Does anyone else also start to experience heart palpitations after 3 or 4 days of fasting? The heart beats are regular but fast and hard. This interferes with sleep and makes it impossible to go beyond those few days, as it just gets worse. I do drink water during the fasts.

Some people fast with a "snake juice" of electrolytes. Maybe that's what your body needs?

Due to pancreatitis, my stomach has been closed since October 2020. So I have been effectively fasting for a continuous 18 months. all I think about is food.

Have a family member dealing with this also. Has lost an incredible amount of weight (but not "good" weight loss) and has insulin issues and also neuropathy. Horrible disease and it seems the treatments aren't very effective either.

While I’ve done similar fasting myself, with the same wondrous effects you describe, I want to point out that it seems this might be a lot harder to do for young women (in child bearing age). My partner tried to replicate what I did since I was hyping it so much, and failed miserably. Later we learned that the female body reacts much more violently to the lack of calories than male ones, and its a lot harder for them…

I'm kind of doing "one meal per day" right now, not because I'm fasting on purpose but just because I don't enjoy eating (or cooking) more than once in a day. I mean I like to cook but doing it for over an hour every day just becomes a chore. I was under the impression that this was really unhealthy though. My BMI is 19 so I'm close to being underweight. Isn't this unhealthy? Do people fast and not lose weight?

Weight gain or loss is all about calories in versus calories out. It is possible to exceed your TDEE in one meal, just a little difficult or unlikely. Whether or not this is unhealthy or not is dependent on the person. I will say that I worry that many in my generation are developing eating disorders and calling it fasting/OMAD/etc.

Three things could be happening:

1. The heart is a giant muscle and needs balanced sodium and potassium to function. There are electrolyte blends in the market designed for fasting to help with this.

2. You're insufficiently hydrated because you've reduced your drinking intake or haven't replaced the water you would get in your food itself.

3. The body is in a state of hunger and alertness. Your sympathetic nervous system is ratcheted up in awareness of this and in search for possible food. To calm this down, practice diaphragmatic breathing exercises.

I'm not sure if starting something like a 7-day fast without medical supervision is a good idea, and I'm also not sure if any medical professional would allow you to do that, just thinking out loud. Don't you think it's too dangerous to name it essential life experience and recommend it to random people on the internet? I'm really asking, I'm not knowledgeable about this at all, and my questions stem from pure gut fe…

I also question if 7 days is safe for most. I don't recall exactly when and a quick search now yields a lot of random gimmicky fasting product sales sites with blog posts written to generate traffic that aren't scientific enough, but I do recall that there is a point (after 72 hours?) where your body starts breaking down muscle and that prolonged fasting is dangerous as your organs get hit next? Perhaps someone here…

Not to be snarky, but reading the linked study would be helpful here. Your body is quite intelligent when it comes to drawing on its energy reserves.

I’m sure many would be quick to jump to numbers on how much you are supposed to consume/burn in a day, but I really don’t think eating too little or too much is by itself an indicator. The underlying psychological issues and associated stresses is what IMO qualifies as “unhealthy”, in which case corresponding under- or over-eating could result in malnourishment or excess weight[0]. However, in absence of these issues…

> I’m slightly underweight, and I can eat quite a bit without gaining much weight

Interesting! Here's a challenge for you: could you buy — and eat — 5000 calories of chips/candy/soda per day for the next 90 days. You may not walk/run more than 5km/day, nor engage in other exercise for more than 30m/day.

Please weigh yourself before & after this experiment.

One more reason to become Muslim.

Religious fasting has little to do with the therapeutic ones. For a start, they are too short and are not even 24h. Second, the idea is usually to binge on cakes everyday at sunset.

People talk about these "wondrous" effects of fasting. All I got was headaches, tiredness, feeling sick and constantly thinking about food. I lasted 5-6 days, tried to keep my electrolyte intake as well as I could, and it was miserable. I managed to eat very little (like 500-600kcal) on day 6 and really gorged myself on day 7 despite knowing about refeeding syndrome, I just couldn't help it. That was during my prime as well, I woudn't try it again now. Maybe it does indeed work for some people due to metabolism disorders or something, but it really didn't for me. And for god's sake don't do 10-15-20 day fasts without medical supervision.
