Best DNA Test for Fitness & Diet Plans: Which Test Is The Best?

Thinking about getting a DNA test to help with fitness and diet planning?

You’ve come to the right place. 

Consumer DNA testing has exploded in the last few years. More and more people are curious about their heritage and the family secrets their DNA holds.

We are now beginning to use DNA tests to learn more about our health, including genetic diseases we are at risk of and whether we might pass on certain conditions to our children.

But there’s a lot more that a DNA test can uncover beyond your ancestry and health risks.

Fitness and diet DNA testing is a new field that uses DNA test results to inform and personalize diet and fitness plans.

These tests are based on the yet to be completely proven theory that DNA can reveal your body’s optimal diet and fitness needs.

To be clear, there isn’t yet enough scientific research done on whether you can completely tailor a diet or fitness plan based solely on your DNA.  This is why all of the tests below include more than DNA test results.

Regardless of which test you buy, it is important that you consult with your doctor, your nutritionist and/or your trainer before taking actions based solely on a DNA test result.

OK, with those caveats out of the way – let’s see what the state of the science CAN tell us.

What is a DNA Diet / Fitness Test?

dna fitness testing

Your DNA holds telltale clues that a lab can use to pinpoint your ancestry, trace your mother’s or father’s line, and even match you to unknown family members.

Companies like 23andMe can now use these genetic markers to approximate your risk of getting various genetic diseases.

A Diet and Fitness DNA test is just the latest way of using genetic markers to inform and guide your life.

But instead of checking DNA for ancestry information or health risks, DNA fitness and diet tests look at different DNA markers that are related to your metabolism and other medical conditions to guide your training and nutrition.

DNA fitness testing starts with the exact same process an ancestry or health test uses. You spit in a tube or take a cheek swab and send your DNA sample in to a lab for testing.

Some companies like DNAFit also accept raw data from other DNA testing websites such as 23andMe and MyHeritage.

The lab then tests your DNA for specific genetic variants.

If you have a variant associated with lactose intolerance, the report will tell you that.

If you have a variant associated with increased strength and endurance, the report might recommend a change in your workout routine.

And if your DNA shows that you metabolize certain types of foods better than others, the report will recommend a specific diet.

What Can You Learn From a DNA Fitness and Diet test?

dna fitness testing

Here are some of the things you can learn from a DNA-based fitness and diet test:

  • The best foods and diet for you. The report might tell you that your body is better suited to a Mediterranean diet or that your body responds better to a low-fat diet.
  • How your body responds to different types of food. Finding out how your body responds to carbs, proteins and, fats can help you lose weight more quickly and get fitter.
  • Whether you are at risk of lactose intolerance, gluten intolerance or intolerance to other types of food .
  • Your fitness traits. The test might explain why you take longer to recover, why you find running easier than weight training and why you gain muscles slower than most people.
  • The best workout plan for your body. Based on your DNA, the test report will recommend which fitness plan will get you the best results.
  • Best workouts to avoid injury. Some tests also tell you how you are genetically predisposed to certain injuries and how to modify your workouts to reduce the risk of injury.
  • How to improve athletic performance. Some tests are aimed at professional athletes. The reports contain in-depth data and information on how to optimize areas like speed, endurance, and strength.

As I mentioned before, be careful about what you decide to do based solely on these results.

The science on how DNA and diet/fitness are connected is still young.

Your report will contain a lot of useful information, but it may also include information that is wrong or misleading.

So before you completely overhaul your diet or workout plan, talk to an expert.

Uploading Your Raw DNA Data

dna fitness testing
23AndMe Raw Data browser

Most companies require that you provide a sample for DNA testing. But a few allow you to upload raw DNA data if you have already tested with another company like 23andMe or AncestryDNA.

Check the company’s requirements before you upload raw data. Some accept raw data only from specific companies.

Something else to keep in mind when uploading raw data: make sure you upload the right file. It will most likely be in a .txt format.

Do not upload your DNA report from another company (which will most likely be in a .pdf format). That’s just the summary. What you need is the unfiltered raw data.

Mixed Results Are Common

dna fitness testing

The whole idea of using DNA to recommend the best workout and diet plans is way ahead of where science currently is.

As a result, DNA reports are not always 100% accurate or reliable. Some of the insights included are just approximations, and others are just generalized ideas that apply to most people.

That’s why it is important to consult a doctor before taking any major action based on your DNA fitness testing results.

If you want to see just how confusing the tests can be, try testing with two or more companies.

Several people have tried, and the results were baffling.

They got very different pictures from each company with some aspects of the reports flat out to contradict each other.

To be sure, this is not an issue with DNA testing in general.

If you take an ancestry DNA test with different companies, the results will roughly be the same. What might be different is how they each have divided the world, and what they call various regions.

DNA fitness testing, on the other hand, varies wildly from one company to the other.

One report might tell you that you perform better at speed-focused sports activities while another says you are better suited to strength-based sports.

You might discover that you are a low-fat kind of person only for another test to tell you that reducing carbs is better for your metabolism.

Even tests that discover the same genes in your DNA might interpret them very differently.

The Main Issue: Research

The biggest issue, it seems, is the research that these companies rely on.

When it comes to ancestry testing, there is a lot of solid research on variants associated with different populations. That’s why your ancestry report doesn’t change much from one company to another.

There is also a lot of good research on genetically inherited diseases and the genes that cause them.

If you take 23andMe’s health test, you’ll discover you are at risk of roughly the same conditions that another DNA health screening will find.

But when it comes to fitness and diet testing, there is little proven research.

Many studies suggest there is a link between DNA and your fitness and diet, but we have yet to pin down the exact association between specific genes and your ideal sport or perfect weight loss diet.

Part of the reason is that there are so many other factors beyond genetics that influence weight loss, fitness, and overall health.

The available research is conflicting and in most cases, inconclusive. So diet and fitness reports, which rely on this research, are also often inconclusive.

Your report will contain some helpful insights. But it could also include unhelpful recommendations.

That’s why I keep emphasizing you work with an expert – a doctor, dietician, nutritionist or physical therapist –to modify your diet or workouts based on the report.

What The Science Says So Far

dna fitness testing

Even science itself can be a bit confusing when it comes to DNA-based diet and fitness tests. Again, the problem is conflicting and inconclusive studies.

But the general take for most experts is that the DNA diet and fitness testing is still an unproven ground. It has some benefits, but it’s unwise to rely only on a DNA test to inform your diet and exercise decisions.

Here are some of the main takeaways from various experts and studies.

  • There is some evidence that genetics can influence how your body processes carbs, proteins, and fats. But there is no evidence, that changing your diet based on this information helps with weight loss or fitness.
  • Research suggests that genetic variations among individuals do not result in a significant difference in the effect of specific diets and exercises. There very little difference in the amount of weight lost between two groups with different genetic variants following the same diet and exercise regimen. This shows that other factors like lifestyle have a much bigger impact on your weight and fitness than your genetic variants.
  • The effect of various genes varies widely from one population to another. Research involving Caucasian participants may not translate well to Asian or black people. And since most studies involve people with European origins, the little we know about DNA and diet/fitness may not apply to other races.
  • There are many other genes that labs don’t test for and whose effect on our health and fitness we don’t know. One known gene may cause some people to store more fat than usual, but we don’t know whether there are other genes that might also affect their fat intake.
  • A couple of studies have shown that providing personalized dieting and fitness information makes individuals more likely to make positive changes to their lifestyle and stick to them.

The Bottom Line

You can get some useful information from a DNA diet or fitness test.

But don’t feel that you have to get a diet or fitness DNA test if you want to lose weight or get ripped.

Most of these tests tell you what you already know (workout more, eat more vegetables, avoid caffeine at night, etc.) or things that you can’t translate into practical changes.

If you do decide to get a DNA test, be careful how you integrate the recommendations into your lifestyle.

Some suggestions like taking yoga to improve joint health or eating more Omega-3 foods are harmless and even beneficial.

Others recommendations like switching to a low-carb diet to lose weight can be dangerous for your health if you are not careful.

For the major stuff, ask your doctor before doing anything.
