I did lah. 1 whole month each time. Sometimes he drinks fresh juice maybe once a day. Like that cannot ah? Mati loh.

Yea. Orang gila...i dont know how he survive. He should be dead by now.

did it once , 4 days without food, pure water, i dun think worth it, go for healthy leafy green diet better. during 4 day water fast, ur breath smells so bad even open mouth the odour will come out

agree!

u're dehydrating ursel in the end tho!
bad for health 

Of course you can. The longest fast ever recorded (with vitamin supplements) was by this Scottish guy for 382 days.
Just to be clear, you need to make sure your electrolytes is balance during prolonged fasting. I'll have a bit of pink himalayan salt once or twice a day for that.

This is the link to the research findings.

Just to update, i broke my fast on the 10th day and eat normally soon after with no refeeding syndrome.
