I used to be a Mormon so from ages 18-25ish I did a dry fast for 24 hours once a month. I tolerated it fine, but I was a lot younger then.
Here I am at age 56 and I am anxious about this. I have a lot of food anxiety from a half century of dieting (my mother put me on my first diet when I was 3yo) and have had many experiences when I restricted food on one day and binged the next.
I have been doing the keto thing for about a month steadily. Even though I’m only 12 hours into this fast, I have hunger pangs (I woke up 4 hours ago and usually would have eaten about 400 calories already) and a headache… but I’ve had a headache for a few days since I almost entirely stopped eating sweetened foods, so it may not be due to the fast yet.
Just looking for a little encouragement and support as I try to make it through to tomorrow morning! Thanks 
It takes some getting used to, and your body is noticing the empty stomach and the small intestine where most of the stuff has moved on. The second half of the first day is tough for a lot of people, but the body does ‘learn’ from it - for most, fasting gets substantially easier with practice. Good luck. 
); started eating once/24h and the weight fell off with the quickness. Eating a ton at one meal worked great for me (this isn’t for everyone, however) and I then was able to go 48h often, and 72h maybe 10 or so times.



I felt really amazing the next day, kind of stoned while I was doing it, but it was a good feeling–very peaceful and meditative. If that’s typical, I get why people do it for religious/spiritual reasons. I lost one pound and now that pound is back, but I’m really trying to work into a routine with keto and fasting so I’m trying not to get discouraged by slow or non-existent weight loss. I decided to do this for my health. Losing weight is necessary for me to feel better and be healthier IMHO but I need to get into a routine with this and I’m still trying to find my way.
Despite fasting three days every week, biking about 45 miles a week (3 days) and lifting weights the other 3 days/week, I hadn’t lost an ounce since my first Sunday weight on May 26th - that I could swear to.
