Fasting

Yes, pick boring time, days to fast. Don't fast on special occasions.

I usually do a partial day fast. I started this routine on accident, due to my work schedule. I'd get up at 8am and get off at 2pm, never really making the time to eat. On most weekdays, my eating hours fall between 2pm-8pm or so. This has worked for me. It makes you feel like you have more calories to eat since you're eating them all in a shorter period of time. Make sure to drink lots of water! I usually eat normally on the weekends, though.

I've been doing various IF protocols for around 5 years now. OP, are you talking about IF or fasting for spiritual reasons?

I almost intermittently fast. I drink a few coffees with splashes of almond milk (30 calories per cup of milk) through the morning. By noon or so, I have a small lunch. Come home from work and have food/dinner till 8:00-9:00pm. It's been fine so far, not awesome but fine, and leaves more calories for later in the day. (I like that part.)

I do IF - works out about 18:6 usually, I never really liked eating breakfast so it works for me in that regard. I also do random 24 hour fasts, maybe 2 in 3 weeks, but just whenever I feel like it.
I've done one 48 hour fast just to see what it was like - I found it really beneficial to decide when I actually felt hunger. As it happened I didn't "feel" hungry until I started think about what to eat when I was finished!
I am not particularly spiritual, but I did make it a time to meditate in a fashion and have a bit of a pamper time for myself. Resetting myself is how I described it to friends.
Not sure it helps massively for weight loss, and you still have to consider what you eat in your non- fasting windows - but it has certainly helped me gain a better relationship with food.

I tried to eat three meals a day but I found that having three meals that were too small to be satisfying just meant that I was thinking about food all day and wanting to snack. I'm now just eating one large satisfying meal every 24 hours. It's early days, but it seems to be working for me. I'm eating the same number of calories but having them all in one sitting means that I can enjoy a big satisfying meal and then forget about food for the rest of the day.

Like others have said, for spiritual reasons or weight loss? I do a full fast for spiritual reasons on Ash Wednesday and Good Friday, and those days for religious reasons, of course. If I were going to do it regularly for weight or health, I wouldn't do a full fast, but an IF protocol. 5:2 or 4:3 are options, but on the low cal days (the 3 or 2), you don't fast entirely. Other IF protocols are about limiting the eating window. I think they work for plenty of people, but you need to experiment with what appeals to/works for your personality. (It's about keeping weekly calories down in a way easier for some people, nothing magical about it. I have a friend who did 5:2 for weight loss (vanity weight) and now maintenance and loves it, though.)

I used to do IF, I would eat breakfast (500 calories or less) and start my fast typically 0900am then skip lunch and dinner and only eat again the next day for breakfast after 0900 so I had a full 24 hours of fast. I did this twice a week, every third day since that worked for my 24/48 work schedule. I saw massive benefits in controlling hunger and not getting off the proverbial wagon. Even if I went crazy for my two normal eating days in between, I always got back on the wagon for my regular fast and then I never wanted to go back to my poor choices after I successfully finished fasting. I found that food tasted way better and was more satisfying to me after a fast. I lost weight easily because I ate maintenance or only slightly under on normal days and only 500 calories on fast days, so my 3,000 calorie weekly deficit was met by the two fasts. I actually lost 1lb a week like clockwork on the IF regimen, more if I restricted furtheron normal eat days. It also helped me to understand hunger and to eat healthier since I didn't want to "go crazy and eat a cheeseburger" after I felt clean and renewed after a fast. As a woman, it never messed with my cycle and I felt fine doing the whole 24 fast. My blood work was great, hair and skin were clear and my undiagnosed IBS went away.

Now saying that I do not do that any more. I'm not against it, I have just found that eating more frequently works better for me now since I am less on the weight loss bandwagon and more into nourishing myself for my training which includes lots of running and now lifting. I like to eat before and after training because I get hungry and hungry burning so much off during higher intensity work outs than I was capable of before when I weighed more and wasn't in shape.

Try IF! You may love it. It it doesn't work or you don't like it, move on to the next thing and see if that fits your life and goals better.
