A whole-food reference
The clean ketogenic plate — built for metabolic health, not the scale.
Ketosis is the starting point, not the goal. In a well-formulated ketogenic diet it is nutrient density, food variety, and the diversity of the fats that do the real work. This page maps what to eat, why it matters, and what to measure — with fat quality treated as the centrepiece it deserves to be.
Whole foods, not "keto products"
Fat variety over fat volume
Judged by labs and how you feel
Who this is for
This describes a general whole-food ketogenic pattern for metabolic health — education, not medical advice, and not a PKD diet. Kidney disease carries its own requirements for protein, oxalate, phosphorus and potassium that this reference does not address; for that, see the Ren-Nu program and work with a renal dietitian. Anyone with a clinical condition, on medication, or pregnant should personalize this with their physician first.
01 — Ground rules
Six principles that make keto clean
These separate a nutrient-dense therapeutic pattern from "dirty keto." Everything downstream follows from them.
Fat quality over quantity
Draw fats from many real sources. You do not need to flood food with oil to be in ketosis.
Adequate, not maximal, protein
Enough to preserve lean mass. Protein supports satiety and muscle without breaking ketosis at sane intakes.
Fill the plate with plants
Non-starchy vegetables bring fiber, potassium, magnesium and polyphenols. Volume and color both matter.
Mind electrolytes
As insulin falls the kidneys shed sodium and water. Sodium, potassium and magnesium become daily priorities.
Track health, not weight
Energy, sleep, cognition and lab markers tell you far more than the number on the scale.
02 — The shape of the diet
Rough proportions, held loosely
Individual carbohydrate tolerance and protein needs vary. Treat these as starting ranges to personalize, not macros to obsess over.
Carbohydrate
keep low
~20–50 g net per day. Almost entirely from non-starchy vegetables, nuts, seeds and a little berry — never refined starch or sugar.
Protein
adequate
~1.2–2.0 g per kg body weight. Enough to protect muscle and drive satiety. Higher within the range if you are active or older.
Fat
to satiety
Fills the remaining energy. Let appetite set the amount — and let variety set the quality. That is what the next section is about.
03 — Fat is not one ingredient
The fatty-acid spectrum
"Eat more fat" is meaningless without asking which fats. Each class plays a different metabolic role. A clean ketogenic diet spreads its fat across all of them — heavy on monounsaturated and marine omega-3, moderate on saturated, and clear of industrial oils.
The single most useful lever is the omega-6 to omega-3 ratio. Whole-food omega-6 is fine; the problem is refined seed oils that push the ratio high and crowd out the omega-3 that resolves inflammation. Favor oleic-rich monounsaturated fat as the backbone, actively seek marine EPA and DHA, and skip added seed oils entirely.
Monounsaturated
BackboneMUFA · oleic acid · C18:1 ω-9
Stable, cardioprotective, anti-inflammatory. The fat your diet should lean on most heavily for cooking and dressing.
SourcesExtra-virgin olive oil, avocado and avocado oil, macadamia, hazelnut, olives.
Omega-3, marine
Seek outPUFA · EPA C20:5 · DHA C22:6
Long-chain, pre-formed and scarce in the modern diet. Central to membrane function and to resolving inflammation. Prioritize these deliberately.
SourcesSalmon, sardines, mackerel, anchovies, herring, roe, oysters.
Omega-3, plant
SupportivePUFA · ALA · C18:3 ω-3
Useful, but conversion to EPA and DHA is limited — treat it as a supplement to marine sources, not a replacement.
SourcesFlaxseed, chia, walnut, hemp seed.
Omega-6
BalancePUFA · linoleic · C18:2 ω-6
Essential and everywhere — the goal is not zero, it is balance. Get it from whole foods and stop adding it through refined oils.
SourcesNuts, seeds, poultry, eggs — whole-food only.
Saturated
ModerateSFA · e.g. stearic C18:0
Fine within a whole-food pattern and stable for heat — but not the centrepiece. Keep it in proportion, and watch ApoB if you are a hyper-responder.
SourcesButter and ghee, quality animal fat, full-fat dairy, coconut.
MCTs
Optional leverC8 caprylic · C10 capric
Rapidly ketogenic — a convenient tool for raising ketones. Easy to overdo; introduce slowly to avoid GI upset.
SourcesCoconut oil, MCT oil.
See this spectrum in your own meals
Every recipe in the kitchen planner carries a fat-quality bar using these same six colors, so you can see at a glance how a dish — or a whole week — distributes its fat.
04 — Build from variety
The whole-food building blocks
Variety is how you cover the micronutrient map and diversify fats at the same time. Rotate widely within each group rather than eating the same three foods on repeat.
Fatty fish & seafood
Salmon, sardines, mackerel, anchovies, herring, oysters, mussels, shrimp.
Brings — EPA and DHA, iodine, selenium, zinc, B12, vitamin D.
Pastured eggs & poultry
Whole eggs, chicken thighs, duck, turkey — skin and yolk included.
Brings — choline, complete protein, lutein, B vitamins.
Quality meats & organs
Grass-fed beef and lamb, pork, and liver — small, weekly, a nutrient powerhouse.
Brings — heme iron, B12, zinc, retinol, CoQ10.
Non-starchy vegetables
Leafy greens, broccoli, cauliflower, cabbage, Brussels sprouts, zucchini, asparagus, peppers, mushrooms. Eat the rainbow.
Brings — fiber, potassium, magnesium, folate, vitamin K, sulforaphane, polyphenols.
Avocado & olives
Whole avocado, olives, and their cold-pressed oils.
Brings — monounsaturated fat, potassium, fiber, vitamin E.
Nuts & seeds
Macadamia, walnut, pecan, almond, hazelnut, pumpkin, hemp, chia, flax. One Brazil nut covers selenium. Mind portions.
Brings — magnesium, fatty-acid diversity, fiber, vitamin E.
Full-fat dairy (if tolerated)
Aged cheese, plain kefir and yogurt, butter and ghee, cream.
Brings — calcium, vitamin K2, CLA, live cultures.
Fermented vegetables
Sauerkraut, kimchi, and other lacto-fermented, unpasteurized vegetables.
Brings — live cultures, fiber, vitamin K2, gut support.
Cold-pressed oils
Extra-virgin olive oil (dress liberally), avocado oil, coconut oil. Cook gently; finish raw.
Brings — monounsaturated fat, polyphenols, vitamin E, heat-stable fats.
Low-sugar fruit
Raspberries, blackberries, strawberries, a few blueberries; lemon and lime for acid.
Brings — polyphenols, vitamin C, fiber, low glycemic load.
Herbs, spices & aromatics
Garlic, ginger, turmeric, rosemary, parsley, cilantro, chili.
Brings — polyphenols, phytonutrients, flavor at zero carb cost.
Mineral support
Sea salt to taste, mineral water, bone broth — the everyday electrolyte base.
Brings — sodium, potassium, magnesium, collagen.
05 — Do not let these slip
Micronutrients & electrolytes to watch
A few nutrients need active attention — either because low insulin changes how the body handles them, or because they are easy to under-eat. The highlighted tiles are the ones people most often run short on.
Electrolytes The most common reason keto feels bad early on is a shortfall here — not the diet itself.
Sodium
Liberalize it. Sea salt, broth, salted foods — the fix for "keto flu."
Potassium
Leafy greens, avocado, mushrooms, salmon.
Magnesium
Greens, seeds, nuts, dark chocolate; often worth supplementing.
Calcium
Dairy, leafy greens, sardine bones.
Vitamins & trace Cover these through the food groups above.
Vitamin D
Fatty fish, sunlight, supplement as needed.
Vitamin K2
Fermented foods, aged cheese, egg yolk.
Choline
Egg yolk, liver — key for the liver itself.
Iodine & selenium
Seafood, seaweed, one Brazil nut a day.
Zinc
Oysters, red meat, pumpkin seeds.
Vitamin A
Liver, egg yolk, butter — the retinol form.
Vitamin E
Nuts, seeds, olive oil, avocado.
B12 & folate
Animal foods; folate from leafy greens.
06 — The line to hold
Favor generously · minimize deliberately
Favor
- Extra-virgin olive oil — your default fat, used raw and liberally
- Marine omega-3 — oily fish two to three times a week, minimum
- A wide rotation of non-starchy vegetables — color and volume
- Whole eggs, avocado, olives, nuts and seeds
- Fermented foods — for the gut and vitamin K2
- Herbs, spices, and salt to taste
Minimize
- Refined seed and "vegetable" oils — soybean, corn, canola, cottonseed, safflower
- Trans and partially hydrogenated fats — and re-used deep-fry oil
- Packaged "keto" snacks and bars — dirty keto in disguise
- Added sugars and refined starch — the obvious exclusions
- Cured meats loaded with additives — choose clean versions
- Sugar alcohols in excess — a GI cost, and they keep the sweet habit alive
07 — Measure what matters
Track health, not weight
If the goal is metabolic health, the scale is a poor instrument. These are the signals that actually reflect whether the diet is working. Revisit labs periodically with a clinician.
Insulin & glucose
Fasting insulin, glucose and HbA1c — the core of metabolic status.
Lipids
Triglycerides, HDL and the TG:HDL ratio; ApoB for particle burden.
Inflammation
hs-CRP, and an omega-3 index if available, to check fat balance directly.
Body composition
Waist circumference and lean mass beat scale weight — muscle and fat move differently.
Cardiovascular
Blood pressure and resting heart rate, tracked over weeks.
Lived signals
Steady energy, sleep quality, cognition, and hunger between meals.
Why not the scale? Daily weight swings on water and glycogen, hides muscle gain, and says nothing about inflammation or insulin. A better diet can improve every marker above while the scale barely moves — that is still success.
Common ways clean keto goes wrong
Bacon-and-cheese keto — heavy on saturated fat, empty of plants and marine omega-3.
Seed-oil frying — undoing good ingredients with the wrong cooking fat.
No vegetables, no fiber — starving the gut and missing potassium and magnesium.
Ignoring electrolytes — the real cause of fatigue, cramps and headaches early on.
Living on "keto" packaged food — ultra-processed, just low-carb.
Skipping oily fish — the omega-3 gap most diets never close.
