How Long Does It Take to Get into Ketosis? 

To recap, ketosis is a metabolic state where your body converts fat into ketones as a source of energy when there is insufficient sugar for fuel. This is why the best way to reach ketosis is to reduce your intake of carbs.  

The time it takes to enter ketosis depends on the individual person and their diet. It usually takes 2-4 days to get into the state if you only eat 20-50 grams of carbs per day. However, some can take a week or longer due to lack of exercise, metabolism, age, and protein intake.  

How Do I Know I’m in Ketosis? 

As your body transitions into ketosis, you experience symptoms known as the keto flu, such as headache, fatigue, nausea, bad breath, and increased thirst. This can be a sign of your body entering ketosis.  

The best way to know for sure is by measuring your ketone levels with tools like a breath meter, urine sticks, or a blood ketone meter.

To use a blood ketone meter, all you have to do is use the pin to prick your finger and draw blood, then let the strip come in contact with your blood.  

A blood ketone level above 0.5 mmol/l means you are in light nutritional ketosis. For weight loss, the ideal ketone level is between 1.5 and 3.0 mmol/l. 

How to Enter Ketosis in 24 Hours? 

Here are some effective ways to get into ketosis in less than a day. 


Fasting can be a great way to get into ketosis in 24 hours. By delaying the time in which you eat your first meal, your body will find itself deprived of carbs and will then switch to an alternate fuel source (in this case, fats).

It is at this point that your body will start to enter the state of ketosis. An easy way to do this is by skipping breakfast completely and having your first meal after midday.  

There is a popular fasting method that is practiced by a lot of people called the 16:8 fasting. In this fasting method, you are not allowed to eat for 16 hours and then there will be an 8-hour eating window.

A suggested method to do this is to stop eating food at 8 pm and then not eat any food until noon the next day. 

MCT Oil 

What is one of the fastest ways to get into ketosis? MCT oil, also known as “medium chain triglycerides” oil is one of the fastest sources of energy. It goes straight to your liver and it is easily digested and quickly converted into ketones. 

As well as that, MCT oil is known to help curb your food cravings, increase mental clarity, and fight inflammation. An article from Dr. Axe states that it signals the brain that you are receiving enough energy so it helps you in controlling your calorie intake.  

MCT oil is highly recommended before fasting if you are trying to get into the state of ketosis in just 24 hours. Do not consume too much MCT oil as it has been known to cause digestive issues if more than the recommended dose is taken. 

Start with 1 tsp and slowly scale up to 1 tbsp per day as your body gets used to it. As for seasoned users, you can take up to 2 tbsp a day.  

Do Some Light Exercise 

Most people who start exercising on the keto diet will often find themselves exhausting themselves from doing too much too soon. This can have a negative effect and make it harder for you to get into the state of ketosis.  

When starting a keto diet, it is generally a good idea to only start with a low-intensity exercise because high-intensity exercise can increase the stress hormone cortisol.  

To start with, do some light cardio exercises such as walking or anything that does not require your heart rate to get too high. Avoid doing heavy exercises such as lifting heavy weights and sprinting at the beginning of your keto diet to allow time for your body to adjust to the new conditions. 

When your body switches its fuel source to fat for energy instead of carbs you then can start to do some higher intensity exercises.  

It is also important to do exercise on an empty stomach as it allows your body to use up stored glycogen in the muscles rather than from the food you’ve eaten prior to exercising.  

Remember, if you feel like fainting during exercise while fasting there’s always an option to snack on some keto-friendly foods. Take note of the word snack! 

Drink Plenty of Water 

Water is important for digestion and elimination of toxins. It also aids in metabolizing fats and reducing weight. This means your liver needs assistance from water to mobilize fat as quickly as possible and produce ketones more quickly. 

The ketogenic diet is generally dehydrating in nature, that is why you should increase your daily water intake.  

Take Exogenous Ketones 

Exogenous ketones or ketone supplements also prove to be effective in giving you a ketogenic boost. They elevate the levels of ketones in the blood and help induce ketosis quickly.

Unlike natural ketones produced in the body, some exogenous ketones contain added electrolytes for more benefits.  

Is It Safe Trying to Enter Ketosis in 24 Hours? 

Studies that were conducted have shown evidence that getting into ketosis is not harmful to the human body. If at all, it only helps with numerous health issues that you may be suffering from. 

People who are suffering from bipolar disorder can benefit from keto dieting and its mood stabilizing benefits. Ketogenic dieting has also been known to treat people with epilepsy along with seizure treatment.

It has also been known to treat mental illnesses such as Alzheimer’s, ADHD, Parkinson’s and autism. 

There are limited studies about the safety of getting into ketosis in as quickly as 24 hours. Attempting to get in this state means altering your natural body processes. Many want to get in ketosis quickly in order to lose weight, manage type 2 diabetes, and improve their heart health.  

Although there are no mentioned side effects of getting into ketosis rapidly, it is still not for everyone. Especially those with type 1 diabetes due to a higher risk of developing ketoacidosis. 

Ready to Get Into Ketosis?

Getting in ketosis within 24 hours is not an easy task. A proper diet and the right activity levels are needed to help you reach your goal. 

You can see for yourself that there is no harm in pursuing a ketogenic diet. Keto dieting has been shown in the past to have been used to treat a host of illnesses. And there are plenty of other benefits as well as the weight loss that accompanies it.

So, fear not, as long as you follow the keto diet regime properly and consistently you should get the results you are looking for! 

You will be impressed to see how this keto diet plan can be more effective and efficient when accompanied by exercise, water, supplements, fasting, and proper monitoring.
