The Anti-aging Benefits of Intermittent Fasting 

By Dr. Benjamin Busch, DO

What is Intermittent Fasting?

Intermittent fasting is a dietary practice in which people restrict their meal consumption to specific times of the day. Some studies indicate that it may provide benefits other than weight loss, such as better brain and heart health.

Intermittent fasting has recently received much interest as a potential anti-aging tool. 

Intermittent fasting involves cycling between eating and fasting periods, with numerous options. While the primary goal of intermittent fasting is frequently weight loss or improved metabolic health, there is evidence that it may also have anti-aging benefits.

From cellular repair to reduced inflammation and decreased oxidative stress, intermittent fasting has been proven to be beneficial in terms of several aspects known to slow down the body’s aging process. While there is still much to understand about intermittent fasting’s anti-aging advantages, it is evident that this eating pattern has the potential to support healthy aging. 

On the other hand, fasting may only be suitable for some and should be addressed carefully. While starting any new diet or fasting plan, consulting a healthcare expert is a sensible approach.

Let’s move ahead and have a look at some anti-aging benefits of intermittent fasting.

Can intermittent fasting reverse aging?

While studying the effects of calorie restriction in overweight adults, research studies suggest that calorie restriction improves energy production and decreases the risk of certain chronic diseases such as heart disease, diabetes, and cancer. 

By digging further, scientists discovered that caloric restriction reduces cellular damage and supports the preservation of healthy DNA. These are the two essential elements used in the battle against aging since aging begins with the breakdown of DNA. As a result, the damaged and inflamed cells lead to various chronic diseases. 

Therefore, intermittent fasting has become famous for maintaining good health and weight loss. 

What are the anti-aging benefits of intermittent fasting?

Some of the potential anti-aging effects of intermittent fasting include;

  • Cellular repair
  • Reduced inflammation 
  • Increased synthesis of human growth hormone
  • Enhanced insulin sensitivity
  • Increased mitochondrial function
  • Improved cognitive health
  • Reduced oxidative stress
  1. Feel youthful by activating the body’s cleansing system, autophagy.

Fasting boosts the process of autophagy in your body. Autophagy is a simple cellular process in which the cells remove harmful proteins or defective organelles from the cell. This process lowers the risks of age-related illnesses and improves cellular function.                                                

  1. Slow down aging with reduced inflammation.

Age-related inflammation and chronic inflammation are both linked to the aging process. It has been found that intermittent fasting lowers inflammation, which slows down the process of aging.   

  1. Reduce the risk of Diabetes with improved insulin sensitivity.

Intermittent fasting can help improve insulin sensitivity, which in turn reduces the possibility of type 2 diabetes, a condition that is commonly linked to the aging process. 

  1. Improve metabolic functions of the body with proper hormone regulation.

Intermittent fasting positively impacts the regulation of hormones within the body. Fasting increases the production of human growth hormone (HGH). HGH is essential in various bodily processes, such as muscle growth, tissue repair, and improved metabolic rates. Higher levels of HGH lead to potential anti-aging benefits. 

  1. Feel more energetic with Mitochondrial increased function.

Mitochondria, the energy powerhouse, is an energy-producing organelle within the cell. The functionality of mitochondria tends to decline as a person ages. This ultimately results in aging, followed by various age-related illnesses. Intermittent fasting has proved to be quite helpful in improving mitochondrial function, leading to better overall cellular health.

  1. Reduced risk of neurodegenerative disorders with improved cognitive function.

It has been found that intermittent fasting is quite effective in improving certain cognitive functions and reducing the risks of neurodegenerative disorders such as Parkinson’s disease and Alzheimer’s disease. This leads to better brain health as we age. 

  1. Feel healthier with reduced oxidative stress.

An imbalance between the free radicals and the body’s detoxification ability results in oxidative stress. Oxidative stress plays a significant role in aging, leading to age-related disorders. It has been found that intermittent fasting reduces oxidative stress, thus slowing down the aging process. 

Despite the anti-aging effects of intermittent fasting, most people find it difficult to sustain a diet that requires less calorie intake for an extended period of time. 

What are some common types of intermittent fasting?

Intermittent fasting is a versatile eating pattern that can be tailored to fit a variety of lifestyles and tastes. Here is an overview of the most common types of intermittent fasting. 

  1. Alternate-day fasting
  2. Weekly 24-hour fasting
  3. 5:2 diet
  4. Fasting 12 hours a day
  5. The Leangains Diet
  6. Warrior Diet
  1. Alternate-day fasting

Alternate-day fasting is intermittent fasting, in which a person fasts every other day. Although it is associated with potential anti-aging benefits like cellular repair and weight loss, it comes with challenges like difficulty in navigating social situations like family gatherings and dinners.

  1. Weekly 24-hour fasting

Weekly 24-hour fasting is intermittent fasting in which an individual fasts for 24 hours once a week. There are several benefits of weekly 24-hour fasting. Some benefits include enhanced production of growth hormones and improved blood sugar levels.

  1. Fasting 2 days a week

Fasting 2 days a week is also called a 5:2 diet. 

People who follow the 5:2 diet usually eat for five days and then cut back on calories for the remaining two days.

According to a 5:2 diet-related study conducted on 107 overweight or obese women, it was found that following a continuous pattern of a low-calorie diet twice a week led to identical weight loss.

  1. Fasting 12 hours a day

According to many people, fasting for 12 hours each week is healthy because it gives their bodies a chance to rest and replenish themselves after the relentless digestion process. 

  1. Fasting 16 hours a day

Fasting 16 hours a day is also called the 16:8 or Leangains diet. In this type of intermittent fasting, individuals fast for 16 hours per day, followed by an 8-hour window during which they can eat.

  1. Warrior Diet

The warrior diet encourages only one meal at night. Even when you can eat during the daytime, there are certain restrictions.

How do I begin with intermittent fasting?

Don’t Rush. Start Slow. 

Before starting with intermittent fasting, it should be made clear what the main goal is and what you want to achieve with this fasting schedule. Secondly, another essential aspect to consider is what type of intermittent fasting would suit an individual. Last but not least, planning and preparing meals should also be a concern.

You may lead a successful journey of intermittent fasting, but a few things should be kept in mind and planned properly. Some tips for successful intermittent fasting include:

  1. Defining Personal Objectives
  2. Choosing a Suitable Method                                                        
  3. Calculating Your Calorie Requirements
  4. Staying Hydrated
  5. Exercising Regularly
  6. Listening to Your Body

Best foods for intermittent fasting

When following an intermittent fasting schedule, ensuring that your diet intake comprises nutrient-dense foods during your eating window is essential. This is particularly important to fuel your body and support your overall health. 

Focus on whole foods such as lean proteins, complex carbohydrates, and healthy fats. 

Choose lean proteins like turkey, fish, chicken, tofu, and legumes, which are essential for building and repairing muscle mass. You can incorporate healthy fats into your diet through nuts, seeds, olive oil, and avocados. These types of healthy fats play a significant role in improving hormone regulation and brain function. The sources of complex carbohydrates include quinoa, sweet potatoes, and whole grains. Complex carbohydrates are essential for sustained energy.

Last but not least, remember to include a proper intake of essential vitamins, antioxidants, and minerals in your diet. These nutrients play a significant role in supporting the body’s natural functions during fasting. 


Given the potential and scientifically proven anti-aging and other health benefits of intermittent fasting, it is worth considering this approach to promote better health and longevity. By selecting a suitable method for IF, taking nutrient-dense meals, incorporating exercise and activity, maintaining proper hydration and electrolyte balance, and being aware of what your body needs, you can successfully integrate intermittent fasting into your life. 

But wait! Just like beginning with any new medications or lifestyle changes, it is essential to consult with a healthcare expert before starting the journey of intermittent fasting. This is important to determine which type of fasting would be appropriate for a particular individual.
