Good diet plan for a guy?

Alright. I've been working out hard for quite a bit of time, and am happy with the results. I'm about 200 lbs., but at 6'1 I'm pretty slim from the side. The only problem are my obliques, which continue to remain unchanged despite the development of my abs and chest. I read that a good diet along with the exercise can help get rid of my slight love handle problem, but most diets I found are for women. Can someone give me a good calorie count for an 18 year old with my stats?
