Carb Overload On Keto: What's The Impact?

The Ketogenic Diet is a low-carbohydrate method of eating that helps people with diabetes, epilepsy, autoimmune disorders, acid reflux, inflammation, hormonal imbalances, and other issues. The diet recommends staying under 20g of carbs per day to stay in ketosis, but what happens if you accidentally overload on carbs? While it depends on the person, exceeding the recommended amount of carbs can result in being kicked out of ketosis, which can cause bloating, stomach cramps, tiredness, and water weight gain. It can also lead to carb cravings, making it challenging to get back on track. The time it takes to return to ketosis depends on the individual, but it typically takes about a day of restricting net carbs.

You will no longer be in ketosis

If you consume too many carbs, you will no longer be in ketosis. The number of carbs that is "too many" differs from person to person, but it is generally agreed that up to 20g of carbs per day is safe for most people. Eating more than this will take you out of ketosis, and it will take about a day of restricting carbs to get back into it.

When you are no longer in ketosis, you will be burning glucose instead of ketones. This can slow down weight loss or cause you to retain water and regain water weight. It can also lead to a variety of physical symptoms, such as bloating, stomach cramps, tiredness, headaches, lethargy, neck and shoulder tension, and aches.

The longer you have been on the keto diet, the more likely you are to experience physical symptoms when you exit ketosis. If you have been on the diet for a while, you may also experience a return of carb cravings, which can be a slippery slope back into a high-carb diet.

If you are still in the initial stages of the keto diet, exiting ketosis can also delay your body's adaptation to the diet.

You may experience bloating, stomach cramps, and fatigue

Overloading on carbs while on the keto diet can lead to various physical discomforts, including bloating, stomach cramps, and fatigue. These symptoms can be unpleasant and may leave you feeling unwell and tired.

Bloating is a common issue when consuming excess carbohydrates, especially if you have been restricting your carb intake while on keto. This is because your body has become accustomed to a low-carb diet, and suddenly introducing a higher amount can cause a shift in your digestive system, leading to that full and gassy feeling in your stomach.

Stomach cramps may accompany the bloating, and they can range from mild discomfort to more intense pain. These cramps are often a result of your body trying to adjust to the sudden increase in carbohydrates, which can be challenging for your digestive system.

Additionally, you may experience fatigue or a lack of energy. This is because your body is now burning glucose from the carbohydrates instead of ketones, which is the primary source of energy while in ketosis. This shift in energy sources can result in a decrease in overall energy levels, leaving you feeling tired and lethargic.

The extent of these symptoms can vary depending on individual factors, such as the duration of your keto diet and your body's unique response to carbohydrate intake. However, it is important to listen to your body and be mindful of any discomfort or changes you experience.

To alleviate these issues, it is recommended to gradually increase your carbohydrate intake and be mindful of your body's response. While it is normal to experience some adjustments when introducing new foods, ensuring that you are not causing unnecessary discomfort is essential. Additionally, staying hydrated, engaging in light physical activity, and allowing your body time to rest can help ease these symptoms.

Weight loss may slow down or you may gain water weight

Overloading on carbs while on a keto diet can lead to a slower weight loss or even water weight gain. This is because when you consume too many carbs, your body exits the state of ketosis and starts burning glucose instead of ketones for energy. The excess glucose that is not used up gets stored as glycogen in your liver and muscle cells, and each gram of glycogen is stored with about three grams of water. This can lead to a gain in water weight, which may be reflected on the scale as a slower weight loss or even a slight increase in weight.

The amount of carbs that will kick you out of ketosis varies from person to person, but generally staying under 20 grams of carbs per day is recommended to ensure ketosis. However, some people may still be in ketosis at 30 or even 50 grams of carbs per day. If you exceed your carb limit, it will take about 24 hours of being under your carb limit again to get back into ketosis.

The good news is that even if you do kick yourself out of ketosis by eating too many carbs, as long as you stay under your calorie limit for the day, you will still lose the same amount of fat. The only difference is that you might gain some water weight, but this will be lost again once you get back into ketosis without affecting your fat loss.

It's important to note that giving in to carb cravings doesn't have to mean falling off the keto wagon completely. A single meal with extra carbs doesn't have to turn into days, weeks, or months off the keto plan. The key is to enjoy those carbs that are worth it to you and then get right back on track. This way, you can prevent your body from feeling terrible, delay your adaptation to ketosis, and avoid overeating.

Additionally, the longer you've been on the keto diet, the more leeway you might have with carbs. After being keto-adapted for about 6-8 weeks, your body may be able to handle the excess glucose by shunting it into your glycogen stores instead of immediately switching back into glucose-burning mode. However, if you continue to overload on carbs for multiple days in a row, you might have to start the process of getting into ketosis all over again.

You may experience constipation and gastrointestinal discomfort

Overloading on carbs while on the keto diet can lead to constipation and gastrointestinal discomfort. This is due to a lack of fiber in the diet, which is essential for maintaining regular bowel movements and a healthy gut microbiome.

Constipation can occur when there is an insufficient intake of fiber, which is often the case when following a low-carbohydrate diet like keto. Fiber adds bulk to stool and helps to move it through the intestines, so a lack of fiber can result in hard, dry stools that are difficult to pass. This can lead to feelings of bloating and discomfort, as well as a decreased frequency of bowel movements.

Gastrointestinal discomfort can also arise from overloading on carbs while on keto. This can include symptoms such as indigestion, bloating, and cramps. These symptoms may be due to the body's difficulty in digesting a large amount of carbohydrates, particularly if the diet has been low in carbs for some time. The sudden increase in carb intake can cause a shift in the balance of bacteria in the gut, leading to digestive issues.

Additionally, the type of carbohydrates consumed can also play a role in gastrointestinal discomfort. Refined carbs, such as white bread and pasta, are low in fiber and can contribute to constipation and gut issues. On the other hand, whole grain carbohydrates, such as farro and barley, are higher in fiber and can help promote regularity and a healthy gut.

It is important to note that everyone's experience with the keto diet may vary, and some individuals may be more sensitive to carbohydrate overload than others. However, ensuring adequate fiber intake and choosing high-fiber carbohydrate sources can help mitigate the risk of constipation and gastrointestinal discomfort while on the keto diet.

You may feel a food coma-like sluggishness

If you overload on carbs while on the keto diet, you may experience a food coma-like sluggishness. This is because your body will be burning glucose instead of ketones, which can result in a decrease in energy levels. The feeling of sluggishness may be more pronounced if you are engaging in shorter training sessions or races, as carb-loading is typically recommended for long-distance biking and running (over 90 minutes).

The amount of carbs that will cause this sluggishness can vary from person to person, but it's generally recommended to stay under 20 grams of carbs per day to maintain ketosis. Going over this limit can also lead to other physical discomforts such as bloating, stomach cramps, and headaches.

It's important to note that the keto diet is a low-carbohydrate method of eating, and overloading on carbs can kick you out of ketosis. Ketosis is a state where your body burns fat instead of glucose for energy. Staying in ketosis is important for those following the keto diet to achieve their desired results, which may include weight loss and improved health.

If you accidentally consume too many carbs while on the keto diet, it's recommended to get back on track as soon as possible. This may involve compensating for the slip-up by eating fewer calories or exercising to burn off the extra carbs. It's also crucial to listen to your body and adjust your meal plan accordingly to find the optimal amount of carbs your body needs.

To avoid overloading on carbs, it's recommended to favour whole-grain carbohydrates and include more complex carbohydrates in your diet, such as pasta made with lentils, chickpeas, or edamame. Additionally, it's important to be mindful of hidden carbs in cooked meals or ingredients, as they can quickly add up and push you over your carb limit.
