Another Fasting Experiment with ADF - JUDDD - EOD - QOD

- POSTED ON: Apr 10, 2016

Here is a picture showing my current diet experiment.  I’m using my own Alternate Day Fasting (ADF) eating plan which is based on Dr. Johnson’s Up Day Down Day Diet (JUDDD); and Dr. Varady’s  Every Other Day (EOD) diet; and Dr. Daugirdas’ QOD diet.

Dr. Fung’s blog, (see DietHobby’s RESOURCES, Links for a link to his blog, Intensive Dietary Management) inspired me to do additional experimentation with Intermittent Fasting.

Previously, I’ve written several articles about Intermittent Fasting diet plans here at DietHobby.  You can do a search of DietHobby for them, or you can go to DietHobby’s BLOG CATEGORIES, Fasting to find them. (Look near the middle of the right hand side of this DietHobby page to find the heading: Blog Categories.)

Much of the fasting research that is quoted by Dr. Fung in his blog and new book, The Obesity Code is from Dr. Varady’s research and experimentation of her Every Other Day diet.

The plan alternates “fasting” days with “eating” days.  Dr. Johnson refers to “fasting” days as “Down” days, and “eating” days as “Up” days.  Dr. Varady refers to “fasting” days as “Fast” days, and “eating” days sometimes as “Fed” days and sometimes as “Feast” days.  Dr, Daygurdas refers to the fasting - eating days as “On” and “Off” days.

During UP or FEAST days, total calories are to be a “normal” amount … ideally they will be no more than 10% above an individual’s Total Daily Energy Expenditure (TDEE). 

During DOWN or FAST days, total calories are to be only about 25% of  an individual’s Total Daily Energy Expenditure (TDEE).

For the mythical average woman whose TDEE is 2,000 calories, an UP day would be from 2,000 (up to 2,200) calories; and a DOWN day would be no higher than 500 calories.  Alternating Up days with Down days results in a 2 week pattern of rotation making a 14 day period in which the average calorie intake would be 1250 calories daily ….then repeat, indefinitely.

My UP days are based on my own personal Total Daily Energy Expenditure (TDEE) which is close to 1,000 calories.  Adding 10% brings it up to a total of about 1,100.  My plan calls for 3 weekly UP days.

My DOWN days of about 300 calories are close to ¼ (25%) of my TDEE.  My plan calls for 3 weekly DOWN days.

1,100 plus 300 equals 1,400 divided by 2 equals 700 calories… Therefore a 2 week rotation of this pattern would result in a total Average calorie intake of 700 calories daily.

Each week I am including one MEDIUM day of about 700 calories in order to keep every week’s rotation of individual Up & Down days consistent.

My ADF Plan includes two alternatives to my “Basic” plan.  Alternative 1 has 2 consecutive UP days on Saturday & Sunday, and Alternative 2 is has 2 consecutive UP days on Friday and Saturday.  See picture above for details.

I am 71 years old, 5'0" tall, and an inactive, reduced obese female (high weight 271 lbs) who has been maintaining a normal BMI for 10+ years, and my individual TDEE of about 1,000 is low, but not “abnormally” low.

For ME, an average daily intake of 700 calories should create a daily deficit of about 300 calories, and … according to the 3,500 calorie rule… result in a weight-loss of about ½ pound per week.


To bring my calorie counts into proper perspective... note that the well-known and often-used  Mifflin formula gives an "AVERAGE" person of my age, size, and activity level, a (RMR) TDEE of 1150 calories, and a BMR of 985.  I've been keeping computer records of my calorie intake & weight every day now for about 12 years, and so I know that my own TDEE is about 100 calories or so below the "AVERAGE".  Women who are younger, taller, heavier, and more active often have very little understanding or knowledge of how low the TDEE is for a short, light, inactive elderly woman... and of course, it is even less for a "reduced obese" one. 

For those people who think my TDEE calculation is too low.... HERE's a little personal lesson. Follow this link to an online calculator that uses Mifflin to determine both BMR & RMR (TDEE).  If you are a female use it to run your own numbers. After you've done that .... try changing your own age to 71, and moving yourself to "Inactive"... Look at your numbers change.  Now, change your height to 5'0".... Quite a difference, right?...  Now give yourself an elderly, short, inactive person... a BMI of around 22.5 (which is somewhere near the middle of a "normal"  BMI)  by setting your weight at 115 pounds.... Now, look at the resulting numbers.... which should be around 985 BMR, and 1150 RMR or TDEE.

I'm intrigued by alternate/intermittent fasting after watching a couple of the videos you have posted here :) it's something I think could be very useful during times of slowed weight loss .. a plateau etc; unfortunately I have recently discovered that I am not absorbing enough of my medication because I'm not taking it with fat so now I have to determine how to accommodate twice daily "meals" in a fast :O I'm now thinking about a 19-hr fast :) also, I think it is inspirational how meticulous you are about record keeping and I'm very impressed that you have done so for the last 12+ years :) yay you!!

I missed whether your weight is higher than you want and that's why you're playing with fasting. Or looking for a way to eat a bit more on some days? Feel free to refer me, if you don't want to repeat yourself.

             Hi oolala, I'm playing with fasting as a part of my (dieting hobby) i.e. my ongoing efforts to get and keep my weight in my "normal" BMI range. During this past 10+ years, I've found that it takes ongoing, continual, sustained efforts to avoid regaining my lost weight, and that my body RAPIDLY adapts to every way-of-eating in its efforts at Regain. I see that you found my "End of the Line" post which explains the dilemma I've found myself in during the past several years. At this Point as of TODAY, since January, I've managed to drop my weight to the low-mid 120s which puts me just inside my "normal" BMI range... I go into "overweight" range above 127 lbs. No matter what eating method I use, I find it impossible to keep my calorie intake at the extreme low level .... every day... that it takes to keep me from weight regain, therefore my normal practice is to intersperse very-low-calorie days ... like 500 calories and under ... with higher calorie days such as between 1000 and 1300. Even working toward an AVERAGE of the number my body will tolerate without weight-regain, is not an easy task for me.... and So it goes....

Haven't been keeping up enough to know if you've found this is workable or effective or not. I've been experimenting for the last year. For now, I've hit on some good results in that it feels more comfortable to have "down" days, which I like to call, as Varady says they are officially, modified fast days. There is a great deal of luck in this, as this style actually dovetails my appetite more these days. I think I must have had some kind of adjustment go on because I now often feel very good the day after a MFD and have my first meal especially. It isn't as if the MFD is carefree yet, but being able to look forward to that rise in well-being is a boon. I wasn't doing it to lose weight, but it seems to be stabilizing a little lower. However, I've lost muscle this year. Have to work on my thinking on that. I admit totally that I"m just in denial. Or maybe when you admit it's denial and you just keep doing it, it's called something else...

             Hi Oolala, Yesterday, I posted a totally LONG reply here to your comment, but my website tech was in the process of changing Servers, and the entire post was lost. SO..... if you read it already before it disappeared, Good, but if not, it's lost. For recent weight and diet info on ME, personally, go to BLOG CATEGORIES - Status Update where you'll find charts & Graphs and articles. I'd love to hear more from you about how you're doing.
