I do daily-shortened-feeding-window style of IF, 16:8 ... 1p-9p is my window, and usually it starts later than that, sometimes it goes later too. I'll throw in a 24h fast now and then.

My version of fast is 'fasted state = no calories', so I'm okay with black coffee, diet sodas, etc.

I have coffee with a little half and half and coconut oil in the morning (~100 calories total) but don't eat food until 1:30-2:00. I'm done eating by 8 usually. I'm not strict about my eating window, but having 2 meals works best for me with keeping calories down.

I work out in the morning and while I'm fine to do it fasted, I have to do it caffeinated (45 minute drive to gym + 5 am gym start time), so I count my coffee as my preworkout. As the weather warms up I'd like to switch to iced coffee or tea which I'm fine to do without cream, so I may start a more authentic IF. It will be interesting to see the effect.

I've been fasting for a long time now....can't really remember when I started. I usually follow at 16:8 IF schedule. Breaking my fast around noonish and wrapping up eating around 7pmish. I consume no calories (black coffee is ok) during my fasting windows.

I throw in a 24 hour fast about once a week. I travel a lot for work and that fast usually happens after I've had a day with higher calories or carbs than usual.

Exercise while fasting hasn't been an issue as long as I'm well salted. Lol. Im partial to trail running and some of my best runs have been while fasting honestly.

I go from around 6pm until around 11am. I find it easy and natural. I always drink my coffee black no sugar so I don't have a problem. Jason Fung, of IF fame, says you can have a teaspoon or two of milk or coconut oil in your coffee if you must. He also allows bone broth because it doesn't spike insulin.

Hi,
I do 18/6. ( I usually eat my first meal at noon.. second by 6) ... my body seems to love it... sometimes I have a morning treat of coffee with stevia and a splash of unsweetened almond milk and of course water
Good luck!

I've been doing 18:6 with my eating window at noon to 6pm. When fasting I have nothing but flavored water (like La Croix) and unsweet green tea. No artificial sweeteners of any kind, as Dr. Fung says they can cause an insulin response. I break my fast with a LCHF lunch.

The salt is definitely ok, but the sweetness in the mio may spike your blood sugar. Anything sweet can do it in some people. The only way to know for sure is to test your blood glucose. IF is sooo easy. Like Dr. Fung says you just don't eat. Watch this https://www.youtube.com/watch?v=VIhhrYjVhOk

Interesting video clip @flitabout38. Thanks.

Well, I did a fast of 6 days last month. No food just water. I was already keto adapted so I think for me it was easier because of it. But still, I don't think I will do it again. { I want to add that I am on no medications, and have no major medical issues. My daily work is farming so I exercise a lot. I would NOT recommend this for people who are ill or who are unable to walk a flat mile without losing their breath in 60 degree temperatures.}

But it was an interesting experience. I stopped feeling hungry unless I saw food. I was cold all the time. I was very much into ketosis cause my pee sticks were very dark. Everything seemed to go slower including me. I had to drink broth every day (while on low carb I only drink it every 2 or 3 days) to keep from being dehydrated even though I was drinking gallons of water.

That's one thing I feel Dr. Fung, and most fasting gurus, do NOT emphasize enough about straight water fasting. You have to watch your electrolytes and plain water ain't going to do that. You can see some people who record their fasting on VLOGS as they slowly become more and more dehydrated and suffer all the pain that comes with that. I scream at my screen, drink some broth or bullion or even ..gag..gator aide.

Anyway, I did lose a pound a day but it all came back when I went back on my low carb diet. But I have noticed those six pounds have again slipped away during these last 3 weeks. My hair which was gray has gotten more brown and my pierced ears have been trying to heal up. I also found that I had no arthritis pain after day 3. And if I stay away from artificial sweeteners, I have no arthritis pain now at all. The lose skin on my neck seemed to have tighten up some and though weight loss was nothing to write home about, my belly is now much smaller. But even 3 days after I ended my fast, I felt like I had run a marathon. My body felt exhausted and worn out. Now 3 weeks later I feel fine and energetic.

Anyway, I'm going to try fasting 2 days a week once a week now that all my easter guests have gone. I think intermittent fasting will be easier for me.

I am working up to doing a week. My daughter is sort of going to do it with me. I am going to water fast and she is going vegan. So far I am up to 24 hrs pretty sad right? It's so hard with 5 kids and husband who are hungry all the time!!!

I have similar IF. No coconut oil just half and half. Really strict on my calorie count, workout routine, Mac portions but need more accountability reducing my 6 window. I break with late lunch ~2pm with protein shake and bar after workout.

I started my first 24 hour water fast, and so far just a headache, so I think I need some salt. I'm trying to work my way up to regular ADF, but that's definitely down the road.

I've started a new job and having trouble figuring out my meals, etc., so I'm just trying to wait as long as I can to eat so I don't do a specific time frame and just eating mostly cheese with maybe some crackers (I know) and egg salad. Working close with someone makes me fear the breath and pretty much intense smell the keto foods I like have. Oops, more than you asked.
