6 Best DNA Tests for Weight Loss in 2024

By using a DNA test kit for weight loss, you can unlock personal genetic insights and tailor your strategies to better fit your body’s unique needs, eliminating the guesswork and unnecessary frustrations. However, not all DNA kits are made the same, and not all of them will give you the information you need to get started.

Price from$159.00
Our score8.5

Everlywell takes a slightly different approach to weight loss than the other kits on this list. It has a few different options available, and we like the thyroid and metabolism tests best.

With the metabolism test, we were able to learn about the three key hormones: cortisol, free testosterone, and TSH. Our report showed whether our researcher’s levels were high, medium, or low, with advice on how these hormones might affect weight loss.

You can also buy a dedicated thyroid kit, which we’ve also tested. This screens for T3, T4, and TSH. Our colleague not only learned about his overall thyroid function, but also how the thyroid gland can affect his weight loss goals. For example, he had a particularly low level of T3 and his report explained how this can lead to weight gain.

No matter which test you choose, sample collection is really easy. Our kit came with detailed instructions and all the equipment you need to take the finger-prick blood sample. It’s painless.

We were impressed with the results times, too. It only took 3 days to get our reports, which are available from your online dashboard.

Our colleague’s report was nicely color-coded so he could identify any concerns with hormone levels, and also see how his levels compared to normal averages.

We also liked that you can pay with HSA/FSA cards to save some dollars. And there’s a subscription option which is a great feature for regular weight loss testing.

What We Look For in the Best Weight Loss DNA Tests

Consider these essential criteria when choosing a DNA test for weight loss. While their importance may vary based on your personal preferences, keep them in mind during your decision-making process.

  • Trustworthiness: Evaluate the company’s reputation. Have people achieved positive outcomes using the DNA findings provided by the company?
  • Relevance: Check if the company offers one or more tests specifically designed to address weight loss concerns.
  • Report clarity: Ensure that your DNA results are coherent and easy to comprehend. Do they make sense to you?
  • Actionability: Assess whether your report presents clear and actionable strategies, plans, and recipes tailored to your unique genetic predispositions, helping you implement effective diet and fitness approaches.

How DNA Testing For Weight Loss Works

Your DNA contains unique markers influencing your body’s processes related to digesting food, absorbing nutrients, and engaging in physical activity. Understanding these markers can pave the way for a personalized approach to managing weight. Genes like FTO and MC4R play roles in regulating appetite and fat storage, while PPARG impacts your body’s insulin response. DNA tests examining these markers can provide tailored advice on diet and exercise, specifically aligned with your genetic makeup.

Why You Should Take a DNA Test for Weight Loss

Taking a DNA test before planning a diet can offer insights that general recommendations cannot. While conventional diets operate on a one-size-fits-all principle, a DNA-based diet can identify your individual carbohydrate and fat sensitivities, or your likelihood to regain weight after losing it. This makes your approach to weight loss more efficient and tailored to you, potentially improving adherence and long-term success.

Can Children Get a DNA Test for Weight Loss?

Yes, children can get DNA-tested for weight management, but consult a healthcare provider first. Children’s nutritional needs differ from adults, and using genetic information for weight management in minors can be sensitive. Medical professionals can offer guidance on whether such a test is appropriate and how to interpret the results in the context of a child’s overall health and development.

Can DNA Testing Give You Fitness Information?

Beyond diet, DNA testing can also assist in shaping an effective fitness plan. Genes like ACTN3, which are associated with muscle composition, and VEGFR, related to cardiovascular fitness, can be crucial. These genetic markers can guide you on whether you might benefit more from high-intensity exercises, endurance training, or a balance of both. This allows you to maximize the impact of your workouts, making your fitness journey more efficient.

What’s in the Fine Print?

When selecting DNA tests for weight loss, it’s important to carefully read the terms and conditions, as they may contain crucial details affecting your experience and the test’s limitations.

For example, Living DNA offers a comprehensive weight management test, but its fine print indicates that your data may be used to improve their services. Everlywell prioritizes privacy, but requires a subscription for access to tailored meal plans and ongoing support. Be sure to understand their pricing and cancellation policies to avoid unforeseen complications.

My Toolbox Genomics provides in-depth insights, but their disclaimer states that the information should not be used for medical diagnosis or treatment. Always consult a healthcare professional before making health-related decisions based on these insights.

Scrutinizing the fine print helps you choose the most suitable DNA test to achieve your weight loss goals.

Payment Options for DNA Testing Services: HSA/FSA Cards and Insurance

The ability to pay for DNA testing services using Health Savings Accounts (HSA), Flexible Spending Accounts (FSA), or insurance varies depending on the company and the nature of the test. Here’s a breakdown for some popular DNA testing services:

  1. LivingDNA: Generally, LivingDNA does not accept HSA/FSA cards or insurance. Their focus is mostly on ancestry testing, which usually is not covered by these payment options.
  2. MyToolbox Genomics: This company specializes in health-focused testing, including weight loss. They don’t accept insurance but their tests are eligible for HSA/FSA.
  3. SelfDecode: SelfDecode offers comprehensive genetic reports aimed at personalized health advice. While they provide valuable health-related insights, they also do not currently accept HSA/FSA or insurance payments.
  4. Inside Tracker: Inside Tracker provides blood and DNA analysis to give nutritional and lifestyle advice. Some of their tests may be eligible for HSA/FSA reimbursement, but it is advisable to check with your account provider first. They generally do not accept insurance.
  5. Everlywell: Everlywell offers a range of tests, including some that focus on health and wellness. They do accept HSA/FSA cards for payment but do not accept insurance.

If you’re considering using HSA/FSA cards or insurance to pay for a DNA test, always confirm eligibility with your account provider and read the fine print. Some services may provide you with a detailed invoice that you can submit to your insurance for a potential reimbursement, but this is not guaranteed. Always consult your healthcare provider and insurance company for specific advice tailored to your needs.

How Do Our Top Picks Compete On Price?

In terms of value for money, it doesn’t get much better than Living DNA. This is my top choice because it’s affordable, only costing you just over $125, and it gives you way more information than you’d expect for that price, including food sensitivities and a full exercise breakdown.

If you’re looking for a cheaper option, Everlywell comes in at the lowest cost just shy of $50 for the metabolism test. And you can save up to 30% with the subscription option, too.

My Toolbox Genomics is in a higher price range, but you do get quite a lot of information for that cost. It comes with fitness and diet information, plus loads of health insights that you usually have to pay extra for.

SelfDecode is probably one of the most expensive on this list. You have to pay a subscription fee to access reports, which costs nearly $300. If you don’t have existing DNA, you also need to buy a separate kit for $90. And the annual subscription is $97 a year, but you still have to pay for individual reports. They’re half price, but still, not free.

How does DNA affect weight and weight loss?

Some of the factors that affect your weight – including your appetite, fitness levels, and ability to lose weight and keep it off – are genetic. Being aware of these genetic predispositions may help you decide what type of weight management strategy is best suited to your goals.

With that said, biology is not destiny, and your genes are only part of the picture. Factors such as your eating habits, level of physical activity, and age also play a huge role in your weight. When you’re looking for an effective weight management strategy, you should take all of these factors into account – and consult with a doctor or nutritionist before embarking on any new diet program.

Can a DNA test help you lose weight?

A DNA test by itself can’t help you lose weight, but it can help you formulate a diet and weight loss plan that’s tailored to your specific genetic traits. This helps you make the most of your weight loss efforts and lets you manage your weight and fitness long term.

How accurate are DNA weight loss kits?

A DNA test looks at specific genetic markers in your DNA that have been shown to be associated with various physical and physiological traits. DNA tests are able to interpret these markers pretty accurately and tell you what they mean. While no DNA test is 100% accurate, the companies listed here use the latest science and accredited labs.

What sort of things do DNA weight loss kits measure?

DNA weight loss kits can explore factors such as the speed of your metabolism, your genetic likelihood of being overweight, whether you’re genetically predisposed to experience food cravings, and how quickly you may regain weight after weight loss. The reports can also give you insights into how your body responds to exercise and whether you could potentially have a vitamin deficiency.

Can a DNA test tell you what to eat?

No DNA test will give you a complete diet plan. But, depending on the test you take, your results may include recommendations for foods that meet the nutritional needs of your genes. These foods might be recommended based on what your body responds to best for weight loss, or what your body needs based on deficiencies. A test like LivingDNA can tell you exactly which foods to include in your diet, and which ones to drop out.

Does insurance cover the cost of DNA weight loss kits?

Insurance does not typically cover the cost of DNA weight loss test kits.  That said, you should get in touch with your insurance provider to fully understand your options.

What is the best DNA weight loss kit?

There are many DNA tests available to facilitate weight loss. The one that works best for you will depend on your personal preferences and goals. All of the tests on this list meet our high expectations for accuracy, thoroughness, and actionable insight.

Our top choice overall though, has to be Living DNA. It gives you the most comprehensive results, with a detailed look at which foods to include to help with weight loss, what to avoid, where you have deficiencies, and how your body metabolizes certain foods.
