How We Tested At-home Diet and Fitness Testing Kits

To determine the best DNA tests for diet and fitness, we looked at several important criteria:

  • Reliability – We researched the genetic markers used to form conclusions and recommendations. Consulting reliable resources ensured peer-reviewed research backed up their insights.
  • Clarity – We established that each report provided extensive conclusions presented in accessible language. The tests that explained the conclusions ranked higher than those that provided only basic reports.
  • Actionability – Do you get practical, tangible recommendations on how to optimize your diet and fitness regimes? Features like customized meal and exercise helped tests rank higher on our list.
  • Relevance –  Does the test analyze a wide range of dietary and fitness factors?
  • Support – It’s much easier to get your head around the results of a DNA test when support from experts is available, whether that be through consultations or a useful knowledge base.

How Do You Read and Interpret the Results of Your At-Home Diet and Fitness DNA Test?

Once the analysis is complete, your reports are made available, which include a number of insights based on your genetics along with details on how these conclusions were reached.

You won’t have to interpret your own data – experts use their wealth of knowledge to provide useful observations on how your genetic traits influence your body’s response to diet and exercise.

The best diet and fitness reports will provide actionable advice based on your unique genetic makeup, which can include which foods to add or eliminate from your diet, as well as other lifestyle changes, to improve your health and wellbeing.

How Does At-Home Diet and Fitness DNA Testing Work?

Collecting your DNA sample at home is simple, with most providers – including Living DNA, GenePlanet, GenoPalate, and Vitagene– requiring a small amount of saliva or cheek swab. A few tests, like TeloYears, may require a blood sample, but this is easily provided with a painless finger-prick kit.

The best diet and fitness DNA tests include pre-paid packaging so you can drop your samples directly in the mail. Once the lab receives your sample, your DNA is carefully analyzed to reveal your diet and fitness traits.

What Will Diet and Fitness DNA Test Results Tell Me?

Your results are usually processed within six weeks of the lab receiving your sample. As Everlywell and InsideTrackertest for biomarkers in blood, results are issued in just five to seven days. Your report is delivered to a secure online account and you’ll be emailed when they become available.

Depending on which test you choose, your results may show how your body processes certain nutrients and how it responds to different types of exercise. In most cases, along with these conclusions, are tailor-made insights on how you can optimize your diet and exercise regimes, based on your DNA.

How Accurate are Diet and Fitness DNA Tests?

While the majority of diet and fitness DNA tests are highly accurate, there are several factors that can affect accuracy. The DNA or blood sample you provide must be of high quality. If you don’t swab for long enough, or follow the instructions of finger-prick blood collection correctly, your sample may not contain enough genetic material or be contaminated.

Scientific research also has a role to play in results accuracy. Conclusions are based on reputable studies, however, some of the correlations are stronger than others, and some genetic markers are better understood. Therefore, a single genetic marker is unlikely to tell the full story for a particular trait. The best DNA tests will analyze several markers to create a fuller picture.

Finally, your genes are not your destiny. Your test may indicate a genetic predisposition or trait, but your lifestyle choices and environment may play a greater role, particularly in fitness and dietary factors.

Use the results from Living DNA and GenoPalate to guide lifestyle changes and monitor any improvements in a trial and error process.

How Much Does a Diet and Fitness DNA Test Cost?

Diet and fitness DNA tests vary by provider, but most range between $50 and $200, depending on how extensive your results report is. When choosing a DNA test, the price shouldn’t be the deciding factor. Take a look at what you get from the test to determine the best value.

Some tests only analyze the genetic influence on nutrition and diet, which may be sufficient if you’re interested in eating better. Others will also look at markers that may determine how your body will respond to exercise. This information can prove useful if you’re interested in maximizing performance.

The most comprehensive tests will offer additional insights, such as food sensitivities and recovery reports, as well as personalized meal and exercise plans to kickstart your new healthy regime.

The Bottom Line

The diet and fitness DNA test you choose is dependent on how much information you need. The best all-around diet and fitness test is from Living DNA, thanks to actionable reports for an affordable price. If your primary concern is eating better, go with GenoPalate, or if you want to boost your fitness performance choose DNAfit. If you need additional support in the form of tailor-made recipes or meal plans, Vitagene and Gene Food are good choices


What is a diet and fitness DNA Test?

Diet and fitness tests assess your DNA, screening for genetic markers that have been linked to nutrition and fitness traits.

This genetic information is used to draw conclusions on the best foods and exercises for your unique makeup, which may help you reach your health and wellness goals faster.

What sample is needed for diet and fitness DNA testing?

Most at-home diet and fitness DNA tests use a saliva sample, obtained from a simple cheek swab. Ins some cases, such as when analyzing biomarkers instead of genes – testing is performed using a finger-prick blood sample.

Does genetics affect weight?

Yes, to a certain degree. Research has shown a genetic link to a number of traits, such as metabolism and the tendency to store fat, but it isn’t the whole story. The strength of genetic influence on weight varies between individuals; for some people, genes account for as little as 25% of the predisposition to be overweight, while for others it could be as high as 80%.

Plus, your genes can also influence which weight-loss strategies – including types of diet and workout – may work best for you.

Environmental and lifestyle choices also play a key role in weight, so a diet and fitness DNA test can provide you useful tips on what changes you can make to be healthier in general.

Can DNA testing tell me my optimal diet and workout regimes?

Most DNA tests will provide actionable insights in your results reports, for example, what food you should include in your diet, any vitamin deficiencies, and what exercises are best suited to your genetic makeup. This information provides a great start on your journey to a healthier lifestyle

Some companies, such as DNAfit and Vitagene, offer customized diet and fitness plans, which have been guided by your generic predispositions. This makes it super easy to start eating better and maximizing your performance in the gym.

What can’t DNA tell us about diet and fitness?

By analyzing known genetic markers, DNA tests can tell us if we are predisposed to certain traits related to nutrition and fitness, such as vitamin metabolism, macronutrient breakdown, and strength and recovery response.

However, correlation does not equal causation. Just because a certain gene has been linked to a particular trait, it’s not a guarantee you’ll exhibit that trait if you have the gene, especially since lifestyle plays such a big role.

What a DNA test can do, is to help you to make better choices by giving you an indication about what foods and exercises are likely to work better with your body.

They are no substitute for advice from a trained professional and no major lifestyle changes shouldn’t be made without first consulting with your doctor.
