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 ne…

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…

"withdrawal signal" is a very precise way to phrase it

I’d like to fast until lunch time but I haven’t found any substitute for milk in coffee and I fear that breaks any fasting benefits.

Try butter in your coffee. You get the creaminess without the lactose sugars.

It also helps to have really high-quality espresso-style (extracted for <30 seconds) coffee when trying to ditch milk. You can also transition witu honey.

Same problem here. I'm also confused because some sources say coffee (black) is OK during fasting, but I've also heard that even black coffee "wakes up" the metabolism enough to lose the benefits. Could someone who knows about this comment or post links to info: is black coffee during fasting periods OK?

Good discussion here. It sounds like some IF studies have had positive effects even if the participants are taking black coffee, however, the caveat is that they don't know whether not having black coffee would be more beneficial.

If people are interested in learning more about fasting, I put together a few visual guides on it here - http://impossiblehq.com/nutrition/intermittent-fasting I also highly recommend the zero fasting app for tracking. Super simple and really clean app that makes tracking fasts simple. Start small and see how it goes. I find the 16/8 routine tends to work best for me personally with 36 hour fasts sprinkled in every c…

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.

On the rare occasion I have fasted for a couple of days, I noticed I was more focused not less. Physical exercise I would not recommend though.

Earlier quoted context omitted.

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.

Can you elaborate on what you ate? Curious.

Anecdote: I tried intermittent fasting for 11 months with very, very little to show for it. I did the 18 hours off and 6 hours of eating plan. I have also tried a strict vegetarian diet for 6 months with no real changes in blood work. My Cholesterol didn't move to the dismay of my PCP and myself quite frankly. Biology: I am a professional Firefighter that ran 1000 miles and bicycled 250 miles during this time frame.…

Yeah... there are no nutritional absolute truths unfortunately. Some people have high LDL that is relatively resistant to lifestyle intervention, probably due to genetics. At least there is the option to take a cholesterol lowering drug.

I don't know the size and strength of the beer you are drinking, but maybe you could try cutting that out.

How do you maintain energy levels through a 36 hour fast? Edit: Thanks all! This’ll help me progress from 16/8 to consistent longer fasts.

While I haven't done 36, 24 is relatively easy. The idea that your body needs constant food intake is a modern myth. It's mostly your mind that's been programmed to want to eat that often. Also, once you eat the insulin spike triggers the next wave of craving, and so on. Fasting is not the same because you're well, um, fasting.

> The idea that your body needs constant food intake is a modern myth.

Modern food intake also trains the digestive tract (most notably stomach) to never be empty, and we end up confusing signals of hunger with an empty stomach.

I heard that Japanese (or was it China? Korea?) people have this rule of thumb of eating only up to ~80% of stomach volume; no idea if it’s factually true but having this rule of thumb of not filling myself to the brim as we seem to culturally do currently seems to be extremely positive I’m my experience.

Letting go the social baggage of “bon vivant” and “oh my god I’m so full this was soooo good” seems to be just as hard as not smoking when many around are smoking.

“one should eat to live, and not live to eat” says Molière, but even being acutely aware of that, I struggle to fight the deeply ingrained social pressure, as even most foodies/fasters I know seem to subscribe to this “all you can eat” way of life (although with healthy food)

Goddamit when I was feeling great, all sporty and fit (athletic even, dare I say) everyone was saying I was too thin, and now that I feel like shit having some 10+kg excessive weight to shed, everyone around says there’s no need to, and worry a lot when I don’t take a second or third serving.

animal-product only ? No veggies?
