From debunking the claim that it slows down your metabolism to explaining why it won’t make you lose muscle mass, we’ll separate fact from fiction and give you the truth about this popular fasting method. So, grab a cup of tea and let’s get to it!
Myth 1: Extended fasting leads to muscle loss
Misconception about muscle breakdown
One of the most common myths surrounding extended fasting is the belief that it leads to muscle loss. Many people worry that when they fast for an extended period, their body will break down muscle tissue for energy, resulting in a loss of muscle mass. However, this belief is not supported by scientific evidence.
The role of growth hormone in muscle preservation
During fasting, the body undergoes a series of biochemical processes to ensure survival. One important hormone involved in this process is growth hormone (GH). GH levels increase during fasting, promoting muscle preservation. It stimulates protein synthesis and prevents muscle breakdown, helping to maintain muscle mass even in the absence of food.
Studies showing muscle preservation during fasting
Numerous studies have been conducted to investigate the effect of extended fasting on muscle mass. One study published in the Journal of Translational Medicine found that participants who fasted for 24-72 hours experienced no significant muscle loss. Another study published in the American Journal of Clinical Nutrition showed that intermittent fasting, which involves regular periods of fasting, actually led to an increase in lean muscle mass.
These studies debunk the myth that extended fasting causes muscle loss, highlighting the body’s adaptive mechanisms to preserve muscle mass during periods of food restriction.
Myth 2: Extended fasting lowers metabolism
Understanding the body’s adaptive response to fasting
Another misconception about extended fasting is that it lowers metabolism. People often believe that when they go without food for an extended period, their metabolism will slow down, making it difficult to maintain weight loss. However, this belief does not align with the body’s natural response to fasting.
Effects on metabolic rate
During fasting, the body enters a state of ketosis, where it starts to rely on stored fat for fuel instead of glucose from food. This metabolic shift actually increases the metabolic rate, as the body requires energy to convert fat into ketones, which serve as an alternative fuel source. Research has shown that fasting can increase resting metabolic rate by up to 14%.
Research on metabolic changes during fasting
Several studies have investigated the metabolic changes that occur during extended fasting. One study published in the journal Cell Metabolism found that fasting for 72 hours led to an increase in fat oxidation and a decrease in glucose utilization, indicating a shift in metabolism toward fat burning. Another study published in the Journal of Clinical Investigation showed that fasting can increase insulin sensitivity, leading to improved metabolic health.
These studies debunk the myth that extended fasting lowers metabolism, highlighting the body’s ability to adapt and optimize metabolic processes during periods of fasting.
Myth 3: Extended fasting is dangerous
Importance of medical supervision
Extended fasting should always be approached with caution and under the guidance of a healthcare professional, especially for individuals with underlying health conditions.

One misconception about extended fasting is that it leads to nutrient deficiencies. While it is true that fasting involves a temporary reduction in nutrient intake, the body has remarkable mechanisms to conserve nutrients and ensure optimal functioning.
Role of autophagy in nutrient recycling
During fasting, the body activates a process called autophagy, which involves the breakdown and recycling of damaged cells and cellular components. This process helps to conserve nutrients by repurposing and reusing cellular materials. Autophagy promotes cellular health and plays a crucial role in nutrient recycling during periods of fasting.
Research on nutrient levels during fasting
Studies have shown that fasting does not necessarily lead to nutrient deficiencies. One study published in the journal PLoS ONE found that individuals who underwent an extended water-only fast for up to 21 days did not experience significant changes in nutrient levels. This suggests that the body can effectively regulate nutrient balance during fasting, minimizing the risk of deficiencies.
These findings challenge the myth that extended fasting causes nutrient deficiencies, highlighting the body’s ability to conserve and recycle nutrients during periods of food restriction.
Myth 5: Extended fasting leads to binge eating
Addressing psychological factors
One concern that people often have about extended fasting is that it may lead to binge eating or an unhealthy relationship with food. While it is important to approach fasting with a healthy mindset, it is not inherently a cause of binge eating.
Importance of mindful eating
To prevent binge eating after fasting, it is crucial to cultivate a mindset of mindful eating. This involves being present and attentive during meals, listening to your body’s hunger and fullness cues, and making conscious food choices. By adopting a mindful eating approach, you can develop a healthier relationship with food and reduce the risk of binge eating episodes.

By making sustainable dietary choices, you can maintain a healthy eating pattern and minimize the risk of binge eating or weight regain.
By practicing mindful eating and adopting a sustainable approach to post-fasting meals, you can mitigate the risk of binge eating and maintain a healthy relationship with food.
Myth 6: Extended fasting only benefits weight loss
Understanding the broader health benefits
While weight loss is one of the most well-known benefits of extended fasting, it is not the only advantage. Extended fasting has been shown to have a range of positive effects on overall health and well-being.
Impact on insulin sensitivity
Extended fasting has been found to improve insulin sensitivity, which is crucial for maintaining stable blood sugar levels and preventing the development of conditions like type 2 diabetes. By reducing insulin resistance, fasting can enhance the body’s ability to effectively utilize and regulate glucose.
Research on disease prevention and longevity
Numerous studies have indicated that extended fasting may have potential benefits for disease prevention and longevity. Research published in the journal Cell Stem Cell suggested that prolonged fasting can activate stem cells and promote regeneration and rejuvenation in various tissues. Other studies have shown that fasting may help reduce the risk of chronic diseases such as cardiovascular disease and certain types of cancer.
By recognizing the broader health benefits of extended fasting beyond weight loss, individuals can appreciate the potential positive impact on their overall well-being.
Myth 7: Extended fasting disrupts sleep patterns
Effects of fasting on sleep quality
Some people worry that extended fasting may disrupt their sleep patterns. However, research suggests that this is not necessarily the case. In fact, fasting can have positive effects on sleep quality for many individuals.
