Last night I finally bought book The Complete Guide to Fasting by Dr. Jason Fung and Jimmy Moore. I’ve been listening to Jimmy Moore’s health podcasts for some time now and he has a new podcast about fasting with his co-author, Dr. Fung.
What most people don’t know about fasting is that fasting isn’t some odd or scary thing. We do it every day when we stop eating in the evening, go to bed, and don’t eat again until morning. One form of fasting recommended in the book is the 16 hour fast, when you stop eating at dinner and don’t eat again until the next day at noon. Since human beings feel the least amount of hunger during the morning, the 16 hour fast is something many of us have done without knowing we are fasting!
I’ve actually been doing 16 hour fasts for years without thinking of it as fasting, ever since I read a health-related book which recommended skipping breakfast. In our snack-happy culture, we all need to start putting some limits on how many hours a day we are eating. (In 1970 the average person ate— meals and snacks— three times a day. Now we eat 6-7 times a day— and the diabetes and obesity rates are sky high.)
One thing that interests me about the book is that one author, Dr. Jason Fung, is a nephrologist (kidney doctor) who works with many diabetic patients. I have diabetes and kidney disease myself, and have endured a series of second-rate nephrologists who seem oriented to watching my kidneys deteriorate until I’m condemned to their dialysis clinic.
Dr. Fung seems to be giving his patients hope that their diabetes and kidney disease will get better when they follow his treatment which includes ketogenic diet and fasting. One of my nephrologists, by contrast, told me kidney disease never improves (even though mine had) and is never affected by diet changes.
Dr. Fung recommend his patients go on 3 fasts of 36 hours per week. How that works is:
Day one: stop eating after dinner
Day two: eat nothing all day, water and plain coffee and tea are allowed.
Day three: don’t eat until noon/lunch, stop eating after dinner
Day four: eat nothing all day
Day five: Don’t eat until noon/lunch, stop eating after dinner
Day six: eat nothing all day
Day seven: Don’t eat until noon/lunch.
You will notice that since day seven is followed by the next week’s day one, and so there are two eating days in a row.
DISCLAIMER: Nothing in this blog is to be construed as medical advise, and you should READ THE BOOK and pay attention to its restrictions and advice— including the advice to NOT FAST if you have certain medical conditions and CONSULT YOUR DOCTOR about your fasting.
I’m currently on Day Two of the plan about and have not eaten since 6 pm last night. It is currently nearly 1 pm and so I’ve gone 17 hours— which I’m fairly used to. Things will get tougher in a few hours, and so I have to keep drinking my water/tea regularly to prevent excessive hunger.
My writing has been adversely affected by my health problems in part because I do keep going off my ketogenic diet, and find it hard to get back on because going OFF saps my energy. Fasting, like going keto, tends to increase your energy.
I’m also hoping that the alternate-day fasting will give me extra time both for writing and for getting things done around the house, because I won’t have to be spending as much time cooking and washing dishes. I will post updates on this blog to let you know how it’s working out.
