I am hbv immune tolerant, with consistent mild pain in liver. My doc says don't worry n reduce weight to 65kg right now I am 72kg. Pls suggest?

Hbv. I'm not sure what you intend by "hbv immune tolerant". If you can clarify, it will be helpful to better answer your question. However, with consistent mild pain in liver, you may want to check your liver function test and also liver ultrasound, to further evaluate your liver, if not already done.
