I have a few lbs of fat on me that I want to lose but I also want to gain muscle mass. So what should I do;

a) Maintain calories and eat out weight training?
Thinking: High protein diet and being a newbie may enable fat loss and weight gain for a short while. Then switch to b or c

b) Have a calorie deficit but maintain weight training schedule?
Thinking: Lose the fat first but risk losing muscle mass, if so what should my BF% be, when should I switch to c

c) Have a calorie surplus and eat out weight training?
Thinking: Build muscle and hopefully fat will burn out in time by maintaining a strict low fat diet.

Please vote a, b or c
