As far as diet goes, just focus on getting adequate protein in your diet (about 1-2 grams per body lb). For you, that's about 121-242 grams of protein a day. It can be done! Just look into a protein supplemet to help you acheive this. Optimum Nutrition whey protein is a personal favorite of mine. It tastes good, absorbs well, and is very convinient for shakes. Other than that, find a balance in complex carbs and healthy fats. when you want to lose fat, it is more effective to lower your carbs along with your caloric intake. What I personally do is carb-cycling, which consists of going about three days with low carb intake (<60 grams) and one day with a higher carb intake (between 120-180 grams). Protein intake always stays constant. This way, you are tricking your body's metabolism so that it doesn't get used to you eating a certain way and therefore stop letting you see results.
