Tagging to follow. I'm interested in what Dr. Jason Fung and others have to say, so I'm also interested in this discussion.

Many years ago, before LCHF, I used to do IF accidentally - before I knew it was a thing. I used to often skip breakfast and on those days I wouldn't get hungry till early/mid afternoon. On the days I ate breakfast I would always be hungry by late morning. On the IF days I felt great. Now I understand why.
So lately, I have been experimenting with it in combination with LCHF - cautiously - because I don't want to put any additional stress on my body (and mind, LOL - I am sure I have had excess cortisol issues over the last 5 years or so).
I exercise between 6am and 7am three days a week and I have never eaten before that session. So now, I am stretching the fasting out until 12 noon, whenever I can. Some mornings I can't. I have had to get over the notion that you need to eat protein with 2 hours of heavy exercise, which you hear so often. I now understand that the muscle rebuilding and maintenance happens at night one to two nights after the exercise session - by which time I will have protein in my system.
On these days I am feeling good. I think the early morning exercise has a hunger dampening effect which helps. I don't do a 100% fast on those mornings though. I do have a coffee (black when I can) afterwards with the gang and I have just discovered the joys of Keto Boullion -because the one problem I was having on these days was feeling c*** - and I now understand it was lack of electrolytes.
If you want to learn more, have a look at Abel James' Primal blog and Mark Sisson's Daily Apple blog. Primal seems to be a LCHF version of Paleo and they both (I think) advocate IF and have well researched info to back it up.
I'd be interested in the experience of others.

I do. But since I have been away on holidays, I haven't got back to it. I skip breakfast and have a late lunch between 1-3pm depending upon how hungry I am. I was doing this twice a week.

There is a group on MFP which is dedicated to IF and low carb. They have just started the group.

I got interested because of Dr Jason Fong's videos.

Thanks @dasher602014

I do, but nothing consistantly. I tend to skip breakfast but I add coconut oil to my coffee - not sure if that can still be called fasting or not. Every few weeks I skip a day of eating. Nothing forced. If it is not a hungry day, I just don't eat.

IF is my regular eating pattern. I typically eat one meal per day at supper, so I guess I do 23:1, with longer fasts from time to time. I do it for increased energy, mental clarity and elevated mood, along with boosting weight loss benefits.

When I first went Keto, I was using cream in my coffee with artificial sweetener, which kinda made the fasting null...

Just curious - did you discover this via experimentation or education?

I've been doing it for about 3 months now. I eat between 1pm and 9pm only. I'm never hungry and actually find it quite easy. I also train fasted. Weights 5 days a week and one session of HIIT on a treadmill. Weight is coming off, fat is coming off and I'm actually starting to gain some definition.

I've been doing 18 hour fasts almost every day for 3 weeks, and that suits me very well. I drink coffee and bone broth as I fast.

I am slowly working myself down to a straight 16:8. Currently I have h&h and CO in my coffee. I hope to work down to CO and butter, and then maybe nix the stevia. But honestly, I'm unsure I can manage without the squirt of liquid stevia.
