I started eating after alot of loosing weight like i was 90kg and i loosed to 60kg so i started eating after alot of time and the next day when i weigh so it was 64kg and after that i thought maybe its normal but the second day it was 66kg and now from almost 2 months its sometimes 64,65 and sometimes 68 .... like if i diet for a few days so the weight starts to come backwards and if i eat again so it stays increasing like since 2 months i dont know whats my actual weight cuz it hasnt been back to normal. Water retention should flush and back to normal but thats not happeninh why ?
