The ketogenic diet is a popular weight-loss plan that involves depriving the body of carbohydrates, causing it to enter a state of ketosis, where it burns fat for energy instead. This state can be disrupted by consuming sugary or starchy foods, which provide the body with its original fuel source: carbohydrates. While occasional treats are unlikely to derail long-term weight loss goals, consuming sugar while in ketosis can cause gastrointestinal distress and other side effects, such as nausea, headache, and brain fog, commonly referred to as the keto flu or a sugar hangover. These negative consequences have led some individuals to question whether consuming sugar while on the keto diet can make them sick.
| Characteristics | Values |
|---|---|
| Feeling sick due to sugar on keto | Feeling sick is common due to the body's inability to digest high-carb foods after being in ketosis for a while. Symptoms include nausea, headache, brain fog, stomach ache, bloating, and other digestive issues. |
| Impact on ketosis | Eating sugar can take the body out of ketosis, the fat-burning state, and switch it back to burning carbohydrates. |
| Occasional treats | As long as high-carb foods are not consumed regularly, an occasional treat should not significantly impact long-term weight loss or maintenance goals. |
| Returning to ketosis | Returning to a low-carb diet after a slip-up can help get back into ketosis fairly quickly. |

What You'll Learn
Sugar can cause gastrointestinal distress
While on a keto diet, consuming sugar can cause gastrointestinal distress. This is because when your body is deprived of carbohydrates, it enters a state called ketosis, where it burns fat instead of carbohydrates for energy. However, consuming sugar or carbohydrates can take you out of this fat-burning state.
When your body is in ketosis for a prolonged period, it may no longer be able to digest high-carbohydrate foods in the same way it used to. As a result, you may experience gastrointestinal distress, such as stomach aches, nausea, bloating, and other digestive issues. This is because a high intake of sugar disrupts the intestinal barrier, increasing gut permeability and causing a disturbance in mucosal immunity, making you more susceptible to infections.
Additionally, for people with diabetes, high blood sugar levels can lead to gastroparesis, a condition where the stomach does not empty properly due to nerve damage. This can cause bloating, discomfort, or pain after eating even small amounts of food. Managing blood sugar levels is crucial to preventing or delaying gastroparesis and its associated health risks.
The occasional sugary treat while on a keto diet may not cause significant issues, but it is essential to maintain a low-carb intake to remain in ketosis. Overall, sugar overconsumption is linked to various health issues, including diabetes, cardiovascular diseases, and cancer, highlighting the importance of moderation in sugar intake.

Eating sugar can throw your body out of ketosis
The ketogenic diet is a low-carbohydrate method of eating that involves putting the body into a state of ketosis, where it burns fat instead of carbohydrates for energy. This state of ketosis can be disrupted by the consumption of sugar and carbohydrates, which can cause the body to switch back to burning carbs for fuel.
The amount of carbohydrates recommended on a keto diet is between 20 and 50 grams per day, which equates to around 5 to 10 percent of daily calories. Eating sugar can quickly exceed this limit, as it is often combined with other high-carbohydrate ingredients. This can cause a spike in blood sugar levels, triggering the body to start burning glucose instead of fat. As a result, the body falls out of ketosis, and it may take several days to re-enter this state.
Consuming sugar while in ketosis can also cause gastrointestinal distress, as the body may no longer be equipped to digest high-carbohydrate foods efficiently. Additionally, it may trigger a psychological setback, as some people find that staying low-carb helps them to curb sugar cravings.
It is important to note that not all sugars are created equal, and some natural sweeteners like Stevia, Erythritol, and AlluMonk are keto-friendly and can be consumed in moderation. However, it is always advisable to check labels and measure intake, as even natural foods can contain hidden sugars.

You may experience keto flu symptoms
Eating sugar while on a keto diet can cause some unpleasant side effects, including gastrointestinal distress. This is because your body may no longer be equipped to digest high-carbohydrate foods in the same way it used to. As a result, you may experience symptoms such as stomach ache, nausea, bloating, and other digestive issues.
These side effects are often referred to as "keto flu" and can occur when you fall out of ketosis and your body switches back to burning carbs for energy. Ketosis is a state where your body burns fat instead of carbohydrates for energy, achieved by depriving your body of carbs. The keto diet recommends keeping your carbohydrate and sugar intake to a minimum, typically between 20 and 50 grams of carbohydrates per day.
Eating something very sugary or starchy can quickly take you out of ketosis, as your body falls back on its original fuel source: carbs. While it can take several days to initially reach ketosis, falling out of it doesn't mean starting from scratch. David Bridges, a PhD assistant professor of nutritional sciences, notes that it doesn't take as long to get back into ketosis after a slip-up.
However, the occasional sugary treat won't derail your long-term weight loss goals as long as you don't make it a regular occurrence. If you do find yourself experiencing keto flu symptoms, staying hydrated and consuming electrolytes can help alleviate these side effects.

Sugar can cause a psychological setback
Eating sugar while on a keto diet can cause a psychological setback. The keto diet requires a lot of focus and dedication, as it involves keeping your carbohydrate and sugar intake to a minimum. When you deprive your body of carbs, you enter a state called ketosis, where your body burns fat instead of carbohydrates for energy. However, consuming sugar can quickly take you out of this fat-burning state.
The occasional sugary treat can throw your body out of ketosis and make you feel unwell physically, but it can also have psychological implications. When you maintain a low-carb diet, your body adjusts to not craving sugar. Introducing sugar after a period of abstinence can, therefore, be a setback, as it may reignite sugar cravings and make it more challenging to stick to your keto plan.
In addition, there is a growing body of evidence that suggests a link between sugar consumption and mental health issues. High sugar consumption has been associated with common mental disorders, and it is suggested that sugar intake can adversely affect long-term psychological health. This includes an increased risk of mood disorders such as depression and anxiety. Sugar consumption has also been linked to cognitive impairments and negative neuroplasticity, which can alter emotional states and behaviours.
Men, in particular, are at a higher risk of adverse mental health conditions related to sugar consumption. Studies indicate that men who consume more than 40 grams of sugar per day are highly likely to be diagnosed with depression within a few years. Furthermore, sugar can be highly addictive, and this addiction can lead to or exacerbate mental health issues.
While the physical side effects of consuming sugar while in ketosis are often temporary, the psychological implications can be more challenging to manage. It is important to be mindful of the potential risks of sugar consumption and to consider the impact on your mental health, especially if you are prone to addictive behaviours or have experienced mental health issues.

Sugar can lead to dehydration
Eating sugar while on a keto diet can cause gastrointestinal distress, including stomach aches, nausea, bloating, and other digestive issues. It can also cause a setback in your psychological progress. However, this is not the same as being physically sick.
The movement of water in and out of our cells is called osmosis. When there is a higher concentration of sugar molecules in the blood, water moves to dilute and reduce the concentration of sugar molecules. This movement of water results in a loss of water from cells, causing dehydration at the cellular level.
People with diabetes may experience severe spikes in blood sugar levels due to their inability to produce or respond to insulin. Insulin is a hormone that allows the body's cells to absorb sugar from the bloodstream and use it for energy. When the body does not use insulin properly, sugar accumulates in the bloodstream, causing an increase in urination and leading to dehydration.
To prevent dehydration caused by sugar consumption, it is important to maintain a balanced diet and stay hydrated. While water does not directly lower blood sugar levels, it is still beneficial for people with diabetes to drink water as it helps flush out excess glucose without raising blood glucose levels.
