How long does it take to get into ketosis?

It’s a dream to achieve ketosis and enjoy the benefits; however, what is the time frame? In today’s fast-paced life, it is common to want quick results! When you cut out the carbs and start consuming more nutritious, healthy fats that are delicious, just how much time will it take to enter ketosis?

When Will You Achieve Ketosis?

The time needed to reach ketosis is dependent on the individual.

If you’ve cut down the carbs, you consume about 20-50 grams daily. The typical time is about 2-4 days. For some, it may require a week or more.

Be aware that you may have some issues transitioning from burning carbohydrates to burning fat. The keto flu is commonly characterized by nausea, fatigue, and increased thirst. Please read our article about methods to reduce or avoid symptoms of the keto virus!

Why Does it Take Longer for Some People?

People who are healthy and metabolically prepared may reach ketosis more quickly than those who aren’t.

If you generally consume a high-carbohydrate diet, it could take longer to get to ketosis than people who follow a moderately-low-carbohydrate diet. The body must deplete glycogen reserves before reaching ketosis. If your body isn’t required to utilize glucose (sugar) to fuel itself, Your body’s glycogen stores (connected glycogen molecules) in your muscles and your liver.

Some individuals are slower to produce ketones due to a variety of factors like:

  • Metabolism
  • Age
  • Too many carbs
  • Insufficient fat intake
  • Consuming too much protein (gluconeogenesis)
  • Exercise is not enough
  • Sleep deprivation
  • Stress

Some people can begin producing ketones while eating more carbohydrates, as high as 70-90 grams a day; others must limit their intake to less than 25-30g. The ketogenic diet cuts down on carbs to about 50 grams a day.

It could be necessary to lower your carb intake. You may also be eating excessive protein, which could cause your body to engage in the process known as gluconeogenesis. It is a process in which your body transforms proteins into sugar. Too much sugar inhibits ketone production.

Exercise can speed up your transition into ketosis by helping the body to eliminate its carb stores more quickly.

You can try experimenting with and testing your ketones to find out what’s right for you.

How Do You Know You’re in Ketosis?

In addition to how you feel and the food you eat, measuring your ketone levels is the most effective way to tell whether you’re in ketosis. You can test ketones by urinating breath, blood, or urine. Find out more information about the ketones test.


It could take anywhere from two to three days to reach ketosis. However, it may take up to a week or more for sure.

The best method of determining whether you’re experiencing ketosis is by measuring your ketone levels with breathing, urine, and a blood measuring instrument.
