Intermittent fasting, including a weekly 36-hour fast, has gained popularity due to its numerous health benefits. Fasting has been practised for centuries for various reasons, including religious, cultural, and health purposes. While fasting may not be suitable for everyone, it is said to promote weight loss, improve metabolic health, enhance brain function, and increase longevity. It also reduces inflammation, improves insulin sensitivity, and promotes hormonal balance. However, extended periods of fasting may cause more harm than good, and it is always recommended to consult a healthcare professional before starting any fasting regimen.

What You'll Learn
Intermittent fasting improves metabolic health
Intermittent fasting is an eating pattern that involves periods of food restriction, called fasting, followed by a period of regular eating. This pattern of eating could help you lose weight, reduce your risk of disease, and increase your lifespan. Intermittent fasting has been linked to improved metabolic health and multiple health benefits.
Alternate-day fasting (ADF) is an extreme dietary intervention that involves not eating for 36 hours and then eating as much as you want in the following 12 hours. While this may not be the best method for long-term health, less extreme versions of intermittent fasting can help. A 2014 review found that intermittent fasting could help people lose 3–8% of their body weight in 3–24 weeks.
Intermittent fasting has been shown to improve metabolic health by influencing metabolic regulation via effects on circadian biology, the gut microbiome, and modifiable lifestyle behaviors, such as sleep. Fasting triggers autophagy, allowing the body to efficiently remove dysfunctional components and enhance overall cellular function. It also improves insulin sensitivity, allowing your body to regulate blood sugar levels more efficiently. This reduction in insulin resistance can help protect against Type 2 Diabetes.
Intermittent fasting also boosts several fat-burning hormones, including norepinephrine, which promotes fat burning. Human growth hormone (HGH) levels also increase during extended fasts, improving muscle growth, metabolism, and recovery. Fasting also gives your digestive system a break, allowing your body to focus on detoxification processes. Regular fasting can improve various cardiovascular markers, including blood pressure, cholesterol levels, and triglycerides, which reduces heart disease risk.

Fasting boosts weight loss
Intermittent fasting has gained popularity due to its numerous health benefits, including weight loss. Intermittent fasting involves switching between fasting and eating on a regular schedule. This type of fasting can help manage weight or even prevent or reverse some forms of disease.
Alternate-day fasting (ADF) is a type of intermittent fasting that involves not eating for 36 hours and then eating as much as one wants during a 12-hour window. While this is considered an extreme form of dietary intervention, it has been found to be beneficial for weight loss. A study found that participants who fasted for 36 hours showed reduced weight, body fat, and improved markers for cardiovascular disease risk, such as lower cholesterol levels.
Another benefit of intermittent fasting is its ability to promote autophagy, which is crucial for maintaining cellular health and preventing the accumulation of cellular debris that can lead to diseases. Fasting triggers autophagy, allowing the body to remove damaged cells and enhance overall cellular function.
Additionally, fasting improves insulin sensitivity, which helps regulate blood sugar levels and reduces the risk of type 2 diabetes. It also boosts the secretion of human growth hormone, which is important for muscle growth, fat metabolism, and overall body composition.
While intermittent fasting can be a powerful tool for weight loss and overall health, it may not be suitable or safe for everyone. It is always recommended to consult with a healthcare provider before starting any fasting regimen, especially if there are underlying health conditions.

Fasting improves hormonal balance
Intermittent fasting, including a weekly 36-hour fast, has gained popularity due to its numerous health benefits. One of the most significant advantages of this type of fasting is its positive impact on hormonal balance.
Hormonal balance is essential for overall health, and fasting can help regulate the production of key hormones. For example, fasting boosts the secretion of human growth hormone (HGH), which plays a crucial role in muscle growth, fat metabolism, and overall body composition. It also improves insulin sensitivity, allowing the body to regulate blood sugar levels more effectively. This reduction in insulin resistance can help protect against Type 2 Diabetes and improve overall metabolic health.
Fasting can also help regulate cortisol levels, the primary stress hormone. While short-term fasting may lead to an initial increase in cortisol as a natural response to stress and low blood sugar, extended periods of fasting can cause cortisol levels to drop. This reduction in cortisol can potentially decrease the risk of developing stress-related health issues.
For women, fasting can help balance reproductive hormones, supporting menstrual health and fertility. Studies suggest that intermittent fasting may decrease androgen markers in premenopausal females, especially those with polycystic ovarian syndrome (PCOS). This can lead to improved menstruation and fertility, as well as a reduction in hyperandrogenic symptoms such as hirsutism, acne, and androgenic alopecia.
Additionally, fasting can improve appetite control by regulating the hormones leptin and ghrelin. Leptin levels tend to decrease during fasting, signalling to the brain that the body's energy reserves are depleting and increasing appetite. Over time, leptin levels stabilise, improving the body's ability to control hunger. Ghrelin, also known as the "hunger hormone," typically increases during fasting, stimulating appetite. However, as the body adjusts to fasting periods, these hormones stabilise, leading to better control over cravings and dietary habits.

Fasting improves gut health
Fasting for 36 hours is an extreme form of intermittent fasting, which has gained popularity due to its health benefits. Intermittent fasting is an eating pattern where you only eat during certain parts of the day. This can include time-restricted feeding, where you restrict your eating to a certain number of hours each day, or weekly fasting, where you restrict what you eat on two to three non-consecutive days per week.
Taking regular breaks from eating through intermittent fasting can help alleviate stress on your digestive system and promote overall gut health. Fasting can increase gut microbiome diversity, making the bacteria in your gut more diverse. This includes the rapid expansion of Akkermansia muciniphila, a bacteria associated with positive health markers such as decreased intestinal inflammation and a healthier gut barrier.
Fasting also triggers autophagy, a process where cells clean and repair damaged components, which is crucial for maintaining cellular health and preventing the accumulation of cellular debris that can lead to diseases such as cancer and neurodegenerative disorders. Fasting also gives your digestive system a break, allowing your body to focus on detoxification processes and removing damaged cells.
In addition to improving gut health, the benefits of 36-hour fasting include improved metabolic health, reduced belly fat and body weight, enhanced brain function, and hormonal balance. However, it is important to note that fasting may not be suitable for everyone, and those with underlying health conditions should consult a healthcare provider before starting any fasting regimen.

Fasting improves brain function
Fasting for 36 hours is an extreme form of intermittent fasting, which has gained popularity due to its health benefits. Intermittent fasting has been shown to improve brain function and reduce the risk of neurodegenerative diseases.
Brain-Derived Neurotrophic Factor (BDNF)
Fasting increases the production of BDNF, a protein that supports the survival of neurons and encourages the growth of new neurons and synapses. This can lead to improved cognitive function, learning, and memory.
Reduced Inflammation
Intermittent fasting helps to decrease inflammation in the body, including the brain. Chronic inflammation is linked to neurological disorders such as Alzheimer's, Parkinson's, and multiple sclerosis. By reducing inflammation, intermittent fasting may lower the risk of these disorders.
Autophagy
During fasting, cells undergo a process called autophagy, which involves removing and recycling damaged cellular components. This process is crucial for maintaining proper cellular function and can help protect the brain from age-related degeneration and neurodegenerative diseases.
Neurogenesis
Some studies suggest that intermittent fasting may promote neurogenesis, or the growth of new neurons, in the hippocampus, a brain region associated with learning and memory. This could contribute to improved cognitive function and a reduced risk of neurodegenerative diseases.
Weight Loss
Intermittent fasting can aid in weight loss, which is associated with improved brain function. Obesity is linked to a greater risk of developing neurological diseases and cognitive impairment. By reducing weight and body fat, intermittent fasting may indirectly lead to improved cognitive functioning.
While fasting for 36 hours may provide these benefits, it is important to note that this is an extreme form of intermittent fasting and may not be suitable for everyone. It is always recommended to consult a healthcare professional before starting any fasting regimen, especially if you have underlying health conditions.
