First, you gotta tell us your goals. You cutting? bulking? maintaining? Thats important for developing your diet.
At 245 lbs, you don't need 5000 calories a day unless you're bulking. If you are looking to cut some fat, you need about 3400-3500 cals per day.
Drop those hamburgers cause that's just crap. Get some real food...you cannot live off burgers, protein shakes, and junk snacks.
Keep your metabolism up with your frequent meals. With your calorie needs, you can eat a 450-500 calorie meal every two hours, eight times a day. That'll take care of a sixteen-hour-day. If you have a shorter, 14-hour-day, have seven meals of 560 cals. Watch the size of your meals. If you eat too much at one time, your body will store the extra, probably as fat.
Plan your meals ahead of time to prevent your snacking tendancies between meals. But if you eat frequently, you won't be hungry, and thus, won't feel the urge to snack out.
You don't necessarily want to totally decrease or eliminate your fat intake. Eating fat is very important in a diet.
It is really okay to eat more than just chicken breasts. Not only are you gonna kill six chickens a day, but you will deprive yourself of nutrients not supplied in chicken breasts. Also, if you eat only chicken breasts that total 1300 calories, you are gonna go into starvation mode and store everything you eat.
You need a well-balanced diet of protein, carbs, and fats.
1-1.5g protein per lb of bodyweight. You can still have your chicken breasts, but twevle a day isn't necessary. Protein is also in tuna, salmon, and other fish, lean red meat, nuts, eggs, and cottage cheese.
Probably get around 1100-1200 calories from carbs. (measure this by the calorie rather than the gram). Good carbs include brown rice, whole wheat bread, and oatmeal, as well as fibrous veggies like broccoli. Have your carbs in the morning and early afternoon. Usually people have a carb breakfast, like a bowl of oatmeal or something. You shouldn't have any carbs in your last couple meals.
Eat about the same amount of fat calories as carbs (1100-1200). Don't be frightened by eating fat and avoid it. But your burgers are gonna give you only crap fat. Basically, you want mostly monounsaturated fats, some polyunsaturated, and limited saturated. Nuts, flax, olive oil, whole eggs, and natural peanut butter are the best sources of fat.
Lastly, post your workout schedule.
