Eating out can be tough. A burger and fries can be anywhere from 1000-3000 calories.
Dunno how tall you are, but at 1500 cals/day I lose around 1kg/week. 1800 is maintenance for me. I'm 5'11 and Asian, the latter part means I have to eat less (yes, whiteys can eat a bit more).
Use MyFitnessPal to log your calories and activities. Use a HRM to track your physical activity. Walking consumes very few calories BTW.
I lost over 50 lbs doing this, and I'm so freaking fit now that I got a discount on my life insurance because my blood work and BP were excellent.
