Most articles on what to eat on keto are exhausting. They list a hundred foods to chase and a hundred to avoid, recommend products you've never heard of, and treat the whole thing like a puzzle that needs solving every time you walk into a kitchen.

It isn't. Keto is one of the simpler dietary frameworks to cook around once you understand the structure. Three components per plate. Familiar ingredients. The kind of food a thoughtful adult would cook for dinner without thinking about a diet at all.

This page is the three-rule version. No bulletproof coffee, no MCT oil, no exogenous ketones. Just food, the way it's supposed to be.

The three-rule plate

A keto plate has three components:

That's the structure. Every keto meal worth eating fits this shape. The variations are infinite — different proteins, different vegetables, different cooking methods, different cuisines — but the underlying plate is the same.

The book has an illustration called the Balanced Keto Plate (Figure 7.2) and a variation called the Plate Trio (Figure 7.3) showing this shape across breakfast, lunch, and dinner. The point of the illustrations is that once you've seen the structure twice, you can build any meal from it without referring to a recipe.

What's deliberately missing from this list is also worth naming. There's no carbohydrate component because keto means low carbohydrate; the vegetables provide enough. There's no "sweet" component because most sweet foods don't fit, and the few that do (a few berries with cream, occasionally) aren't a structural part of the plate. There's no snack component because the plate is meant to be substantial enough that snacks become unnecessary — more on that below.

Three rules. The rest is detail.

Protein: the anchor

The protein anchor is the most important and the most under-eaten component of most keto meals. People focus on cutting carbs, then focus on adding fat, and somehow forget that the protein is the part that makes a meal genuinely satisfying for six or seven hours.

The target is 30 to 50 grams of protein per meal, with the upper end for active adults, men, and anyone training. That's roughly the protein in a palm-sized piece of meat or fish, or four eggs, or a substantial portion of Greek yoghurt. Less than 30 grams per meal and you'll usually be hungry again within an hour or two; more than 50 grams is rarely necessary and harder to eat in one sitting.

The good sources, in roughly the order they show up on most plates:

Beef and lamb. Sirloin, ribeye, mince, brisket, lamb chops, lamb mince. The fat that comes with these meats is part of the meal, not something to trim off. Higher-welfare cuts are worth paying for when you can.

Chicken. Thighs (with skin) more than breasts (without). Roast whole birds when you can — the leftover meat does several meals' worth of work.

Fish, especially fatty fish. Salmon, mackerel, sardines, tuna, trout. Two or three servings of fatty fish a week supplies most of the omega-3 fatty acids that complement a keto diet. Tinned fish counts — tinned sardines and mackerel are some of the most nutritious and cheapest foods you can buy.

Eggs. Three or four eggs is a real meal, especially with vegetables on the side. Pasture-raised eggs from a good source taste different from supermarket cage eggs; once you've eaten the former for a few weeks the latter becomes obviously worse.

Cheese. Hard cheeses (cheddar, parmesan, manchego, gouda) are useful protein and fat sources. Soft cheeses (feta, goat, halloumi) work in salads and as components rather than mains. Most adults can eat cheese on keto; some people find dairy slows their progress and prefer to use it sparingly.

Greek yoghurt. Full-fat, plain. A serving is breakfast or a post-training meal. Don't buy the flavoured versions — they're usually sugar-led.

The single most common reason people stall on keto is under-eating protein. If you're losing energy, losing muscle definition, or constantly hungry, the first thing to check is whether you're hitting 30-50 grams per meal. Most people aren't.

Plants: not optional

There is a strange myth that keto means cutting out vegetables. It doesn't. Vegetables — specifically the non-starchy kinds — are the load-bearing component of most keto plates, providing fibre, volume, micronutrients, and most of the day's potassium and magnesium.

The right vegetables in roughly increasing order of importance on the plate:

Leafy greens. Spinach, kale, chard, rocket, watercress. Two generous handfuls per meal isn't unreasonable. Cooked in butter or olive oil, dressed with lemon and salt; or raw in a salad with a proper dressing.

Cruciferous vegetables. Broccoli, cauliflower, cabbage, Brussels sprouts. Roasted hard in a hot oven until the edges are deeply browned, not boiled to grey. These transform when cooked properly.

Courgette, asparagus, peppers, mushrooms. The reliable everyday keto vegetables. Easy to cook in batches and reheat.

Salad vegetables. Tomatoes, cucumber, radishes, fennel. A proper salad — leaves, several vegetables, a real dressing — is a meal on its own with the protein anchor added.

Garlic, onion, herbs. Don't forget these. They're what makes the food taste like food. A few cloves of garlic and a small onion in most savoury cooking; herbs by the bunch when they're fresh.

Frequency: every meal. Two or three handfuls of vegetables, cooked or raw, alongside the protein and fat. This is the part most keto blogs underweight. The plates online are typically half meat, a sprig of something green, and a slick of fat. The actual book's plates are much more vegetable-heavy than that — closer to half the plate.

The book's Adapt phase explicitly addresses people who reduce vegetables in the first weeks of keto and develop digestive issues, fatigue, or micronutrient deficiencies. The fix is to put the vegetables back. They're not a side dish; they're a primary component.

Fats: to satiety, not to a target

This is where most keto content gets loud and wrong. You don't need to chase fat percentages, pour butter into coffee, or eat fat for its own sake. Fat is the satisfying component of the plate. Add it until the meal is satisfying. Stop when satisfied.

The good sources:

Olive oil. Drizzled on salads, finished onto cooked vegetables, used for everyday cooking. Buy a decent extra-virgin for finishing and a cheaper olive or rapeseed oil for higher-heat cooking if you prefer.

Butter. Real butter, salted or unsalted. For cooking vegetables, finishing fish, scrambling eggs. The flavour matters; better butter is worth paying for.

Avocado. Half or a whole one, on or next to most meals. Reliable, filling, and one of the best potassium sources on keto.

The fat that came with the meat. Skin on the chicken, marbling in the beef, the rendered fat from cooking pork. Don't trim it off.

Fatty fish, eggs, hard cheese. All include their own fat. They count.

What you don't need: MCT oil, coconut oil added to coffee, "bulletproof" anything, exogenous ketones, mass-quantity nut butters, or any product that's marketed specifically as keto. The keto industry sells shortcuts that aren't necessary and aren't helpful. The book's position on this is direct: real food, real cooking, no shortcuts. This page takes the same position.

The right amount of fat per meal is the amount that makes the meal satisfying enough to last six or seven hours. Less than that and you'll be hungry early. More than that and you're eating fat for its own sake, which is neither necessary nor pleasant. Trust the satiety signal. The body knows.

What to leave off the plate

Honest about this. The list is short and unsurprising. Most people who've found their way to a keto article already know what isn't on the plate.

What surprises people the most when they switch to keto isn't what's off the list. It's how little they miss most of it after the first two weeks. The body stops asking for foods it's no longer dependent on.

Sample meals (no recipes)

To make the structure concrete, six plates. These aren't recipes — they're shapes. The point is to show how unremarkable a keto plate looks once you stop thinking of it as a diet.

Breakfast. Three eggs scrambled in butter, half an avocado, sautéed spinach with garlic, a generous pinch of salt.

Lunch. Pan-fried salmon, dressed mixed leaves, butter-roasted asparagus, olive oil and lemon over everything.

Lunch (alternative). A large salad — chicken thighs (cold from yesterday), feta, olives, cucumber, tomato, red onion — dressed with olive oil, lemon, and oregano.

Dinner. Slow-cooked lamb shoulder, roast cauliflower (hard, with spices), a large green salad, butter melted into the cauliflower at the end.

Dinner (alternative). Two pork chops, mushrooms cooked hard in their own juices, a generous serving of buttered green beans, a dollop of soured cream on the side.

Either meal. A whole roasted chicken with thyme and garlic, a tray of roasted Mediterranean vegetables (courgette, peppers, onion, aubergine), a green salad, plenty of olive oil over the vegetables.

None of these are unusual food. None of them require special ingredients. None of them take longer to cook than the meals they're replacing. This is what keto cooking actually looks like.

A note worth making: one of the book's authors is a working chef. The food in the book is built from a professional kitchen's understanding of what makes meals worth eating, not from a diet blogger's understanding of what fits a macro target. If the plates above sound like real cooking rather than diet food, that's because they are.

Snacks (the hard truth)

Most "keto snacks" are unnecessary.

If you're hungry between meals on keto, the issue is usually one of three things, in order of likelihood.

Your meals are too small. Particularly the protein. A meal that ends with you still slightly hungry is a meal that didn't have enough protein, fat, or both. The fix isn't snacks; it's larger meals.

You're under-salted or dehydrated. A lot of what feels like hunger in the first weeks of keto is actually mild dehydration plus low sodium. A glass of water with a quarter-teaspoon of salt resolves it in ten minutes for most people. The electrolytes article covers this in detail.

You're grazing out of habit. If you used to snack at 11am and 4pm, the body has learned to expect food at those times even when it doesn't biologically need it. Hold the line for two weeks; the habit fades.

The two-meal rhythm — two real meals, eight hours apart, nothing in between — makes snacks structurally unnecessary. Once the rhythm settles, snacks lose their purpose.

If you genuinely need something between meals during travel or unusual schedules, the options are short and unsurprising. A small handful of olives. A piece of hard cheese. A few macadamia or pecan nuts. Tinned sardines. The point isn't to find clever keto snacks; the point is to need them rarely.

The shopping list

A compact one-glance version of everything above. This is a week's worth of basics for most adults, not a complete pantry.

Proteins (rotate, don't buy all):

Vegetables:

Fats:

That's enough to cook from for a week without referring to a recipe. The book has more detailed shopping guides and weekly meal plans across the Five-Phase Journey.

A closing word

What to eat on keto turns out to be much less complicated than the internet suggests. Real food. Three components per plate. Familiar ingredients. Cooked properly.

The book this page sits alongside contains the full meal frameworks across all five phases — Reset, Adapt, Optimise, Integrate, and Thrive — with the meal plans, the cooking guidance, and the practical adjustments for real life. Keto Dive on Amazon.

If you want the one-page reference first — the Reset Card lives at the bottom of ketodive.life and includes the plate structure on a printable sheet.

A cookbook from the same authors is in development, focused specifically on the cooking side — Krzysztof's professional kitchen approach to keto food that's worth eating. More on that when it arrives.

In the meantime: cook real food, build the plate around protein and plants and fat, and trust that the rest takes care of itself.
