster and better are likely to be healthier and better suited for a weight loss diet. Foods that slowly metabolize will be avoided.

Dieters currently choose diets and foods based on clinical research, diet studies and consumer testimonials. Just because one diet works for thousands of people does not mean it will work for them. According to nutrigenomics, everybody metabolizes and absorbs foods, vitamins and nutrients differently. With proper testing, geneticists can test foods on a per-person basis and suggest diets to improve health, prevent disease and increase metabolism.

In the field of nutrigenomics, foods are broken down into specific nutrients. Nutrients are viewed as signals to the cell. Some signals tell cellular metabolism to speed up and others tell cellular metabolism to slow down. If a dieter were to eat foods that constantly promoted increased metabolism, achieving and maintaining a healthy weight would be as simple as eating foods from the prescribed list. Each person would have a different list of approved foods.

Currently, nutrigenomics is in the research stage. Papers have been published on the effects of nutrigenomics on animals, but testing has not reached the human level. In the future, nutrigenomics could provide the answer to nutrition based disease prevention, weight loss, muscle growth and more.

There are limitations to be expected when research reaches a human testing level. Blood tests would likely be expensive and diets would need to be changed constantly to match current gene and cellular reaction to foods. As the dieter lost weight, the body would react differently to foods and thus a new test would be required and more money spent.

  • Gene-based diet for weight loss.
  • Could help prevent diseases like type 2 diabetes.


  • Tests would likely be expensive.
  • Testing would be required often.
  • Diets would need to be changed constantly.


Nutrigenomics is the study of how the body reacts to nutrients. Some nutrients slow down metabolism while others speed it up. Ideally, the dieter would be prescribed a diet that would increase metabolism based upon their cellular genetic panel. If research finds the key between cells and food, obesity could be a thing of the past.
