Skip the Weight-Loss Guesswork: At-Home DNA Test Shows if GLP-1s Will Work for You
It could save you from wasting thousands on meds that might not be a good fit
Key Takeaways
- Obesity is a complex disease caused by different factors and requires different treatments.
- A test can determine which genetic types contribute to your weight gain and if GLP-1s help.
- The results may help patients avoid spending thousands on ineffective medications.
Imagine spending thousands of dollars on weight-loss medication—only to discover months later that it doesn’t work for your body. Frustrating, right? Now, for the first time, a test based on cutting-edge Mayo Clinic research can predict if your unique body will respond favorably to GLP-1 drugs. And it could change the weight-loss game forever, helping people save precious time and money on their wellness journey. Here’s everything you need to know about GLP-1 testing, including insight from doctors who use this tool with patients and a testimonial from one grateful user.
How does this GLP-1 test actually work?
Mayo Clinic researchers developed this DNA-based obesity test to identify genetic weight-loss types. Since 2023, only specialty obesity clinics could offer the test. But now, Phenomix Sciences offers it directly to consumers through a simple mail-in cheek-swab kit.
The test is based on groundbreaking science that shows people’s weight-related tendencies fall into four distinct categories or phenotypes—some that respond well to GLP-1 treatment and others that don’t. It’s the only consumer test on the market that identifies these four genetic types. The thinking: Before shelling out cash on weight-loss drugs, this GLP-1 test helps you and your doctor determine whether they’ll actually work for your system.

How to get the GLP-1 test for yourself
Step 1: Visit myphenometest.com and complete a short questionnaire to confirm the test is a good fit. If so, you can make a one-time payment for the MyPhenome test. It costs $299 and isn’t currently covered by insurance, but the results could help you save thousands on ineffective weight-loss drugs down the road.
Step 2: A kit will be mailed to your home. Use it to collect a painless cell sample with a cheek swab, then send the sample back in the provided prepaid mailer.
Step 3: Receive a personalized MyPhenome report within about three weeks through a secure patient portal. It reveals which of the four genetic types may be driving your weight gain—plus specific treatment recommendations matched to your unique biology.
Step 4: Share your results with your healthcare provider to inform future weight-loss guidance and treatment decisions.
What your results will reveal about your body
Based on genetic-type science, everyone either falls into one of these four phenotypes. You may be a:
Hungry Gut type
People in this genetic group tend to have fast gastric emptying, so they don’t sense the normal fullness cues that people feel as their stomach fills up. As a result, they often keep eating. GLP-1 receptor agonist medications often work well for people with this genetic type.
Hungry Brain type
People in this group always feel hungry because their body sends stronger hunger signals. So they need to eat more calories than their peers to reach maximum satisfaction. Some medications such as Qsymia (phentermine-topiramate) can help here more than GLP-1s.
Emotional Hunger type
Individuals in this group tend to overeat in response to emotional triggers such as stress, anxiety or depression. Often, the pleasure and reward centers in their brain respond intensely to sugar in processed foods, creating powerful cravings. Cognitive therapy and medications that include an antidepressant effect such as Contrave (naltrexone/bupropion) can help here the most.
Slow Burner type
People in this group often show characteristics of multiple types combined with a genetically slower metabolic rate, meaning they don’t burn calories as quickly as others. More research is needed to know what works best, but preliminary data suggests resistance training to build muscle may be most powerful here.
Why this test could be a game-changer
Experts now recognize that obesity is a complex disease with multiple causes, and what works for one person may not work for another. A study in the journal Obesity shows that phenotype-guided weight-loss treatments are twice as effective as traditional one-size-fits-all approaches.
Plus recent research from the Journal of the Endocrine Society finds that as many as 30 percent of GLP-1 medication users won’t succeed at achieving meaningful weight loss. That frustration means wasted money and time that could have been spent on more targeted approaches.
Mark Bagnall, CEO of Phenomix Sciences, the maker of the test, says, “GLP-1s have transformed obesity treatment, but they’re not the only option, nor are they the right option for every patient.”
How this GLP-1 test helped Jessica
Want to see how this works in real life? Minnesota mom Jessica Layeux, 52, knows the frustration of spending months and thousands of dollars on a GLP-1 that didn’t work. She was taking Zepbound. “But I wasn’t losing weight,” she recalls. “My doctor then recommended the MyPhenome test, which showed I had characteristics of both ‘hungry brain’ and ‘hungry gut.’ Based on those results, my treatment plan was adjusted.” She tried phentermine, a completely different class of medication that works on suppressing appetite and costs much less than GLP-1s.
That genetic insight proved priceless. “For the first time, I felt like I understood why I was struggling. Within a month of adjusting my treatment, I lost 20 pounds.” She raves, “Personalized obesity care helped me find an approach that finally worked for me.”
What medical experts say about GLP-1 testing
“MyPhenome is a valuable tool in my practice,” says Natalie Ikeman, PA-C, president of the Minnesota Obesity Society and an advisor for Phenomix. “It helps us better understand the genetic drivers behind each patient’s condition.”
As awareness of GLP-1 medications has grown, their use has skyrocketed in recent months. “With increased prescribing, I’ve also noticed a tremendous variability in patients’ response both initially at the lowest dose and over time with slow and continued dose escalation,” reveals obesity specialist Melina Jampolis, MD, who spent a decade studying the connection between genetics and nutrition. After seeing the research, she is now convinced of the vital role genes play in weight loss and uses this test with patients.
“It explained why some patients essentially stopped responding after four to six months despite achieving the maximum dose,” Dr. Jampolis says. “My patients felt very frustrated and disappointed when their response to the medications stopped. They are very relieved and happy to know that they were not doing anything wrong, their bodies were just genetically different.”
And good news if the test indicates that GLP-1s aren’t ideal for your body: With the test’s insights, your doctor can help guide you to different treatment options that may work better for your type.
The bottom line
“I now encourage all of my patients who have a considerable amount of weight to lose to undergo this testing, so we don’t waste time or money on GLP-1 medications or continued dose escalation that is likely doomed to stop working after 6 months,” Dr. Jampolis says. Remember, learning how your unique genes affect your metabolism can increase your chances of lasting weight-loss success.
