Recommendations

  • ▸15 g omega-6 / 1.5 g omega-3 = 10:1 — Elevated — two fish servings fix most
  • ▸Fastest fixes: 2 weekly salmon servings (+1-2 g EPA+DHA), 1 tbsp ground flax daily, olive oil for everyday cooking
  • ▸Halving fryer foods plus adding fish usually moves 10:1 toward 4:1 within a month
  • ▸Absolute EPA+DHA (250-500 mg) matters more than the ratio alone — hit that first

O3Omega-3gALA + EPA/DHA
RatioBalance:1O6 over O3
GoalTarget:14 or lower

Explanation

Typical 10-20:1 diets rebalance in weeks with fish and olive-first cooking.

Derivation

Divide the pools; move fish up and fryer load down.

Step-by-Step Calculation

Follow each step to understand how the result is calculated from your inputs.

Step 1

Total the omega-6.

Oils, nuts, fried foods
O6:15 g
Intermediate: Ubiquitous intake
Result: O6 known
Step 2

Total the omega-3.

ALA plus EPA/DHA
O3:1.5 g
Intermediate: Both paths count
Result: O3 known
Step 3

Divide into the ratio.

Ratio = O6 / O3
Ratio:10:1
Intermediate: One balance number
Result: Divided
Step 4

Judge against 4:1.

On target, elevated, high
Verdict:Elevated — two fish servings fix most
Intermediate: Goal band
Result: Judged
Step 5

Move both levers.

Add fish, trim fryer load
Moves:2 fish + olive-first
Intermediate: Weeks, not days
Result: Moved
Step 6

Protect absolutes.

EPA+DHA 250-500 mg first
Rule:absolutes beat ratio
Intermediate: Halving fryer foods plus adding fish usually moves 10:1 toward 4:1 within a month
Result: 15 g omega-6 / 1.5 g omega-3 = 10:1 — Elevated — two fish servings fix most
Final Answer
10:1

Worked Examples

See how the calculator works with different scenarios.

Scenario

15 g omega-6, 1.5 g omega-3.

Inputs

O6:15 g
O3:1.5 g

Calculation

15/1.5 = 10:1 — elevated.

Result

Two fish servings fix most 10:1 diets

Interpretation

Add 1-2 g EPA+DHA weekly and swap fryer oil for olive.

Understanding Your Result

Your Result: Omega ratio: 10:1

Typical range: AMDR 20-35%; saturated under 10%; MUFA 15-20%; PUFA 5-10%; ALA 1.6/1.1 g; EPA+DHA 250-500 mg.

What This Means

Divide omega-6 grams by omega-3 grams — see your ratio against the 4:1 goal and get moves that fix the balance.

Why It Matters

Fat balance in a single number.

Professional Interpretation

Lead every fat budget with unsaturated sources and audit the saturated ceiling — mix decides lipids, totals decide weight.

Swap beats cut

Replacing saturated with MUFA/PUFA improves lipids more than cutting total fat.

Absolutes beat ratios

Hit 250-500 mg EPA+DHA first; the omega ratio follows.

Recommendations

  • •Cook olive-first, dress with vinaigrette
  • •Eat fatty fish twice weekly
  • •Log cooking oils every time
  • •Keep saturated under 10% with swaps
  • •Hold fat above 0.5 g/kg on cuts

Educational Content

Introduction

Divide omega-6 grams by omega-3 grams — see your ratio against the 4:1 goal and get moves that fix the balance.

Concept Explanation

Price fat from calories and share with 9 kcal/g, cap saturated fat at 10%, and verify omega-3 and the omega balance.

Applications

▸Setting daily fat for any phase
▸Auditing saturated fat against the ceiling
▸Balancing MUFA and PUFA sources
▸Checking EPA+DHA and ALA intake
▸Fixing omega-6 to omega-3 ratios
▸Choosing cooking fats by job

Benefits

  • •Gram targets with cooking-fat equivalents
  • •Saturated-fat ceiling in grams
  • •MUFA/PUFA balance guide
  • •Omega-3 gap with fish servings
  • •Hormone-safe floors built in

Limitations

  • •Averages absorption and food variance
  • •Blood lipids need labs, not math
  • •Single-day snapshot; patterns decide
  • •Supplement doses estimated, not verified

Best Practices

  • •Cook with olive oil, dress with vinaigrette
  • •Eat fatty fish twice weekly
  • •Snack on nuts, not pastries
  • •Log cooking oils every time
  • •Keep saturated under 10% with swaps

Common Misconceptions

Myth: Eating fat makes you fat.
Truth: Excess calories do; adequate fat improves fullness, hormones, and vitamin uptake.
Myth: All saturated fat is poison.
Truth: Dose decides: under 10% within an unsaturated-first pattern is the consistent guidance.
Myth: Seed oils are toxic.
Truth: Trials link linoleic acid to lower LDL and diabetes risk; fried-food excess is the real issue.

Practical Tips

  • •Make unsaturated fats the default
  • •Measure oils for two weeks to calibrate
  • •Put fish on the menu twice weekly
  • •Swap, do not just cut, saturated fat
  • •Keep fat above 0.5 g/kg on cuts
  • •Pair fat with vegetables for vitamin uptake

Common Mistakes

Skipping cooking oils in logs
One tablespoon is 120 kcal; log every pour for two weeks.
Cutting all fat on a diet
Hold ~0.5-1 g/kg; cut carbs first and keep hormones intact.
Chasing ratio while missing EPA+DHA
Hit 250-500 mg EPA+DHA first; the ratio follows.
Coconut oil as health food
It is 90% saturated; use olive oil daily and coconut rarely.
Fat-free products over whole foods
Fat-free often adds sugar; prefer measured whole-food fats.

Assumptions

This calculator makes the following assumptions to provide estimates:

9 kcal/g: Fat energy density for gram math.
10% ceiling: Saturated fat cap from dietary guidelines.
AMDR band: 20-35% of calories as the reference range.
AI omegas: ALA 1.6/1.1 g and LA 17/12 g adequate intakes.

Limitations

Be aware of these limitations when using this calculator:

Estimated, not measured: Blood work, not math, judges lipid outcomes.
Food variance: Cuts of meat and dishes vary widely.
Snapshot day: Weekly patterns matter more than one day.
Not medical advice: Lipid disorders need clinician guidance.

Frequently Asked Questions

Answers to common questions about this calculator.

What is a good omega ratio?
Around 4:1 or lower. Typical Western diets run 10–20:1 — high but fixable.
How do I lower my ratio?
Add 1–2 weekly fish servings or 1 g EPA+DHA, swap some seed oil for olive oil, add walnuts and flax.
Does the ratio beat absolute intake?
Both matter: hit 250–500 mg EPA+DHA first, then let the ratio confirm balance.
How much fat per day is healthy?
20–35% of calories (44–78 g on 2,000 kcal), with a practical floor near 0.5–1 g/kg to protect hormones.
How much saturated fat is too much?
Keep saturated fat under 10% of calories (under ~22 g on 2,000 kcal). Swap butter, palm, and fatty meats for olive oil, nuts, and fish.
What are omega-3s and how much do I need?
ALA 1.6 g/day (men) or 1.1 g (women), plus 250–500 mg EPA+DHA from fatty fish or supplements.
What is a healthy omega-6 to omega-3 ratio?
Around 4:1 or lower. Most Western diets run 10–20:1 — add fish, walnuts, flax, and cut seed-oil-heavy fried foods.
Does eating fat make you fat?
No. Excess calories do. Fat at 9 kcal/g is easy to overeat, but adequate fat improves fullness, hormones, and vitamin absorption.
Which fats are unsaturated?
Monounsaturated: olive oil, avocado, almonds, peanuts. Polyunsaturated: sunflower, soybean, walnuts, flax, fatty fish.
How accurate are these nutrition estimates?
Within about 10–15% when stats and activity are honest. Validate against 2–4 weeks of trend: stable weight confirms maintenance, steady drift corrects it.
Should I use current or goal weight?
Current weight. Equations describe the body you have. Re-run per 10–15 lbs of change as needs fall with size.
What activity level should I pick?
Price your real week: desk job with 3 lifts is light-moderate, not heavy. When between rungs, pick the lower one and let the scale confirm.
Do I need to hit macros exactly every day?
No. Weekly averages decide outcomes. Land within ~5–10 g of protein and ~10–15 g of carbs and fat most days.
Should macros differ on rest days?
Optional. Identical daily targets work well; a common refinement trims carbs on rest days while holding protein and fat.

Saturated fat
Solid-at-room-temp fat (butter, palm, fatty meat); keep under 10% of calories.
MUFA

ALA
Alpha-linolenic acid: plant omega-3 (flax, chia, walnuts); 1.6 g men, 1.1 g women.
EPA/DHA
Marine omega-3s in fatty fish; 250–500 mg/day supports heart and brain.
