Activating Autophagy
Activating Autophagy
The truth is that our bodies were created with an innate ability
to heal themselves. Every day, your body goes to work to help
repair damaged cells and cellular components while getting rid of
metabolic debris. Unfortunately, our society today has created
lifestyle habits that thwart this innate healing mechanism and
overload our system with metabolic waste.

Autophagy: What is It and 8 Ways to Enhance It
Autophagy happens when your body recycles and gets rid of old or excess cells
(like fat) that don’t serve a purpose or benefit your health. The major drivers of
autophagy are cellular stressors such as nutrient deprivation brought on from
various mechanisms including fasting, exercise and significant temperature change.
The Nobel Prize in 2016 was awarded to the Japanese researcher Yoshinori Ohsumi
for his breakthrough work in helping us understand the process of autophagy and
how it works. In this article, you will discover why autophagy is such an important
concept and how to structure your life to optimize its benefits in your life.

How Does Autophagy Happen:
The word Autophagy is derived from the Greek “Auto – Phagein” meaning “self
eating.” This is a form of cellular recycling where the cell itself will metabolize various
components in order to reuse those to build new and healthier cellular structures.
Within each cell there are a number of essential components called “organelles,” much
like the various organs that make up our body. The way autophagy works is when
the cell is exposed to stressors such as nutrient deprivation, it creates a transient
double membrane structure called a phagophore. The phagophore expands and has a
tremendous level of flexibility in regards to its ability to surround and sequester cellular
components such as proteins, lipids and whole organelles (1).
Once it surrounds and encloses the components it is after, it delivers them to the
lysosomes. The lysosomes are unique organelles that contain degrading enzymes to
degrade the particular components they are released upon.

The major driver of autophagy is cellular stress. Stress refers to an environment that
demands change. Our body is constantly looking for a level of physiological balance
called homeostasis which is necessary for survival.
During times of nutrient deprivation such as fasting, exercise, etc. the body needs to load
up on raw materials to fuel the metabolic machinery to produce the necessary energy
for survival. To do this, the innate intelligence within our body signals to break down the
older cells and cellular organelles that are working less efficiently to create newer cells
that work to produce energy more efficiently (2).
Benefits of Autophagy
It was very common for our ancestors to have stressful circumstances such as long
periods of time without food, high intensity activity and excessive heat and cold. These
demands stimulated a regular and healthy dose of autophagy within their cells.
The process of autophagy is occurring within all mammals at some level but creating a
lifestyle that optimizes autophagy can be extremely beneficial for a number of reasons.
Here are the top 5 reasons to support your body’s natural autophagy process.
| 5
Getting Rid of Senescent Cells:
All cells have a certain lifespan and younger cells have dealt with less wear and tear and
are more efficient in their particular functions. A senescent cell is an older cell that is not
functioning at a high level. It is still working but at a much lower level of efficiency and
not effectively enough to maintain the overall health of an organ or tissue of the body.
These cells are metabolically inflexible and have trouble using fatty acids for fuel.
They rely on sugar/glucose metabolism and produce energy very inefficiently
and create a lot of metabolic waste and produce cell signaling factors that
promote inflammatory conditions in the body.
These are cells put the entire body at risk of the development of disease processes
because of their dysfunction. While the development of senescent cell is a normal
process, we should be removing these as fast as we create them through autophagy
(3). As people age, we develop more of these decaying cells and therefore, the
stimulation of autophagy is even more critical for the wellbeing of the individual.
| 6
Improving Mitochondrial Health
Within a cell we have mitochondria which are unique organelles that produce cellular
energy. A healthy mitochondrion can use both glucose, fatty acids and ketones for fuel.
When we train our body to create a large amount of energy from glucose, we end up
producing a lot of free radicals and metabolic waste that damage the mitochondria.
Unless regular bouts of autophagy are stimulated, we end up with a large number of
dysfunctional mitochondria that are metabolically inflexible and can only rely on glucose
for fuel. Autophagy may keep the cell in tact but degrade the dysfunctional mitochondria
and reuse the raw materials to form new, metabolically flexible mitochondria. This
process of mitochondrial recycling is called mitophagy (4).
| 7
Eliminating Viral Infected Cells
Viruses are different than other pathogens in that they are intracellular as opposed to
bacteria, yeast and parasites that live in tissues and organ systems of the body. Viruses
get inside of cells and impact the metabolism and expression of the cellular genetics.
While a strong immune system helps to turn off viral expression and put them into a
dormant state, it doesn’t actually get rid of these cells. The cells continue to replicate and
continue to pass the viral material to new daughter cells. When the body is under more
stress and the immune system is more susceptible, the viral activity can increase and
cause wide range of cellular disruption.
A few examples would be the Varicella-Zoster virus which causes chicken pox in children
and triggers Shingles in adults. The individuals who experience this harbor the virus
from childhood and experience shingles outbreaks at times as an adult when they are
under more stress and unable to adapt effectively.
| 8
Autophagy is the way the body naturally eliminates these infected cells and reduces
viral activity in the body (5). In fact, when you experience viral challenges, such as getting
the flu, you often lose your appetite and even water makes you feel nausea.
This is actually a way the body induces a fast (in some cases a dry fast if you cannot keep
water down), stimulates autophagy and dramatically reduces the viral count in order
for the body to adapt and get better. Following a fasting lifestyle is a great way to keep
your viral infected cells at a low level and help your body maintain its optimal genetic
expression.
| 9
Reduces Cellular Apoptosis:
Older cells will often undergo a programmed cell death called apoptosis. This process
causes of a lot of metabolic waste that can be stressful on the body and induce
inflammation. Autophagy on the other hand is a very clean and energy efficient process
(6).
The more cells that are able to repair themselves before they because permanently
damaged the less inflammation and metabolic waste is produced. This recycling process
is very clean and smooth for the body and conserves energy for other vital functions and
help us feel significantly better in our mind and body.
I think of the cellular apoptosis mechanism as a backup way the body eliminates diseased
cells. If we are over-reliant on this back-up mechanism then there are too many things
that could go wrong.
As an example, high levels of oxidative stress block the p53 gene that governs cellular
apoptosis. When this happens, we can no longer regulate cell division and overtime we
develop various cancer (7).
| 10
Autophagy Creates a Stronger and
More Stress Resilient Body and Mind
All the above-mentioned benefits of autophagy work together to help us have a stronger
and more stress resilient body and mind. For example, autophagy in our muscle cells
makes them stronger and more resilient to wear and tear.
Autophagy in our intestinal lining makes us less susceptible to gut inflammation and the
formation of leaky gut syndrome. High levels of regular autophagy on our skin makes it
more resilient and less likely to develop eczema, acne and signs of aging.
Autophagy in our brain cells helps them function sharper and quicker which gives us
better mood, memory and mental processing. It also dramatically reduces our risk of
developing dementia and other neurodegenerative conditions (8).
As you can see, doing things to promote autophagy can be one of the most powerful
health strategies you apply into your life. Here is how to maximize the balance between
autophagy and growth signaling in your body.
| 11
AMP-K and mTOR Pathways
In order to activate autophagy, you must suppress insulin and Mammalian Target of
Rapamycin (mTOR) and activate the AMP-K pathway in your body. The mTOR pathway is
associated with the regulation of growing tissues in the body.
Temporary mTOR elevations are great for building muscle and fat burning, chronically
elevated mTOR is associated with an increased risk of chronic disease and cancer.
| 12
Glucose to Ketone Ratio
The Glucose Ketone Index, or the GKI, is a ratio that researcher Dr. Thomas Seyfried has
been using in his studies looking at tumors and how they respond to both fasting and the
ketogenic diet (9). A healthy nutritional ketosis marker for the GKI is between 1:1 and
4:1. If you are in this zone, you are in nutritional ketosis and your body is either learning
how to use ketones for energy or has adapted and is using them as a primary energy
source.
However, when it comes to brain tumors and other cancers, Dr Seyfried and his
colleagues have found a ratio close to 1:1 to be most effective. The target zone for this
is when the glucose numbers are in the 60’s and the ketones are roughly 3.0 mmol/L or
more. You can get to these levels through the water fast and typically by Day 4-5, most
people will be hovering in this range.
The GKI is found by taking the blood glucose level and dividing it by 18. You then take
that number and divide it by the blood ketone level. A blood sugar of 64 with ketone level
of 3.1 would have a GKI of 1.15
According to Dr Seyfried, a GKI of 1:1 is the most effective level for shrinking tumors.
This is due to the rampant amount of autophagy that takes place and the lack of insulin
and available glucose that tumor cells use to grow and divide. If you are hitting close to a
1:1 GKI than the body is going to work on these destructive cells.
Your blood glucose will typically be at its highest in the morning due to higher cortisol
levels but should drop as the day goes on. Stress will cause it to go up higher so do your
best to limit the amount of stress you are under.
| 13
Intermittent and Extended Fasting
Fasting for extended periods of time is by far the most powerful way to stimulate
autophagy mechanisms in the body. You will achieve peak levels of autophagy around
Day 4 and 5 of a water fast when your glucose-ketone index (GKI) is around 1:1.
Another approach is to do a partial fast for 5 days each month or two. One researched
example of a partial fast is the Fasting Mimicking Diet, which has the individual consume
between 800-1100 calories for 5 days and has powerful studies behind its impact on
autophagy (10).
However, you can also stimulate a healthy level of autophagy through daily intermittent
fasting where you restrict meals to an 8 hour or less window each day (11). This would
mean you would fast for 16 hours without taking in any calories each day. As an example,
you could eat your meals between 10am – 6pm.
| 14
The Benefits of Feasting
Although fasting is the greatest stimulator of autophagy, we also need to stimulate the
mTOR and insulin pathways in order to build and produce energy on a regular basis. Too
much autophagy, as witnessed in individuals who are on a long-term calorie restricted
diet leads to muscle wasting, depressed thyroid and sex hormone activity (11).
What is built into our DNA from ancestral times is a feast-famine cycle of eating. Our
ancestors ate until they were full when they ate due to a lack of consistent food supply
and a lack of refrigeration and other modern food storage strategies.
Food wasn’t guaranteed and they would frequently go days with little to nothing to eat.
When they did have food available, the idea was to eat as much as you could so you could
get your share as the food would spoil quickly.
When we periodically feast on healthy nutrient dense foods, we flood the body with key
nutrients it needs and we also stimulate metabolic pathways that help us to burn fat for
fuel and have proper lean body tissue development.
| 15
The key principle to remember is that when we fast…we fast and when it is time to eat…
we feast until we are full and satiated. This balances the body between the physiological
mechanisms behind both building and cleansing the cells.
In this section, I will briefly explain how these strategies will support your body’s ability to
stabilize blood sugar, burn fat and improve autophagy and cellular repair.
| 16
Follow a Ketogenic Diet
Most people in society are burning sugar in the form of glucose as their primary energy
source. When we are in this sugar burning mode, we end up with large blood sugar
fluctuations and higher insulin levels. This physiological process inhibits autophagy.
A ketogenic diet is a high fat, low carb and moderate protein nutrition plan. This pattern
of eating lowers blood sugar and insulin levels and causes the body to adapt to burning
dietary fat and its own body fat for fuel.
Ketones are byproducts of fatty acids that are more easily used to produce cellular
energy and they can cross through the blood brain barrier to fuel the brain. Ketones are a
preferred fuel for the body because they produce significantly more energy per molecule
than glucose and they produce a lot less metabolic waste. They are a clean fuel source as
opposed to the dirty fuel produced by burning sugar.
A ketogenic diet mimics fasting and you get some of the same benefits of fasting while
still eating food. By blunting insulin, the ketogenic diet primes autophagy pathways and
when we apply intermittent fasting, we get into a state of autophagy much quicker than if
we were not keto adapted.
| 17
Drink Green Tea or Black Coffee
Green tea can help overcome a common weight loss roadblock: slow metabolism. For
a lot of people, once they’ve lost a certain amount of weight, their metabolism slows
down. With a slow metabolism, calories you consume are used more slowly and are more
likely to be stored… and the rest of the fat you’d like to lose stays right where it is. The
polyphenols in green tea, also known as catechins, counteract that slow metabolism by
| 18
boosting your energy expenditure (12). Drinking enough green tea provides catechins
needed to use more energy.
Green tea catechins also help to regulate ghrelin, otherwise known as the hunger
hormone (13). If you struggle with fasting because of hunger pangs, green tea can reduce
those pangs and help make your fast more successful.
In fact, a number of different plant polyphenols and nutrients have the power to make
fasting a more pleasant experience. Mint and licorice root are known for their ability to
reduce appetite. Ginger has anti-inflammatory benefits and can soothe your stomach,
while citrus peel helps digestion and can even boost autophagy.
In addition, if you are a coffee drinker, then I have good news. Black coffee has been
shown to help induce autophagy (14). My experience is that only about 66% of the
population does well with coffee or caffeine in general and the other 3rd struggles with it.
The way you know you are getting a positive response is if you feel good after the next
few hours after drinking it on a fast. If you feel anxious, irritated, or have an increase in
hunger and cravings than it is a sign you are having a poor response.
| 19
Use Anti-Inflammatory Herbs
Just like green tea, many herbs contain unique plant compounds called polyphenols.
These polyphenols act to suppress the mTOR pathway and activate the AMPk pathway
to induce autophagy (15, 16).
This isn’t as strong a stimulus towards autophagy as fasting but it can be used in
conjunction with fasting and the other strategies in this article to optimize the autophagy
mechanisms in your body.
Some of the best herbs for this include quercetin (red onions and elderberries), carnosic
acid (oregano, sage and rosemary) citrus bergamot (Earl Gray tea), ECGC (green tea and
dark chocolate), 6-shagaol (ginger), curcumin (turmeric) and resveratrol (blueberries,
grapes and red wine) among others.
Getting these compounds by consuming a number of herbs in our diet and through
supplementation can be very helpful. In addition, I am a huge fan of drinking herbal teas
made from many of these compounds.
| 20
Drink Apple Cider Vinegar
You can also choose to drink an apple cider vinegar (ACV) tonic during your fasting
window. ACV contains a compound called acetic acid, which helps boost your metabolism
and burn fat rather than store it (17).
Apple cider vinegar is also shown to be useful in making you feel fuller for longer and
reducing your appetite. When paired with starchy foods, ACV can slow digestion. While
digestion is happening, you remain feeling full. While your body is digesting that food,
your insulin levels should remain stable, meaning you won’t feel tempted to reach for a
sugary snack.
We recommend diluting 1-2 tbsp of ACV in water and drinking it before meals.
| 21
Do High-Intensity Interval Training (HIIT)
and Resistance Training
High intensity interval training and resistance training while fasting can ramp up
autophagy, stimulate fat burning and improve mood and mental focus. Fasting and
exercise both create an environment of stress for the body. That might not sound very
appealing in theory, but intermittent doses of that stress can help with weight loss and
improve mental clarity.
Exercise in a fasted state of 12-16 or more hours also helps increase the autophagy
signaling mechanisms as the body senses it needs more nutrients to produce energy. As
muscle cells are being damaged during the exercise, the body goes to work breaking the
cellular material down and rebuilding it (19).
High intensity exercise and resistance training help stimulate human growth hormone
(HGH) which creates an environment that favors fat burning, autophagy and muscle
tissue repair and preservation. The boost in HGH is higher when the individual is in a
fasted state.
I recommend working out in the morning or mid-day on a 12-16+ hour overnight fast. You
should be well hydrated and you can take in a pinch of salts for electrolytes and consume
some green tea or organic black coffee if you like.
If you are new to fasting, begin with exercise on a 12 hour fast and have a good quality
protein shake after your workout. If you have had a lot of success with fasting you can get
a great workout after 16-24+ hours of fasting and then replenish with a good meal after
the workout.
| 22
Prioritize Good Sleep for Autophagy
We all know how important sleep is and so it should be no wonder that our sleep cycle
and circadian rhythm is intimately tied into autophagy (20). Individuals with circadian
rhythm disorders due to poor sleeping habits, insomnia and long-term night shift work
have an increased risk of early-onset chronic disease development.
One of the reasons for this is that autophagy is in part regulated by light & dark cycles
and deep sleep favors an environment for optimal autophagy mechanisms. You will need
to prioritize good sleeping habits in order to help your optimize autophagy with your
intermittent and extended fasting regimen.
| 23
Use Heat and Cold Strategically for Autophagy
Short periods of intense heat and cold exposure have also been shown to promote
autophagy mechanisms (21). Rapid temperature changes are a major stressor on our
body and we have to adapt quickly to get back to balance and homeostasis.
This is one reason why stressed out people often get sick with colds, infections and the
flu when the temperature drops outside. Their body was already stressed and immune
susceptible and when the weather changed quickly it overwhelmed their body and made
it hospitable to environmental pathogens.
| 24
This adaptation pushes autophagy and gives us a much greater ability to adapt to
temperature changes and other stressors we encounter. In essence, strategic dosing of
hot and cold temperatures makes us stronger and more resilient human beings.
Some ways to take advantage of this are to exercise outside in the heat of the summer
or use a steam sauna or what I do personally, an infrared sauna on a regular basis. For
cold adaptation, I like to finish my daily shower with 1 minute at the coldest temperature
possible.
I pump my arms and legs in order to activate my skeletal muscle when this is going on
and it gives a great boost to circulation and feel good compounds such as serotonin,
dopamine and endorphins.
| 25
Temporary Caloric Restriction
& Protein Restriction
While protein is essential for muscle building, bone density, fat burning, brain and heart
health, too much protein in your diet can increase insulin, block ketone production,
and activate the mTOR pathway. Research has linked caloric restriction and protein
restriction to the activation of autophagy (22, 23).
Adding protein to your diet (during your eating window, of course), is very important for
balancing out the benefits of autophagy with proper building mechanisms so your body is
strong and healthy.
Driving up autophagy for a prolonged period of time can cause many issues I discussed
already in the section on feasting. Protein is vitally important to the mTOR pathway to
build up strong cells. The mTOR building and the AMP-K autophagy pathways need to
be in balance for most individuals and applying intermittent fasting along with periods of
feasting and good quality protein intake creates this appropriate balance.
Eating protein helps those muscle cells stay healthy. It feeds muscle cells so they’re
able to repair any microscopic damage that’s made during exercise. Each time they’re
repaired, they get a little bigger. As long as they’re being repaired, your body won’t see
them as cells that it needs to get rid of, and will opt for other cells, like fat, instead.
| 26
Best Sources of Protein
Use the chart below to determine your daily protein range based around the specific goals
you have. Our bodies can handle periods of extended fasting with protein or any calories,
but I wouldn’t recommend any more than one extended fast of 5 days or more per month
unless you are under strict medical supervision.
For protein sources, it is best to choose organic, pasture-raised meats, eggs, dairy and
wild-caught fish. You can also use plant-based protein sources such as nuts, seeds and
legumes.
| 27
I am also a huge fan of adding a good quality bone broth or collagen protein powder into
your diet to get more connective tissue amino acids into your body. You can also use
a vegan based protein source such as pea, hemp, chia or rice protein to support your
protein needs.

Top 7 Herbs That Enhance
Autophagy and Cellular Healing
One way to enhance autophagy and cellular healing is by using specific herbs.
Many herbs contain polyphenols that help to suppress the mTOR pathway and
activate the AMPk pathway to introduce autophagy.
| 29
Matcha Green Tea
Matcha green tea is an increasingly popular tea. Though it comes from the same
plant, Camellia sinensis, as green tea, it is grown differently. Farmers cover the tea plant
for 20 to 30 days before harvesting. This technique increases chlorophyll production and
amino acid content. After harvesting, they remove the stems and veins to create a fine
powder from the ground up leaves resulting in a tea that’s higher in antioxidants than
green tea.
Matcha green tea is rich in the polyphenol ECGC and has a number of health benefits.
One of its benefits is enhancing autophagy by mimicking the effects of calorie restriction.
Some even refer to matcha as the autophagy-tea. Other benefits include boosting brain
function, supporting your liver, protecting your heart, and helping weight loss (27).
| 30
Use Ginger To Enhance Autophagy
Ginger is one of the most potent anti-inflammatory herbs out there. It belongs to the
rhizome family, which means that its stem grows horizontally grows underground
forming roots downwards and stems and leaves above ground.
It has been used for over 5,000 years in China and India as a natural remedy. Since the
Roman Empire, it has also been popular in Europe and in the past several hundred years
around the world, including the United States. It can be used in dishes, teas, and juices,
and as a supplement.
Ginger has over one hundred chemical compounds. Gingerol is its most powerful active
compound with a variety of powerful health benefits. Ginger may enhance autophagy,
decrease inflammation, and lower pain levels. It has been shown to reduce inflammation
and pain related to exercise, osteoarthritis, intestinal issues, metabolic syndrome, and
obesity (28, 29, 30, 31, 32).
| 31
Turmeric
Just like ginger, turmeric is an anti-inflammatory herb that belongs to the rhizome family.
It is a warming spice that provides flavor and color to various foods, condiments, and
teas. It has been used for thousands of years in traditional Ayurvedic, Indian, and Chinese
medicine, and more recently as an anti-inflammatory supplement around the world (33).
Turmeric is one of the most researched spices. The US National Center for Biotechnology
alone has over 6,000 studies on its benefits. It is a powerful anti-inflammatory and
antioxidant herb with a potent active compound, curcumin.
Turmeric may enhance autophagy, decrease inflammation, and lower pain levels.
Research has shown that turmeric may benefit inflammation related to ulcerative colitis
diabetes, osteoarthritis, and lupus (34, 35, 36, 37, 38, 39).
| 32
Use Resveratrol To Enhance Autophagy
Resveratrol is a powerful plant compound that can be found in red wine, grapes, berries,
and peanuts. It is mainly concentrated in the skins and seeds of grapes and berries, which
explains that the fermented grapes in red wine are particularly high in resveratrol.
Resveratrol acts as an antioxidant with countless health benefits for your health.
Research has shown that by directly inhibiting mTOR through ATP competition,
resveratrol may enhance autophagy. It may also be beneficial for brain health, insulin
sensitivity, blood pressure, and joint pain (40, 41).
| 33
| 34
Citrus Bergamont
Citrus bergamot is a unique orange-sized fruit. It’s yellow-green and bitter. It has been
used as an aromatic essential oil for a long time, and it’s an ingredient of Earl Grey tea,
traditional colognes, and other things.
Citrus bergamot is rich in antioxidant flavonoids that offer fantastic benefits for
your health, heart health, and cholesterol. It may enhance autophagy, especially skin
autophagy. As aromatherapy, it may benefit pain, anxiety, nausea, and vomiting (42, 43).
| 35
Quercetin To Enhance Autophagy
Bioflavonoids, or flavonoids, are a group of pigments that may help to protect you against
various diseases. They possess anti-inflammatory, antioxidant, anti-viral, anti-allergic,
and anti-carcinogenic properties, and may enhance autophagy.
While there are over 4000 known bioflavonoids, quercetin is one of my favorites.
Quercetin can be found in onions, leafy greens, tomatoes, broccoli, and berries. It
may enhance autophagy, fight inflammation, improve immunity, and fight free radical
damage (46).
| 36
Use Inflam Defense™ To Enhance Autophagy
Inflam Defense™ is one of my favorite supplements to enhance autophagy and cellular
healing. It uses the powerful combination of anti-inflammatory herbs, such as turmeric,
boswellia, ginger, and rosemary extracts, as well as nutrients from quercetin, rutin, and
proteolytic enzymes.
Inflam Defense helps to enhance autophagy, support your immune system, protect you
against oxidative stress, support healthy circulation and circular function, and boost your
health with antioxidants.
If you are looking to enhance autophagy, keep your inflammation and pain levels under
control, boost your immune system, and support your overall health, I recommend Inflam
Defense™. Take one capsule twice a day between meals. For advanced protection, take
two or more capsules between meals or as directed by your healthcare practitioner.

Feast Famine Cycling: Autophagy,
Cleansing and Muscle Growth
Feast famine cycling is an eating concept derived from our ancestral roots. More and
more people are interested in fasting for its health benefits. However, many forget about
the importance of feasting.
While fasting certainly has a number of health benefits, including fat burning, reduced
inflammation, and improved energy levels, prolonged calorie restriction also has a
downside to it, including potential hormonal imbalance. This is why feasting is so
important.
Through feasting, you can nourish your body with nutrient-dense foods. Feast-famine
cycling can help to regulate cell-growth and cleansing pathways, create hormonal
optimization, boost lean body tissue development, better inflammation and immune
activity, and enhance mental health and emotional well-being.
| 38
In this article, you will learn about the benefits of fasting, the importance of feasting,
feast-famine cycling, and hormone balancing. You will also learn how to implement feast-
famine cycling to receive full benefits from your fasting lifestyle.
Benefits of Fasting
Regular fasting and intermittent fasting can have incredible benefits for your health. It
can improve your life physically, mentally, emotionally, and spiritually.
| 39
Some of its top benefits include:
• Stimulating fat burning (47, 48, 49, 50)
• Improving energy levels (51, 52)
• Reducing inflammation (53)
• Taking stress off the digestive system (54)
• Stimulating cellular autophagy (55)
• Improving genetic repair mechanisms (56)
• Stimulating the development of stem cells (57, 58)
• Improving insulin sensitivity (59)
• Reducing the risk of chronic disease (60)
• Improving your relationship with food
• Enhancing mental health (61)
• Spiritual growth and fine-tuned intuition
| 40
Why Feasting is Just as Important
While fasting is a highly effective way to stimulate autophagy, you have to remember
that feasting is just as important. Too much autophagy can become a problem as well. You
need to stimulate the mTOR and insulin pathways to produce energy on a regular basis.
Long-term calorie restriction can lead to too much autophagy, which can result in muscle
wasting, as well as compromised thyroid and sex hormone activity (62).
Feast-famine cycling can help to regulate cell-growth and cleansing pathways, create
hormonal optimization, improve lean body tissue development, balance inflammation,
and immune activity, enhance mental health and emotional well-being. Fasting is a time
for cell cleansing and healing, whereas feasting is a time for growth, rebuilding, and
reproduction.
Our ancestors went through a feast and famine cycle regularly and it is literally built into
our DNA. Our ancestors didn’t purposely fast, but simply didn’t eat when food wasn’t
available during a famine. However, they feasted or ate until they were full when food was
available.
Back in the day, refrigeration and other modern food storage techniques were not
available, and they never know when the next meal would come. Since food wasn’t always
guaranteed, and they would frequently have to go without food for days, your ancestors
used the opportunity to feast and rebuild their energy from nutrient-dense food
whenever they could.
| 41
Cycling Through Feast Famine Periods
Intermittent fasting and other forms of fasting are utilizing your body’s ancient wisdom
in your DNA carried on from your ancestors. If you want to take care of your body the
way it was designed to, through fasting, it is important that you are equally focusing on
both fasting and feasting.
When you are feasting on healthy, nutrient-dense foods, you flood your body with
essential nutrients it needs to repair and create health. You stimulate metabolic
pathways that are needed to burn fat for fuel and have proper lean body tissue
development.
What you need to remember is that you need to create a healthy balance between
fasting and feasting. When you are fasting, fast, don’t cheat with small snacks here and
there. However, when it’s time to eat, feast until you are full and satisfied. Don’t overeat,
but don’t limit yourself. Satisfy and nourish your body with much-needed nutrients from
healthy foods.
| 42
Feast Famine Cycling and Hormone Balance
When you are practicing intermittent fasting, it is essential that you are practicing
feast-famine cycling for hormone balance. Prolonged calorie restriction can be hard on
your body and disrupt your hormones, including your insulin, thyroid, adrenals, and sex
hormones. Feasting can show your body that it’s safe and prevent hormonal problems.
Insulin
Continuously stimulating your insulin hormones is not
ideal, instead, you want to raise it strategically. You
don’t want your body to think that it’s starving long
term. Raising your insulin levels strategically through
feast-famine cycling tells your body that you are not in
starvation mode. This can help to convert inactive T4
and active T3 thyroid hormones as well and create a
healthy balance within your body.
Thyroid
Prolonged calorie restriction can be stressful on your
body. It can lower active thyroid hormone levels, slow
your metabolism, and cause hypothyroid symptoms. On
the other hand, feast-famine cycling can help your body
to balance this problem, and maintain optimal thyroid
functions (63).
| 43
| 44
Adrenals
Prolonged calorie restriction can make your body
to release more cortisol than normal, thus put more
stress on the body, and lead to elevated cortisol levels,
sleep problems, fatigue, slow recovery, muscle fasting,
and adrenal fatigue. Feast-famine cycling can help
your body to balance your hormone levels and prevent
adrenal fatigue (63).
Sex Hormones
Prolonged calorie restriction puts stress on your body
and may tell the body that the conditions are not good
to reproduce. To protect your body and prevent the
development of a future baby under unsafe conditions,
your hormone levels may decline. Female bodies
are particularly sensitive to calorie restriction and
restrictive diets.
When your sex hormones are not functioning well, they cannot communicate with the
ovaries in females, which may result in irregular periods, amenorrhea, infertility, poor
bone health, and reduction in ovary size. Underproduction is sex hormones can cause a
loss of lean body tissues, libido, mental and physical drive in all sexes (64, 65, 66, 67).
Feasting intermittently helps your body understand that food is prevalent, it is available
at regular cycles, and the conditions are good. It helps you to get the full benefits of
reduced inflammation and increase autophagy through a feast and famine cycle with
proper hormone balance for mental and physical performance.

How to Implement Feast Famine Cycling
When you are practicing intermittent fasting, it is important that you remember that
the goal is not necessarily to eat less overall, just to simply eat less often. I’m not a fan of
counting calories. It is better to listen to your body cues and needs and fill up on nutrient-
dense foods until you are satisfied.
However, if you find that you are struggling with this approach, it may be helpful to know
that you are under- or overeating with the help of temporary calorie counting.

Your body has been burning sugar their entire life; hence it may have a poor ability to
burn fat at the cellular level. Jumping into keto too quickly can put you in a limbo where
your blood sugar levels are too low but you can’t effectively burn fat for energy yet. This
can lead to a variety of unwanted side effects we refer to as keto flu, such as low energy,
dizziness, and more.
However, if you adopt the keto diet slowly, you can avoid these side effects and improve
your metabolic flexibility. Even if you are completely new to keto, this gradual approach
of shaving of carbs slowly allows your body to fat-adapt effectively.
During your first week on keto, reduce your carbs during the daytime and focus on
healthy fast instead. In the evening, you can add some healthy carbs, such as one sweet
potato or one cup of carrots. The second week, reduce your evening carb intake by half to
half a sweet potato or half a cup of carrots.
For the next two weeks, stick to 70 percent fat, 25 percent protein, and 5 percent carbs
in your diet. With this gradual approach, you will be set to live a ketogenic lifestyle.
Overtime, you can also implement carb cycling strategies after you have developed the
metabolic machinery to get into ketosis.

Avoid Snacking
The feasting and famine cycle is a way to tap into your body’s wisdom and improve your
health. Your ancestors didn’t have snacks handy either during a famine, neither should
you snack during the fasting cycle.
Your fast is a period to improve autophagy and cellular renewal. If you reach for snacks
during your fasting window, you are essentially breaking your fast. This can lead to blood
sugar issues, digestion problems, and you won’t be able to experience the benefits of your
snack.
You should also avoid snacking during your feasting period. Depending on the type of
intermittent fasting you are practicing, you may have one, two, or even three meals
during your feasting period. In order to meet all your nutrient needs from high-quality
foods, it is best to eat enough during your meals, so you don’t go hungry in-between.
If you are feeling hungry between meals or during your fasting window, it is a good idea
to look at your caloric and nutrient intake and adjust it accordingly to avoid under eating.

Develop Your Fasting Muscle
If you’ve been used to eating three meals and three snacks a day and eating late at night,
an advanced fasting regiment can be a shock to your body. Teaching your system to thrive
through feast-famine cycling is similar to beginning a new exercise program. It has taken
time to become adapted to fasting, and a gentle, gradual approach is key to develop your
fasting muscle and create a new routine.
I recommend that you start gently and get used to fasting gradually. Instead of jumping
into OMAD (one meal a day) or 2 or 3-day water fast, start with a Simple Fast with a
shorter, 12-hour fasting window.
Once that becomes easy for you, you can reduce your eating window and add more
fasting days to your weekly schedule using Crescendo or Cycle Fasting. Gradually tighten
up your eating window as long as you feel good. If you are ready, you can eventually move
up to a daily intermittent fasting schedule.
| 50
Improve Hydration During Fasting Window
Proper hydration is absolutely critical during your fasting window. During your fast, your
body will lose a lot of water when using up stored glycogen in your muscles and liver.
As your insulin levels drop, you may use more water and sodium than normal. If you get
dehydrated during your fasting window, you are more likely to feel tired, dizzy, achy, and
constipated.
I recommend that you drink 32 oz water upon waking during the morning of your fast and
drink continuously during the day. Adding a pinch of Himalayan sea salt or Celtic salt to
your water is helpful to replenish your electrolytes. Adding some lemon or lime to your
water add extra vitamins and minerals, and help detoxification and digestion.
| 51
Regular Exercise
Regular exercise can enhance the benefits of intermittent fasting. Regular movement can
help you build muscles, improve your flexibility, improve your cognitive ability, boost your
mental health, and reduce your risks of various diseases, such as Parkinson’s disease,
multiple sclerosis (MS), and cancer (70, 71, 72, 73, 74).
Strength training, such as weight lifting and body weight exercise can help you to build
and hold onto your muscle. Resistance training can improve your strength, flexibility, and
motor control. High-intensity training (HIIT), interval training, circuit training, and sprints
are a fantastic way to increase your muscle mass.
HIIT is particularly great because it combines cardio and strength training in one short
workout. During your fasting window, I recommend sticking to low-impact exercises,
such as yoga, pilates, and light walks.
| 52
Improve Digestive Health
If you are used to eating smaller meals or snacking throughout the day, feasting during
a shorter eating window than before may be difficult on your digestive system at first. If
you’ve been dealing with digestive problems or have been living on too much junk food
with refined sugar and refined fats, chances are your digestion needs a bit more support
to function optimally during the feast-famine cycle. I recommend that you support your
digestive system with some high-quality herbs and supplements.
Eating high fiber foods, such as nuts, seeds, greens, and non-starchy vegetables can help
you to be regular if constipation is a concern. Bitter herbs, such as ginger, parsley, fennel,
basil, thyme, and oregano are a fantastic way to stimulate your digestive juices.
Add them to your cooked meals, salads, and green smoothies, and look for supplements
with them. Drinking apple cider vinegar (ACV) mixed with water or lemon water before
meals can enhance digestion and absorption, and reduce the risk of bloating and acid
reflux.
| 53
Consider Digestive Health Supplements
It is important that you support your digestive system with some high-quality
supplements when feasting. Taking digestive enzymes can help your body to digest your
food and absorb your nutrients easier and more effectively. I recommend taking Super
Dzyme or Keto Digest which are powerful groups of plant based enzymes to help the
body digest and assimilate nutrients better. Consider the use of the use of stomach acid
support, such as Acid Pro-Zyme if eating meat gives you digestive challenges to lower the
risk of acid reflux and indigestion.
We know that stress is the antagonist to good digestive juice production and is the
biggest factor to causes digestive challenges. It is important to be in a relaxed state when
you consume your meal so that your body can produce the digestive juices it needs.
