Omega-6 Intake Needs
Some people handle high omega-6 (seed oils, processed foods) without inflammation; others convert it into pro-inflammatory compounds fast. This tells you how strict you need to be with cooking oils—and whether the vegetable oil debate applies to you.
What this measures
How your DNA shapes omega-6 intake needs.
The same FADS1/FADS2 enzymes that convert omega-3s also handle omega-6 conversion to its active forms. The two fatty acid families compete directly for these enzymes — which is why ratio matters as much as absolute intake. Carrier-specific variants set how efficiently each pathway runs.
Carriers of high-activity FADS1/FADS2 variants are associated with stronger conversion of dietary linoleic acid into arachidonic acid — and a higher inflammatory tone from the same omega-6 intake. Carriers of low-activity variants convert less and tend to tolerate higher omega-6 intake with less inflammatory penalty. Either pattern can be balanced; both respond to ratio adjustment.
Modern Western diets push omega-6 intake far above ancestral baselines, mostly from seed and vegetable oils (soybean, corn, sunflower). Reducing processed-food intake is the single most consequential omega-6 move. Pairing omega-6 with sufficient omega-3 buffers the inflammatory response. Whole-food omega-6 sources (nuts, eggs, poultry) behave differently from refined seed oils across all variant patterns.
"Omega-6 is inflammatory" is a half-truth that varies meaningfully across people. Which FADS variants you carry decides whether the priority is cutting omega-6 sources, increasing omega-3 to balance ratio, or simply switching the source profile from refined oils to whole foods.
Omega-6 Intake Needs 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: it renders as a dark card with a color marker calibrated to your variants, opening with the gene mechanism and closing with a practical, mechanism-led recommendation.

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.
Read insight →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?"
Read insight →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.
Read insight →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.
Read insight →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).
Read insight →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.
