I belief were in the same age (24). I am 5'11, and currently weigh 165 lb. I was 195 at the most, i lost the 30 lb in two months. I have been eating mostly whole foods, and chicken/turkey with vegetables throughout the day. I have started lifting free weights last month. Started running at tracks, and streets as well.

Should I start ab/core excersizes? My circumference of the stomach is about 35 1/2 inches. It's a big number, but I was around 38 in January.
