Losing weight after gallbladder removal?

hello everyone, i have a question, i had my gallbladder remove almost 2 yrs ago, since then i cant eat too much, my portion size is small, only fatty stuff i eat is chicken, thats the only thing that dont mess with my tummy, i also develop IBS and Acid Reflux which has been ruining my life, i have lost alot of weight like i went from been 280lbs to 186lbs after removing my gallbladder, even if i sometimes eat junk or too much am still losing weight, my doc was concerned so she ran blood test everything was normal except my hormones was messed and also had ultrasounds done and my liver is fatty which i dont eat fatty stuff so i was confuse why this is happening,she believe my liver is hanging on to extra fat from my body that wont leave, she didnt seem concern cause my blood result was normal, is it normal to be losing so much weight after gallbladder removal? maybe cause am not eating fatty stuff like i use to?
