Refeed Meals On Keto: Are They Necessary?

The ketogenic diet is a popular, low-carb, high-fat eating regime. While it is often considered inflexible, there are variations, such as the cyclical ketogenic diet, which involves adhering to a standard keto diet for 5-6 days a week, followed by 1-2 days of higher-carb intake, known as refeeding days.

Refeeding days are meant to replenish your body's depleted glucose reserves, and are believed to be beneficial for muscle growth and improved exercise performance. However, there is limited research on the effectiveness of the cyclical keto diet, and it is not known whether it is more effective than the standard keto diet in terms of boosting muscle mass or improving athletic performance.

Therefore, it is unclear whether refeed meals are necessary for those on the keto diet. While some sources suggest that refeed days can help take weight loss to the next level, others argue that sticking to the fundamentals of a solid keto diet is sufficient for achieving health, weight loss, and happiness.

Refeed days can help prevent a weight loss plateau

Refeed days can be an effective strategy to prevent a weight loss plateau. A refeed day is a planned increase in calories for a day, typically done on a weekly or bi-weekly basis. It is intended to give your body a break from calorie restriction.

When you are in a calorie deficit, your leptin levels decrease. Leptin is a hormone produced by fat cells that signals to your body that it has adequate fat stores, helping to regulate appetite and calorie burning. Low levels of leptin signal to your brain that you are entering a period of calorie deprivation, and your body will respond by increasing your appetite and reducing the number of calories burned. This is known as adaptive thermogenesis, a survival process that slows weight loss.

By introducing a refeed day, you can temporarily increase your leptin levels through increased calorie intake, which may help to keep your body's fat-burning process working more efficiently. Carbohydrates are particularly effective at increasing leptin levels compared to fats or proteins. Therefore, by consuming carb-rich foods on a refeed day, you are more likely to balance your leptin levels and prevent a weight loss plateau.

In addition to preventing a weight loss plateau, refeed days may also provide other benefits such as lowering the risk of binging and improving physical performance. However, it is important to note that there is limited research on the topic, and refeed days may not be suitable for everyone, especially those with a history of disordered eating.

Refeeding may lower the risk of binging

Refeeding is a planned increase in calories for a day on a weekly or bi-weekly basis. It is intended to give your body a break from calorie restriction. While it may sound similar to a cheat day, the two are very different. Cheat days involve uncontrolled and unplanned eating, with no restrictions on the type and amount of food consumed. On the other hand, refeeding involves thoughtful planning and controlled food intake, with a focus on increasing calories from carbohydrates rather than fats and proteins.

Benefits of Refeeding

Refeeding can be beneficial in lowering the risk of binging. Food restriction often leads to overeating or binging, and while cheat days are designed to allow this, they may lead to a distorted relationship with food. In contrast, refeeding gently and purposefully increases calories, which may reduce the urge to binge. It allows for the inclusion of foods typically restricted by diet plans, especially those rich in carbohydrates, helping to satisfy cravings and reduce feelings of deprivation.

How Refeeding Works

The human body adapts to eating patterns over time. When calories are restricted, leptin levels decrease, and the body receives signals to eat more food and burn fewer calories. This process is known as adaptive thermogenesis. Refeeding days can help increase leptin levels, reducing the effects of adaptive thermogenesis and preventing a weight loss plateau.

Who Should Refeed?

Refeeding can be beneficial for those who have reached a weight loss plateau, especially if they are already close to their target weight. It can also be useful for those who have been following a low-carb diet and experiencing negative side effects such as hormone imbalances, low energy, or a decline in athletic performance.

How to Refeed

The basic concept of refeeding is to increase carbohydrate consumption on specific days or meals. The recommended amount of carbohydrates during a refeed depends on the individual and their activity levels, but it typically ranges from 100-300 grams. It is important to limit fat intake during refeeding days to avoid a massive calorie blowout.

Refeeding can be a valuable tool to enhance weight loss efforts and improve overall well-being. It provides a psychological boost and helps satisfy cravings, reducing the urge to binge. However, it should be noted that refeeding may not be suitable for everyone, especially those with a history of disordered eating. It is always recommended to consult a healthcare professional before making any significant changes to your diet.

Refeeding may improve physical performance

Refeeding is a strategic increase in carbohydrate consumption, often done periodically, such as daily or weekly. It is an effective strategy to minimise the negative hormonal or metabolic effects of long-term low-carbohydrate intake.

Carbohydrates and Physical Performance

Carbohydrates are essential for optimal high-intensity performance as they provide fuel for the muscles in the form of glycogen. Long-term low-carb dieting can deplete glycogen in muscles and the liver, hindering the ability to perform high-intensity exercise.

Benefits of Refeeding for Athletes

Refeeding with carbohydrates may benefit athletes who follow very low-carb diets. A study involving 29 elite race walkers found that those who received periodic high-carb feedings before training sessions experienced significant performance improvements compared to those on a standard keto diet.

Busting Weight Loss Plateaus

Refeeding can help take weight loss to the next level, especially when an individual is close to their target weight. A sudden increase in carbohydrates results in a boost in leptin, a hormone that regulates appetite and energy expenditure. This helps to break the cycle of weight loss plateaus and cravings for unhealthy foods.

Experimenting with Refeeding Strategies

There are various methods for implementing refeeding strategies, and experimentation is necessary to determine the best approach for an individual. Some people may benefit from scheduling refeeds for days with heavy physical activity, allowing their bodies to absorb the shock to the system and enhance fat loss. Others may prefer mini refeeds after intense training sessions to refuel their bodies and boost leptin levels.

Overall Benefits of Refeeding

Refeeding can provide both physical and psychological benefits. It can lead to increased energy levels, promote weight loss, and reduce cravings for unhealthy foods. Additionally, refeeding can improve athletic performance and aid in breaking through weight loss plateaus.

Refeeding can help regulate hormones

Refeeding days, which involve a planned increase in calories and carbohydrates, can help to counteract this. Carbohydrates have a direct impact on insulin, and when the body doesn't respond properly to insulin, the risk for diseases like metabolic syndrome, type II diabetes, heart disease, and Alzheimer's increases. Insulin is also a signalling hormone for the thyroid, bones, brain, and other hormones. Therefore, it is vital to keep cells responsive or sensitive to insulin, which can be achieved by eating the right amount and type of carbohydrates at the right time.

Leptin levels have been shown to increase with a boost in carb intake. This can help alleviate the negative symptoms associated with low leptin levels, such as food cravings, mood swings, low energy, and plateaued fat loss efforts. By incorporating refeed days, you may be able to regulate your hormones, specifically leptin, and prevent weight loss plateaus.

Refeeding can help replenish glycogen stores

Refeeding is a strategic increase in carbohydrate consumption, often done daily or weekly, to minimise the negative hormonal or metabolic effects of long-term low-carbohydrate intake. It is particularly beneficial for individuals on a ketogenic diet, which is a very low-carb, high-fat diet.

By incorporating refeed days, individuals can enhance their athletic performance and improve their recovery. For example, athletes can schedule their refeed days to align with their heavy training days. By doing so, they can deplete their glycogen levels during training and then refill them with a carb-heavy meal afterward. This strategy optimises the body's utilisation of carbohydrates for energy and supports muscle recovery.

Additionally, refeeding can help break the cycle of weight loss plateaus. When individuals restrict their calories and consume fewer carbohydrates, their leptin levels decrease. Leptin is a hormone that regulates appetite and energy expenditure. Low leptin levels result in increased hunger signals and cravings for calorically dense, unhealthy foods. By periodically increasing carbohydrate intake through refeeding, individuals can boost their leptin levels, which helps suppress appetite and enhance weight loss.

In summary, refeeding is a valuable tool for individuals on a ketogenic or low-carb diet. By incorporating strategic refeed days, individuals can replenish their glycogen stores, optimise athletic performance, enhance recovery, and overcome weight loss plateaus by regulating their leptin levels.
