How do I get personalized nutrition recommendations from DNA tests?

You receive personalized nutrition recommendations from a DNA test in four steps: You order a test kit, provide a sample at home, provide a saliva sample, and an ISO-certified laboratory analyzes your genetic markers related to metabolism and nutrient utilization, and you you then receive a digital report with concrete recommendations for carbohydrates, fats, proteins, and vitamins.

At mybody®, three DNA tests in particular provide these nutrition recommendations as a core component: the NutriCare INFINITY DNA test, the WeightLoss SLIM DNA test and the comprehensive Longevity ALL IN ONE DNA test. All three work with a simple saliva sample. Further down, we show you exactly how the process works, what is specifically analyzed, and which test best suits your goal.

How to get your DNA nutrition recommendations in 4 steps

What exactly does a DNA nutrition test analyze?

A DNA nutrition test examines genetic markers that influence how efficiently your body processes fats, carbohydrates, and proteins. It also shows how strongly your sense of satiety is genetically pronounced how your body metabolizes caffeine and whether you have an increased genetic whether you have a sensitivity to lactose or gluten.

The analysis also provides information about how well you absorb certain vitamins such as B12, D3, or folate. This combination of metabolic, satiety, and vitamin markers results in a a nutritional profile that referred to scientifically as nutrigenetics—nutrition based on your individual genes rather than based on blanket diet rules.

The 3 mybody® DNA tests with a focus on nutrition compared

The 3 nutrition DNA tests in detail

1. WeightLoss | SLIM DNA test

The starting point if your nutrition goals are closely linked to your weight.

Suitable for: People who barely lose weight despite dieting and want to understand whether they are more of a “fat burner” or a “carbohydrate type.”

Analyzes genetic tendencies related to fat and carbohydrate metabolism and appetite regulation using a saliva sample. Price: €169. Results in 15–25 business days.

Conclusion: A good starting point if nutrition is primarily relevant to you in the context of weight management.

2. NutriCare | INFINITY DNA Test

The specialized nutrition test: How your body processes macronutrients and which vitamins it particularly needs.

Suitable for: People who want to adapt their diet to their genetics not only for weight loss, but in general—for more energy and well-being.

Analyzes how your metabolism responds to fats, carbohydrates, and proteins, which vitamins and minerals you particularly need, and whether genetic sensitivities to certain foods exist. Price: €269. Results in 15–25 business days. Optionally available with a 28-day meal plan and recipe book.

Conclusion: The test with the most direct focus on personalized nutrition recommendations in the mybody® range.

3. Longevity | ALL IN ONE DNA Test

The most comprehensive analysis if you want to understand nutrition not in isolation, but as part of your overall health.

Suitable for: People who want insights into fitness, skin health, and general longevity in one test in addition to nutrition recommendations.

Combines nutrition, metabolism, and vitality analysis in one comprehensive DNA test. Price: €369 (instead of €629). Results in 15–25 business days.

Conclusion: The right choice if you want to understand not only what you should eat, but your overall profile.

Why does your DNA influence your diet at all?

Your genes determine, among other things, how efficiently enzymes process fats and proteins or break down carbohydrates, how quickly you feel full, and how high your genetic risk of insulin resistance or elevated cholesterol levels is and how well your body absorbs vitamins such as B12, D3, or folate. Your explains why some people gain weight despite an apparently healthy diet gain weight, while others barely need to pay attention to their calorie intake.

Without this genetic knowledge, many people turn to generic dietary rules that are not at all optimal for their individual metabolism are—with correspondingly frustrating results. A DNA nutrition test makes these hidden connections visible and replaces guesswork through a specific approach based on your biology.

Typical reasons standard diets don’t work for you

When a diet doesn’t work for you, it’s rarely due to a lack of discipline. Often, several factors interact: a genetic impaired processing of fats or carbohydrates, an imbalance in the gut flora that impairs nutrient absorption, as well as hormonal influences caused by stress or lack of sleep.

Undiscovered nutrient deficiencies, such as vitamin D, magnesium, or B12, and undetected food intolerances can also mean that that an otherwise sensible dietary change does not produce the expected effect. A DNA test covers the genetic component of these causes to provide a more complete picture, the result can be meaningfully combined with a microbiome or nutrient blood test.

How reliable are DNA-based nutrition recommendations?

DNA nutrition tests are based on genetic markers that have been studied in scientific research. Reputable providers use only markers supported by peer-reviewed publications, and have the analysis carried out in ISO-certified laboratories.

Wichtig für die Einordnung: DNA-Tests zeigen Tendenzen und genetic probabilities, not definitive diagnoses, and no 100% guarantee of success for a specific diet. Your genes do not change, but lifestyle, exercise, stress, and sleep also influence how your genetic predisposition actually affects you. A DNA nutrition test therefore provides a well-founded starting point—you achieve the best results when you combine the recommendations with your individual lifestyle.

Which dietary patterns may emerge from your DNA profile?

Depending on your genetic profile, your report may suggest different dietary approaches: from low-carb or keto (low in carbohydrates high-fat) to high-protein (ideal for building muscle), through Mediterranean diet, which has particularly strong scientific support for heart health and healthy aging.

Plant-based diets and low-fat approaches may also be recommended for fat metabolism issues, or an anti-inflammatory diet for A focus on omega-3 and antioxidants may emerge from your profile The key advantage: You no longer have to try things various diets at random; instead, you start directly with the direction that statistically best matches your genetics.

What's important is that the report gives you guidance, not a rigid pressure. You remain free to decide how you implement the recommendations integrate into your everyday life—for example, gradually over several weeks instead of with a radical dietary change from one day to the next. Many mybody® customers also combine their DNA recommendations with a free consultation to clarify any open questions about practical to clarify how to put it into practice in everyday life.
