The ketogenic diet is a popular, high-fat, low-carb diet that can be challenging to stick to. Many people are tempted to have a cheat day where they eat high-carb foods, but is this a good idea?
There are several disadvantages to having a cheat day on the keto diet. Firstly, it can take you out of ketosis, the metabolic state where your body burns fat for energy instead of glucose. Secondly, cheating affects your fat adaptation, as your body needs to make changes to transition to a fat-burning state, and a sudden dose of glucose can prevent this. Thirdly, cheat days can cause a spike in blood sugar, which is dangerous for people with type 2 diabetes or cardiovascular issues.
However, some people find that having a planned cheat day helps them stick to their diet in the long term, and there are ways to implement a cheat day without undoing all your progress. For example, you could follow a cyclical ketogenic diet, which involves eating a strict keto diet for 5-6 days and then having 1-2 days of higher carb consumption. You could also try keto-friendly alternatives to your favourite treats, such as keto pizza or keto cookies.
Ultimately, it's up to you whether you have a cheat day on the keto diet, but be aware of the potential side effects and try to make conscious decisions about what you eat.

What You'll Learn
Cheat days can kick you out of ketosis
The keto diet is a high-fat, very low-carb diet. When following a ketogenic diet, you restrict carbs to under 50 grams per day, and your body must burn fat for energy instead of glucose, or blood sugar, in a process known as ketosis.
The problem with cheat days is that they often sound like a comforting plan B if things don't work out. This means you're not going all in, and you may not be getting the results you want. Cheat days on the keto diet will usually postpone your weight loss efforts.
The keto diet is pretty simple: cut out carbs and eat lots of fats. But unlike many other diets, the keto diet does not have much room for flexibility. This is because of the ketone bodies that you need to be in ketosis and burn fat. It takes time and effort to get into and stay in ketosis, and every time you cheat, you likely reset your progress and need to start again. This back-and-forth hopping will stretch the weight loss process and it will take more effort to burn fat.
The carbs you eat will stop your ketone production until they are burnt out or stored away. Achieving ketosis is not complicated, but it takes time and effort. You spend so much time and effort turning your body into a crazy fat-burning state, and when you are kicked out of ketosis, you need to start that process all over again.
If you are keto-adapted and well deep in ketosis, a one-time cheat meal probably won't spike your blood sugar as high as you would expect. However, if you are not keto-adapted and eat a pizza, for example, your blood sugar will skyrocket.
Cheat meals, as well as cheat days, almost always lead to immediate weight gain. Carbohydrates will put your body back into fat-storing mode, and you will swell up. With carbs, there also comes hunger and more cravings, which will make you eat more.
Cheating will also affect your fat adaptation. Getting into ketosis is no simple task for your body. It has to make changes like altering hormones and increasing enzyme production to optimize the fat-burning state. Having cheat days can prevent your body from continuing this process long enough to stay in ketosis. If you are not maintaining ketosis, your body will not start the fat-burning process.
If you are following the keto diet for health reasons, it's important to know that eating cheat meals can cause blood sugar levels to spike. Plus, since your glucose tolerance has depleted on keto, you will likely experience a nasty sugar hit.
In summary, cheat days can kick you out of ketosis and affect your weight loss efforts. They can also lead to weight gain, increased hunger and cravings, and negatively impact your fat adaptation and blood sugar levels.

One cheat day can damage blood vessels
The ketogenic, or keto, diet is a popular high-fat, low-carbohydrate diet that has been shown to be effective for weight loss and the management of diseases such as Type 2 diabetes. However, new research suggests that a single "cheat day" while on the keto diet can undo some of the positive impacts of the diet and lead to damaged blood vessels.
The keto diet involves eating foods that are rich in fats, moderate in protein, and very low in carbohydrates. This causes the body to go into a state of ketosis, where it burns fat instead of its preferred fuel source, glucose. During ketosis, the body's chemistry changes, and it begins to aggressively burn its fat stores, leading to weight loss and improved symptoms of diseases such as Type 2 diabetes.
Despite the benefits of the keto diet, it can be challenging for people to follow the diet strictly without indulging in a "cheat day". Researchers at the University of British Columbia in Okanagan, Canada (UBCO) conducted a study to investigate the effects of a "cheat day" on the keto diet. The study included nine healthy young males who consumed a 75-gram glucose drink before and after a 7-day high-fat, low-carbohydrate diet similar to the keto diet.
The researchers found biomarkers in the blood that suggested the blood vessel walls were being damaged by the sudden spike in glucose. The results were alarming, as the participants' blood vessel health after consuming the glucose drink resembled that of individuals with poor cardiovascular health. The most likely culprit for the damage is the body's own metabolic response to excess blood sugar, which causes blood vessel cells to shed and possibly die.
While the study had a small sample size and more research is needed to verify the findings, the results suggest that people on the keto diet may undo some of the positive impacts of the diet if they suddenly reintroduce glucose. This is especially concerning for those who are at a higher risk for cardiovascular disease. Therefore, those on the keto diet should be cautious about having a "cheat day" and consider the potential risks involved.

Cheat days can lead to immediate weight gain
Cheat days are a common theme in many diets, and the ketogenic diet is no exception. However, incorporating a cheat day into your keto diet can have several negative consequences, one of which is immediate weight gain.
Firstly, a sudden spike in glucose intake from cheat days can cause your body to go back into fat-storing mode. When you consume a high amount of carbohydrates, your body prioritises burning these carbohydrates for energy instead of burning fat. This can lead to a halt in your weight loss progress or even reverse it, resulting in immediate weight gain.
Secondly, carbohydrates can increase your hunger and cravings, leading to a higher calorie intake. The increased hunger and cravings induced by cheat days can cause you to consume more calories than you would typically eat while on a keto diet. This excess calorie intake can contribute to weight gain, especially if the cheat day involves binge eating or consuming thousands of extra calories.
Additionally, the water weight associated with high-carbohydrate diets can also lead to immediate weight gain. When you increase your carbohydrate intake, your body retains more water, which is reflected on the scales. This water weight gain is temporary and will be lost again once you return to a low-carbohydrate diet.
Cheat days can also have other negative side effects, such as damaging your blood vessels and increasing the risk of cardiovascular disease. Therefore, it is important to carefully consider the potential consequences before deciding to incorporate a cheat day into your keto diet.

Cheat days cause hunger and cravings
Cheat days are a common theme in many diets, and the ketogenic diet is no exception. However, incorporating a cheat day into your keto diet can have some negative consequences.
Firstly, it is important to understand the difference between cravings and hunger. When a person eats, hunger is typically satisfied. However, when you feed a craving, it tends to become stronger. This is an important distinction, as cravings, rather than hunger, are a major goal to eliminate on the ketogenic diet.
Introducing a cheat day into your keto diet can invite hunger and cravings back into your life. This is because cheat days often involve consuming many carbohydrates, which can lead to hunger and cravings, causing you to eat more. In addition, cheat days can lead to immediate weight gain, as the body returns to fat-storing mode, and the water weight associated with high-carb diets comes back.
Cheat days can also have a negative impact on your blood vessel health. Research from the University of British Columbia Okanagan campus found that a single 75-gram dose of glucose (equivalent to a large bottle of soda or a plate of fries) while on a keto diet can lead to damaged blood vessels. This is due to the body's metabolic response to excess blood sugar, which causes blood vessel cells to shed and possibly die. As a result, those on a keto diet may be undoing some of the positive impacts of the diet on their blood vessels if they suddenly reintroduce a high amount of glucose.
Therefore, if you are considering incorporating a cheat day into your keto diet, it is important to be aware of the potential consequences. Cheat days can cause hunger and cravings, leading to a vicious cycle of restricting and binging. They can also negatively impact your weight loss progress and blood vessel health. It may be more beneficial to create a flexible diet that allows for foods you enjoy in moderation, rather than restricting yourself to the point of needing a cheat day.

Cheat days can affect your fat adaption
Cheat days can have a negative impact on your fat adaption. The keto diet is a high-fat, very low-carb diet that puts your body into a state of ketosis, where it burns fat for energy instead of glucose. During ketosis, your body undergoes changes to transition to a fat-burning state, such as altering hormones and increasing enzyme production.
However, introducing a sudden spike of glucose to your body through a cheat day can disrupt this process and prevent your body from becoming fat-adapted. This is because the carbs you eat will stop your ketone production until they are burnt out or stored away. As a result, you may need to start the process of getting into ketosis all over again, which can be time-consuming and challenging.
Additionally, cheat days can lead to immediate weight gain as carbohydrates put your body back into fat-storing mode. They can also cause hunger and cravings, as carbs increase your appetite. This can trigger a downward spiral of overeating and emotional binge eating, which can be challenging to recover from.
Therefore, it is generally recommended to avoid cheat days on the keto diet to maintain ketosis and continue making progress toward your weight loss and health goals.
