Understanding the Basics of Nutrigenetics

Nutrigenetics is the study of the relationship between our genetic heritage and how our bodies respond to the foods we consume.

It aims to identify genes that influence how our bodies metabolize nutrients, vitamins, and minerals from our diet. Understanding these genes can help tailor our diet for better health and more effective weight management.

Our genes have an impact on many aspects of our health, including our body weight.

Some individuals can eat whatever they want without gaining weight, while others must carefully monitor their diet to maintain a healthy weight.

This connection between DNA and diet is what makes the DNA Diet Test essential.

Link Between DNA and Diet



The DNA Diet Test is a comprehensive test based on the analysis of 700,000 DNA markers.

It provides crucial information about your genetic predisposition to various nutrients, including proteins, carbohydrates, fats, vitamins, and minerals.

This data allows you to customize your diet to meet the specific needs of your body, with the assistance of a nutritionist.

How does the DNA Diet Test work?

The process is straightforward. After ordering your testing kit, you collect a saliva sample and send it to the laboratory. Scientists then analyze your genes to identify variations that influence your dietary metabolism.

You will then receive a detailed report of your results.

DNA Extraction

Extraction from the sample you send.

Your DNA contains valuable information about your genetics, which is then used to create your personalized report.

DNA Sequencing

Once the DNA is extracted, it undergoes a process called sequencing.

This means that the biological information contained in your DNA is transformed into computer data.

This computer data will serve as the raw material to create your personalized report.

Application of Algorithms

To achieve accurate and informative results, laboratories use proprietary algorithms.

These algorithms play a crucial role in transforming raw data into a detailed personalized report.

They facilitate the connection between biological information and nutritional recommendations.

Customization Based on Profile

During the initial step of genetic analysis, the laboratory identifies the participant's gender and ancestry.

Having information about origins is a fundamental step in understanding how it influences your genetics.

Understanding the Three Types of Genetic Analyses

The GWAS (Genome-Wide Association Study)

GWAS stands for Genome-Wide Association Study. This approach is a statistical study that compares the DNA markers of individuals with a particular disease or characteristic to those who do not possess it.

Multi-Variant Analysis

This approach involves analyzing a number of variants or genetic mutations, originating from one or more genes, that have a more direct connection to the sought predisposition.

Mono-Variant Analysis

Unlike multi-variant analysis, this method focuses on a single variant of a single gene to determine predisposition. This approach is used when this variant is strongly linked to the genotype.

It is important to note that the data and conclusions of genetic reports, as well as the advancements in scientific research in the field of genetics, are constantly evolving. New mutations are regularly discovered, and our understanding of those we are currently analyzing is continually progressing.

The influence of genetics on weight loss

It is common to observe how, by following a similar diet and exercise routine, some people lose weight while others do not. Genetics studies how our DNA influences the effectiveness of different types of diets.

This type of test will help you choose the best option for you.

The micronutrients our body needs may be present at abnormal levels, even if our diet is healthy and balanced. Whether they are present excessively or, on the contrary, insufficiently, inadequate levels of vitamins and minerals can have consequences.

Knowing your predispositions helps you be more attentive to certain factors and/or confirm your actual levels through analyses.

There are three related but different biological processes that can affect vitamins and minerals:

  1. Absorption: This refers to the body's ability to extract micronutrients from the foods that contain them.

  2. Storage: This involves the ability to accumulate micronutrients in certain organs of our body.

  3. Circulation: Also known as the circulatory system, it concerns the quantity of vitamins or minerals that travel through the bloodstream.

Some physiological parameters, such as cholesterol or triglyceride levels, are influenced by your DNA, determining your potential tendency to have abnormal levels.

With the DNA diet test, the laboratory can indicate your genetic predisposition and the potential consequences of having inadequate levels so that you can take the necessary measures under the supervision of a healthcare professional (doctor or nutritionist).

Other characteristics such as anxiety or addiction can also impact your health. Genetic testing can provide valuable information for anyone concerned about their health and well-being.

The Results of the DNA Diet Test

The test results will be available within 2 to 3 weeks after the laboratory receives your samples.

Once you receive your results, you will discover which categories of nutrients are essential for you. You will learn if you need more proteins, if you metabolize carbohydrates better, or if you have specific needs for vitamins and minerals.


Customizing your diet based on your genes is the key to losing weight more effectively. You can eliminate ineffective guesswork and focus on what truly works for your body. Your personalized diet will be designed to maximize weight loss while ensuring you get the essential nutrients your body needs.

This means less frustration and more results.

Should I make significant changes to my diet based on the results of my test?

Genes play a significant role in how our bodies respond to the foods we consume. They can influence how we metabolize nutrients, our sensitivity to certain food substances, and our predisposition to certain diet-related medical conditions.

However, it's crucial to remember that genes are just one aspect of the picture. Our environment, lifestyle, current diet, and other factors also influence our genetic predispositions. In other words, while genes are important, they are not the sole determinants of our health and well-being.

and maximize your health


A DNA test is by no means the same as a food intolerance test.

Genetic tests analyze your DNA to identify specific genetic markers that can influence your response to foods. In contrast, a food intolerance test assesses immune reactions to certain foods and does not rely on genetic data.

DNA tests provide an overview of your genetic profile in terms of nutrition, but this does not mean you should immediately modify your diet based on these results.

Test nutrigenetic vs. Test d'intolérance alimentaire


When you receive the results of your nutrigenetic test, it is essential not to make hasty decisions regarding your diet. You should always consult with a qualified healthcare professional, such as a nutritionist, an experienced geneticist, or your doctor.

These experts have access to detailed medical information that goes beyond the partial genetic data provided by the test. They are best equipped to interpret your results and provide recommendations tailored to your individual situation. They will take into consideration your genetic profile as well as other factors, such as your current health status, medical history, and wellness goals.

The Mediterranean Diet
The Mediterranean diet promotes the consumption of vegetables, fruits, fish, dairy products, and olive oil, while limiting meat and eggs. It is easy to follow in the long term, customizable, and associated with a reduced risk of obesity. Studies have also shown that this diet can aid in weight loss, and certain genetic variations are linked to better weight control in those who follow it.

A Low-Carbohydrate Diet
This diet restricts the amount of these essential macronutrients. Carbohydrates are divided into two categories: simple carbohydrates, providing immediate energy and found in sugars, including fruits, while complex carbohydrates ensure a constant energy supply throughout the day and are found in vegetables and cereals. Some studies suggest that genetics play a role in the ease or difficulty of losing weight. In the context of a low-carbohydrate diet, variations in the FTO gene have been associated with an increased predisposition to weight loss.

A Low-Fat Diet
This diet involves reducing the total amount of fat to less than 20% of the daily caloric intake, although the WHO considers up to 30% fat intake acceptable. It is recommended to limit saturated fats (such as those in meat, cheese, etc.) and replace them with unsaturated fats (such as olive oil, avocados, nuts, etc.). Saturated fats are solid at room temperature, while unsaturated fats remain liquid. Large weight loss studies have shown that genetic variations, such as the IRS1 variant, are associated with a better response to a low-fat diet.

The Protein Diet
It is based on increasing the consumption of protein-rich foods, such as meat and eggs. This promotes a feeling of fullness by influencing appetite-regulating hormones, including ghrelin. It proves effective for weight loss while preserving muscle mass, but it can lead to a rebound effect, ketosis, and health issues. The effectiveness of this diet varies from person to person based on genetics, with identified links to the FTO gene and its impact.
