Breaking Down Myths About Fasting
“The Complete Guide to Fasting: Heal Your Body Through Intermittent, Alternate-Day, and Extended Fasting,” co-authored with Jimmy Moore, particulars how to implement fasting and overcome a few of the commonest challenges which may come up, together with persistent fears and myths related to prolonged water fasting.
Dr. Fung’s new guide is very useful as a result of it supplies easy-to-follow primary tips for fasting, and evaluations a number of the commonest myths and fears that maintain many from implementing a fasting routine.
A standard fable is that fasting will lead to lack of muscle mass. Dr. Jung’s e-book clearly describes the method of protein catabolism, explaining how your physique truly downregulates protein catabolism and upregulates progress hormones in response to fasting.
“In case you comply with the biochemistry, your physique shops power as glycogen within the liver, which is hyperlinks or chains of sugar, after which it shops [it as] physique fats.
Throughout fasting, you begin by burning off all of the glycogen within the liver, which is all of the sugar. There’s some extent there the place a few of the extra amino acids in your physique want to get burnt as properly.
That’s the place individuals say, ‘That’s the place you’re burning muscle.’ That’s not truly what occurs. The physique by no means upregulates its protein catabolism. By no means is it burning muscle; there’s a traditional turnover that goes on.
There is a specific amount of protein that you simply want for a daily turnover. If you begin fasting, that begins to go down after which fats oxidation goes means up. In essence, what you’ve carried out is you converted from burning sugar to burning fats. When you begin burning fats, there’s virtually a vast quantity of energy there. You would go for days and days.
What’s fascinating is that for those who take a pound of fats, that’s roughly three,500 energy. When you eat someplace round 1,800 to 2,000 energy a day, it takes two full days of fasting to burn a single pound of fats, which is very shocking to individuals.
For those who’re making an attempt to lose 100 kilos, you may theoretically go 200 days of fasting simply to burn all that fats … Individuals fear about fasting for 24 hours. I’m like, ‘You could go 200 days.’ Then it’s like, ‘OK. Maybe it’s OK to go 24 hours with out consuming.’”
The ‘Starvation Mode’ Fable
One other widespread worry is that fasting equals hunger, not true.
Hunger is a pressured state of affairs that you haven’t any management over whereas fasting is non-compulsory, you have got full management.
Many additionally consider they can’t or shouldn’t quick as a result of it will ship their physique into “starvation mode” a state of affairs the place the physique begins holding on to fats fairly than burning it off, additionally, not true.
“What they’re speaking about is the place the physique’s metabolism begins to decelerate so considerably that as an alternative of burning 2,000 energy a day, your physique may burn 1,000 energy a day.
In that case, even in case you’re consuming just one,500 energy a day, for instance, you’re going to achieve your weight again. That’s truly what occurs if you scale back your energy. We all know that … as you narrow your calorie consumption, your calorie expenditure goes down as properly.
Hunger mode truly is assured when you simply attempt to minimize your energy. However what’s fascinating is that fasting doesn’t do this. What occurs throughout fasting is that … after 4 days of fasting, the basal metabolic price is truly 10 % greater than once you began.
The physique has not shut down in any respect. Actually, what it’s carried out is it switched gasoline sources. It switched from burning meals to burning [body] fats. As soon as it’s burning [body] fats, it’s like, ‘Hey, there’s loads of these things. Let’s burn our 2,000 energy’…”
This is additionally why fasting tends to improve power opposed to leaving one feeling drained. In case you are obese and torpid, fasting helps unlock all that power already lodged in your physique that you simply beforehand had no entry to.
Fasting forces your physique to begin accessing these shops of power, and as soon as that occurs, your physique out of the blue has a close to limitless provide of power.
Fasting additionally helps enhance different biochemical methods in your physique. There is interaction of hormonal methods just like the mammalian goal of rapamycin (mTOR), AMPK, leptin and IGF-1, all of that are optimized in the best path when fasting. It additionally improves your mitochondrial perform, permitting your mitochondria to regenerate.
So, it is not simply merely turning on an enzyme change to burn fats; it’s a really complicated course of that upregulates within the course of well being.
Variations of Fasting
There are various methods to do an prolonged quick. Following are some variations:
•Water fasting — This is precisely what it seems like: You don’t eat; you solely drink water, for a number of days in a row.
•Water plus non-caloric drinks — A slight variation on the water quick is to embrace different non-caloric drinks, similar to natural tea and occasional sans milk, sugar or different sweetener, together with synthetic non-caloric sweeteners.
•Bone broth variation — One other variation Dr, Fung typically recommends for longer fasts is to permit using bone broth. As well as to wholesome fat, bone broth additionally incorporates a lot of protein, so it’s not likely a real quick.
Nonetheless, in his medical expertise, many who take bone broth as well as to water, tea and occasional expertise good outcomes. “If you’re getting the results you want and it’s making it easier for you to stick to the program, then you should do it,” he says. “If you start getting bad results with fat fasting or bone broth fasting, you can go to classic water-only fast.”
•Fats fasting — Right here, you permit wholesome fat through the quick as well as to water and/or non-caloric drinks. When you in all probability wouldn’t eat a stick of butter, you can have bulletproof espresso (black espresso with butter, coconut oil or MCT oil), for instance. Alternatively, you can add the fats to your tea.
Dietary fats produces a really minor insulin response, and because you’re protecting your insulin ranges low, you’re nonetheless getting a lot of the advantages of fasting regardless that you’re consuming loads of energy. Including wholesome fat comparable to butter, coconut oil, MCT oil and avocado could make the fasting expertise rather a lot simpler. “Lots of people have done very well with this sort of fat fast,” Fung notes, including “Anything that increases your probability of success I’m all for.”
It incorporates beta-lapachone, which upregulates NAD+, an necessary electron switch mechanism and mitochondrial signaling molecule. To that, I add some coconut oil, MCT C8 oil, butter and somewhat stevia. It accommodates about 400 or 500 energy per cup.
A part of the Key is to keep away from protein to inhibit mTOR.
Whereas the extent of protein at which you’ll counteract the advantages of fasting is particular person, Dr. Fung believes you’ll doubtless see outcomes so long as you keep under 10 or 20 grams of protein per day.
As a reminder, protein raises your insulin, though not to the identical diploma as internet carbs do. Extra protein is possible extra damaging metabolically than extra carbs.
“I was looking at some data recently where they graphed where your blood sugars are in relation to where your ketones are. Ketones start to go up as your blood glucose falls [but] that slope changes in different people,” Fung says. “In the event you take a look at, for example, sort 2 diabetics, they’ve a really steep slope. That is their blood glucose — whilst it falls — ketones don’t go up.
That’s in all probability why they really feel like crap, as a result of they’re not getting the ketones. The blood glucose is taking place, which it ought to, however the physique ought to be producing ketones for his or her gasoline for the mind, however it’s not.
In these instances, a number of the fats bombs, a number of the exogenous ketones, may very well make it rather a lot simpler for individuals to get by means of that. As your physique turns into [fat] tailored, which may take two weeks to a month, that shouldn’t occur anymore …
In case you have by no means fasted and also you do a three-day quick, you might really feel fairly awful. We inform individuals to anticipate that. You possibly can both proceed or you’ll be able to take a break and let your physique develop into extra tailored to it.”
The identical applies to starvation pangs, which have a tendency to kick within the hardest on the 2nd day of a quick. By the fifth or sixth day starvation virtually disappears.
Fasting Is Protected, You Can Do It
Barring you fall into any of the Dr. Fung’s contraindicated teams, fasting is protected. Even very sick sufferers have accomplished it and improved their well being within the course of. Dr. Fung has been utilizing water fasting and variations thereof in his medical apply for the previous 5 years.
In that point, he has positioned nicely over 1,000 sufferers on numerous fasting regimens. Some do tremendously properly. One man in his 50’s had struggled with diabetes for 20 years. Inside 2 weeks, he was in a position to give up taking all of his diabetes drugs. His blood sugar was again to regular with out them.
“Then his sister saw he was doing really well. She comes in. She’s on three pills for diabetes. Within a month, we took her off all three. She takes herself off the other two blood pressure medications and cholesterol pills. We took her off six medications in a month and a half. That’s amazing. Obviously, they did very well. But that just goes to show you what can happen when you try some of these things,” Fung says.
“Initially, there was an enormous quantity of skepticism. Everyone thought I used to be loopy. However now I’ve a lot help from my very own native space as a result of everyone has seen the outcomes. I’ve plenty of docs at my hospital who’re doing it. As soon as they see it themselves, they’re like … ‘This is amazing.’ They begin referring me sufferers and say, ‘I want these benefits for my patients.’
As a result of they know they will’t present that type of supportive surroundings that we will present; that we arrange in our clinic, the place we sort of anticipate their issues, give them the help, the web assets, the books … to find a way to do it efficiently.
That’s the important thing: To have the acceptance. There are such a lot of naysayers on the market who say, ‘You shouldn’t do that. You possibly can’t do that.’ However inside my very own native space now, we’re actually seeing a variety of robust help for this, as a result of it’s plain.”

Almost certainly, until you’re taking drugs, you’ll not require knowledgeable healthcare marketing consultant allow you to.
