How many carbohydrates can you have per day on LCHF
A maximum of 50–70 grams of carbohydrates per day. This is not «zero carbohydrates»: leafy greens, salad, cabbage, cucumbers, avocado, and a small amount of berries fit into this limit easily. Anything that causes a rapid rise in blood sugar does not.
Why exactly 50–70?
This is the upper limit at which the body stops running on glucose and switches to fat as its main fuel. Below it begins the territory of strict keto with its own rules; above it, there are enough carbohydrates for blood sugar to keep fluctuating, along with your appetite.
It is important that this is a ceiling, not a daily target. You do not need to deliberately reach 70 g.
What fits into the limit and what does not
| Fits | Does not fit |
|---|---|
| Salad, leafy greens, spinach | Bread, baked goods, grains |
| All types of cabbage, broccoli | Potatoes, corn, beets |
| Cucumbers, zucchini, asparagus | Sweet fruits, dried fruit |
| Tomatoes, bell peppers | Juices, soda, sweet tea |
| Avocado, olives | Honey, syrups, sugar |
| Berries in small amounts | Milk and sweetened yogurts |
Should you count net carbohydrates or total carbohydrates?
It is easier to count everything and not overcomplicate things. Fiber barely raises blood sugar, so with above-ground vegetables the difference between «total» and «net» carbohydrates is small and does not significantly affect the 50–70 g limit.
If you start by subtracting fiber, the very first week will turn into arithmetic instead of eating. The point is to stop counting after two weeks.
Where is hidden sugar lurking?
In foods that look like ordinary food. Ketchup and ready-made sauces, salad dressings, marinades and BBQ sauces, sweetened yogurts, granola, protein bars, flavored plant milk, ready-made coffee drinks, sausages, and pâtés.
On the ingredients list, it can be called different things: glucose syrup and glucose-fructose syrup, dextrose, maltose, invert sugar, agave syrup, rice syrup, fruit juice concentrate, honey. The mere presence of such a name does not make a product bad — the important things are the amount and its place in the ingredients list: the closer to the beginning, the more there is.
How long will you have to count?
About two weeks. During this time, you memorize your usual foods, and counting turns into a habit of looking at the ingredients list rather than into a spreadsheet.
During the first week, it is easier not to count grams, but simply to read labels in the store. That is enough to remove most hidden sugar from your shopping basket.
What do 50–70 grams look like on a plate?
It is easiest to imagine this through an entire day rather than individual foods.
A large 300-gram bowl of green salad provides just a few grams of carbohydrates. Half an avocado is also low in carbohydrates. A handful of berries, 50 grams, adds about five. A couple of spoonfuls of flax and chia add almost nothing, because most of their carbohydrates come from fiber.
Now for the foods that use up the entire limit. One banana or one slice of bread takes away half the daily limit. A glass of orange juice contains about the same amount. A serving of potato or rice as a side dish uses up the entire limit, leaving no room for vegetables that day.
This leads to a rule that works without a calculator: if your plate contains no bread, grains, potatoes, or sweets, you have almost certainly stayed within the limit.
Do you need to lower the limit if your weight is not changing?
No, it is worth checking something else first. Going below 50 grams is already the territory of strict keto with its own rules and contraindications, and you should not move there on your own just to speed things up.
More often, the problem is not carbohydrates. Hidden sugar in sauces and ready-made products. Calorie-dense additions that go uncounted: nuts in the evening, an extra spoonful of oil, a piece of cheese eaten on the go. Meals that are too small, followed by overeating in the evening. Lack of sleep and stress, which can keep your weight from changing even with a perfect diet.
If all of this has been checked and nothing has changed for several weeks in a row, the issue is not cutting the limit but seeing a doctor.
Common mistakes
- Counting «healthy» foods as free: bananas, honey, and dried fruit provide carbohydrates just like cookies
- Forgetting about drinks: lattes, juice, and sweet tea can easily use up half the daily limit
- Trying to reach the limit of 70 g, as if it were a target
- Counting net carbohydrates from day one and giving up after three
When this is not suitable
Do not restrict carbohydrates to 50-70 g on your own during pregnancy and breastfeeding: the ADA states a minimum of 175 g of carbohydrates per day for pregnant women; the reference value is higher during lactation.
With type 1 diabetes, as well as type 2 diabetes treated with insulin or medications carrying a risk of hypoglycemia, change the amount only together with your doctor — doses require adjustment. Chronic kidney disease, eating disorders, and adolescence should also be discussed separately with your doctor.
What to do tomorrow
Read the ingredient lists of four products
Sauce, yogurt, plant-based milk, any bar. Find sugar under another name in them.
Remove sugary drinks
This is the fastest half of the allowance to eliminate without any effort.
Build one day from vegetables, protein, and fats
And count carbohydrates — once, to see the scale.
