Carb Refeeding On Keto: How Often Is Optimal?

The cyclical ketogenic diet involves adhering to a standard ketogenic diet protocol 5–6 days per week, followed by 1–2 days of higher carb consumption. These higher-carb days are often referred to as refeeding days and are meant to replenish your body's depleted glucose reserves. Carb refeeding is not recommended for individuals on a very low-carbohydrate or ketogenic diet for health reasons, such as supportive cancer treatment. For those who are doing keto for weight loss, it is best to stick to the keto diet as much as possible since your body will become fat-adapted and won't need to refuel.

Carb refeeding is meant to replenish your body's depleted glucose reserves

The ketogenic diet is a high-fat, very low-carb diet. When carb intake is drastically reduced, your body must burn fat for energy instead of glucose or blood sugar, in a process known as ketosis. While in ketosis, your body uses ketones—byproducts of fat breakdown produced by your liver—as an alternative energy source.

The cyclical ketogenic diet is popular among those seeking muscle growth and improved exercise performance. Carb refeeding can help break a weight loss stall, improve hormonal balance, enhance muscle growth, and increase energy expenditure and leptin concentration. It can also decrease keto-related side effects, such as constipation, and make the keto diet easier to stick to in the long run.

However, it is important to note that carb refeeding is not for everyone. It is recommended that you only consider doing carb refeeds once your body has adapted to burning fat as its primary fuel source, which usually occurs after at least 4–6 weeks of a ketogenic diet. Additionally, carb refeeding may awaken your carb cravings, so it is crucial to be mindful of your calorie consumption and stick to your plan.

It can help increase muscle growth and improve exercise performance

Carb refeeding, or carb loading, is a period of time, usually a day, where you consume more carbs than usual. This is done intentionally and can be an effective strategy for minimising the negative hormonal or metabolic effects of long-term low-carbohydrate intake.

Carb refeeding can help increase muscle growth and improve exercise performance in a few ways:

Firstly, it can help to replenish glycogen stores, which will enhance your performance in the following days, allowing you to train harder and boost muscle growth. Carbohydrates provide fuel for the muscles in the form of glycogen, and long-term low-carb dieting can lead to depleted glycogen in the muscles and liver, hindering high-intensity exercise performance.

Secondly, carb refeeding can help to raise insulin levels, which can promote muscle growth. Insulin regulates muscle growth by allowing amino acids and glucose into muscle cells, increasing protein synthesis and decreasing protein breakdown in muscle tissue.

Thirdly, carb refeeding can help to balance insulin sensitivity. Insulin resistance can occur when the body does not respond properly to insulin, increasing the risk for diseases such as metabolic syndrome, type II diabetes, and heart disease. Chronically low insulin levels, which can occur on a very low-carb diet, can cause cells to become resistant to insulin signalling. Therefore, carb refeeding can help to optimise insulin sensitivity and reduce the risk of disease.

Finally, carb refeeding can boost leptin levels, which can enhance athletic performance and recovery. Leptin is a hormone released by fat cells that communicates to the brain how much stored energy is available. Low leptin levels can lead to food cravings, mood swings, decreased energy, and stalled weight loss efforts. By increasing carb intake and boosting leptin levels, these negative symptoms can be alleviated, leading to improved exercise performance and recovery.

In summary, carb refeeding on a keto diet can be beneficial for increasing muscle growth and improving exercise performance by optimising glycogen stores, insulin levels, insulin sensitivity, and leptin levels.

It can be done once a week or once a month or every few months

Carb refeeding, or carb loading, is a period of time where you consume more carbohydrates than usual. This is done intentionally and the purpose is to kick your body out of ketosis. Carb ups can help break a weight-loss stall, improve hormonal balance, enhance muscle growth, and increase energy expenditure and leptin concentration.

If you are doing the keto diet for weight loss, you should try to stay in ketosis as much as you can as your body will become fat-adapted and won't need to "refuel". However, if you are doing the keto diet alongside intense workouts, you may want to consider carb refeeding once a week or once a month or every few months. This is because, after a few months, you might notice some side effects such as temporary hair loss, general fatigue, unstable moods, and constipation. By having a carb-refeed day, you will be able to increase your fiber intake and this will make the keto diet easier to stick to in the long term.

If you are going to do a carb-refeed day, you should still be careful about what you eat. While you will have more flexibility, you should try to stick to whole foods that have a lower glycemic index. This will give you the best results and will provoke fewer cravings overall. Some healthy carb options include carrots, sweet potatoes, black beans, quinoa, apples, bananas, and oatmeal.

It is important to remember that carb refeeding might not be for everyone. You need to understand your body and your goals. If you are a beginner, this is not recommended.

Carb refeeding is not recommended for beginners

Carb refeeding, or carb loading, is a period of time, usually one day, where you consume more carbohydrates than usual. This practice is not recommended for beginners.

Firstly, it is important to understand your body and your goals. Carb refeeding will kick your body out of ketosis, which is the purpose of this practice. However, if you are new to the keto diet, it is best to get used to what it feels like to be in ketosis before purposefully kicking yourself out.

Secondly, you need to allow your body to adapt to burning fat as its primary fuel source before attempting a carb refeed. This usually takes at least 4-6 weeks. If you start carb refeeding earlier, you risk experiencing the keto flu again, and your body will need to restart the fat adaptation process, which can be an unpleasant experience.

Thirdly, carb refeeding may awaken your carb cravings, so you need to be careful if you are prone to having strong cravings. It is important to control your cravings and stick to your keto plan after a carb refeed.

Finally, carb refeeding is not recommended for individuals on a very low-carbohydrate or ketogenic diet for health reasons, such as supportive cancer treatment. Although a long-term ketogenic diet may show a few side effects, the focus in these cases is on supporting recovery.

It is not recommended for individuals on a low-carb diet for health reasons

Carb refeeding, or carb loading, is a period of time, usually a day, where a person on a keto diet intentionally consumes more carbs than usual. This practice is not recommended for beginners and can be challenging for those who are prone to strong cravings. It is also not recommended for individuals on a low-carb diet for health reasons, such as supportive cancer treatment.

The ketogenic diet is a high-fat, very low-carb diet that restricts carbs to under 50 grams per day. When carb intake is reduced, the body must burn fat for energy instead of glucose, in a process known as ketosis. While in ketosis, the body uses ketones, byproducts of fat breakdown produced by the liver, as an alternative energy source.

The cyclical ketogenic diet involves adhering to a standard ketogenic diet protocol 5-6 days per week, followed by 1-2 days of higher carb consumption. These higher-carb days are referred to as "refeeding days," as they replenish the body's depleted glucose reserves. During refeeding days, individuals should consume more carbs to break ketosis, with carbs comprising 60-70% of total calories.

However, individuals on a low-carb or ketogenic diet for health reasons should not participate in refeeding. While a long-term ketogenic diet may have some side effects, the focus is on supporting recovery. For example, a severely low-carbohydrate or ketogenic diet can be a stressor for the body, and refeeding can help to manage this stress by providing a biochemical reaction without side effects.

Additionally, a prolonged low-carbohydrate diet can lower blood leptin levels, which signals to the body that its reserves are running low, and it should conserve energy. Refeeding with carbohydrates can positively impact the hormone leptin, which is released in response to carbohydrate consumption.
