I am 6ft.,3in. and 171lbs.
My diet is 1800 calories with less than 60g's of carbs and at least 120g's of protien. I run 8 miles in 62min 3 times a week. I lift 3 times a week.

Hears my problem, I am not lean. There is still fat around my lower ab section. I cant for the life of me figure out how to get rid of it. I dont want to go any lower than 171lbs., because I dont think its healthy. Is there anything I should change to get better results.

My advice is to not count calories, but count carbs. Have less than 30 a day. Also, I believe the protein is too high.

But what you're asking for is sort of a paradox. If you believe that you are not lean enough, and you're at 171, and you don't want to go below 171, then it does not make sense. Either you want to lose fat or you don't? Don't look at the scale. Unless you're training to be in a particular weight class, I don't know.
