What Is Carb Intake on the Keto Diet?

A reduction in carbohydrate consumption and an increase in fat intake characterizes the ketogenic (or “keto”) diet. This causes ketosis, a metabolic condition in which fats are used for energy instead of carbohydrates. But what is carb intake on the keto diet?

Foods high in fat and low in carbohydrates make up the ketogenic diet. Some fruits and vegetables, grains, legumes, and even some veggies are off-limits on this diet. That is why measuring calorie intake is essential for the keto diet.

An analysis of various ketogenic diets conducted in 2018 concluded that 50 g of carbs per day was the upper limit for maintaining ketosis.

On the ketogenic diet, a woman needs 40–50 grams of protein per day, while a man needs 50–60 grams.

However, carbs, proteins, and fats can all be consumed in varying quantities on the numerous ketogenic diet plans.

A person consumes 70% fat, 20% protein, and 10% carbohydrates on a standard ketogenic diet.

On the cyclical ketogenic diet, you will have 5 days to consume very few carbohydrates and 2 days when you have much more.

An individual on a targeted ketogenic diet can consume more carbohydrates before, during, and after intense physical activity.

The macros for a high-protein ketogenic diet are 60 percent fat, 35 percent protein, and 5 percent carbohydrates.

Experts that prescribe ketogenic diets are more likely to propose the regular ketogenic diet because it has been the subject of the most research.

How to Calculate Carbs?

When following the ketogenic diet, paying attention to the “net carbohydrates” per serving is essential.

Net carbohydrates are determined by subtracting the fiber content from the total carbs in a given serving. Sugar alcohol concentration should be reduced by half if the dish has been prepared. Nutrition facts are required to be listed on all packaged foods.

Below, we explore these concepts and the corresponding calculation in greater detail:

Net Carbs

Included here are both digestible and indigestible carbohydrates, meaning your body can’t convert the whole serving into glucose.

These can be broken down into energy by the body. Hence they’re also known as digestible carbohydrates. Subtract the fiber content from the total carbs to get the net carbs per serving. Additionally, halve the sugar alcohol concentration if the dish has been prepared.


Fiber is a carbohydrate that can’t be broken down into glucose. Therefore it can’t be used for energy in the body.

If you want to know how many net carbohydrates something has, subtract the fibre content from the total carbs.

Alcoholic sugar

For processed goods, half the quantity of sugar alcohol must be subtracted from the total carbohydrate count to get the net carbohydrate content.

The body does not digest all sugar and alcohol on the keto diet. Hence they have less impact on blood sugar levels than table sugar.

The following are some common sugar alcohols:

  • Sugar alcohols 
  • Sorbitol
  • Xylitol
  • Mannitol
  • Isomalt
  • Maltitol
  • Lactitol
  • Hydrogen

How Does the Keto Diet Work?

Sugar is produced when a person eats carbohydrates, and this sugar is used as fuel by the body’s cells.

When carbohydrates are severely restricted, the body turns to fat stores for fuel. This leads to a decrease in blood glucose levels.

This causes the body to release ketones, acids found in the blood and urine as a byproduct of the fat-burning process. Ketosis is the metabolic state in which fat is used for energy, with the accompanying release of ketones.

Reduced insulin production and fat storage are both side effects of the metabolic state of ketosis. If weight loss is an objective, the ketogenic diet may be helpful because it reduces hunger and speeds up the metabolism. Type 2 diabetes may be easier to control on this diet due to its effect on glucose levels.

Functions of Carbohydrates in the Human Body

Inherently, your body is set up to favor the burning of carbohydrates. Therefore, if carbohydrates are readily available, the body will utilize them for fuel.

If you dramatically reduce your carb intake, your body will start burning fat, either what you eat or what you already have stored. You may feel under the weather for a few days while your body adjusts to running on fat rather than carbs for fuel.

“Keto flu” describes the symptoms experienced by the vast majority of persons who try highly low-carb diets. It’s easy to lose motivation for a healthy diet if you’re sick for a few days. You should give your body a few days to acclimate to the new routine, but realize that full adaption could take a few weeks.

Consider your preferences and needs while deciding whether or not to stick with the diet. Before beginning a new diet, you should always talk to your doctor or a dietician. It may take a few days to feel better on a low-carb diet, but it may take a few weeks for your body to adapt. Keep going with your diet; patience will pay off.


So, what is carb intake on the keto diet? Carbohydrate intake on the ketogenic diet should be kept to a maximum of 50 g per day. High-carb foods are typically replaced with fatty foods like eggs, dairy, fresh meat, and fish.

It’s important to read food labels because some wheat products, including fruits, vegetables, beans, and legumes, might have a lot of carbohydrates. Consult your doctor before beginning a ketogenic diet to be sure the transition is safe for you.

Obesity and type 2 diabetes are two health problems that could be helped by following a low-carb diet. However, restricting carbs alone won’t lead to weight loss or improved health. Modifying your diet and gradually adding more physical activity is the most excellent approach to losing weight and keeping it off permanently.

Those who try to stick to a ketogenic diet for an extended period generally find that they cannot do so and that once they return to eating carbohydrates, the weight quickly returns. Get plenty of exercise and eat healthily to feel your best.

Frequently Asked Questions

How many grams of carbs per day does it take to enter ketosis?

To enter ketosis, most people need to reduce their daily carbohydrate intake to below 50 grams. You should be aware that this severely limits your carbohydrate choices, leaving you with only veggies and moderate amounts of berries. Subtract the quantity of fiber, sugar alcohols, and other carbs that the body cannot absorb from the total to get your net carbs.

How many grams of carbs should a woman take each day?

A daily carb intake of 100–150 grams may be optimal for those who engage in strenuous physical activity or who wish to maintain their current weight. If you want to lose weight quickly, your doctor may recommend cutting your caloric intake to less than 50 grams daily.

What about limiting yourself to 50 grams of carbs daily?

What about limiting yourself to 50 grams of carbs daily?

Cutting your daily carb intake to 50-150 grams will help you lose weight and feel better (exact numbers vary according to your total caloric intake). The great thing about restricting carbs is that you can still enjoy delicious food without worrying about your calorie intake.

Can I still lose weight if I limit my daily carb intake to 65 grams?

Blom recommends that those trying to shed pounds keep their carbohydrate consumption to no more than 65% of their total daily caloric intake. Reduced space for protein and good fats means they can play a more critical role in helping you feel full and lose weight.
