Intermittent fasting — 3 Days no food no drinks
Only water is allowed
4 Years ago I ran an interesting “scientific experiment” on myself for the sake of curiosity. I decided to go on a full fasting mode for 3 days, nothing but water. If that wasn’t clear, I’m going to say it again: No eating food! No juice! No coke! No fruits! No vegetables! Nada! only allowed thing is drinking water!

Why
I’m going to be honest with you, my mind phases out sometimes, I get those weird ideas, and what’s even weirder is that I did it. examples of those moments is me today thinking about this and deciding to share my notes and thoughts about that experiment on my blog. So, you ask **why? **I say:
Why not! 😉
Environment And Context
It’s very important for the readers to know what was I doing those 3 days and to know if I was pushing myself or just sleeping it through.
Well, back then I was in University which was a 1 hr bus drive from my house. So, I had to wake up around 630 AM every day, get ready, catch my bus, and be there around 8:30 AM. At Uni I had to attend around 4–5 lectures of 1.5 hr long, 1 hr lunch break in between and I had one Basketball game in the 2nd day. I Finished around 530 PM on those 3 days, meaning I reached home around 630–7 PM depending on the traffic in each day. After that, I went to hang out with my friends for ping pong and pool game the 2nd day, and on the 3rd day, we went for a coffee (took water myself 😅).
As you see above I had my hand full all those three days and oh! forgot to mention, I had to study and revise at night what I took at uni.
That’s pretty much it.
Context:
- Started very healthy (no pains no nothing)
- My weight was 82 KG
- Average eater.
- Big snacks lover (meaning, I always have to munch or drink something mostly healthy stuff).
Now For The Stats
Of Course, don’t expect real medical terms and proper stats. but, just what a human eye and brain can see and observe written on papers.

Day 0 (13/10/2012)
Total failure. I did it till midday for 9hrs. but then realized that it was my friends birthday, so I had to stop it. but, it was a good trial and preparation for the next day.
Day 1 (14/10/2012)
Big day! So, I woke up around 5:30, and I need to mention this, I’m a sweet-tooth.
9 AM: I was already craving for some chocolate 😝. but, this is still like a normal day. And I did some exercises (push-ups, setups, pull-ups).
3 PM: Started feeling a bit tired so I took a 15 mins nap.
6 PM: Started to feel fatigued. but, in general, I was trying to notice the following (based on small research I’ve done):
- Sweat smells very normal. but started feeling a cold sweat coming out which was a bit weird.
- Urine: Color is still normal just a bit darker than the usual.
In general, I was finding it weird that not a lot changed. but, I guess my body was still using from whatever energy still there from the day before.
9 PM: Tried to find anything that I can do to stop my mind from thinking of food. so, did some homework and some hardware programming. I was feeling some stuff though by then:
- A bit of sore throat (not sure why?)
- Small handshake: I guess that was normal because of the exercise I did early in the morning that day.
11 PM: Went to sleep
- Started feeling a bit of a blur in my eyes (probably because I was awake since 530 AM).
Day 2 (15/10/2012)
Night Time: It was crazy, I woke up like 4 times and all I had in mind was:
I’m not going to eat today.7 AM: Woke very tired dragging myself out of bed, had to run to catch the bus (which exhausted me).
3 PM:
Physically:
- A little bit pale and hands look a bit yellowish.
- A little shake in hand
- A whole-body fatigue
- Started losing balance a bit (because it was effecting my blood-pressure which in-turn effects my ear and balance system).
- Urine is way darker than the day before.
- Feeling hungry 4/10 still.
Psychologically:
- Less talkative (maybe because of energy, but maybe also mentally tired)
- No depression or anything like that.
- I feel more motivated to do this experiment more.
Of course by this time: whomever I’ve told about the experiment, they said You’re crazy dude!6:30 PM:
- Slept for 2 hours, my Biceps hurt like hell (definitely because I’ve played Basketball during the day earlier)
- I felt a bit like fainting for a bit.
10 PM:
- My legs really hurt, started feeling pain whenever I’m walking (same pain you get when you walk for 5 hours straight)
- Biceps hurts more now plus some shoulders muscles now.
12 PM:
- Heart beating really fast by now
- Feeling scared of fainting because of the pressure drop.
- Headed to sleep.
Findings of the day:
- Always thinking about food, whenever I’m free or minds wandering.
- Weight is now 77 KG (lost around 4–5KG already)
- Since food can be a reward sometimes in the brain. This affected a bit of how I do stuff and finish things.
Day 3 (16/10/2012)
It was the Toughest! had to walk like a drunk all day esp. the evening time.

8 AM:
- Woke up with full-body fatigue.
- constant feeling of a bit of dizziness.
- All joints hurt a bit. especially the foot joints!
7 PM:
- First time I poop in the last 3 days
- Felt dizzier.
- Obvious loss of balance (probably caused by the lack of sugar)
- Weirdly I still have some energy left (I had a small wrestling game with my brother) I won if you’re interested :P.
8 PM:
Psychologically:
- Too much thinking of food.
- Thinking a lot about me being hungry.
Physically:
- Joints pain increased a lot, especially the knee joints.
- Stomach-ache.
10 PM:
End of the experiment!Findings of the day:
- Weight is now ~75 KG (lost around 6–7KG already)
- Pee color is brownish (not good 😅)
