APOE Status
Your APOE type decides how your body handles saturated fat and cholesterol. Some versions shrug off butter and steak; others see LDL spike fast. Knowing yours ends the "is saturated fat evil?" debate—for you personally.
What this measures
How your DNA shapes apoe status.
APOE codes for apolipoprotein E — a transport protein that carries cholesterol and lipids through the bloodstream and into cells. Three common variants exist (E2, E3, E4), and their combinations produce six genotypes. Each variant binds LDL receptors differently, which changes how cholesterol moves and how the brain handles lipid metabolism over decades.
Carriers of the E3 variant — the most common — are associated with typical lipid handling and typical cognitive aging. E4 carriers are associated with higher LDL cholesterol on saturated-fat-heavy diets and an elevated lifetime risk of Alzheimer’s disease (the strongest known common genetic risk factor for late-onset Alzheimer’s). E2 carriers are associated with lower LDL but elevated triglycerides and a small risk of a rare lipid disorder.
The APOE–saturated-fat interaction is one of the best-studied gene-diet pairings in nutrition. E4 carriers see larger LDL responses to saturated fat than E3/E3. Aerobic exercise, sleep quality, and omega-3 intake all influence neuroinflammation pathways that are most relevant for E4 carriers. Mediterranean-style diets blunt the saturated-fat effect across variants.
Knowing your APOE status changes what "heart-healthy diet" actually means for you. The generic recommendation works fine for most. For E4 carriers, the diet is the same direction with more conviction — and the cognitive-health angle becomes part of the conversation rather than a separate worry.
APOE Status is one specific finding in this system. Your Genomic Lifestyle Optimization Report shows where your variants place you on the macronutrients and metabolic optimization spectrum — and what you can do about it.
In your report
Where APOE Status lives inside your Genomic Lifestyle Optimization Report.
APOE Status renders as a dark-background card with a color marker calibrated to your specific variants. The card opens with the gene mechanism, shows your result at a glance via that marker, and closes with a practical, mechanism-led recommendation — what to eat, what to time, what cofactors to support.

In context
Saturated Fats: the 2-insight cluster.
APOE Status is one finding in a tightly-related cluster. Mosaic sequences the other 1 alongside it so you see the whole biology — not an isolated data point.
Questions people ask
About APOE Status.
- How does my DNA influence apoe status?
- The macro ratio your biology performs best with is encoded in genes that govern carbohydrate sensitivity (PPARG, TCF7L2), saturated-fat response (APOE, APOA2), protein utilization (FTO, ACE), and fish-oil conversion (FADS1/2). One person's optimal protocol is another person's metabolic friction.
- What kind of test do I need to see my APOE Status result?
- Whole-genome sequencing at 30× clinical depth. Consumer SNP-chip tests like 23andMe or AncestryDNA only read ~0.02% of your DNA and miss most of the variants this analysis needs. Mosaic reads all 3 billion base pairs and produces the full 108-insight report.
- How is APOE Status different from clinical lab testing?
- Clinical labs measure downstream biomarkers — blood levels, hormone values, metabolic byproducts — at a single point in time. Genomic insights like APOE Status reveal the underlying variant that shapes the biology, which is constant for life. The two are complementary: labs show the current snapshot; genomics shows the long-term tendency and where lifestyle leverage is highest.

Basal Metabolic Rate
The number of calories you burn lying completely still varies up to 300–400 kcal/day between people of the same size. Knowing your baseline stops the frustration of "why am I not losing weight on 1,500 calories?"

Fiber Benefit
Some people drop cholesterol and feel full on high-fiber meals. Others barely notice. This tells you whether loading up on oats and vegetables is a game-changer or just extra chewing.

Ideal Carbohydrate Intake
Your genes determine whether you thrive on 45–65% carbs or feel better under 30%. Matching intake to your insulin sensitivity and carbohydrate metabolism keeps energy stable and weight easier to manage—without forcing a diet philosophy that doesn't fit your biology.

Ideal Protein Intake Amount
Protein needs range from 0.8 g/kg up to 2.2 g/kg for the same goals. Knowing your sweet spot prevents under-eating (slow recovery, muscle loss) or over-eating (expensive urine, stressed kidneys for no reason).

Ideal Total Fat Intake Amount
Some metabolisms run beautifully on 35–40% fat; others stall above 25%. Your genes wrote the manual—now you can follow it instead of borrowing someone else's.
