Within the featured JJ Virgin Life-style Present podcast, I talk about my KetoFast protocol, which is the subject of my newest ebook by the identical identify. KetoFast is the time period I coined to explain a protocol that mixes three key methods: a cyclical ketogenic weight-reduction plan, intermittent fasting and cyclical partial fasting.
On this interview, I describe the best way to implement the KetoFast method, together with the meal timing and the categories and quantities of meals you need to be including to your plate.
“KetoFast” is the follow-up to my bestselling ebook “Fats for Gasoline,” and I strongly advocate implementing the methods specified by “Fats for Gasoline” first (which embody each day intermittent fasting and cyclical dietary ketosis), earlier than you progress on to “KetoFast,” through which you add partial fasting to every thing you’re already doing.
Why I Wrote ‘KetoFast’
As I clarify on this interview, the impetus behind “KetoFast” was two main realizations: First, that water-only fasting is a tremendously helpful well being intervention; and second, that whereas water-only fasting was once a perfect technique, the truth that trendy man is so poisonous makes it probably harmful to do prolonged water fasts for many.
We’re now surrounded by and uncovered to some 80,000 chemical substances in our surroundings, a lot of that are fats soluble, that means they accumulate in your fats cells. In the meantime, fasting successfully drives toxins out of fats cells, which may have devastating outcomes if you happen to’re severely poisonous.
What’s extra, because you’re not consuming, you’re additionally not offering your physique with the vitamins it must successfully neutralize and eradicate these launched toxins.
My reply to this dilemma was to plot — primarily based on the most effective scientific proof I might discover — a fasting program that mimics multiday water-only fasting, whereas supporting your detox pathways and minimizing the dangers related to toxicity.
The KetoFast protocol can be simpler to adjust to than multiday water fasting, and gives higher advantages since you’re in a position to do it extra incessantly. At most, you may do a five-day water quick 12 occasions a 12 months (as soon as a month). With the KetoFast protocol, you may do 42-hour fasts wherever between 50 to 100 occasions a 12 months.
The caveat is it is advisable to have executed at least a month of each day intermittent fasting and achieved dietary ketosis as specified by “Fats for Gasoline” earlier than you progress on to KetoFasting. When you’re metabolically versatile and might burn fats for gas, the mixture of cyclical dietary ketosis and cyclical fasting is phenomenal for weight reduction and optimizing your well being and longevity.
Consuming Too Steadily Creates Metabolic Dysfunction
In his ebook “Circadian Code: Lose Weight, Supercharge Your Power and Sleep Properly Each Evening,” Satchidananda Panda, Ph.D., cites analysis displaying that 90 % of individuals eat throughout a span of 12 hours a day, and many throughout even longer timespans. It is a prescription for metabolic catastrophe, and can radically enhance your danger for weight problems and persistent degenerative illness over time.
A part of the drawback is that while you eat all through the day your physique adapts to burning sugar as its main gas, which down-regulates enzymes that make the most of and burn your saved fats. If you happen to wrestle to shed weight, this might be a big a part of the issue — your physique has merely misplaced the metabolic flexibility to burn fats for gas.
The intermittent and partial fasting routine described in “KetoFast” basically mimics ancestral consuming patterns, permitting your physique to work optimally by permitting for intervals of breakdown and cleanout, and intervals of rebuilding and rejuvenation.
It’s notably essential to keep away from snacking or consuming a meal near bedtime. You actually wish to cease consuming a minimum of three hours earlier than you fall asleep, as feeding your physique at a time when it doesn’t want the vitality fuels the creation of free radicals as an alternative. Basically, late-night snacking is a prescription for persistent illness and early dying as it would impair your mitochondrial operate.
Current analysis1 exhibits males who eat supper a minimum of two hours earlier than bedtime have a 26% decrease danger of prostate most cancers, and ladies have a 16% decrease danger of breast most cancers than those that eat dinner nearer to bedtime.2,three This discount in most cancers danger is sensible when you think about the impact late-night consuming has in your mitochondria.
Persistent irritation is a trademark of most cancers, and by feeding your physique late at night time, the surplus free radicals generated in your mitochondria will merely gas that irritation. Mitochondrial dysfunction generally has additionally been proven to be a central drawback that permits most cancers to happen. To study extra about this, see “The Metabolic Idea of Most cancers and the Key to Most cancers Prevention and Restoration.”
Advantages of Fasting
The 2 main advantages of fasting, in my opinion, are stem cell activation and autophagy. Stem cells play an essential function in longevity as they’re instrumental in repairing and rejuvenating your cells and tissues, whereas autophagy is your physique’s innate cleanout course of, by which broken mitochondria, proteins and cells are digested and eradicated.
By upregulating autophagy and mitophagy (autophagy in your mitochondria)four and boosting stem cells you’ll decrease your danger of most illnesses, together with most cancers5 and neurodegeneration.6
Nutrient composition is essential right here, and within the ebook, I present particulars on the best way to optimize the autophagy and stem cell activation processes by consuming sure meals (and avoiding others) on the proper time. Apart from autophagy and stem cell activation, fasting is understood to offer many different well being advantages, together with:7,eight,9,10,11
Releasing ketones into your bloodstream, which assist protect mind operate and defend in opposition to epileptic seizures, cognitive impairment12 and different neurodegenerative illnesses
Boosting manufacturing of brain-derived neurotrophic issue, which stimulates creation of latest mind cells and triggers mind chemical substances that defend in opposition to mind adjustments related to Alzheimer’s and Parkinson’s illness13,14
Rising progress hormone by as a lot as 1,300 % in ladies and a couple of,000 % in males,15 thereby selling muscle growth and vitality
Reducing insulin and bettering your insulin sensitivity; research have proven intermittent fasting can each stop and reverse Kind 2 diabetes, which is rooted in insulin resistance16,17,18,19
Rising ranges of the neurotransmitter norepinephrine, which helps your physique break down fats for use as gas and advantages your metabolism20,21,22
Boosting mitochondrial vitality effectivity and biosynthesis
Reducing oxidative stress and irritation23
Enhancing circulating glucose24 and lipid ranges
Decreasing blood stress
Enhancing metabolic effectivity and physique composition, modulating ranges of harmful visceral fats and considerably lowering physique weight in overweight people

Enhancing immune operate26
Synchronizing your physique’s organic clocks27
Eliminating sugar cravings as your physique adapts to burning fats as an alternative of sugar
Rising longevity — There are a selection of mechanisms contributing to this impact. Normalizing insulin sensitivity is a serious one, however fasting additionally inhibits the mTOR pathway, which performs an essential half in driving the getting older course of
Abstract of KetoFast Protocol
The next is a abstract of my KetoFast protocol, which is, after all, expounded upon in my ebook. Step one is to compress your each day consuming window to 6 to eight hours for a minimum of 4 weeks, that means you eat your whole energy for the day throughout these six to eight hours, and for the remaining 16 to 18 hours, you’re fasting. That is your base.
When you’ve adopted this intermittent fasting schedule for a month — at which level you’ll have restored your metabolic flexibility to burn fats for gas — you may transfer into the second part, which includes having a single reduced-calorie meal, ideally breakfast, adopted by a 24-hour water-only quick, a couple of times per week.
This meal will sometimes be someplace between 300 and 500 energy. To find out what number of energy you must have at this meal, first calculate your lean physique mass by subtracting your % physique fats from 100. (So, you probably have 20% physique fats, you may have 80% lean physique mass.)
Then multiply that share (on this case, zero.eight) by your present whole physique weight to get your lean physique mass in kilos (or kilos). Subsequent, multiply your lean physique mass in kilos/kilos by three.5. That is the quantity of energy you’ll wish to eat for that meal.
Nutrient Ratios Throughout KetoFasting
By consuming simply that one 300- to 500-calorie meal after which fasting for 24 hours, you basically find yourself having eaten as soon as in 42 hours. This may successfully enable your physique to deplete the glycogen shops in your liver.
Even while you’re intermittently fasting for 16 to 18 hours, you continue to have loads of glycogen left, however while you quick for 42 hours, glycogen will likely be fully depleted, sending autophagy hovering. And, you may do that twice per week! Now, what ought to these 300 to 500 energy include? Ideally:
• Carbs — Lower than 10 grams of web carbohydrates (whole carbs minus fiber) in order to not replete your glycogen shops. Primarily, your carbs would then be nonstarchy greens, seeds or nuts.
• Protein — Half of your customized each day protein requirement. If you happen to’re youthful than 60, a normal advice for your each day protein requirement can be zero.eight grams of protein per kilogram of lean physique mass, or zero.5 grams of protein per pound of lean physique mass. Let’s say your each day protein requirement is 80 grams. For this meal, you’d minimize that in half to 40 grams.
The important thing right here isn’t just reducing your total protein consumption however relatively limiting your consumption of branched-chain amino acids resembling leucine, discovered primarily in meat and dairy merchandise.
The explanation you wish to limit branched-chain amino acids at this meal is as a result of they activate mTOR and inhibit autophagy — basically blocking the very cleanout course of you’re attempting to activate by means of fasting. You possibly can study extra about mTOR and autophagy in my interview with Dr. Jason Fung.
A great type of protein to incorporate on this meal is collagen, which gives nice help to your connective tissue. Chlorella is one other glorious protein you may embody.
• Fats — The rest of your energy come from wholesome fat resembling coconut oil, avocado, MCT oil, butter, olive oil and uncooked nuts.
After Your Quick, Feast!
The day after you’ve accomplished your 42-hour KetoFast is the proper time to do hardcore power coaching, and to load up in your protein. Instantly after is when you’ll wish to eat that grass fed natural steak and/or whey protein, as now you’re in rebuilding mode, so that you truly need and have to activate mTOR to construct new muscle mass.
As talked about, mTOR, governs progress and inhibits autophagy. On this means, KetoFasting lets you actually feast twice per week as nicely, which counters any emotions of deprivation you may need throughout fasting, and this will likely considerably enhance adherence.
