50 lbs down but more to go; 24 male 5'7" 218-168

I joined up around new years with the typical new years resolution for many years running and finally kept up with it!
Decided to post progress pictures since I have hit a major milestone but I am still losing. I don't know when I'll stop losing as I have never been this light in my adult life and don't know where my target body fat will fall weight wise. I do know I weighed 175 in 8th grade but thats the farthest back I can remember ( i was also shorter then).

Weight loss has recently slowed as I my wife just had our son and between him and studying for my medical licensing boards, I have no time (or so it relatively seems!)

Anyways, pics (the oldest comparison i have is at 209)
