The keto diet is a very low-carb, high-fat diet that is popular for its weight loss effects. It encourages ketosis, a metabolic state in which your body burns fat as its primary source of energy instead of carbohydrates. As the diet is very strict, it is natural to wonder whether cheat meals or days are allowed, or whether this will kick you out of ketosis.
Cheat meals or days are common strategies for strict diets. The idea is that by allowing yourself short periods of indulgence, you are more likely to stick to the diet in the long term. While cheating may be helpful for some eating patterns, it is not ideal for the keto diet. This is because the keto diet relies on your body staying in ketosis. To stay in ketosis, you need to eat fewer than 50 grams of carbohydrates per day. Eating more than 50 grams can kick your body out of ketosis. As carbohydrates are your body's preferred energy source, your body will use them over ketone bodies (the main source of fuel during ketosis, derived from fats) as soon as a sufficient number of carbs are available.
If you do cheat on the keto diet, you will likely be kicked out of ketosis. To re-enter ketosis, you will need to strictly follow the keto diet again, which can take several days to a week, depending on your carb intake, metabolism, and activity levels.
Cheating on the keto diet may result in weight gain, but this is typically water weight rather than fat gain. However, it is important to note that suddenly reintroducing a high-carb meal to a ketogenic diet may damage your blood vessels. Additionally, it is easy to overeat while cheating, which may sabotage your weight loss efforts and promote unhealthy eating habits. Therefore, while the occasional cheat meal or day on the keto diet may not completely derail your progress, it is generally not recommended.

What You'll Learn
A single cheat meal can knock you out of ketosis
The keto diet is a very low-carb, high-fat diet that is popular for its weight loss effects. It encourages ketosis, a metabolic state in which your body burns fat as its primary source of energy instead of carbohydrates. This diet is very strict, and it may be challenging to stick to it 100% of the time.
A single cheat meal can easily exceed your daily carb allowance and take your body out of ketosis. For example, a slice of pizza contains 34 grams of carbohydrates, a banana has 27 grams, and a doughnut contains 22 grams. These are all well above the daily limit for ketosis.
If you do cheat and consume a high-carb meal, it will take several days to one week to get back into ketosis, depending on your carb intake, metabolism, and activity levels. In the meantime, your weight loss may be disrupted.
To resist cheating on the keto diet, you can try keeping tempting foods out of the household, enlisting the help of an accountability partner, practising mindfulness, and making a solid daily diet plan.
Strategies for getting back into ketosis after a cheat meal
- Try intermittent fasting: Combine intermittent fasting with the keto diet to help your body shift its fuel source from carbs to fat.
- Track your carb intake: Take note of your daily carb intake to ensure you don't underestimate it.
- Try a short-term fat fast: Fat fasts like egg fasts are very high-fat, low-carb diets meant to last only a brief period and may help expedite ketosis.
- Exercise more: Physical activity depletes your glycogen stores, which are your body's stored form of carbs, promoting ketosis.
- Try a medium-chain triglyceride (MCT) supplement: MCTs are a rapidly absorbed fatty acid that's easily converted into ketones.

You can gain water weight
When you eat carbs, your body stores them as glycogen. For every gram of glycogen, your body holds on to three or four grams of water. This is why you may gain weight after eating a carb-heavy meal.
If you're on a keto diet and you cheat, you might gain some weight from the carbs you eat, but it's not likely to be a lot. In fact, most of the weight you gain will be water weight. This is because your body will store the carbs as glycogen, and for every gram of glycogen, your body will hold on to three or four grams of water. So, if you eat a lot of carbs during your cheat meal or day, you might see a slight increase in your weight, but it's mostly just water weight.
The good news is that this water weight is usually temporary. Once your body uses up the glycogen for energy, it will release the water, and you will lose the water weight. This can take a few days to a week, depending on your body and how much you cheated.
It's important to note that cheating on the keto diet can also kick you out of ketosis, which is the metabolic state where your body burns fat as its primary source of energy. If you want to stay in ketosis, it's best to avoid cheat meals or days. However, if you do cheat, don't be too hard on yourself. Just get back on the keto wagon as soon as possible, and you'll be back in ketosis before you know it.

It can take several days to get back into ketosis
If you've cheated on your keto diet, you're likely out of ketosis. But don't panic! It takes anywhere from one day to a week to get into ketosis in the first place, but the process is usually much quicker the second time around.
There are a few factors that influence how long it will take to get back into ketosis: your carb intake, metabolism, and activity levels. If you've been in ketosis for more than three to six weeks, it will be easier to get back into it quickly. This is because your body is likely getting 70% of its energy from fat, and you're fat-adapted. Other indicators that you'll return to ketosis swiftly include if you've been in ketosis for four or more weeks before your cheat meal, if you got into ketosis with ease when you first started, if you're exercising regularly, and if you didn't go overboard with your cheat meal.
If you want to get back into ketosis as soon as possible, there are a few techniques you can try. Firstly, intermittent fasting can help your body shift its fuel source from carbs to fat. Secondly, track your carb intake to ensure you don't underestimate it. Thirdly, try a short-term fat fast like an egg fast, which is a very high-fat, low-carb diet meant to last only a brief period. You can also try exercising more, as physical activity depletes your glycogen stores (your body's stored form of carbs), which in turn promotes ketosis. Finally, you can try a medium-chain triglyceride (MCT) supplement, which is a rapidly absorbed fatty acid that's easily converted into ketones.
Remember, the best way to know if you've reached ketosis is to test your ketone levels. You can use tools like ketone breath meters, blood ketone meters, and keto urine strips to do this.

You might experience a sugar crash
When you eat carbs, your body releases more glucose into your bloodstream. Your body then sends out insulin to push this glucose out of your blood and into your cells to be used for energy. If your bloodstream is constantly pumping glucose, you can become insulin resistant, which can cause your blood sugar to have a tough time returning to healthy levels. This can lead to a sugar crash, which may result in:
- Trouble concentrating
- Crankiness and irritability
- Low energy and brain fog
Additionally, since your sensitivity to sugar is elevated during the keto diet, you may experience these negative side effects more intensely.
How to Manage a Sugar Crash
If you're experiencing a sugar crash after cheating on your keto diet, you can try the following:
- Take a supplement like Perfect Keto Blood Sugar Support, which aids in healthy carbohydrate metabolism when you've consumed more carbs than you should.
- Increase your water intake and ensure you're getting enough electrolytes.
- Get plenty of quality REM sleep to give your body a chance to reset and repair itself.
- Try an intermittent fast to help use up your glycogen stores and enter ketosis more quickly.

You might have trouble getting back on track
Cheating on your keto diet can lead to a number of setbacks, and you might have trouble getting back on track. Firstly, it is important to note that the longer you cheat, the more weight you are likely to gain, and the longer it will take to get back into ketosis and lose the weight. This is because a cheat day can easily turn into multiple days of cheating, and the more you cheat, the more challenging it becomes to get back into a fat-burning state.
To get back on track, you will need to strictly adhere to the keto diet again to re-enter ketosis, which can take several days to a week, depending on your carb intake, metabolism, and activity levels. Here are some tips to help you get back on track:
- Intermittent fasting: Combine intermittent fasting with the keto diet to help your body shift its fuel source from carbs to fat.
- Track your carb intake: Keep a close eye on your daily carb intake to ensure you don't underestimate it.
- Try a short-term fat fast: Fat fasts like egg fasts are very high-fat, low-carb diets meant to expedite ketosis.
- Exercise more: Physical activity depletes your glycogen stores, which are your body's stored form of carbs, thus promoting ketosis.
- Try a medium-chain triglyceride (MCT) supplement: MCTs are easily converted into ketones, which can help you reach ketosis faster.
In addition to the above tips, here are some general strategies to help you get back on track and avoid cheating in the future:
- Practice mindfulness: Pay attention to your body and its cues to help resist cravings and emotional eating.
- Plan your meals and snacks: Having a solid dietary plan makes it less likely that you'll get hungry during the day and gives in to temptation.
- Make your diet enjoyable: Incorporate a variety of keto-friendly meals to make your diet more enjoyable and reduce cravings.
- Keep tempting foods out of the house: Out of sight, out of mind! Keeping treats and other tempting, high-carb foods out of reach can make cheating more difficult.
- Get an accountability partner: Having a buddy or accountability partner can help you stay motivated and committed to your diet.
Remember, it is normal to experience setbacks, and cheating on your keto diet does not mean you have failed. The most important thing is to get back on track as soon as possible and stick to your plan.
