Do DNA Diets Actually Work? Find out now.

Do DNA Tests Actually Work?

According to the Human Genome Project, the human genome has between 20,000 to 25,000 genes. Also, the science of nutrigenomics is progressing every day.

The biggest problem with the articles that look down DNA diets is that they don’t explain the difference between basing a diet on a single gene and using a complex algorithm which factors in hundreds of genes.

However, single genes can still have a big impact. 

For example, one Harvard study found that people with a specific FTO gene variation lost a lot more weight on a higher-protein diet.

These types of studies are vital in helping us overcome the current one-size fits all diets that don’t look at us as individuals.


So the answer is yes, a diet plan based on DNA can certainly work, especially if it looks at a significant range of your genes instead of just a couple.

What does a DNA diet plan look like?

What a diet plan based on DNA looks like depends on who (or what, in the case of algorithms) created it.


A good DNA diet plan will not only tell you what you should and shouldn’t be eating, but why, and give you actionable advice on how to optimize your diet based on your genes.


Not all types of DNA diets do this.


For instance, if your caffeine sensitivity genes show that overall, you’re moderately sensitive to caffeine, a good DNA diet plan will tell you exactly how much is safe to consume: maybe two to four cups a day.


It will also give you a breakdown of all the genes that the algorithm has analysed to come to that conclusion.  We currently know of five genes that affect how your body deals with caffeine.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.

Caffeine sensitivity is affected in two basic ways:

First, you may metabolize caffeine more slowly, which increases your sensitivity to its effects.

Second, caffeine may lower your bone density, depending on your genetic variations.

At LifeDNA, we combine these two factors to determine how much caffeine you can safely consume in a day.

A good DNA diet plan will also give you the references to the scientific studies that your advice is based on.


What are the best DNA diet tests?

From the results, you need to learn how to optimize your wellness and quality of life. While getting the results you want may take some effort, putting the advice into practice should be easy.

Your results should be crystal-clear, simple, specific and actionable.

Because knowing that you should consume less caffeine, for instance, isn’t giving you the information you need to change your behavior. You also need to know why you need to cut your coffee intake (what could happen if you don’t), and exactly how many lattes you can get away with.

You should also look for reports that present their information in a clear, compelling and attractive way. You’ll be seeing and digesting a lot of complex data: looks count for a lot here.

Are DNA diet tests accurate?

DNA diet tests are very accurate at revealing the specific genes that you carry. The science behind the cheek swab tests is trusted by experts worldwide. There’s no question that they’re both reliable and accurate.

However, if your question is really ‘will my DNA diet test make me lose weight/feel healthier’, the answer isn’t so simple.

That’s because your health and wellness depends on so much more than just your genes. While your genes are a crucial and undeniable part, there’s a massive environmental component too. 

For instance, we know that the 100 trillion bacteria that make up your microbiome have a huge impact on your ability to tolerate gluten. 

So, your genes might say you should be able to digest bread without a problem, but if your gut bugs say different, you could feel better staying away from sandwiches. 

Are DNA diets the same as other weight loss diets?

No, DNA diets aren’t the same as other diets.

For a start, most DNA diets aren’t about losing weight: they’re about maximizing your health and longevity

Sure, some genes affect how easy or hard it is for you to lose weight, but that’s usually not the focus of a DNA diet.

Most weight loss diets focus on depriving yourself and being hungry. DNA diets focus on making the most out of your own individual body and metabolism to make losing weight a healthier and more pleasant experience, if that’s what you want to do.

Final Thoughts

DNA diets do work: we have the science to prove it.

Saying DNA diets don’t work is like saying that we can’t predict the weather because sometimes meteorologists get it wrong. 

We can’t base our conclusion about a whole area of science on one-off examples and small-scale studies.

DNA diets have the power to revolutionize your life, if you use them as one part of a toolkit that takes into account the rest of the factors that make and maintain health.

Your DNA isn’t your fate, but it can put you on a path to wellness and give you a map to help you get to the summit.

Risks of Sharing DNA with Genetic Testing Sites

Risks of Sharing DNA with Genetic Testing Sites


Nowadays, many consumer DNA testing companies promise to reveal everything from personal traits to health predispositions to other secrets hidden in your DNA. 

There is nothing more sensitive than your genetic information, and uploading your raw data or taking a test entails sharing your personal genetic information with other DNA sites. 

It’s important to understand how your DNA data might be used by these companies, and how you can prevent your DNA information from being stolen, or shared with others without your consent.

Read on to learn more about the risks involved with uploading your genetic information using DNA sequencing tools.

How Law Enforcement May Get Access To Your Genetic Information

Consumer genetic databases, particularly the ones that offer free genetic testing, may be used by law enforcement for police investigations.

In 2018, GEDMatch, a free-to-use genetic service, gave law enforcement officials access to user records to help in the investigation of murders and sexual assaults, unless users opted out.

In the same year, FamilyTreeDNA made some modifications to its terms of service in order to allow law-enforcement use in cases of “violent crimes.”

Nowadays, it is suspected that some companies that offer DNA analysis for free might actually be run by law enforcement agencies, which means that your information might be easily accessible for solving criminal cases. 

However, it is important to take note that there are reputable companies that still take your privacy as their top priority, and have strict policies on how to protect your information.

23andMe and Ancestry, for example, have kept their ground in not releasing any customer data to law enforcement. 

LifeDNA, in particular, is one of the companies that value users’ privacy in relation to potential law enforcement requests. Please check out our Privacy Policy to learn more about how we protect your data.

While these reputable businesses choose to fight demands from law enforcement by using all available legal and administrative means, they may still be required by law to comply with a legitimate court order, subpoena, or search warrant for genetic or personal information.

Is Your DNA At Risk From Cyber Attacks?

Certain DNA testing websites do not have stringent security measures, making their system more susceptible to a data breach. 

In 2017, researchers at the University of Washington discovered indications of poor security practices utilized in many open-source DNA sequencing tools

The study identified known security flaws that could enable unauthorized parties to acquire control of computer systems, potentially letting them steal your personal information or even alter DNA results.

Some of the DNA test companies that had cases of security breach in the past include MyHeritage, GedMatch, and Veritas Genetics

There are people out there who would want to steal your data. That’s why it is important to know how these companies protect your DNA information against cybersecurity risks.


At LifeDNA, the safety of our users’ information is our top priority. Your DNA is encrypted, safe, and secure. 

We never had a data breach in our system, and we regularly check our security measures in order to keep DNA information protected at all times. 

Already taken a DNA test with 23andMe, Ancestry, or other genome sequencing tools? Upload your DNA and gain insights into your health and wellness. See LifeDNA plans here.

Do not let other people steal your DNA information.

Your DNA is the blueprint of your life, and we, at LifeDNA, stand by you in keeping your DNA safe and secure. 

We do recommend that you go for companies that you can trust and that can protect your data.
