Keto Carb Refeed: Timing And Strategies For Success

The cyclical ketogenic diet is a variation of the standard ketogenic diet, which involves adhering to a strict high-fat, low-carb ketogenic meal plan for 5-6 days per week, followed by 1-2 days of higher carb consumption. This period of increased carbohydrate intake is known as a refeed or refeed day, and it is intended to replenish the body's depleted glucose reserves. The recommended amount of carbs during a refeed is between 50-300g, depending on the individual's activity levels, genetics, and other factors. While the cyclical ketogenic diet is popular among those seeking muscle growth and improved exercise performance, there is limited research on its effectiveness and potential side effects. It is important to note that a refeed day is different from a cheat day, as it involves thoughtful planning and controlled food intake, with a focus on carbs.

A carb refeed is an intentional increase in carb consumption

A carb refeed is an intentional increase in carbohydrate consumption, often done on a periodic basis such as daily or weekly. Carb refeeds are an effective strategy for minimising the potential negative hormonal or metabolic effects of long-term low-carbohydrate intake. Carbohydrates have an impact on the hormone insulin, which is responsible for telling our cells to soak up sugar from the bloodstream. If your body doesn't respond properly to insulin, you increase your risk for diseases like metabolic syndrome, type II diabetes, heart disease, and Alzheimer's.

Low-carb diets have been shown to be beneficial for weight management, type II diabetes, and neurological disorders, likely due to the restriction of carbohydrates and the ensuing positive effect on lowering blood sugar levels. However, one of the drawbacks of a long-term, very low-carb diet is that insulin levels can become chronically low, which can actually cause cells to become resistant to insulin signalling. Chronically high and low insulin levels can have similar negative effects on health, so the goal is to strike a balance of optimal insulin sensitivity.

Carb refeeds can be particularly beneficial for individuals experiencing weight loss plateaus, hormone imbalances, low energy, or a decline in athletic performance as a result of their low-carb diet. The refeed can give a hormonal boost, improve physical performance, and lower the risk of binging.

There are different ways to incorporate a carb refeed into your diet, depending on your goals and activity levels. For example, individuals who engage in lower amounts of physical activity can pick one day or one meal per week to eat a larger amount of carbohydrates. For those who perform intense training sessions, it is recommended to increase your normal amount of carbohydrates in your first meal post-workout. Serious athletes might pick a meal to consume a larger amount of carbs, usually post-workout at dinner.

It's important to note that the cyclical ketogenic diet, which involves rotating between a strict high-fat, low-carb ketogenic meal plan and higher carb intake days, is not the same as carb cycling. Carb cycling involves cutting carbs on certain days and increasing intake on others, without reducing overall carb intake drastically enough to reach ketosis.

Carb refeeds are done periodically, such as daily or weekly

Carb refeeds are an intentional increase in carbohydrate consumption and are done periodically, such as daily or weekly. They are an effective strategy for minimising the potential negative hormonal or metabolic effects of long-term low carbohydrate intake. Carb refeeds are also known as "refeeding days" as they replenish the body's depleted glucose reserves.

There are different ways to incorporate carb refeeds into your diet, depending on your goals, needs, and body. Here are some common methods:

• For individuals seeking the health benefits of a low-carbohydrate diet while avoiding negative long-term effects, it is recommended to pick one day or one meal per week to eat a larger amount of carbohydrates. This could be on a weekend or your most physically active day. The recommended amount of carbohydrates for this method is 100-300g, depending on the individual.
• For individuals who perform intense training sessions a few times a week and want to optimise performance and recovery while maintaining ideal body composition, it is suggested to increase your normal amount of carbohydrates in your first meal post-workout on big training days. The recommended amount of carbohydrates for this method is 50-150g, depending on the individual.
• For serious athletes who train nearly every day or multiple times a day and need enhanced recovery between sessions, pick a meal to consume a larger amount of carbs, usually post-workout or at dinner. The recommended amount of carbohydrates for this method is 50-200g, depending on the individual.

It is important to note that the recommended amount of carbohydrates per day varies depending on individual factors such as activity levels, genetics, and biomarkers. Additionally, the type of carbohydrates consumed matters. It is generally recommended to choose unrefined, complex carbohydrates from whole-food sources, such as starchy vegetables, properly prepared grains, and nutritive sweeteners.

Carb refeeds are typically paired with the keto diet, which is a high-fat, very low-carb diet. When following a ketogenic diet, you normally restrict carbs to under 50 grams per day. During the refeeding days, you increase your carb consumption to break ketosis. This involves consuming 60-70% of your total calories from carbohydrates, with protein accounting for 15-20% and fats delivering just 5-10%.

The cyclical ketogenic diet involves adhering to a standard ketogenic diet protocol for 5-6 days per week, followed by 1-2 days of higher carb consumption. This approach may provide several benefits, such as boosting athletic performance, increasing fibre intake, promoting muscle growth, and making the keto diet more sustainable. However, it is important to note that research on the cyclical ketogenic diet is limited, and its long-term benefits and side effects are not yet fully understood.

Carb refeeds can help to minimise the negative effects of long-term low carb intake

Carb Refeeds: Minimising the Negative Effects of Long-Term Low-Carb Intake

Carb refeeding is an effective strategy for minimising the potential negative metabolic and hormonal effects of long-term low-carbohydrate intake. Carb refeeds can help to maintain optimal insulin sensitivity and balance leptin levels, reducing the risk of disease and improving overall health.

Insulin Sensitivity

Insulin is a hormone that regulates blood sugar levels by telling cells to absorb sugar from the bloodstream. When the body does not respond properly to insulin, cells become resistant to insulin signalling, leading to elevated blood sugar levels that can have toxic effects. This condition is known as "insulin resistance".

Chronically high and low insulin levels can have similar negative impacts on health. Therefore, the goal is to achieve optimal insulin sensitivity by balancing insulin levels. Carb refeeds can help to achieve this balance by providing a periodic increase in carbohydrate consumption, which stimulates insulin secretion and prevents chronically low insulin levels.

Leptin Levels

Leptin is a hormone released by fat cells that communicates the body's energy reserves to the brain. When leptin levels are low, the brain responds by increasing food cravings, particularly for calorie-dense foods, and reducing energy levels. A decrease in leptin levels can also lead to weight loss plateaus.

Increasing carb intake has been shown to boost leptin levels and alleviate these negative symptoms. Carb refeeds can help to regulate leptin levels, improving weight loss efforts and overall energy levels.

Physical Performance

Carbohydrates are essential for optimal physical performance, especially during high-intensity exercises. They provide fuel for the muscles in the form of glycogen. Long-term low-carb dieting can lead to depleted glycogen levels in the muscles and liver, hindering athletic performance.

Carb refeeds can help to replenish glycogen stores, enhancing physical performance and improving recovery. This is especially beneficial for serious athletes who train regularly and need to optimise their recovery between sessions.

How to Implement Carb Refeeds

The frequency and amount of carbs consumed during a carb refeed will depend on individual factors such as activity levels, genetics, and biomarkers. For those who engage in lower physical activity, a weekly carb refeed of 100-300g of carbohydrates may be recommended. For serious athletes, a post-workout carb refeed of 50-200g of carbohydrates can enhance recovery and performance.

It is important to note that carb refeeds should be done in a controlled manner and should not be an excuse to cheat on a keto diet. Whole foods with a lower glycemic index, such as starchy vegetables, properly prepared grains, and nutritive sweeteners, are recommended during carb refeeds.

Refeeding with carbs may be beneficial for elite athletes

Carbohydrates are the body's main source of energy for athletic events. Consuming carbs before exercise can help restore glycogen stores, which may be called upon during prolonged training and in high-intensity competition. Carbohydrate meals should be low in fat, easily digested, and tolerated by the athlete. Fat intake should be limited as it delays stomach emptying time and takes longer to digest.

Carbohydrates are needed for optimal high-intensity performance as they provide fuel for the muscles in the form of glycogen. Long-term low-carb dieting can lead to depleted glycogen in muscles and hinder the ability to perform high-intensity exercise. Carbohydrates are particularly important for elite athletes who need to enhance recovery between training sessions.

There are different ways to do carb refeeds, depending on the individual's activity levels, genetics, and biomarkers. One common method is to pick one day or one meal per week to eat a larger amount of carbohydrates. For example, an elite athlete might consume 50-200g of carbs in a refeed meal, depending on their level of activity.

Carb refeeds can be beneficial for elite athletes by providing an energy boost, improving performance, and enhancing recovery. However, it is important to note that carb refeeds should be done in a controlled manner and should not turn into a carb-loading week or month. Additionally, it is recommended that individuals first adapt to burning fat as their primary fuel source before incorporating carb refeeds into their diet.

Carb refeeds can help to replenish glycogen stores

Carb refeeds are an intentional increase in carbohydrate consumption for a short period, usually a day, but it could be as short as one meal or as long as two days. Carb refeeds are important as they can help to replenish glycogen stores, which are crucial for high-intensity activities. Glycogen is a type of energy stored in the muscles and liver and is made when the body breaks down carbohydrates into glucose.

When following a ketogenic diet, the body primarily relies on fat for fuel, but glycogen remains an important energy source. Glycogen depletion can occur over time on a strict ketogenic diet, potentially leading to decreased performance and energy levels. This is where carb refeeds come into play. By temporarily increasing carbohydrate intake, individuals can replenish glycogen stores, providing a quick source of energy for activities requiring immediate bursts of power. This is particularly beneficial for athletes and individuals with high physical demands, as it improves performance, enhances muscle recovery, and boosts muscle glycogen storage.

The timing of a carb refeed is crucial. It is generally recommended to schedule refeed days on or around high-intensity workout days to ensure the increased carbohydrate intake is efficiently utilised for energy and muscle recovery. It is also important to note that carb refeeds are not intended to disrupt the state of ketosis permanently but to offer a strategic break. Carb refeeds are meticulously planned to ensure the increase in carbohydrates is controlled and beneficial, addressing specific physiological needs.

To effectively replenish glycogen stores, it is essential to choose the right types of carbohydrates. Focus on high-quality, nutrient-dense carbohydrate sources such as whole grains, fruits, starchy vegetables, legumes, and dairy products. These foods provide a steady and controlled release of glucose, supporting energy levels, performance, and overall well-being.
