So you already know how much you can lift (i'm guessing that's benching?), but really your main focus right now should be developing a proper cardio regimen. I was always an overweight person throughout my childhood and even into my first year of college, and I always felt I was hopeless. I tried all sorts of diet/exercise combinations even restricting my calories to 500 a day (btw that does not work at all so don't even waste your time on; i ended up gaining weight). Anyways about a year ago, I decided to pick up the one sport I hated the most and thought I could never be good at...running. At first I sucked at it and couldn't run more than three blocks. But then, I just kept pushing myself imagining the better looking and healthier me at the end of a long stretch of road. Over the year I went from not being able to run three blocks to running 10 miles a day with ease. I can outrun almost anyone I know, and there is almost no better feeling than that. I'm not gonna lie it wasn't easy and sometimes I wanted to give up, but as long as you keep trying you can't let yourself get down. So my best advice to you is it doesn't matter to much how much protein you take in or how many carbs or how many calories (though you should not eat less than 1500 or more than 2000 for someone of your height and age). Trust me, you just need to pick an activity that you hate and really stick to it and never give up on it, cause it will feel awesome when you get good at it. Everyone loses weight differently and most weight loss is trial and error, so just get out there and start getting your heart rate up and sweating, and eventually you will know when you are doing things right. The advice is simple, but its coming from someone who has struggled for 13+ years with their weight so it's from the heart. Good luck to you!!!!
