Can fatty liver and hypothyroidism be the reason I can’t lose weight?

I am 76kgs over 5'3.7 ft. I am obese and suffer from fatty liver. I cannot lose weight. I tried liver tonic over two years but wasn’t able to get any lower than 76... upon that I have hypothyroidism. I don't know how to deal with it.
