How Does DNA Testing for Weight Loss Work?

DNA tests for weight loss examine certain genetic markers in your DNA to determine different hereditary traits, and how each could influence your weight loss efforts.

By being aware of these traits, you can adapt your weight loss strategy to work with your body and not against it. You can choose the diets and exercise regimens that will give you the best chance of achieving and maintaining your goals.

Does Genetics Affect Weight?

Your DNA can have a strong influence on genetic traits such as the speed of your metabolism, your tendency to regain weight after dieting, and your tendency to crave food when you’re stressed. Some genes can even increase your overall likelihood of being overweight.

Researchers have done genomic testing of large numbers of people and have found correlations between certain gene markers and these traits. Some of these correlations are stronger than others.

So, DNA tests for weight management tend to look for those weight-related gene markers that are supported by the most well-validated science.

Can a DNA Test Help You with Weight Loss?

Yes, a DNA test can help you with weight loss. For example, many people have lost weight successfully by going on low-fat diets. But people with a certain type of genetic fat metabolism are less likely to benefit from a low-fat diet than other people. If you’re one of these people, you should probably try a different weight-loss strategy.

Another genetic trait involves carbohydrate metabolism. Knowing about your genetic tendencies around metabolizing carbohydrates can help you decide whether a low-carb diet is likely to work for you.

Similarly, some people are more likely to regain weight quickly after dieting than others. If you find out you’re one of these people, it’s even more important for you than for most people to choose a diet regimen you can stick to for the long haul.

Does DNA Fitness Testing Tell Me My Optimal Workout Routine?

Just as genes can affect your body’s traits involving weight and weight loss, genes can also help determine your body’s response to exercise. For example, they can influence whether you’re more well-suited to endurance or short bursts of high speed.

Genes can also affect your ability to build muscle mass, your risk of muscle injury, and other factors. By understanding your genetic tendencies in these areas, you may be able to make more well-informed choices as to what type of workout strategy your body will respond to best.

How We Compared the Top Diet and Fitness DNA Tests

To make our list of the best DNA tests for weight loss and fitness, we looked at several important factors that could affect your satisfaction with your results.

  • Accuracy – We looked at what genetic markers each test’s conclusions were based on. Then we verified that there’s respectable research to support those conclusions.
  • Believability – We evaluated whether our own test results rang true, considering what we know about our own bodies.
  • Accessibility – We looked at whether the reports did a good job of explaining our results in language an average person could understand.
  • Actionability – Do you get practical, tangible recommendations on how to optimize your weight loss and fitness pursuits? Features like customized meal plans and exercise regimes helped tests rank higher on our list.

How Do You Read and Interpret the Results of Your Diet and Fitness Report?

Most DNA results are delivered via reports that you can access on a company’s website, mobile app, or both. These reports explain what genetic traits you have that can affect your diet and exercise plans.

Most companies point out how large or small a role these traits play in comparison to various lifestyle factors. The reports will generally detail what specific genetic markers led the company to reach these conclusions about you.

The best diet and fitness reports will then also tell you what to do given the traits that you have (i.e., how to tailor your diet and fitness strategies to be more successful).

How Accurate Are the DNA Test Results?

DNA test results can vary in accuracy, for several reasons. First of all, while the conclusions are (hopefully!) based on reputable major scientific research studies, some of the correlations noted in those studies are stronger than others.

Also, a single genetic marker may not tell the full story about whether you’re likely to have a particular trait. The best DNA tests will look at a blend of markers, and explain how strong the evidence is tying each marker to that particular trait.

Finally, genetics isn’t destiny. Your test may say you’re likely to have a certain tendency, but depending on your lifestyle and your life history, you may or may not have developed that trait (or noticed whether you have it).

The best thing you can do with your DNA report is to try it on for size. If your report’s conclusions ring true, try following its recommendations and see if they help you attain your goals. Many people have gotten very good results from doing this!

Can Customer Service Answer All Your Questions?

Customer service is an area where different DNA testing companies can vary significantly in quality.

First of all, most sites have FAQ sections where you might find the answers you’re looking for. But if not, you can usually get support by calling on the phone, sending an email, filling out a request form on the website, or doing a live chat with a customer service representative.

Some companies are very responsive, and others can take a long time to respond to your inquiries. Either way, how good of an answer you get depends on the person who’s providing it. Some companies’ customer service representatives are much more knowledgeable and well trained than others.

If you don’t get a satisfactory answer, you can always try again, and/or ask to speak to a supervisor – just like you would with any other product or service.

Which DNA Test Offers the Best Value?

DNA tests for diet and fitness can vary greatly in price. But deciding on the value of a DNA test is quite a bit more complicated than that.

It really comes down to the information and features that are the most important to you. If you primarily focused on determining your optimal diet, Gene Food provides huge value. Not only will you get assigned one of 20 different ideal diet types, based on your DNA, but you’ll get tons of helpful reports and a two-week meal plan.

Maybe you are someone who needs to actively be monitoring things like your metabolism or vitamin levels. If so, a blood test from Everlywell can be hugely beneficial. This measures your current levels as opposed to your genetic predisposition, so the overall value again depends on your specific needs.

Or, if you are more concerned with improving your overall lifestyle, Living DNA could provide the most value. You will get actionable recommendations that can help you become a healthier person, both in the gym and in the kitchen.

Before you decide which test is right for you, think about your end goal. Reading our expert reviews will help you feel confident about your experience, and is also a good way to make sure that you get the absolute best price.


What can a DNA test tell you about your weight?

A DNA test can give you feedback on a number of genetic traits that can influence your weight and your ability to lose it.

First of all, the test can tell you if you’re genetically more likely to be overweight than other people, based on whether you have certain gene markers that have been linked to this.

A DNA test can also tell you things about how your body is genetically inclined to process fat and carbohydrates, whether you might be prone to stress eating, how likely you are to feel full after eating, and even your tendency to regain weight after you’ve lost it.

A DNA test can also tell you how helpful exercising could be in your weight loss efforts – and what types of exercising, in particular. Knowing all these things about yourself can help you make more informed food choices and develop more effective weight management strategies.

What can a DNA test tell you about your relationship with nutrition and food?

First of all, a DNA test can tell if you might tend to have trouble absorbing certain vitamins and nutrients. Knowing this can help you avoid potentially dangerous nutritional deficiencies.

A DNA test can also tell you if you may have food sensitivities that would make it harder for you to digest things like gluten and lactose. You may also learn about your genetic relationship with alcohol, like whether you are more or less likely to flush and get hangovers than most people.

You can even find out whether you may tend to drink more or less caffeine than other people do!

What common food sensitivities does a diet DNA test screen for?

The most common food sensitivities included on DNA reports involve gluten and lactose intolerance. Some tests will also tell you if you’re likely to have a peanut allergy. You can check out the best DNA tests for food sensitivities to learn more.

It’s worth noting that the scientific basis for these tendencies isn’t as rock-solid as it is for some other genetic traits. In other words, there’s not an incredibly powerful correlation between the gene markers that DNA tests look at and your likelihood of having or not having these food sensitivities.

So, just because a DNA test tells you that you may be genetically prone to lactose intolerance, that doesn’t mean you actually are. And just because it says you’re not genetically prone to lactose intolerance, that doesn’t mean you’re actually not.

When you read about these things on your DNA report, compare them to your personal experience. You shouldn’t just accept them at face value – because these food sensitivities aren’t all that simple to predict via DNA.

Can you use a diet and fitness DNA test to determine your optimal diet plan?

At the very least, a diet and fitness DNA test will educate you about your genetic tendencies involving bodyweight, satiety (feeling full), stress eating, weight regain after dieting, and fat and carbohydrate metabolism.

Knowing that kind of information can help you make more informed dieting choices. But the best DNA tests in this category will also give you specific, tangible suggestions for what you can do to reach your weight goals. Some even give you sample menus and recipes.

What can these tests tell you about your overall fitness?

A DNA test can tell you how your genes might affect your fitness efforts – for example, how easily you may be able to build muscle mass, or whether you’re better geared for endurance or speed. But it can’t tell you how fit you are. Your actual fitness depends on you.

You’re the one who chooses to exercise or not, what exercises to do, and how often or how long you do them. Your fitness also depends on your age and your lifelong history of physical activity.

And just because a DNA test tells you that you may have trouble building muscle mass, that doesn’t mean you can’t build muscle mass. It just means you may have to work harder.

A DNA test can also tell you how easily you may injure yourself while exercising…so you’ll have a better idea how safe or dangerous it may be to push yourself a little harder.

Can a diet and fitness DNA report provide meal or exercise plans?

Not all diet and fitness DNA reports provide meal or exercise plans, but some of them do. So if that’s important to you, make sure you read what comes with each company’s test. Some of the companies’ websites are more forthcoming about what’s included than others – this is always something our DNAWeekly reviewers look for when we evaluate a DNA diet test kit.

The depth of the reports can vary greatly. For example, Living DNA makes exercise recommendations like if you should use lighter weights with more reps or heavier weights with fewer reps. In Rightangled’s training plan, you’ll get advice regarding how many cardio and yoga sessions to do each week, plus you have access to a personal trainer.

Can you work with a nutritionist or dietician after taking a DNA test?

You certainly can, and you probably should!

While a DNA test can tell you a lot about your genetic tendencies around nutrition and dieting, it’s no substitute for the advice of a trained professional.

A nutritionist can help you determine whether you actually have certain nutritional deficiencies, and can recommend a sound strategy to compensate for them.

A dietician can give you feedback on how healthy and likely to succeed your weight loss plan is, and what you can do to make it better or safer.

We suggest that you first look into the top nutrition DNA tests. Once you receive your results, make an appointment with a nutritionist to go over them and create an actionable plan.
