My tip is to not do that.14

Unless you’re doing this for religious or medical reasons (which would be supervised), don’t do it5

I have done this (not for weight loss), and I absolutely don't recommend it for weight loss. It was a very tough experience, I was too tired to get any work done, and if anything I gained weight long run due to the cravings I developed for rich foods which I'd never eaten prior to the fast.
You are much better off going for small sustainable changes if your goal is to lose weight and keep it off.5 -

Yeah, no. That sounds like a bad plan.2

Not sure why this comment is getting flagged. There are studies being done about the effect of long-term fasting on the body, including the sped-up process of autophagy.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3106288/Sporadic short-term fasting, driven by religious and spiritual beliefs, is common to many cultures and has been practiced for millennia, but scientific analyses of the consequences of caloric restriction are more recent. Published studies indicate that the brain is spared many of the effects of short-term food restriction, perhaps because it is a metabolically privileged site that, relative to other organs, is protected from the acute effects of nutrient deprivation, including autophagy.17 We show here that this is not the case: short-term food restriction induces a dramatic upregulation of autophagy in cortical and Purkinje neurons. To our knowledge, this is the first demonstration that food restriction leads to in vivo neuronal autophagy. Our data extend recent reports in tissue culture systems,18,20 and have implications for individuals who, by choice or necessity, have limited food intake. Our findings also may have therapeutic implications, as outlined below. Autophagy is sometimes referred to as cellular “cleansing”, and our observations provide an attractive neuronal parallel to the organismal benefits that, historically, are perceived to derive from fasting.
Our observation that a brief period of food restriction can induce widespread upregulation of autophagy in CNS neurons may have clinical relevance. As noted above, disruption of autophagy can cause neurodegenerative disease, and the converse also may hold true: upregulation of autophagy may have a neuroprotective effect.

I've read a fair amount about it and may give it a go in January. At the moment I've adopted a low carb diet to address type 2 diabetes. I suspect that this diagnosis won't allow me to fast more than 12 hours or so at a time until it's firmly under control.
Don't let the haters get you down. But before you try something like this do your research. Real books by real doctors - that means more than one!!

To actually answer OP's question, I've done a 3-day fast just to try it out.
I stuck to low-calorie liquids like water, sugar-free jello, broth, diet pop and tea.
I felt pretty good the first day. A couple hunger pangs in the afternoon, and it was challenging falling asleep when I'm not used to going to bed hungry. I woke up wide awake and bouncing off the walls with energy. Second day was a little easier. Third day was TOUGH, I felt tired and just wanted to eat again.
It actually did temporarily help me out with my food cravings. Before the fast, I felt really controlled by food and like I needed junk food all the time. After the fast, I had a psychological mind shift and felt much less reliant on food and cravings. I just felt more in control. Now - I said temporarily! Because eventually I fell back into my normal eating habits. But if you did a 3-day fast, say, every month - the psychological benefits may stick around.
I also did a 2-day liquid fast leading up to a colonoscopy and it went very well. The third day seems to be the tricky one.3 -

A potentially useful series of articles for those practising or considering practising Intermittent Fasting, which I myself used to do and still do periodically.4 -
IF promotes autophagy just fine, as does exercise.
And it's not something extreme like prolonged fasting.2 -
Muslims do it for a while month in the month of Ramadan. It's usually around June, July I think.1

Fasting for Ramadan begins just before sunrise and ends at sunset
Also as thier calander relies on the moon it actually changes every year so while the last couple of years its been in the summer time it isn't always this way

My sister used to do a lot of fasting. She lost all her teeth, and a lot of her hair. She has a lot of chronic health issues. I don't recommend it.7

seems like it has its pros and cons. i guess i will see how long i can go untill i cave.7

My experience: Felt horrible.
My results: landed in the hospital (intestinal blockage isn't fun).
My tips: don't do it.3 -

While you're at it...
Don't tug on Superman's cape
Don't spit into the wind
Don't pull the mask off the old Lone Ranger

Your body is always breaking down and rebuilding itself; it doesn't need anything to promote/initiate that process. With a fast, you don't give it the materials to rebuild, so you lose precious muscle mass. It's great if you want to end up skinny fat.6 -
This actually sounds rather dangerous, and I think unsafe habits is against the forum rules.4

From what I have read, the body reacts to VLCD just like fasting. It isn't necessary to go completely without food.

But it's necessary to get enough food to fuel your body, which unless you're under a doctor's care VLCDs do not do.1 -

I find your "making strides towards health" badge funny since your recommending a VLCD by the sounds of it and if your not id edit it to be more clear OP's liek this tend to grasp onto what they want to hear vs all the other answers. Although this OP seems to have made their mind up long before posting. Sad.1 -
