The keto diet is a very low-carb, high-fat diet that encourages ketosis, a metabolic state in which your body burns fat as its primary source of energy instead of carbohydrates. As the keto diet is very strict, you may find yourself tempted by the occasional high-carb food.
Cheat days and cheat meals are common strategies for strict diets. Cheat days allow you to break the diet's rules throughout the day, while cheat meals let you have a single meal that breaks the rules. The idea is that by allowing yourself short periods of indulgence, you're more likely to stick to the diet over the long term.
However, cheat meals and days are discouraged on the keto diet because they can easily break ketosis. Eating more than 50 grams of carbs can kick your body out of ketosis, and as carbs are your body's preferred energy source, your body will use them over ketone bodies (derived from fats) as soon as a sufficient number of carbs are available.
If you do decide to have a cheat meal or day, it's important to know how to recover and get back into ketosis. This process takes several days to a week, depending on your carb intake, metabolism, and activity levels. Some tips to help you get back into ketosis include trying intermittent fasting, tracking your carb intake, trying a short-term fat fast, and exercising more.
To avoid cheating, you can implement several simple strategies, such as practising mindfulness, planning out your meals and snacks, making your everyday diet enjoyable, and keeping tempting foods out of the house.

What You'll Learn
Cheat meals can kick you out of ketosis
Cheat meals or days are common strategies for strict diets. Cheat days allow you to break the diet rules throughout the day, while cheat meals let you have a single meal that breaks the rules. The idea of planned cheating is that by allowing yourself short periods of indulgence, you are more likely to stick to the diet over 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 carbs per day. Eating more than 50 grams can kick your body out of ketosis. As carbs are your body's preferred energy source, your body will use them over ketone bodies (derived from fats) as soon as a sufficient number of carbs are available.
Because 50 grams of carbs is a relatively small amount, a single cheat meal can easily exceed your daily carb allowance and take your body out of ketosis. A cheat day is almost certain to surpass 50 grams of carbs. In addition, some research suggests that suddenly reintroducing a high-carb meal to a ketogenic diet may damage your blood vessels. It is also easy to overeat while cheating, which may sabotage your weight loss efforts and promote unhealthy eating habits.
If you do choose to have a cheat meal, it is important to be mindful of the potential consequences. Eating a high-carb meal can take you out of ketosis, interfere with your weight loss and fat loss goals, and cause a spike in your blood sugar levels. It can also lead to a sugar crash, a temporary gain in water weight, and a return of cravings and keto flu symptoms.
If you do decide to have a cheat meal, there are some strategies you can use to minimise the impact. These include opting for keto-approved cheat meals, having cheat meals instead of cheat days, planning your cheat meals in advance, and tracking your daily intake to ensure you are not exceeding your weekly nutrition goals.
Ultimately, the decision to have a cheat meal or day on the keto diet is a personal one. If you are finding it difficult to stick to the diet consistently, it may be worth revisiting whether this diet is right for you. The best diet for you is one that you can stick to!

It's not detrimental to go off keto for a day
It is not detrimental to go off keto for a day. In fact, it is entirely possible to include cheat meals on your keto diet and still lose weight. However, how drastically and how often you go off keto will certainly affect your progress in the long run, and you might end up undoing a lot of hard work if you are not careful.
Ketosis vs Calorie Control
Ketosis could have some potential health benefits, but it's likely not the main reason you are losing weight—calorie control is. So, as long as you are not going overboard with cheat days and are maintaining calorie control overall, all those carbs are not going to destroy all of your hard work.
Cheat Days and Mental Health
Cheat days have become a popular theme with many diets and for good reason. In fact, many experts have embraced diet cheats as a way to teach a more balanced approach to healthy eating. Research says there may actually be some benefits to going off your diet. Including a strategic diet cheat may have some psychological benefits like reduced cravings and the ability to stick to your meal plan better overall.
How to Cheat the Right Way
If you are going to go off your diet, it is much easier to stay on top of your overall nutrition and calories with cheat meals compared to entire keto cheat days. One large cheat meal can add 1,000 or more calories to your day, while a whole cheat day will add much more and potentially undo all of your hard work from the week.
The easiest way to ensure your diet cheats don’t ruin your progress is to plan for them. Pick which meals you’re going to cheat and budget some calories and carbs in advance if you can.
How to Get Back into Ketosis
If you've cheated on keto, you’re likely out of ketosis. Once out, you’ll need to strictly follow the keto diet to reenter ketosis. This process takes several days to 1 week, depending on your carb intake, metabolism, and activity levels. Here are a few tips to help you get back into ketosis:
- Try intermittent fasting. Combining intermittent fasting with the keto diet may help your body shift its fuel source from carbs to fat.
- Track your carb intake. Taking note of your daily carb intake ensures that you don’t underestimate it.
- Try a short-term fat fast. Fat fasts like egg fasts, which may help expedite ketosis, are very high-fat, low-carb diets meant to last only a brief period.
- Exercise more. Physical activity depletes your glycogen stores, which are your body’s stored form of carbs. In turn, this promotes ketosis.
- Try a medium-chain triglyceride (MCT) supplement. MCTs are a rapidly absorbed fatty acid that’s easily converted into ketones.

Cheat days can increase heart health risks for diabetics
It is possible to include cheat meals on your keto diet and still lose weight. However, how often you cheat on your keto diet will affect your progress and health in the long run.
Cheat days and diabetes
For people with diabetes, cheat days can be dangerous. If you have type 2 diabetes, your body converts carbohydrates from food and drink into glucose at a higher-than-normal level. In response, the pancreas secretes insulin. But the insulin is ineffective, so your blood glucose levels continue to rise, and more insulin is secreted in response. This can gradually exhaust the pancreas, causing the body to produce less and less insulin. This insulin resistance can result in even higher blood sugar levels, putting you at risk for hyperglycemia.
Cheat days and heart health
If you are following a keto diet to manage blood sugar levels, cheat days can increase heart health risks. Eating a high-carb meal will take you out of ketosis and cause your blood sugar to spike. This can be dangerous for people with type 2 diabetes, cardiovascular disease, or poor cardiovascular health.
If you are diabetic, it is not recommended to eat a cheat meal while maintaining daily blood sugar control. Even a cheat meal once every three months puts your blood sugar at dangerous levels four times a year. If you are diabetic, it is best to maintain a balanced diet and avoid putting extra stress on your serious health issues.

Cheat days can cause blood sugar spikes
When you're on the keto diet, your body is in a state of ketosis, which means it's burning fat for energy instead of carbohydrates. This can have several benefits, including weight loss and improved blood sugar control. However, if you suddenly introduce a lot of carbohydrates back into your diet, your body will switch back to using glucose as its primary fuel source, and this can cause a spike in blood sugar levels.
The extent of the blood sugar spike will depend on the type and amount of carbohydrates you consume during your cheat day. If you have a large amount of refined carbohydrates and saturated fats, you may see a more significant spike. Additionally, if you have diabetes or pre-diabetes, a cheat day can be especially risky as it may cause a dangerous rise in blood sugar levels.
It's important to note that having an occasional cheat day on the keto diet won't destroy your progress, and it may even have some psychological benefits. However, if you're doing keto for health reasons, such as managing blood sugar or diabetes, cheating on the diet might not be the best idea.
If you're going to have a cheat day, there are a few things you can do to minimise the impact on your blood sugar:
- Opt for keto-approved cheat meals: Instead of going all-out with high-carb, high-sugar foods, choose keto-friendly substitutes that will curb your cravings without kicking you out of ketosis.
- Have cheat meals, not cheat days: It's easier to stay on top of your overall nutrition and calories if you limit your cheats to meals rather than entire days.
- Plan your cheats: Pick which meals you're going to cheat on in advance and budget your calories and carbs accordingly. This will help you stay within your weekly nutrition goals and prevent weight gain.
- Prioritise certain events or favourite foods: Instead of giving in to random temptations, save your cheats for special occasions or foods that are really worth it to you.
- Pair carbs with protein: When you do have carbs, try to pair them with a source of protein, as this can help to slow the release of glucose into the bloodstream and prevent a sharp spike in blood sugar levels.

Cheat meals can cause keto flu symptoms
The keto diet is a very low-carb, high-fat, and moderate-protein diet. It is considered safe for most people but is associated with some unpleasant side effects. When people start the keto diet, their body adapts to a new diet consisting of very few carbohydrates. This switch to burning fat for energy is called ketosis.
The keto flu is a collection of symptoms experienced by some people when they first start the keto diet. These symptoms can include fatigue, muscle soreness, headaches, and sugar cravings, and they can range from mild to severe. They are caused by the body adapting to a new diet consisting of very few carbohydrates.
When you cheat on a keto diet, you may experience these keto flu symptoms again. This is because your body is transitioning back to burning ketones for energy instead of glucose. The longer you stay out of ketosis, the greater the chance that these negative symptoms will return when you attempt to get back into it.
If you are experiencing keto flu symptoms after cheating on a keto diet, there are some things you can do to ease the symptoms:
- Drink plenty of water to stay hydrated.
- Avoid strenuous exercise. Light activities like walking or yoga may improve symptoms.
- Replace electrolytes by salting your food to taste or eating potassium-rich, keto-friendly foods like leafy greens and avocados.
- Get enough sleep.
- Eat enough fat and carbohydrates. Transitioning to a very low-carb diet can cause you to crave restricted foods, but eating enough fat will help reduce cravings and keep you feeling satisfied.
Cheating on the keto diet may not be a good idea if your goal is to stay in ketosis for reasons other than weight loss. However, if your primary goal is to lose weight, an occasional cheat meal will not destroy your progress as long as you are maintaining calorie control overall.

Frequently asked questions
Breaking keto for a weekend won't ruin your progress, but it will slow it down. If you're doing keto for weight loss, you can still lose weight even if you're not in ketosis, as long as you're maintaining calorie control overall. However, if you're staying in ketosis for reasons other than weight loss, cheating on a ketogenic diet might not be a good idea.
When you break keto and eat a high-carb meal, your body will stop producing ketones and switch back to using glucose as a source of fuel. This will cause a temporary gain in water weight. You might also experience a sugar crash and repeat symptoms of "keto flu" when you resume your keto diet.
It can take anywhere from one day to a week to get back into ketosis, but it usually happens much quicker the second time around. If you've been on keto for more than 3 to 6 weeks, it will be easier to get back into ketosis since your body is already fat-adapted.
If you want to break keto for a weekend without ruining your progress, it's recommended to have a cheat meal instead of a cheat day. This way, you'll consume fewer carbs and it might not even take you out of ketosis. You can also opt for keto-friendly substitutes or splurge on keto-friendly snacks and "cheat foods" that are now widely available in the market.
