You said you have a fatty liver. Have you ever been a heavy drinker, had sugar diabetes, high fats in your blood or used some type of medication for a good amount of time? Have you had any trouble with high blood pressure, chest pain or heart problems or have you had any trouble at all with high blood sugar? I have a similar problem that runs in my family and in the past 6 months I have lost 60 pounds for a joint problem but also this disease may cause me trouble at my age. My father has this disease and it seems to run in my family. I lost my weight by going on a low fat and very low carb with no simple sugar diet and exercise at the same time. I would ask my doctor before you go on this diet as it seems to take away a lot of hunger but is very rough metabolically. Also I was told that walking or swimming or lifting weights are excellent ways to get exercise. I would ask my doctor about which of these exercises you can do. I want to make one point though-please check with your own doctor on what type of exercise he suggests for you. So avoid fats and concentrated sweets and exercise away.
