Hi
Thanks for choosing HCM for your query.
Age, gender, duration of the problem, alcohol or drug intake not mentioned.
I have gone through your problem described in your case.
Increased echotexture on 
ultrasound is reflected in the form of 
fatty liver ( due to deposition of excessive fats).
The first thing to be avoided is stop consuming alcohol (if you are an alcoholic), foods to be avoided are oily vegan and non vegan dishes, fast/junk foods, avoid using larger doses of 
Paracetamol.
Your diet should consist of leafy green vegetables, fresh fruits, baked white meats like poultry, fish and eggs.
You can also use olive oil, black seeds (nigella sativa) which have proven to be effective in preventing 
liver damage, drink lot of water.
Vegetables and fruits contain essential vitamins and anti oxidants capable of preventing your liver from the 
injury.
Hope your query has been explained, give your valuable feedback.
Prevention is better than cure, take care of your health.
