This review is written with the intent to be as unbiased as possible. However, it represents the opinion of an individual reviewer and is therefore subjective. Furthermore, at Nebula Genomics we seek to educate the public about the benefits of Whole Genome Sequencing. Information about our Whole Genome Sequencing DNA test is therefore incorporated into the review.

DNAFit Introduction

DNAfit is a wellness genetic company founded in 2013 by South African Avi Lasarow. Based on genetic makeup analysis, it creates a personalized diet and fitness plan. DNAfit also offers assistance from expert sports scientists and dieticians. 

The service became part of the Prenetics Group in 2018. Recently, it partnered with Vita Mojo to create genetically-matched meals.

DNAfit is a genetic company focused on producing tests marketed towards those interested in health and wellness. It primarily offers two reports with actionable genomics advice for nutrition and fitness. After a swab test for your genetic profile, DNAfit will share personalized information that includes a detailed meal plan. 

The kits are more expensive than some alternatives, and they do not offer whole genome sequencing. However, the company does have a partnership with CircleDNA, which offers whole exome sequencing.

Did you know that most genetic tests like DNAfit decode only 0.02% – 2% of your DNA? Nebula Genomics offers Whole Genome Sequencing, a complete DNA test that decodes 100% of your DNA and enables you to learn more about your ancestry, wellness, and health than any other test!

Review of DNAfit Genetic Testing Services

DNAfit primarily offers genetic analysis with two plans: 

Diet Fit ($151): This product analyzes your genes to give actionable nutritional information. In addition, it provides a personalized meal planner with its genetic nutrition report. You will get recommendations for either a low carb diet, low-fat diet, or Mediterranean diet.

Health Fit ($174): Now known as Home Fit. This more expensive service provides the nutritional information found in Diet Fit and more. It also provides a health report, including information such as your predisposition to stress.

Because DNAfit is a subsidiary of Prenetics, it advertises the CircleDNA test. The CircleDNA test is a “whole exome sequencing” test and is more comprehensive in its analysis. 

Getting Started with DNAfit

Getting started is pretty straightforward: after ordering the DNA testing kit online, a saliva swab is delivered to your home. Once the sample collection is completed, it is sent to an accredited laboratory that will produce DNA sequencing results – within 15 days. Customers can access their genetic results using their DNAfit login on the website.

Getting started with DNAfit

It is also possible to upload Ancestry, MyHeritage, or 23andMe raw DNA data. This lets you obtain Diet or Health plans at reduced costs. ($39 for the Diet Link and $71 for the Health Link).

However, data uploads can produce different reports compared to data generated by DNAfit. In particular, a reduced amount of information is obtained from 23andMe files. 

There may be some technical difficulties (with the data format) that are not always easy to overcome.

Review of DNAfit Reports

Review of Diet Fit ($151)

This test was formerly known as DNAFit Fitness Diet Pro. When ordering this DNAfit test, specific genes associated with diet and nutrition are analyzed to produce personalized meals and optimal diet plans. 

The main information gathered through this genetic analysis is shown in the graphic below. The DietFit report can be found on its website. Among other things, you can discover if you are lactose intolerant or have a predisposition for celiac disease. Other sections of the report include things like carbohydrate & saturated fat insights and sensitivity to salt, alcohol, and caffeine.

To gain a deeper insight into the style of the report, let’s look at the breakdown of carbohydrate sensitivity, the section that describes whether you are sensitive to carbs. It shows an overview of the effects of your genotype on carbohydrate metabolism and sensitivity to insulin.

Some of the detailed suggestions, such as ways to lose weight, provide more information. This weight-loss recommendation is based on the glycemic load (GL) and index (GI) of carbohydrate-containing food. DNAFit provides tips and the below table with different carbohydrates and their GL and GI values.

A table with nutrient summary and guidelines like the one below is included at the bottom of the report:

The plan includes support from a dietician coach (one 30-minute call) and access to the MealPlanner app.

Review of Health Fit ($199) – Now Home Fit

The Home Fit report is a more complete plan that adds fitness information and personalized advice to the Diet Fit report. It analyzes your genetic data to formulate an optimal training program. 

These health and fitness results also include information on whether you have a predisposition for soft tissue injury and aerobic potential.

Furthermore, the reports contain information on recovery efficiency. This information can help you decide if you should be focusing exercise plan efforts on things like long runs or strength training to maximize your health potential.

You can read about categories such as aerobic potential and injury risk.

Do you need more endurance sports or high-intensity activity? Based on the endurance/power profile, it is possible to modulate the training activity, like endurance training.

However, a balanced training session is always advised:

Home Fit also includes support from sports scientists (one 30-minute call) and access to a training plan. 

Review of DNAfit Circle Premium ($629)

This complete plan analyzes the whole exome sequence, similar to the full genome sequencing. However, it only analyses the genes that instruct protein production (circa 1% of the human genome).

From this analysis, a DNA health report is produced that is more comprehensive than the Health Fit report. It includes disease and cancer risks; drug response; family planning, and information that is summarized in the figure below:

Review of DNAfit Privacy Policy

DNAfit, trading as Prenetics EMEA Limited, is strict about its privacy policy. The data are stored under pseudonymized IDs, and the sample is destroyed after use. However, this means that DNAfit raw data is not available for download.

DNAfit requires your permission to share the results with somebody outside the laboratory and does not sell your information to third parties. However, it may be transferred outside the European Economic Area (EEA) for processing (in which case strict measures are applied to protect it).

DNAfit labs have ISO/IEC 27001 certification for information security and management system (ISMS). ISO/IEC 27001 works as a checklist of actions to protect your organization from cyber threats. Having the certification demonstrates a high level of security. 

If you have any questions or concerns about your privacy, you can contact DNAfit via live chat, telephone, or email.
