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?"
What this measures
How your DNA shapes basal metabolic rate.
Basal metabolic rate is the energy your body burns at rest. UCP2 and UCP3 code for mitochondrial uncoupling proteins — the molecular switches that decide whether energy from food becomes ATP or escapes as heat. ADRB3 codes for a beta-3 adrenergic receptor that controls fat-cell metabolic activation.
Carriers of common UCP2/UCP3 reduced-activity variants are associated with somewhat lower basal energy expenditure — a "fuel-efficient" engine that burns fewer calories at rest. Carriers of the ADRB3 Trp64Arg variant are associated with reduced lipolytic response. The combination shapes how much energy a body burns just being alive.
Cold exposure activates brown adipose tissue and acutely raises uncoupling. Resistance training raises resting metabolic rate by adding metabolically active tissue. Adequate protein at meals raises thermogenesis 20–30% higher than equivalent calories from fat. Sleep deprivation drops BMR within days; chronic under-eating drops it further.
Two people the same height and weight don’t burn the same calories at rest — and the gap is real, not a story someone tells themselves. Which variants you carry decides whether default activity is enough or whether the math requires more deliberate inputs to stay where you want to be.
Basal Metabolic Rate 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

Basal Metabolic Rate 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.

Questions people ask
About Basal Metabolic Rate.
- How does my DNA influence basal metabolic rate?
- 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 Basal Metabolic Rate 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 Basal Metabolic Rate 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 Basal Metabolic Rate 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.

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.

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.

Monounsaturated Fat Response
Olive oil and avocado can dramatically lower inflammation and improve insulin sensitivity—but only in people with the responsive genotype. This decides whether "extra virgin everything" is worth the premium or just tasty calories.
