The Diet Your DNA Was Built For — ILSA Health Nutrition DNA Test

Nutrition DNA · 43 Genetic Traits

The food your body was built for is written in your DNA.

Why does keto transform one body and quietly break another? Why does Mediterranean cure one person's fatigue and do nothing for the next? Your genome already knows the answer.

Why most diets fail

It isn't your willpower. It's that nobody asked your genes.

Two people. Same diet. One transforms. One stalls. The standard explanation is discipline. The actual explanation is biology — and yours is finally written down where you can read it.

Two people, same calorie deficit. One loses 30 lbs. One loses two. The variable isn't effort — it's genetic response to specific macronutrients.

68% of adults are lactose intolerant. 25% metabolize caffeine so slowly it disrupts sleep for eight hours. Most never know.

Mediterranean, low-carb, higher-protein — the right diet for you depends on your DNA. Choosing wrong wastes years.

Your Macronutrient Architecture

Do you lose weight on fewer carbs — or on fewer fats?

Variants of the APOA2, FTO, and PPARG genes split human metabolism into two macronutrient architectures. The right diet for one is the wrong diet for the other. Most people are guessing — and losing years to the wrong half.

Body Comp Response

The carb-sensitive body.

Slower glucose clearance. Better adapted to fewer carbs.

Carb-sensitive genotypes (APOA2 CC variants, FTO risk alleles, certain PPARG variants) tend to gain weight more easily on high-carbohydrate diets and lose weight more efficiently on lower-carb, higher-fat, higher-protein patterns. Mediterranean and ketogenic protocols often work dramatically here. Long term, refined carbs disrupt energy, sleep, and body composition more than they do in the fat-sensitive genotype.

The Nutrition Blueprint

43 genetic traits. Four categories. The complete picture of how your body uses food.

Every dot is one trait we decode. Diet response, food reactions, vitamins and minerals, and eating behaviors — together they form the most complete map of your nutritional genome that science can currently offer.

All 43 traits

Your complete nutritional genome

Four categories. Forty-three traits. One DNA sample. Every dimension of how your body processes, reacts to, and benefits from food — decoded once and yours forever.

What you'll learn

Six revelations hiding in your nutritional genome.

Hover (or tap) to flip each card. These are real examples of the kind of insight your report will deliver — built from peer-reviewed nutrigenomics research.

Should you eat fewer carbs or fewer fats?

Hover to reveal →

Macronutrient Response (APOA2)

One of the most studied genes in nutrigenomics. APOA2 CC carriers tend to gain weight more easily on high-saturated-fat diets. TT carriers respond better to Mediterranean and lower-fat patterns. The right macronutrient ratio for you is genetic — not trendy.

Gene · APOA2 -265T>C

Can your body actually digest dairy?

Hover to reveal →

Lactose Tolerance (LCT)

Your DNA reveals whether you produce lactase into adulthood — or whether every glass of milk is quietly inflaming your gut, your skin, and your sleep. 68% of adults worldwide are intolerant. Most don't know until they see it on a report.

Gene · MCM6 / LCT-13910

Why does coffee keep you up past midnight?

Hover to reveal →

Caffeine Metabolism (CYP1A2)

Slow metabolizers feel one espresso for eight hours and rarely know why their sleep is broken. Fast metabolizers can finish dinner with a double. Your DNA places you on this spectrum — exactly. After this report, you'll know when to stop drinking it.

Gene · CYP1A2

Is gluten an actual problem — or a trend?

Hover to reveal →

Gluten Sensitivity Risk (HLA-DQ)

We screen for the genetic markers associated with celiac and non-celiac gluten sensitivity. For some, removing gluten changes everything — energy, gut, skin, sleep. For others, it changes nothing. Your DNA settles the debate.

Gene · HLA-DQ2 / HLA-DQ8

Why are you tired even when you eat well?

Hover to reveal →

Vitamin & Folate Absorption (MTHFR)

You can eat the perfect diet and still be deficient — because your genes determine how well you absorb and convert key vitamins. We map 15 essential vitamins and minerals so supplementation finally makes sense and stops being a guess.

Genes · VDR · GC · MTHFR · FUT2

Why is your hunger so loud?

Hover to reveal →

Satiety & Hunger Signaling (FTO)

The "fat mass and obesity-associated" gene shapes how strongly your body signals hunger and how quickly satiety registers. Some genomes get satisfied easily. Others fight constant hunger noise. Knowing this isn't a sentence — it's a strategy to design your day around.

Who It's For

If you've ever wondered why nothing works for you, this is the test.

The Nutrition DNA test is recommended for weight loss and nutrition planning. It's especially valuable for these four people.

The person who's tried everything

Keto. Whole30. Intermittent fasting. Calorie counting. Each one worked for someone — just not you. Your DNA tells you why, and what to try next instead of the next trending protocol.

The person on a GLP-1 journey

If you're on Semaglutide, Tirzepatide, or any weight-loss protocol, knowing your nutritional genetics multiplies the results — and tells you exactly how to maintain them when you taper off.

The person with unexplained symptoms

Bloating. Brain fog. Fatigue. Inflammation. Sleep that's never quite right. The answer is often a food your body wasn't built for — and you've been eating it for years without knowing.

The person who wants to stop guessing

You're done guessing whether you should drink coffee, eat dairy, fast in the morning, or count carbs. Your genome already knows. We just hand you the manual it was running on the whole time.

Questions, Answered

What you're probably wondering.

Will this test diagnose food allergies?

No — and that's an important distinction. A food allergy test measures your immune system's response. This is a DNA test that reveals your genetic predispositions: how your body processes lactose, gluten, caffeine, alcohol, sugars, fats, and which diet patterns your genome favors. It's powerful nutritional intelligence, but it isn't an allergy test. If you suspect a true allergy, see your physician.

How accurate is the lab work?

The testing is performed in a CAP/CLIA-accredited laboratory with greater than 99% accuracy. Every interpretation in your report is grounded in peer-reviewed nutrigenomics research. Your DNA and personal data are kept secure and HIPAA-protected at every step.

Do I need to take this test more than once?

No. Your DNA does not change. One test gives you a report that is yours, forever. As nutritional science evolves, the interpretations may be updated — but your underlying genetic data is a one-time gift to yourself.

Can I take this on a GLP-1 medication?

Yes — and many people do. GLP-1s control appetite and accelerate fat loss; nutrition genetics tells you which foods to eat so the weight you lose is fat (not muscle), and how to maintain the results after you taper. The answers are genuinely different for different genomes.

How long until I get my results?

Approximately 3–4 weeks from the moment the lab receives your sample. You'll receive your full personalized report by email and through your secure online dashboard. Tracking is provided at every stage.

Is the sample collection complicated?

No. It's a simple cheek swab you do at home in about two minutes. No lab visit. No blood draw. No appointment. The kit includes clear instructions and a prepaid return mailer.

Can I share the results with my doctor or dietitian?

Yes — and we encourage it. The report is designed to be a conversation starter with your physician, dietitian, or wellness practitioner. It is not a replacement for medical advice, but it gives your provider a layer of personalization they don't normally have access to.

Where do you not ship?

Due to state regulations on direct-to-consumer genetic testing, we currently do not ship to New York, Pennsylvania, Rhode Island, or Maryland. Anywhere else in the United States is fine.

Is my DNA data safe?

Yes. The lab is CAP/CLIA accredited and your data is stored in a HIPAA-compliant system. We do not sell or share your genetic data. You are always the owner.

The Last Word

Stop guessing what your body wants. Ask it.

One cheek swab. Forty-three answers. A lifetime of clarity about the food your body was built for. This is the test we wish we'd taken a decade ago.
