I have recently went from about 240 to 160. I still have lower fat on abs and i cannot lose anything else. My calorie intake is about 1500 a day at least 200 grams of protein. I have tried cardio but i get winded walking and working out, much less riding a bike or running. I have tried to improve it little by litlle but to no prevail. I lift weights 4 times a week and dont know what else to do.
