I generally do not feel too hungry, especially early in the day, so only ate once per day for years. What a lot of people call a 24h fast I guess?

I felt fine, but BMs got annoying. I now eat twice a day just to keep things moving. And coffee.

I can't say I notice any difference at all in how I feel or weight or anything.

TBH, I don't really consider anything like the above fasting, and have only really fasted I guess once, when I was having a rather bad stomach issue. Day 1 was pain. Day 2 was lethargy. Day 3 felt like some kind of enlightenment. Mentally awake, but I was weak and my brain cloudy. It was a strange feeling of being mentally active but not able to really do anything with it. Maybe my body was giving me faux energy and alertness to go hunt with?

It was interesting, to say the least, but I haven't made a habit of it.

I've been practicing daily 16:8 fasting, and on top of that, I incorporate a weekly 36-hour fast from Sunday evening till Tuesday morning. Over time, it no longer hampers my productivity, but I remember experiencing occasional fatigue and hunger the first weeks when I started. Consistency is key during the initial phase, allowing your body ample time to adapt to the routine. So keep going!

I started exactly the same way, one month ago, but it's still difficult to get through Mondays.

I do 16hrs fasting from 8 pm-12 noon the next day. I keep it after work, starting with an early dinner.

Wow! I do exactly the same thing. Keeps you lean and mean

I do something similar, but I have a late breakfast (like 10:00-ish, second meal is at 16:00 or latest 18:00).

I have tried multi-day fasting several times. Painful to start, but it feels OK in the middle of it, and it feels great after it's finished (works best when immediately followed up by a keto diet, I recommend a vegan keto one, to avoid nasty things). Below 48h of fasting, you don't enter ketosis, so you miss out on many benefits. But never stop drinking water througout any type of fasting.

Yea, I read the same, and what about autophagy? (As I know you can enter it after 26-30hrs fasting)

Vegan keto might be the worst to recommend after fasting, the best / easiest to digest are fats, so a quality broth to break the fast without breaking your digestive tract is what works for me. But I agree that after a multi-day fast keto just comes naturally and easily.

What do you even eat on vegan keto? What’s left when you get rid of animal products and carbs - nuts and plant oils?

I don't know why you are saying this, like there are no plant-based fats?

There exists so many plant oils, olive oil, nut oil, etc. Avocado is also almost only fat.

In meat-keto, you'll eat saturated fats, maybe heated fats, read meat maybe too (bad for CVS), most probably a ton of sodium... no thank you.

Your liver has a ton of glycogen that it has to go through before being depleted and starting ketosis.

It takes between 18h and 24h to deplete the liver, but that is without taking in consideration the contents of the GI tract! There are plenty of carbs and proteins in the GI tract at any time, and that takes around 1 day to digest too.

So I don't know how you managed to shortcut all of that, but I'm extremely interested!

No, but I eat in the evening at 7pm then don't eat/just have water until breakfast at 7am, after I have been to the gym for 60mins.

I have lost 30lb since 01/01/2023. Just cut out junk, reduced portion sizes & only drank alcohol at weekends.
