Cheat days have become a popular concept in diet culture, especially on social media. The idea is that a dieter can 'cheat' for one day a week, eating whatever they want, as long as they stick to their diet for the remaining days. The two main motivations for cheat days are that they boost your metabolism, causing you to burn more calories, and that they help dieters stick to their diet by keeping leptin levels up, reducing feelings of hunger. However, there is little rigorous scientific research to support these theories, and cheat days can cause disordered eating behaviours, especially in adolescents. Nutritionists recommend satisfying a single craving instead of devoting an entire day to indulgences, and indulging in your cravings on the day of an intense workout.

What You'll Learn

Cheat days may increase your metabolism in the short term
Cheat days have been linked to increased metabolism in the short term. This is due to the body's production of leptin, a hormone that helps maintain energy balance and suppress feelings of hunger. When you restrict your calorie intake, your body eventually adapts and lowers your metabolism to match your new intake. However, cheat days may provide a temporary boost to your metabolism, causing you to burn more calories.
While this theory suggests a potential benefit of cheat days, it is important to consider the limited scientific research supporting it. Additionally, any short-term metabolic increase may be outweighed by the potential harm caused by cheat days, including the promotion of an unhealthy relationship with food and the risk of disordered eating behaviours.
Furthermore, the effectiveness of cheat days varies across individuals, and some people may struggle to regulate their eating behaviours effectively. As such, it is essential to approach cheat days with caution and be mindful of portion sizes and overall dietary habits to maintain a balanced and healthy lifestyle.
Although cheat days may provide a psychological boost and help with adherence to a diet, they should be carefully planned and managed to avoid potential negative consequences. It is recommended to view them as occasional indulgences rather than an integral part of a healthy diet, as a healthy diet is characterised by balance and moderation.

They can help you stick to your diet
Cheat meals or cheat days have become a popular strategy for people trying to lose weight or maintain a healthy lifestyle. The idea is that by allowing yourself to indulge in foods that are not usually permitted on your diet, you will be more likely to stick to your prescribed diet for the rest of the time.
There are two main motivations for cheat meals. The first is the theory that they boost your metabolism, causing you to burn more calories. When you restrict your calorie intake, your body eventually adapts and lowers your metabolism, but cheat days may prevent this. The second is that cheat days can help keep your leptin levels up. Leptin is the hormone responsible for suppressing feelings of hunger, and its levels fall when you diet, making it harder to resist eating.
Cheat meals can be a useful psychological tool, giving you something to look forward to and helping you stick to your diet. However, it is important to remember that not everyone will respond to the same strategies, and the best diet plan is the one you can stick to. For some people, cheat days may not be appropriate, and a different approach may be more suitable. It is also important to be mindful of portion sizes and not to overdo it on cheat days, as this could undo your progress.
Nutritionists recommend satisfying a single craving instead of devoting an entire day to indulgences. The frequency of cheat meals should depend on your health goals. If you plan to consume more calories, do it on a day you can burn them off, and try to choose a meal that is high in protein to rebuild muscle mass and satiate hunger.
Overall, cheat meals can be a helpful way to stick to your diet, but they should be planned and not spur-of-the-moment. By incorporating them into your diet in a calculated and controlled manner, you can enjoy the foods you love while still maintaining your weight goals.

They can be a reflection of a restrictive diet
Cheat days or meals have become increasingly popular in Western diet and fitness culture, especially through social media platforms. The idea is that by allowing yourself brief periods of indulgence, you will be more likely to stick to your prescribed diet the majority of the time. However, wanting a cheat day can also be a reflection of a restrictive and unenjoyable diet.
The more you restrict some foods, the more you will think about them. As Emma Randall, a mindful eating consultant, explains, "will-power is a bit like a phone battery; it tends to run out by the end of the day". Instead of a restrictive diet with cheat days, Randall suggests a moderate weight-loss diet that doesn't leave you craving cheat days. Such a diet is likely to be more beneficial for physical and mental health.
Furthermore, cheat days can open the door to a wide range of disordered eating behaviours. A 2022 article in the Journal of Eating Disorders found that, among adolescents, eating cheat meals is linked to greater eating disorder behaviours and psychopathology, including binge-eating episodes. Cheat days can also reinforce some outdated ways of thinking about food and weight loss. As Taylor, a health expert, explains, "having a cheat day implies that a healthy diet is all-or-nothing—that you're either 'off the plan' or 'on the plan'".
Instead of devoting an entire day to indulgences, nutritionists recommend satisfying a single craving. Remember that the frequency of your cheat meals or days should depend on how close you are to your health goals. If you plan to consume a larger amount of calories, try to do it on a day you can burn them off, ideally after an intense workout.

They may undo your progress
Cheat days or meals have become increasingly popular in Western diet and fitness culture, especially through social media. The idea is that by allowing yourself brief periods of indulgence, you will be more likely to stick to your prescribed diet the majority of the time. However, cheat days may undo your progress in several ways.
Firstly, it is easy to go overboard on cheat days. Cheat days can promote an unhealthy attitude towards food and an all-or-nothing mindset, implying that a healthy diet is either 'on the plan' or 'off the plan'. This adds moral baggage to every decision you make about food and encourages a black-and-white, extreme approach to dieting. As a result, you may end up eating more calories than you should, undoing your prior weight loss efforts.
Secondly, cheat days may not provide the metabolic boost you need to make a significant difference in your weight loss journey. While there is evidence that cheat days may increase your metabolism in the very short term, this boost does not last long enough to have a significant impact. Instead, cheat day calories can add up quickly and bring your weight loss progress to a halt or even reverse it.
Thirdly, cheat days can reinforce outdated ways of thinking about food and weight loss. Labelling certain foods as "cheat meals" or "treats" implies that some foods are good and others are bad. This mindset can lead to a restrictive and unenjoyable diet, which may not be sustainable in the long term.
Finally, cheat days can be risky for people who are sensitive to salt, saturated fat, or added sugars. Dietitian Kathy McManus notes that she has seen people's diets affect their blood pressure or cholesterol in as little as a few weeks after splurging. Therefore, while an occasional cheat meal may not be harmful for generally healthy people, it could be risky for those with certain health conditions.
In conclusion, while cheat days may work for some people, they may undo the progress of others. It is important to be mindful of portion sizes and maintain a balanced approach to eating, where not every food has to enhance your health but also does not detract from it.

They can cause anxiety
Cheat days or meals have become increasingly popular in Western diet and fitness culture, especially through social media platforms. The idea is that by allowing yourself brief periods of indulgence, you will be more likely to stick to your diet for the remaining period. However, cheat days can cause anxiety.
Referring to any foods as a 'cheat' may cause anxiety due to its negative connotations. The term 'cheat' adds moral baggage to every decision you make about food and encourages a black-and-white, extreme approach to dieting. This can lead to an unhealthy mindset and attitude towards food, promoting the idea that a healthy diet is all-or-nothing. This mindset can cause anxiety about 'cheating' and can make it difficult to maintain a balanced and healthy diet.
Furthermore, the idea of 'cheat days' can cause anxiety about overindulging and undoing progress. Some people may feel anxious about their cheat meal and analyse it to "get it right", which can lead to disordered eating behaviours. The concept of 'cheat days' can also cause social anxiety, as it may be difficult to stick to a diet at a special event where cake and alcohol are prevalent.
Instead of having 'cheat days', it is recommended to follow a healthy diet on most days and allow yourself the pleasure of occasionally indulging. This can be done through the 90-10 rule, where you eat a healthy diet 90% of the time and indulge 10% of the time. However, it is important not to abuse this rule and to be mindful of portion sizes when indulging.

It is also important to maintain a healthy eating plan on most days and not bargain with yourself. Remember that not every food needs to be labelled as "good" or "bad", and a healthy diet is a balanced one.
