How much do you weigh? If your BMI is more than 25, you need to reduce your weight through exercise and diet. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV, Flu and Covid vaccines. Wish you good health!

Yes Life style changes will help. If you are like most patients who suffer from NAFLD, your weight is more than a healthy weight. So weight reduction is essential part of helping your liver to recover. This will require reduction in fat intake(avoid milk products and animal fats from meats(Especially beef and pork). Walk daily for 30-45 minutes and cut down on sugars/ sweets like all sugary drinks
