Intermittent Fasting For Healthy Aging
Fasting is one of the biological stressors that triggers autophagy a process where your body clears out dead or underperforming cells and regenerates and recycles damaged proteins.
Autophagy is extremely important and a natural process that plays a significant role in preventing diseases such as cancer, neurodegeneration, diabetes, cardiomyopathy, autoimmune diseases, liver disease and much more.
Regular fasting also puts an adaptive cellular stress on the body which in turn allows your body to cope with more severe stressors that may occur and thus protect against potential disease progressions.
This concept is known as hormesis when an exposure to a mild stress causes cells in your body to become more resilient against other, more severe stressors.
Many of the benefits of fasting are due to these essential physiological processes.
Similar to ketosis, IFs positive effects on aging are coming to light as more studies show that it has a profound ability to decrease blood pressure, reduce oxidative damage, improve insulin sensitivity and glucose uptake, and decrease fat mass all factors that contribute to enhancing health and longevity.
Choose The Right Fasting Method For Your Body And Goals
When youre deciding how to begin fasting, your unique psychology, metabolism, and physiology each play a role:
- If youre the type of person who prefers to jump in with both feet, you may find the challenge of extended or more difficult fasting patterns rewarding.
- If youre feeling a bit uncertain about fasting, or arent sure how your body will respond to fasting, ease in instead.
- People who struggle with hunger or get hangry should start with a minimal fasting approach .
- Anecdotally, men may have an easier time with prolonged fasts, while women may need to adjust their fasting strategy at different times of their cycles.
Before you choose a fasting strategy, be sure to think about the ways your mindset and your body may affect your fasting experience.
Most people should probably start with 16/8 or another less-challenging approach like non-daily fasting, but theres no one-size-fits-all recommendation for fasting.
Broadly speaking, heres how your goal choice may affect your intermittent fasting approach and duration:
Supplementation And Intermittent Fasting
Many people will make keto bulletproof coffee with MCTs, coconut oil, or ghee or butter. This promotes mental focus and satiety while still providing some of the benefits of fasting and ketosis. The term for this is called fat fasting and there are a great many people who follow this protocol and report similar effects to full-on IF.
Intermittent fasting is just one of many methods that can help you lose weight and lead a healthier life.

Research into the effects of fasting on fitness is early but promising.

Both groups had starting VO2 levels of around 3.5 liters per minute , which is close to standards for regular, untrained individuals. The study participants underwent endurance cycle ergometer training and had the following change in VO2 max:
In short, the fasted group increased their VO2max significantly more than those who were fed breakfast, which equates to a promising result for athletes and people who need aerobic fitness.

Another great perk of the keto diet is its high level of satiety.

This is perfect for someone doing intermittent fasting.

Lets find out.
What Is The Keto Diet
The keto diet is not a new diet to the market. It dates over 100 years ago to the 1920s. Keto stands for ketogenic. Keto is a shortened version of the original name.
The ketogenic diet was introduced many years ago as an epilepsy treatment. This was the then original keto diet. Epileptic patients found that carbohydrates made their symptoms worse. As it increased the risk of developing epilepsy, patients changed their diet to a 4:1 ratio of fat to protein and carbs. 90% of the keto diet calories were from fat. Then 6% from protein and 4% from carbs.
The keto diet is now often known for its many other health benefits. The ketogenic diet is often known for its weight loss and heart health benefits. As well as reducing cholesterol, treating brain disorders and lowering blood sugar levels.
The keto diet limits carbohydrate intake, which allows room for more fats and proteins. Which makes the ketogenic diet very beneficial for quick weight loss. Fat and protein are btoh incredible sources energy. Both improve energy endurance. They are also the reason for the diet being very beneficial for your health.
With the knowledge of the keto diet in mind, lets take a look into what intermittent fasting is:

How Long Should You Intermittent Fast
How long is intermittent fasting sustainable? When it comes to intermittent fasting for beginners, 24 hours or fewer is a safe limit.
Those more experienced with fasting may go 48-72 hours, or even longer however, youll have to experiment and work up to a long fasting window, and stop if it doesnt feel right or keeps you from doing daily tasks.
You can incorporate some form of fasting into your schedule every day, as long as you stay healthy and nourished with the right foods during your eating windows.
How To Combine Ketosis And Intermittent Fasting
In a nutshell, ketosis and IF are extremely complementary, but if youre new to both, you should probably start with one or the other.
Good news first: people who follow the keto diet can become fat adapted, which can make fasting much easier.
However, the potential for problems exists when people whove never tried a very low carb diet or fasted before combine the two strategies.
Issues like keto flu or trouble dialing in your keto diet can be made much worse by fasting, and the brain fog and lethargy some people experience early on during fasting can contribute to feeling worse on keto.
We recommend that you go keto first, allow your body to adapt to a healthy low-carb diet and produce ketones for at least a month or two, and incorporate fasting only after youve got a handle on the keto diet.
Done correctly, fasting on keto can help you break through weight loss plateaus along with all the other many health benefits mentioned previously in this article.
On the other hand, if youve already been fasting for several weeks or months but arent keto yet, you can consider adopting a ketogenic diet if fasting is comfortable for you.
But if youre not fully comfortable fasting yet, youd be better served by holding off on going keto until your body adapts to fasting.
Although going keto is beyond the scope of this article about fasting, dont miss the important insights about keto vs. fasting in the following sections.

Neurological Health And Mental Clarity
Ketosis and fasting are healthy for the human brain. When the ketogenic diet is followed, sometime within the first 30 days your body stops depending on glucose. This is because it is using stored fat for energy instead, and this state of ketosis is associated with enhanced mental clarity.
For this reason, certain experts believe that intermittent fasting improves a broad range of neuro-degenerative conditions, including stroke, Huntingtons disease, Parkinsons disease, and Alzheimers disease. After conducting a study on animals, researchers at the National Institute on Aging, found that cyclical fasting helps neurons in the brain to resist degeneration and dysfunction.
