Is fasting continuously for months permissible?

Question

Is it permissible to fast continuously for months. Prophet saw asked young men to fast if they are single. So is it encouraged? I feel very peaceful and relaxing while fasting continuously. But I heard that it's not good to health. My family and friends discourage me and ask me to do alternatively. Please give advice.

I just want to say: I admire your will.

This is the Hadith you need to read.

Sahih Al-Bukhari - صحيح البخاري

30. Fasting - كتاب الصوم 55) Chapter: The right of the body in observing As-Saum. Narrated Abdullah binAmr bin Al-`As:

Allah's Messenger (ﷺ) said to me, "O Abdullah! Have I not been informed that you fast during the day and offer prayers all the night." Abdullah replied, "Yes, O Allah's Messenger (ﷺ)!" The Prophet (ﷺ) said, "Don't do that; fast for few days and then give it up for few days, offer prayers and also sleep at night, as your body has a right on you, and your wife has a right on you, and your guest has a right on you. And it is sufficient for you to fast three days in a month, as the reward of a good deed is multiplied ten times, so it will be like fasting throughout the year." I insisted (on fasting) and so I was given a hard instruction. I said, "O Allah's Messenger (ﷺ)! I have power." The Prophet (ﷺ) said, "Fast like the fasting of the Prophet (ﷺ) David and do not fast more than that." I said, "How was the fasting of the Prophet (ﷺ) of Allah, David?" He said, "Half of the year," (i.e. he used to fast on every alternate day). Afterwards when `Abdullah became old, he used to say, "It would have been better for me if I had accepted the permission of the Prophet (ﷺ) (which he gave me i.e. to fast only three days a month).
