"Instant" reversal with fasting?

Here's a fascinating e-mail we received recently. It came from a man in Hawaii who dropped his heart scan score a modest amount, but did it in two months using fasting. He also has the advantage of access to the Holistica Hawaii scan center with our friend, Dr. Roger White. His experience is so fascinating that we asked for his permission to reprint his story which he did enthusiastically.

So here is Don's story:

I am a 61 year old male with a history of heart disease in my family. My maternal grandfather, for instance, died at age 39 of a
heart attack and my mother died of a stroke. There are other instances in my family as well.

I, personally, before going to Holistica had had three heart procedures; one radio catheter ablation for WPW Syndrome, and two radio catheter ablations for atrial fibrilations. After suffering with WPW for over 30 years and A-Fibs for about a year, those issues seem to be behind me fortunately.

Three or four months back, however, I was suffering from shortness of breath and slight chest pains when doing the uphill part of a 5 mile walk that I do almost every day. My wife had had a coronary heart scan several years back at Holistica so that's how I knew about it.

I had a scan done on October 4th this year. The scan did show fairly
advanced plaque build up; my total coronary plague burden was
312.9. The day following the scan I felt absolutely terrible; lightheaded, weak, much like feeling you were at death's door.

I had read a book a number of years back about therapeutic fasting
(water only) called "Fasting and Eating for Health" by Dr. Joel

According to his book, one on the areas where he consistently has dramatic and quick results with fasting is with reducing arterial plaque. Based on how badly I was feeling at the time, I decided to start an immediate fast. Within just the first 24 hours, the relief was dramatic and amazing. I continued the water only fast for 3 weeks.

Yesterday, December 1st I went in for another cardio scan instead of the coronary angiogram that I had previously been scheduled for. I could tell they were a little confused why I was doing that but went ahead and did another coronary EBT scan.

When I went in for the doctor consultation, Dr. McGriff said, "OK, exactly what is it you've done since last time." In less than two months, my coronary plaque burden had dropped to 296.2. That's a 6% reduction in less than 2 months. Had I gone back in for the second scan right after my 3 week fast then it probably would have a 6%
reduction in less than a month.

Frankly, based on how good I've been feeling (I'm even thinking of
getting back into jogging instead of walking), I was surprised it was
only 6%. Based on the common experience, however, that it sometimes
takes a year or two to just stabilize your plaque increase, much less
actually start losing it, the doctor was truly startled and
surprised. He said he had never seen such a sudden reduction as that

We are still going to proceed with the coronary angiogram and I
intend to apply what I find in your book but I thought you might be interested in these results since I've never heard or read of anyone actually measuring the effectiveness of a fast with before and after EBT Scans.

I admire your direction and work focusing on prevention instead of catastrophic management like most doctors. Dr. Fuhrman is very much the same with the greatest attention on prevention so if you haven't heard of his book you might be interested. Especially interesting regarding this particular issue is Chapter 5 entitled, "The Road Back to a Healthy Heart-the Natural Way."

I can personally verify everything he has said about the fasting procedure itself from start to finish. I consider his book the Bible about fasting. As I mentioned, given your similar direction in medicine, I thought I would bring my personal experience on the matter to your attention for your consideration. Maybe in a future edition of your book, you might want to include some information on fasting.

Anyhow, I hope you will find this helpful. Any other questions,
don't hesitate to e-mail back. Please keep up your good work and
thanks for what your doing!

Yours truly,

Don P.
Honolulu, Hawaii

Isn't that great?

Now, in all honesty, a change of 6% could conceivably be within the margin of error for heart scanning. (Although several studies from a number of years ago suggested that variation in heart scan scoring was about 10%, sometimes more, in my experience, on EBT devices like the one Don used, variation is <5% at this score range.) Genuine regression would probably be better documented by yet another scan down the road. If the trend is consistent, then it is probably real.

Nonetheless, Don's story may support we've been saying for some time: Fasting is a rapid method to gain control over plaque--but I didn't know it might be that quick! Perhaps Don is a living example of what I've called "instant" heart disease reversal.

Don is potentially off to a good start. But, unless he can periodically repeat his fast, he will still have to engage in a program that allows continuing control over coronary plaque in between fasts. Also, fasting cannot address issues like vitamin D deficiency, lipoprotein(a), and any residual lipid/lipoprotein issues. But I am continually impressed with the power of fasting to "jump start" a program of heart disease reversal.

It would be a fascinating study to perform, with serial heart scans within brief periods of weeks or months to gauge rapid response. However, we need to keep in mind that as wonderful as heart scans are, they do involve modest radiation exposure.

It might be interesting in future to add a fasting "arm" to the virtual clinical trial. That might yield some great insights.

    Re: "It might be interesting in future to add a fasting "arm" to the virtual clinical trial. That might yield some great insights."

    Yes I am sure it might. Let me think, fasting = burning one's body fat (and a little bit of  muscles) = ketogenic metabolism.

    Hmm, what is that other method of inducing a ketogenic metabolism?

    hmm.so if a diabetic did this after so many hrs if bg fell low wouldn't you liver start spewin some glycogen, then bg would rise,making you hungry, but only water,man would you lose weight, would this be ok for a diabetic, ????
    GoodonyaDon, did the hunger bother you or did it stop after few days???

    How long a fast do you feel is necessary to be beneficial?  

    Do you think the whole intermittent fasting thing (fasting 24 hours on /24 hours off) is useful?  How about just a one-day a week fast?

    How long would a fast need to be to get results? It's rare I can go even eight waking hours without getting the shakes (I've been this way since my teens).

    Interesting thought.

    But I do think that fasting provides a unique phenomenon, unlike that of a low-carbohydrate, ketogenic diet. I can only speculate why. But the physical and emotional perceptions  experienced during fasting are a world apart from low-carb eating.

    Nobody knows. You will find discussions about length of fast and various patterns of fasting to achieve weight loss, regression of various disease states, but no real data on regression of coronary plaque by heart scans. The Track Your Plaque experience is informal and has not been subjected to formal examination. But it sure is fascinating, particularly when you hear about experiences like Don's and the stories articulated by Dr. Fuhrman. (I'm going to ask Dr. Fuhrman for an interview for Track Your Plaque.)

    This is a very common phenomenon in the carbohydrate/wheat addicted. (I assume you are not diabetic.)

    I know of no way to get beyond it except to get beyond it. Also, you will need to work with your doctor if you are taking medications, particularly blood pressure meds, etc.

    I read in the TYP report of optionally discontinuing supplements during a fast, what about my statin?

    What is the best approach to supplements during a fast?

    Keep taking all supplements including TYP program supplements?  or not?

    Dr. Davis

    I am possibly in the beginning stages of diabetes: FBS good, but a1c a bit high. I had been drinking a lot of koolaid (with sugar), and doing a lot of processed grains, and also starches when the a1c test was taken.

    I haven't gone into my new GP with the a1c results yet (my ob/gyn caught the a1c), since I have a colonoscopy scheduled next week. I'll go to the GP after I receive my colonoscopy results to see what they want to do about the a1c.

    Instead of koolaid, I now drink tea with 1 tsp of sugar in 2 quarts, the rest sweetened by stevia. I eat about 3 pieces of bread a week now, and no potatoes, rice either. I've been using cellophane/glass noodles instead of regular pasta.

    So we'll see if those changes made enough of a difference to bring the a1c down.

    Back to fasting: I wonder if reducing high glycemic carbs, especially wheat, will eventually enable me to fast longer periods? I should start a food/carb journal, makring what/how much I ate, and how long I can go before the shakes set in.

    Though clearly an improvement, the amount of carbohydrate intake you are describing would make me either very hyperglycemic (high blood sugar) or diabetic.

    I find completely divorcing yourself from these sugars and sugar equivalents easier than cutting back, since continued inclusion of sugars and wheats maintain a craving.

    anonymous, it sounds like you have reactive hypoglycemia.  This means you have a slow phase 1 insulin response, so when you eat, your bg goes really high, then your pancreas overreacts and splurts out too much insulin and you go low.  Most people with reactive hypoglycemia progress to diabetes if they don't get it under control because it's a disorder of insulin production.

    You really need to get a bg meter and begin testing how specific foods effect you.  You can't rely on the glycemic index, because we're all different - the GI is an average.  The diet you described *may* be fine for you; it would massively spike my bg though.  You have to find out what really works for *you* and the only way to do that is to test.

    There's good advice about testing at these links:


    Meters are often given away by the companies for free, or free if you buy 100 strips or such.  The biggest cost is in strips, so you want a meter with cheap strips unless you can get a doctor to prescribe it and insurance to cover it.  Both Walmart and Walgreens have cheap generic meters with inexpensive strips.

    If the bg targets at the links I provided make you feel hypo, it's cause you've gotten used to high bg feeling normal.  Just aim at higher targets for a few weeks while you adjust before going lower.  

    I hope you follow this advice and find out what you need to do to avoid diabetes; I'm a member of the club and we don't want new members!    ;)

    Good luck.

    Thanks Dr. Davis and jpatti,

    Now that my procedure is out of the way, I'm cutting all sugar, bread/grains, and starches, and have started a food journal at http://www.myfitnesspal.com and I'm going to leave the times the meals were eaten in the food notes so I can monitor how I can go before the shakes/light-headedness sets in.

    As soon as my procedure results come back, I'll make an appointment with my new GP to see what they want to do about my a1c being 6.3 five weeks ago. Maybe they'll retest, or start me with a glucose monitor. If it's the glucose monitor, then I'll be able to do the PP tests to see which foods do me in on my blood sugars. But if I have to test, maybe they'll be better numbers with my stopping sugars, grains, and starches.

    STAN,in Canada an A1C over 6.1 is considered diabetic, may want to have a 2 hr GTT as well for firmer diagnosis as some docs don't treat it aggressively and it does damages minutely everytime your bg is over 140, from what I have read. I'd buy my own meter and work aggressively to stop it in your tracks as it contributes greatly to calcium score as well. If I could do it all over again and had a mentor that knew what I know now I may be healthier and as patti says this isnt a fun club.... you shouldn't even peek into the doorway of, so jump start it now .You may find it helpful to read Dr Bernstein's Diabetic Soltuion, new editon Oct 2007.Its very similar program to TYP except for few diff to keep bg low. Of course he is not the guru of calcium score etc so the 2 work well together, goodonya for paying attention to it SmileGood Luck.

    S's progress in stretching out hypoglycemic events by cutting out quick carbs:

    Although I haven't cut out quick carbs 100% in these last few weeks (small burger at drive through once, with a frozen hotpocket later that day -- I was run down and wasn't up to cooking, and used flavored creamer in coffee twice), I've been able to go 9 hours before feeling the beginning stages of hypoglycemia today:

    0530 Woke up
    1000 Kefir (whole milk) w/ wheat germ*
    1730 Baked chicken thigh, beans, greens, 1/2 tomato, 1/2 cucumber, 1 tbsp ranch

    *I've been using wheat germ in my kefir to increase fiber. Since cutting out most wheat products, except my puny day, my gastro problems haven't bothered me. But the day after I ate that burger and hotpocket, my gastro problems returned for most of the next day.

    I don't have other signs of gluten allergies, but I wonder if I might be sensitive to gluten or wheat. I'll bring it up to my gastro dr when I go in for my follow up. I already know there's no CA or polyps, and from my pics there doesn't seem to be any diverticulits pockets, or raw Crohns area, but I am not a gastro, and I'm basing that guess on only a few pics.

    But between battling against hypoglycemia and probable beginning diabetes, and also gastric problems, I am definitely stopping wheat (and also continuing with the slow-carbs only). I still have to make an appt with my new GP regarding my a1c of 6.3 a few months ago when I was a glutton with sugar, wheat and other starches.

    I don't know how much weight I've lost since I don't have a working scale yet, but my face has thinned and almost no double chin (now it's only noticeable when my face is towards my neck), and my waist has started to indent again.

    I'll check back in when I've found out if my dietary changes helped my a1c, or when I can fast all day.

    Have you tried ground flaxseed in place of wheat germ?
