The keto diet is a very low-carb, high-fat diet that's 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 keto diet is very strict, you may find yourself tempted by the occasional high-carb food. So, is it okay to have a cheat day on keto?
Cheat meals or days are common strategies for strict diets. The former allows you to break the diet's rules throughout the day, while the latter lets you have a single meal that breaks the rules. The idea of planned cheating is that by allowing yourself short periods of indulgence, you're more likely to stick to the diet over the long term.
However, cheating on the keto diet is far from ideal. That's because this diet relies on your body staying in ketosis. To do so, 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, which are derived from fats—as soon as a sufficient number of carbs are available.
Because 50 grams of carbs is relatively few, a single cheat meal can easily exceed your daily carb allowance and take your body out of ketosis—while 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's also worth noting that it's easy to overeat while cheating, which may sabotage your weight loss efforts and promote unhealthy eating habits.
If you've cheated on keto, you're likely out of ketosis. Once out, you'll need to strictly follow the keto diet to re-enter ketosis. This process takes several days to one week, depending on your carb intake, metabolism, and activity levels.
So, should you include a cheat day in your keto diet plan? According to keto experts, having a cheat day while on keto has more drawbacks than benefits, especially if you go all out on your cheat day and observe it without certain limitations. The keto diet limits or completely eliminates carb consumption, and while that's a difficult feat to achieve in your first few months of observing the keto diet, seasoned proponents say it gets easier over time.
Studies show that carbohydrates, specifically in the form of sugar, have a way of inducing reward and craving that's comparable to addictive drugs—it's difficult to stop once you get going. If you give yourself the luxury of increasing carb intake during your cheat days, you end up strengthening your cravings, making it harder for you to avoid carbs in the future.
Observing the keto diet macros to a T can be a challenge for new keto dieters. But if you stay on it for long enough, you'll find that consuming more fat and protein and fewer carbs starts becoming second nature. When you observe weekly cheat days, however, you add roadblocks to your progress. Nutritionists believe a day of staying off your keto diet macros is enough to stop your momentum and make it difficult for you to bounce back.
In conclusion, while it may be tempting to indulge in a cheat day while following the keto diet, it's important to consider the potential drawbacks. Cheat days can easily break ketosis—the metabolic state that's the hallmark of this diet. If you do choose to include a cheat day in your keto diet plan, it's important to do so in a way that minimizes the negative impacts on your progress.

What You'll Learn
Cheat days can be a reward for your hard work
That being said, if you're determined to stick to your keto diet, there are ways to incorporate cheat days without completely derailing your progress. Here are some tips to help you navigate cheat days while staying on track:
- Opt for keto-approved treats: Instead of going all out on high-carb, sugary treats, look for keto-friendly alternatives. There are plenty of keto-friendly recipes and packaged snacks available that can satisfy your cravings without kicking you out of ketosis.
- Have cheat meals, not cheat days: It's easier to manage your overall nutrition and calories if you limit your cheats to a single meal rather than a whole day. A large cheat meal can add 1,000 or more calories, while a full cheat day will likely undo all your hard work for the week.
- Plan your cheats: Pick which meals you want to cheat on and budget your calories and carbs accordingly. This way, you can indulge without going overboard.
- Make it count: Choose your cheat meals wisely. Prioritize special events or your favourite foods over random temptations. For example, if you know there's a birthday party coming up, plan to enjoy a slice of cake without feeling guilty.
- Space out your cheats: Don't make cheat days a daily occurrence. Space them out generously, whether it's once a week or once a month. The less frequently you cheat, the less likely you are to form bad habits.
- Exercise after cheating: Exercise increases your body's ability to process carbs, helping you get back into ketosis faster. So, if you know you're going to cheat, try to schedule some physical activity for afterwards.
- Get back on track quickly: Don't let a cheat meal turn into a cheat week. The longer you stay off your keto diet, the harder it will be to get back on track. Resume your low-carb keto lifestyle as soon as possible.
Remember, the key to successful cheat days is moderation and planning. As long as you're mindful and don't go overboard, you can enjoy the occasional treat without sabotaging your progress.

Cheat days can teach you moderation
Cheat days can be a great way to teach yourself moderation, especially if you're on a restrictive diet like keto. Here's how:
It teaches you to listen to your body: Cheat days can help you understand your body's signals and cravings better. By allowing yourself to indulge in previously restricted foods, you become more aware of how these foods make you feel physically and mentally. This awareness can help you make more conscious and mindful food choices in the future.
It helps you develop a healthy relationship with food: Restrictive diets can sometimes lead to an unhealthy relationship with food, where certain foods are labelled as "good" or "bad." Cheat days can help break this mindset by showing you that it's okay to enjoy a variety of foods in moderation. It can also reduce the risk of developing disordered eating behaviours, such as binge eating, by providing a structured way to include treats in your diet.
It keeps you motivated: Sticking to a restrictive diet like keto can be challenging, and cheat days can provide a much-needed mental break. They give you something to look forward to and help you stay motivated to continue with your diet. This can be especially beneficial if you're in it for the long haul.
It teaches you flexibility and balance: Cheat days can teach you how to incorporate treats into your diet in a flexible and balanced way. By planning your cheat meals or days in advance, you learn how to make adjustments to your regular diet to accommodate them. This skill can be valuable for maintaining a healthy diet in the long run.
It helps you develop self-control: Cheat days can be a test of your self-control. By allowing yourself to indulge in moderation, you learn how to say "no" to excessive consumption and how to stop eating when you're satisfied. This skill can be beneficial for maintaining a healthy weight and preventing overeating.
However, it's important to remember that cheat days should be occasional and not too frequent, as they can hinder your progress if overdone. Additionally, it's best to make smart choices during your cheat meals, such as opting for high-quality carbs and avoiding excessive sugar. This will help minimise the negative impacts on your health and weight loss goals.

Cheat days can be a welcomed break from your diet
If your goal is to stay in ketosis, cheat days are not recommended. Ketosis is a metabolic state in which your body burns fat as its primary source of energy instead of carbs. To stay in ketosis, you need to eat fewer than 50 grams of carbs per day. A single cheat meal can easily exceed this daily carb allowance and take your body out of ketosis, while a cheat day is almost certain to surpass 50 grams of carbs. It can then take several days to 1 week to get back into ketosis, depending on your carb intake, metabolism, and activity levels.
If your primary goal is to lose weight, an occasional cheat day is not going to destroy your progress. Ketosis is likely not the main reason you are losing weight—calorie control is. So, as long as you aren't going overboard with cheat days and are maintaining overall calorie control, having some extra carbs won't undo all your hard work. However, if you're not careful, cheat days can lead to overeating, which may sabotage your weight loss efforts.
If you do decide to have a cheat day, it's best to have a cheat meal rather than a full cheat day. This way, you're more likely to stay within your overall nutrition and calorie goals for the week. It's also a good idea to plan your cheats in advance and space them out. This way, you can ensure they're worth it by prioritising certain events or favourite foods over random temptations that will always be there.
