How To Maintain Ketosis

Not sure how to get into ketosis (and stay there)? Learn how to eat a keto diet and test your ketone levels so you can lose weight, boost brain health & more.


The ketogenic diet is all the rage right now, and more people are learning about the benefits of ketosis on their health and weight loss goals. However, there’s still some confusion around the process itself and the correct ways to maintain ketosis.

This information will help you maintain a steady state of ketosis safely and efficiently, no matter your needs.

Getting into Ketosis

First things first. Before we can maintain ketosis we have to get understand what is ketosis and get into this primal metabolic state. Ketosis occurs when the body has little to no access to carbohydrates, its normal source of fuel, and begins breaking down and burning fat for energy instead. The ketosis process can have many benefits including:

  • Curbed hunger and faster weight loss
  • Improved blood sugar regulation
  • Enhanced cognitive performance
  • Better mental focus
  • Less chance of inflammation
  • Reducing risk for conditions like type II diabetes

When the body’s in ketosis, fats are broken down and ketone bodies, or “ketones,” are created for the body to use for energy.

Three Main Ways of Maintaining Ketosis

  • Long-term
  • Short-term
  • Cyclical

The way you use the ketogenic diet depends on your specific needs, but what’s important is making sure you maintain a state of ketosis during the full time you’re on keto. This is not the same as simple going low-carb, and it requires some extra effort and tracking. However, the results are worth the extra work!

Short-Term vs Long-Term Ketosis

Just as it sounds, the only difference between short- and long-term ketosis is the amount of time you properly follow the ketogenic diet. The standard version of the ketogenic diet involves eating around 20-50 grams of net carbs per day to keep the body in ketosis, although the exact amount depends on each person. Check out our article about net carbs and their impact on remaining in ketosis.

Long-term ketosis is maintained for a more extended period of time and often gets easier as the body becomes keto-adaptive, or more efficient at using ketones for fuel.

Maintaining a Long-Term Ketogenic Diet

It’s important to note that following the ketogenic diet 100% all the time might not be feasible or desirable for everyone.

Sometimes you might have periods of higher carb intake, such as before exercise, that will take you out of a state of ketosis. Some people might experience too low energy or side effects like constipation or kidney stones if they’re fully in ketosis for an extended period of time.

This is where shorter-term ketosis can be used to put the body into its fat-burning state long enough to reap the benefits but still fit into your lifestyle. For example, those who are very active might use a targeted ketogenic diet where they eat 25-50 grams of carbs only before a workout to fuel them through it, then continue eating ketogenic the rest of the time.

Exogenous ketones—ketones you take as supplements—can also come into play here.

Another popular option for those not able to do keto long-term is a cyclical ketogenic diet.

Maintaining Cyclical Ketosis

Cyclical ketogenic diets are a more flexible version of the plan. They usually include eating keto for several days followed by a couple days of eating higher levels of carbohydrates. Unlike short- and long-term ketosis, the goal here isn’t to stay in ketosis all the time but to make the diet more flexible.

How to Maintain Your Ketosis

No matter which version of keto you do, here are some basic tips that will help you reach and maximize your state of ketosis, as well as avoid some common mistakes people make when first starting a ketogenic diet:

Find Your Individual Macros

Remember the golden ketosis formula: Low carb, adequate protein, and high fat.

what is the ketogenic diet

The exact amounts of carbs, proteins, and fats can vary per person, so you’ll have to do some experimenting to find out what works best for you. However, for a standard ketogenic diet, it typically falls around 60% fat, 35% protein, and 5% carbs. Use the keto macro calculator to find your personalized macros on keto.

Track Your Carbs to Stay in Ketosis

As outlined above, carb intake should be kept very low (and fat high) so the body utilizes its natural fat-burning capabilities. You won’t ever reach ketosis if you aren’t diligent about finding the carbohydrate count that is just right for your body.

The best way to determine the exact carb count that’s right for you is by figuring out your total daily calorie intake. Again, you can use the keto macro calculator for this.

Test Your Ketone Levels

What’s great about ketosis is that its not just a diet, it’s literally a measurable state of metabolism and you can always test where you stand. Now, knowing your perfect amount of protein and carbs is all fine and dandy, but the most important piece of the puzzle is whether or not your body is creating ketones. If there aren’t any ketones present, you still haven’t entered ketosis.

There are three ways to test your ketone levels:

How To Test Your Ketones

Read our guide on testing ketones here to weigh the pros and cons of each method. Then, plan to test your ketone levels regularly as well as re-weigh yourself every couple of weeks to measure your progress, if weight loss is your goal, and also make sure your macros are still within the right amounts to be at a caloric deficit.

No matter what, remember that eating fewer processed, high-glycemic carbs is a great choice for you and your health in the long run. Maintaining ketosis can take a little trial and error and extra tracking at the beginning, but you’ll ultimately reap the long-term rewards from this lifestyle shift.


Test, don’t guess! Routinely check your ketone levels to assess if you are effectively maintaining ketosis. If you aren’t, simply review your day and eating habits and make some intelligent alterations and test again. Try new things. Try ketone supplementation, MCT oil powder, scaling back on carbohydrates even more, modified fasting, more sleep. There are endless amounts of resources and articles on the internet on how to increase your ketone levels.

  4. Hi Everyone,

    I am so grateful for all the useful information here. Thank you Mr Cunningham! I need to loose 30 pounds to be in normal BMI range. I have never gone on a special diet before. Today is my third day on keto diet. I am vegetarian and am finding it challenging!

  5. Thanks for sharing this article. I am leaning towards a Keto-Mediteranean diet to lose weight. I’ve started this new diet on May 7 and tomorrow is my one month. I’m enjoying it and taking my doctors advice to eat more food daily. Keto should always be above 1.51 which is something I’ve learned this past week.

  6. My body does not remain in ketosis. I use test strips several times a day and one will show I’m there and the next one will show less ketones. I use a reputable Keto pill and use the oil in my coffee. I’m 71 and am carrying 20 or so extra pounds. I believe I’m doing it properly but my body does not seem to be staying in the ketosis state. I’ve been following the diet and except for a couple days when I ran out of pills, have taken the supplements. I have lost 20 lbs. How does your body know to use stored fat instead of dietary fat? In a word, HELP!

    1. Hi there, I’m sorry to read about your struggle. What kind of foods do you eat though? Make sure limit your carb and sugar intake to a minimum as well.
