I'm an inch taller and around 5lbs heavier than you. I eat approximately (ever so slightly more, 2k-2.5k instead of 1.8k-2.2k) the same as you. I use a pedometer to make sure I'm moving at least 5 miles on days that I don't hit the gym (gym days are easy on that!). You're saying that by eating similar diets, having similar activity levels, and being of similar heights that we should weigh a similar amount? The hell you say! What wizardry is this?
