What is a 48 Hour Fast Autophagy, and How Does it Work?
Autophagy is when the body breaks down and recycles damaged or dysfunctional cellular components. It is a natural process that occurs in the body, and research has shown that it can have significant health benefits.
A 48-hour fast is a form of intermittent fasting in which a person goes without food for 48 hours. During this time, the body begins to use up its stored energy, and once those stores are depleted, it starts to break down cellular components to produce energy. This process is known as autophagy.
When the body enters a fasted state, it starts to produce ketones, molecules it can use for energy. As the body uses up its stored energy, it starts to break down damaged or dysfunctional cellular components, such as misfolded proteins, damaged mitochondria, and other debris. The body then recycles these cellular components for energy.
Research has shown that autophagy can have some health benefits. For example, it may reduce inflammation, improve insulin sensitivity, and promote cellular regeneration. It may also protect against diseases such as cancer, Alzheimer’s, and Parkinson’s.
It’s important to note that a 48-hour fast should only be attempted by healthy individuals and under the guidance of a healthcare professional. Fasting can be challenging, and it can also be dangerous for specific populations, such as pregnant women, individuals with a history of disordered eating, and those with certain medical conditions.
Health Benefits of Fasting for 48 Hours
Fasting for 48 hours, also known as a 2-day fast, is a form of intermittent fasting that involves abstaining from food for two consecutive days. While it may be challenging, research has suggested many health benefits associated with this type of fasting. Some of the potential benefits of fasting for 48 hours include the following:
Promoting autophagy
As mentioned earlier, fasting for 48 hours can trigger autophagy, a process in which the body breaks down and recycles damaged or dysfunctional cellular components. This can help to promote cellular regeneration and protect against certain diseases.
By taking the time to fast for 48 hours every now and then, you can give your body a much-needed break from energy-demanding digestion processes and allow it to catch up on vital housekeeping routines like autophagy.

Reducing inflammation
Recent studies have found that 48-hour fasting has the potential to reduce inflammation, a risk factor for many chronic diseases. This fasting can be done once per week and is widely known to lower blood pressure and glucose levels, two elements associated with inflammation.
Eating only one meal during 48 hours naturally reduces caloric intake. In addition, it stimulates the burning of fat cells in the body, thus helping decrease inflammation in common problem areas such as the joints.
Not only does this fast help decrease inflammation, but it may also improve overall wellness by enhancing your metabolism, cognitive function, and sleep quality.
Improving insulin sensitivity
Numerous studies have demonstrated the benefits of fasting as a preventative measure for metabolic disorders.
Short-term fasting has been found to increase insulin sensitivity, while 48-hour fast blood pressure can even decrease. By reducing their caloric intake and abstaining from food for 12 to 48 hours, people can significantly lower the risk of type 2 diabetes and other metabolic issues. Through short-term fasting, overall health can be improved and contribute to lasting health benefits.
Enhancing cognitive function
Some studies have suggested that fasting can enhance cognitive function, improve mental clarity, and boost brain-derived neurotrophic factors (BDNF). This protein promotes the growth and survival of brain cells.
However, it’s important to note that the research in this area is still relatively new, and more studies are needed to fully understand the potential benefits of fasting on cognitive function and brain health.
Additionally, fasting may not be appropriate for everyone, and it’s important to talk to a healthcare professional before starting a fasting regimen, especially if you have any underlying medical conditions.
Supporting weight loss
Fasting for 48 hours can help to reduce calorie intake, which over time, may contribute to weight loss. When you fast, your body switches from using glucose (sugar) for energy to using stored fat for energy. This can help to promote weight loss by reducing calorie intake and increasing fat burning.
48 Hour Fast Benefits for Improved Mental Clarity
Fasting is an all-natural method of reducing the toxins, free radicals, and inflammation that can accumulate in our bodies. By abstaining from food and drink for a period of time, we can reduce these agents that impede mental clarity.
- Enhanced cognitive function:
Fasting may help to improve cognitive function, such as memory and focus. When the body enters a fasted state, it produces ketones, which the brain uses for energy. Research has shown that this can help to boost brain-derived neurotrophic factor (BDNF), a protein that promotes the growth and survival of brain cells.
- Increased mental alertness:
Fasting increases mental alertness and clarity. Some people report feeling more focused and productive during a fasted state.
- Improved mood:
Some studies suggest that fasting may help to improve mood and reduce symptoms of anxiety and depression. This could be due to the increased production of BDNF and other mood-boosting neurotransmitters.
- Reduced brain fog:
Fasting may help to reduce brain fog, a condition characterized by confusion, forgetfulness, and difficulty concentrating. This could be because the brain is better able to utilize ketones for energy during a fast.
A 48-hour fast is particularly effective for purging these elements from our systems, providing ample time for the body’s natural detox mechanism to kick in and stimulate clear thinking.
By fuelling ourselves with healthy foods and regular fasting, we can stay mentally sharp over the long term and enjoy clearer thought patterns in times of need.
24 vs 48 Hour Fast
A 24-hour fast involves abstaining from food and caloric beverages for a full day, while a 48-hour fast consists in doing so for two consecutive days.
- There are potential benefits to both types of fasts. For example, a 24-hour fast can help improve insulin sensitivity, reduce inflammation, and promote autophagy (the process by which the body cleans up damaged cells). It can also be a valuable tool for weight loss.
- A 48-hour fast may offer additional benefits such as deeper autophagy, improved immune function, and increased growth hormone production. However, a longer fast can also be more challenging, and it is essential to consult with a healthcare professional before attempting a fast of this duration.
In general, both types of fasts can be practical tools for improving health and promoting weight loss. Still, they should be cautiously approached, especially for people with underlying medical conditions or who are pregnant or breastfeeding. Breaking a fast with healthy, nutrient-dense foods is also essential to avoid overeating and potential digestive upset.
48 vs 72 Hour Fast
A 48-hour fast involves abstaining from food and caloric beverages for two consecutive days, while a 72-hour fast consists in doing so for three successive days.
Both fasts can promote health and weight loss, but a longer fast, like a 72-hour fast, can offer additional benefits.
During a 72-hour fast, the body enters a deeper state of ketosis, where it begins to burn stored fat for energy instead of glucose from food. This can lead to increased fat burning, improved insulin sensitivity, and potential benefits for type 2 diabetes and metabolic syndrome. Additionally, a 72-hour fast may provide a fantastic opportunity for autophagy, where the body clears out damaged cells and promotes cellular regeneration.
However, a 72-hour fast can be challenging and should be cautiously approached. It is important to consult with a healthcare professional before attempting a fast of this duration, especially for people with underlying medical conditions, pregnant or breastfeeding women, and those who are underweight or have a history of disordered eating.
Regardless of the duration of the fast, it is essential to break the fast with healthy, nutrient-dense foods to avoid digestive upset and overeating.

Hello, Sarah 🙂
You’re very welcome! Fasting can indeed offer various health benefits, but it’s important to consult with a healthcare professional before starting any fasting regimen to ensure it’s safe and suitable for your individual needs and circumstances.
I tried OMAD- also 20 hour fast – my only concern with 48 and all these fasts is stomach upset- like foods go thru me quickly. Any advice for first consumption- and can a 48 hour fast include black coffee or teas
Thank you – very good information
Hello, Julie! 👋
For the first consumption after a 48-hour fast, opt for easily digestible foods like fruits or vegetables to avoid stomach upset. Stay hydrated with water, herbal teas, or bone broth, and you can include black coffee or teas in moderation during the fast. Monitor your body’s response and consider consulting a healthcare professional, especially if you have concerns about digestion or any underlying health conditions. Good luck!
I am very healthy. Will Eating once every 48 hours continuously for at least a year be a harmful practice ?
Hi, AYO!
Eating once every 48 hours continuously for at least a year may pose risks such as nutrient deficiencies and low energy levels. Consult a healthcare professional before attempting such fasting to ensure it aligns with your health needs.🙌
Thank you so much for this information! Quick question – in the final thoughts paragraph it mentions to do a 48 hour fast twice a week, equaling to 4 days of fasting out of a 7 day week. Does it really mean twice a week, or did it perhaps mean twice per month or…?
Hey Judi💫
The recommendation in the final thoughts paragraph is indeed to do a 48-hour fast twice a week, totaling four days of fasting within a seven-day week. It emphasizes the benefits of this specific fasting pattern, but it’s essential to note that fasting frequencies can vary based on individual preferences, health conditions, and goals. If you have concerns or specific health considerations, it’s advisable to consult with a healthcare professional for personalized guidance.🌷
Hello, For 8 months, every week I did 48 hour fasting twice a week and on the rest of the 5 days, did OMAD( one meal a day), totaling 6 to 7 meals a week. Results were phenomenal:
1) I lost 20lbs
2) Elevated fasting glucose(118), A1C(5.8%), non HCL cholesterol(141) and LDL-Calculated (118) all came to back normal range: fasting glucose(99), A1C(5.5%), non HCL cholesterol(103) and LDL-Calculated (83)
3)Lost some head hair
4) Mild eczema on 2 fingers on left hand totally gone.
5) I’m off BP and statin for now with repeat labs in 3 months since all numbers are in range.
Question: Since I have reached my weight goal, I’m planning to cut back to 48 hour fast once a week with OMAD on rest 6 days of the week. Is this healthier option to continue for long term?
Hello, Ash 👋
Thank you for sharing your success!
Transitioning to a 48-hour fast once a week with OMAD on the other days can be a sustainable option for the long term, especially since you’ve reached your weight goal. However, it’s crucial to monitor your body’s response, energy levels, and consult with a healthcare professional for personalized advice and regular check-ups. Individual responses to fasting vary, so paying attention to your body’s signals is important ☝️ 🙌
