If your goal is to gain muscle and lose fat, you cannot do both at the same time. Make your self a program to hit the gym, do lift training for the muscles after that hit cardio for 10 minutes, and every week add 5-10 more minutes cardio. Start your diet with 2300 kcal per day and try to discrease it with 100 kcals per week. You will lose enough fat, your gail is to lose fat. Not your weight tbh, losing weight is including muscle and you wanna try to stay out of that. Try to burn the fat with just the lifting, cardio and minimum in this case 200 kcals in take per day, would be enough to burn pure fat. If you do a crash diet, it won't work. You will lose most likely water and muscle, muscle weights 3 times more then fat keep that in mind. So you'll think that you've lost fat, but infact you have not. It will also be harder for you to gain muscle back as you've lost kilos by crash dieting for nothing. If your a natural and are experienced and know every muscle in your body, your nutrition is perfect and your rest. You could gain 5-10 kilos per year depending on your genetics. So don't waste your muscle on a crash diet, trust me.
