Earlier quoted context omitted.

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.

I have been on IF for almost three years and started recently on 36 hours once every three weeks. If you can do 24, 36 is not too much of a problem. My last 12 hours of the 36 hours is sleeping, so I don't think about food or feel hungry when I am sleeping. Also, I ended up doing it for 38-40 even though my intention was to do it for 36 hours because of my sleep.

IF is the only diet I can follow, I have been on it for three years, I think I am going to do it for life.

I am not affiliated with it, but check out idmcommunity.idmprogram.com/

Also, Dr. Jason Fung is an authority on IF, if you want to check out his videos on YouTube.

Slate Star Codex published an article investigating whether intermittent fasting extends lifespan, and found that the research is flawed: https://slatestarcodex.com/2019/12/12/acc-does-calorie-restr...

Luckily, whether intermittent fasting will work for you is really easy to test with an N = 1 study where you are the 1.

This is only true for people who have something they want to change. In practice that basically means weight or a biomarker that’s practical to measure, like fasting blood glucose. For people with normal weight and insulin response, the possible IF benefits seen in mice are difficult or impossible to measure. For example, identifying autophagy in a standard CBC with diff is experimental at best (https://pdfs.semanticscholar.org/08a3/bf79055d69da0fe7305255...).

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.

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.

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?

There needs to be something with calories to metabolize to end a fasting period, coffee has low/no calories, you can have up to a fifty calories before the fasting is broken. Caffeine is metabolized, but has no caloric value so I don't think it would count.
