The Basics of Low-Carb Eating
Low-carb eating rests on one decision: remove fast sugar from the day and give the freed-up space to fats, protein, and vegetables. A maximum of 50–70 grams of carbohydrates remains per day, food becomes filling, and there are two or three meals, with no snacks between them.

What you'll find here
This section answers the questions that come up before your first trip to the store. How many carbohydrates fit into a day and how to count them. Where to get fats if they now make up the majority. How much protein you need and why the numbers on the package are easy to misinterpret.
The breakdown follows a sequence: first the structure, then the practice. If you've already figured it out and want to take action, start with the section on getting started and the first month.
How many carbohydrates are left for the day
A maximum of 50–70 grams per day. This is not “zero carbohydrates” and not a ban on vegetables.
Greens, salad, cabbage, cucumbers, avocado, and a small amount of berries easily fit within this limit. What does not fit is anything that causes a rapid rise in blood sugar.
You won’t have to count grams forever. After two weeks, people know their usual foods by heart, and counting turns into the habit of checking the ingredients.
What is leaving and what takes its place
| Leaving | Replaces |
|---|---|
| Bread, baked goods, grains | Vegetables, greens, salad up to 300 g per day |
| Potatoes and corn | Avocado, olives, nuts 20–30 g |
| Sweet fruits, juices | Berries in small amounts |
| Sugar and confectionery | Chocolate 85% and above, 10–20 g |
| Ready-made sauces and dressings | Oil, apple cider vinegar, lemon |
Why fats become the main fuel
When there are few carbohydrates in your day, the body needs another source of energy, and fat becomes that source: both the fat that comes from food and the body's own.
The plate rule helps you avoid counting: half vegetables, one quarter protein, one quarter fats.
A daily ceiling, not a mandatory requirement
- Nuts 20–30 grams
- 85% chocolate and higher 10–20 grams
- Added oil 10–20 grams
- Fat is not "topped up to the target" with spoonfuls of oil: it remains a source of calories
How much protein is needed
From 1.2 to 2 grams per kilogram of body weight. This refers to pure protein per day, not the weight of the meat or fish on the plate.
A woman weighing 70 kilograms: 1.2 grams per kilogram gives 84 grams of protein, 1.6 grams per kilogram gives 112. If she is losing weight and training, a practical target is approximately 85–110 grams of protein per day. For comparison: 120 grams of chicken breast contains about 27 grams of protein, meaning one serving covers a quarter of the daily requirement.
It’s only difficult for the first 3 days. Your mood may drop and apathy may set in. This is the body’s temporary resistance.
What happens to appetite
There are no snacks at all in this approach. The entire daily intake fits into two or three meals, each until you are full.
This does not work through willpower. When there is enough fat and protein on the plate, blood sugar does not spike, and two hours later you are not drawn to the refrigerator. If you are, the previous meal was most likely too small.
Meals are arranged within an 8–10-hour window, for example: 10:00, 13:00, 18:00. It only makes sense to reduce three meals to two when one of them is genuinely unnecessary for several days in a row. There is no schedule here, and there is no need to aim for one meal a day.
Frequently asked questions
How is this different from strict keto?
By the flexibility of its limits. Keto keeps carbohydrates noticeably lower and monitors the state in which the body switches to ketones. A moderate low-carb diet does not require such strictness, and it is incorrect to apply keto's restrictions to it.
Do you need to count calories?
It’s not the amount of food that matters, but its composition. Calories still count, but with filling meals made up of fats, protein, and vegetables, people usually eat less without doing the math. This isn’t permission to eat without limits: oil and nuts are still high in calories.
Is fasting mandatory?
No. Low-carb eating and intermittent fasting are two independent tools. A 12–14-hour overnight break is possible without keto, and a low-carb plate works without extending the windows.
How much water should you drink, and do you need salt?
Aim for about two liters of fluids per day, more in hot weather and on training days; if you have kidney or heart disease, the amount is determined by your doctor. Salt is important during the first few weeks; aim for 3–5 grams per day, but do not take salt, potassium, or magnesium supplements “just in case” — if you have high blood pressure or heart disease, your doctor decides.
Where to start this week
Remove what gives you a quick sugar hit
While this sits on the shelf, the decision is made anew every evening.
Put together one typical day
Three meals, each with protein and vegetables, nothing in between. One day, not a week: then it will become clear what is missing from the fridge.
Add fat gradually
If you previously ate little fat, start with half or a third of the recommended portions. Feeling heavy after lard or bacon means the portion should be halved.
What to do tomorrow morning
- Remove sugar, bread, grains, potatoes, and sugary drinks from the kitchen
- Buy greens, avocado, eggs, fatty fish, olive oil, nuts
- Fit the day’s meals into three meals within an 8–10-hour window, with no snacks
- Keep water on hand: aim for about two liters a day
- Do not start on the same day as a new training routine
