Do you find that you're able to do cognitively demanding tasks while fasting? Even small fasts seem to sap my concentration and critical thinking. Once I eat again I feel like I think better.

Mental clarity is a challenge when fasting on an otherwise stereotypical American diet... those blood glucose swings are no joke. However I have no problems on keto, or even just a consistently low-GI low-carb diet. If anything, fasting seems to improve my discipline and "depth-first" thinking.

Interesting. I did an "animal-product only" diet for about six months, and I began to feel sorry for everyone else and their inability to think deeply. I was in an almost constant state of enlightenment. Then my buds convinced me to go on a 2000 mile road trip, and after the first stop at Wendy's I lost it, and haven't had the will to go back. It's been like 4 years now.

I have been intermittent fasting for about 23 hours a day in the last decade and this works very well for me, I couldn't imagine to eat more often than that.

However, for the first seven months of 2019 I tried to do 48-72 hour fasts three times every week, but I just couldn't adapt to that. It's nice with the euphoria effect, but in the long run I found it depressing going to sleep without eating and it had a very negative effect on my life quality.

Now I'm back at eating a single meal every day and feel great.

This is just called skipping breakfast. But I guess there was a need for a new fancy term for an old thing.

Except it isn’t. It also involves not eating or snacking after early evening. It is, what it says.

For many people there's no snacking or eating outside regular meals (breakfast, lunch, dinner). In this case 16/8 IF would be skipping breakfast which is exactly my case for many years now.

Old-style 8 hour eating window but slightly shortened. 16 hour non-eating. Simple.

FWIW I used to do the 12 hour thing. Breakfast at 7. Dinner at 7. Lunch in between. Ditched that and went down to 6-8 hour instead. I've found I can actually do 4 hour eating window but that's irritating for reasons other than hunger/satiety.

Once I realized that I was simply addicted to food, and that hunger was simply a withdrawal signal, it made it a lot easier to accept that signal as simply useful information instead of something that was necessarily uncomfortable (to be fair, I consider being cold and other such signals in a similar light). Now I rather enjoy being hungry, knowing there will be a brief hump to traverse before my body replies with a number of favorable responses.

When traveling or over the holidays I realize I'm eating over longer periods I really notice how much less I like it now. I only do it because of basic, maladapted pleasure seeking behavior.

Have you also tried going a whole day without eating, say 8pm as your last meal and then no eating until 2 days later at 8am, basically 36 hours. Doing that once a week or so is pretty effective. There's a whole host of benefits to longer fasts as well. Helps so much with appetite control, resets your hormones, plus autophagy, etc.

Totally this. Of course Anecdata etc etc. I lost almost 40 lbs this year with 5-2 and exercise 3-4 times a week and have been able to maintain my goal weight doing 6-1. I don't eat anything crazy when I am eating. Just less carbs and more protein. I am also vegetarian.

Any tips on scheduling exercise when you are starting out on 5-2?
