<human>: I'll try to keep this short and sweet. I am a 22yo male, 5' 8", and 200 pounds.  My job is working on the computer so I sit around all day. My diet, frankly, sucks. I don't own a scale and only know my weight from a recent doctor's vist. It has been the same for about 3 years now, and I probably keep myself from getting any fatter from walking everywhere I go since I live in New York City. I want to become healthier and change my body image for me and my girl friend.

To start off, I just checked the calorie calculator from the FAQ, and going to try to limit my calorie intake to 1600 a day. I downloaded a calorie tracker app on my phone to keep track. I plan on going out and purchasing a scale right after I post this, to get daily weigh-ins that I am going to recored, along with the daily calorie intake. I am thinking of also taking weekly photos of myself, maybe less if progress takes longer than I thought. For working out, I am going to keep my long walking commutes as my activity for now, and see where this approach takes me. I walk about 20,000 steps a day, as reported by my pokemon pedometer ;) How does all this sound? How can I improve my approach?

Can you condense the text into three sentences or less?
