My sleep hasn’t suffered due following this cycle, maybe for other reasons so far, but not due to this eating pattern.
Today I’ve been pretty hungry, which thwarted my plans to make this a rather low cal day. But the intake will still be lunch less than yesterday and according to my fitness tracker yesterday gave me a burn of about 4100. I wonder if that has anything to do with it. I didn’t workout today, it is a recovery day, so the calorie burn is much lower than it was this time yesterday.
Aaaaand just like that I’m full…
crazy keto LOL. I was all set to be greedy and had all the food setup ready to eat and be merry (and there were chicken gizzards too!). And after a few bites it was apparent that I was done. Hahahahaha! I still finished off the eggs and bacon though, everything else will be here for tomorrow.
Those look like good results to me. I notice you so some water only fast days and some where you have coffee with cream. I use coconut oil in my coffee and bone broth along with lots of water when I fast, I don’t mix it up. Over 8 days I lost 6.6 lbs. Fasted 2 days, feasted 2, fasted 3, feasted 1, I am still in feasting mode today, after tomorrow I want to do another 2 day fast using avocados and water only to see how that goes.
I also take supplements, fish oil, mag.,potassium, CoQ10 d3, and turmeric and if I feel flu like symptoms I will add salt and ACV to the broth as well. Only had to do that once.
No one I know personally eats this way nor are they into fasting, thank goodness for the forum 
Ended a 90 hour fast a few minutes ago. Began fast at 221, ended at 213. If I can keep the bounceback to 2 pounds like last cycle, and wind up at 215, I’ll be ecstatic.
In 28 days of Feast/Fast cycling, I have dropped from 234 to 213. This stuff might just work, maybe!
I sleep less when I fast, for sure. Trouble getting to sleep. But I’m not tired either.
Hi all. I’m new here, but I have done keto on and off for about 8 years. I lost over 100 pounds and have kept it off.
The last couple of years my weight has fluctuated and had started to creep back up. It also seemed like keto wasn’t working for me anymore. I never registered any on the urine strips and I was rarely even registering more that 0.3 mmol/ml in blood tests no matter how low carb and protein I ate. It seemed like I had broken my metabolism and I blamed eating very low carb for screwing up my gut microbes.
A few weeks ago a friend was doing a two day fast and I decided to give it a try too. The longest I had previously done was about a 24 hour fast. I did about a 55 hour fast supplemented with MCT oil and HWC and my blood ketones were the highest I had seen in a very long time. I lost about 10 pounds.
Since then I have done a few more fasts of around 48 hours and it’s been pretty easy and I’ve started losing fat again.
I just started a fast about 24 hours ago and I’m going to see how long I can extend it. I’d like to do 3 or 4 days.
I don’t generally track calories or macros, just trying to keep an eye on how many net carbs I eat.
I’ve enjoyed reading this thread and I’ve learned a bunch about extended fasts. I’m looking forward to learning more.
Congratulations on your success, that is BIG!
As far as having fats during a fast I have found that my blood ketones are marginally higher when I do consume no more than 500 calories of fat on a fasting day. I say marginally because I did the tests during a 46-day fast and I did 3 days using HWC (about 1/2 cup total) and then 3 days of water only. My blood ketones averaged 5.1 on days with fat and 4.9 on the water only days.
Your supplements sound good especially if they work for you! I put a bit of emphasis on salt as it manages the storage and processing of many electrolytes and nutrients. The more I learn about salt the more I believe that we need between 3500 and 5000 mg of sodium (1.5 to 2.5 teaspoons of salt) per day. There are many studies showing the recommended amount of 2300 mg or less actually increases the risk of many ailments.
Hi Ron, thanks for posting your stats & experiences in such detail, it’s very interesting. How do you view the 3.4 lbs gain from the feast day on Thursday 4/27 - when that is factored in the weight lost is 6.2 lbs which is still a significant result in that time period. Is the pre fast weight gain from feasting the price of admission that is paid to hop on the feast/fast weight loss ride (dare I say rollercoaster - goes up before it goes down at great speed) ? One step backward in order to take 3 steps forward? Just trying to get my head around it. Very curious to see what happens as you continue the cycle, a graphic of this would be awesome.
@Adam: as a bit more background: I had done a 46-day fast for Lent and then almost 2 weeks of feasting immediately before beginning the fast/feast cycling. The Friday that I gained the 3.4 pounds was my first fasting day, after my 12 days of feasting ended and I ate almost 4000 kCals the Thursday before.
Here is a 30-day graph of my weight so you can see the end of the fast; then the feasting with some weight gain; and then the fast/feast cycling.
I used the my body weight including the 3.4 pound gain as the starting point for my weight loss from the fast/feast cycling.
Perhaps not quite what you’re looking for, but @Fiorella provided this:
A general point: if you fast, some weight regain when you start eating again is inevitable. Why? Because one contributor to your overall weight is the contents of your digestive tract, from the mouthful you just swallowed, to the stuff that’s getting ready to come out the other end. If you stop putting stuff in, but stuff continues to leave your digestive tract (not just as poop, but by being absorbed into your bloodstream so it can be metabolised, and then excreted as urine or carbon dioxide), then inevitably you will lose some weight that WILL come back when you eat again.
Jason Fung, the god of all things fasting, says that a good rule of thumb is that you will lose around half a pound of fat per day while fasting. That would be full fasting, i.e. non-caloric liquids only.
I hate to post this on 2 different threads but it applies to this topic as well.
This graph shows my eating and weight changes for the last few weeks as I ended my long fast on Easter, April 16, and then started 12 days of feasting. Then I went onto fast/feast cycling on April 28.
I fasted from 7 PM Thursday, April 27, until 5 PM, Sunday, April 30 (70 hours).
I feasted until 7 PM, Tuesday, May 2, (50 hours)
Am fasting again since 7 PM, Tuesday, May 2, and have lost 12.4 lbs. in about a week!
I like this cycling so far!
I’ll be doing a fat feast tomorrow - I’m totally looking forward to it. At least it seems like it’ll be a feast in my head right now. LOL there will be bacon fat, heavy cream, a few strawberries (with the hwc), maybe an egg or two, raw cacao butter, butter, coconut milk, and coffee… and coconut oil, and some cheese; I’m out of macadamia nuts, though. Doesn’t it sound like a feast? I haven’t put it all together in my head, but I’m gonna do it!
At about 42 hours of fasting now. My mouth is bored, but my stomach is not at all interested in food yet. I’m thinking that 72 hours sounds good, but we’ll see how it goes.
I love this thread, gives me the motivation to push my fasting cycling to see where I can go!
Ron, did you mean to type “feasting” for the 12 days? lol, I’m a proofreader by trade… 
Starting another fat-supplemented fast this morning (well, last night, technically). Managed to keep off 3 of the 5.5 lbs I lost on the previous fast, so if that pattern continues, the feast/fast cycle should be a very effective tool for breaking plateaus.
Thanks!
Yes, I live with a part-time proofreader as well, I keep her very busy!
Charmaine, Have you done these kinds of feasts before. What is the goal? I’m always interested in the self-experiments we take on. Sad you have no macadamias. They’re my favorite.
