Fat loss is primarily a function of diet.
You could run all the miles you wanted, lift as much as possible, but if you're still eating a terrible diet, then your results could be minimal.
First, you are a 230lb man, so why have you chosen to eat only 2000 calories? Yes, fat loss requires eating fewer calories, but for a man of your size, 2000 calories is almost like crash dieting. To figure out how many cals you need to consume:
BMR (basil metabolic rate) = 66 + ( 6.23 x weight in pounds ) + ( 12.7 x height in inches ) - ( 6.8 x age in year )
Then take that number and multiply it by one of the following activity levels:
If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2
If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375
If you are moderatetely active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55
If you are very active (hard exercise/sports 6-7 days a week) : Calorie-Calculation = BMR x 1.725
If you are extra active (very hard exercise/sports & physical job or 2x training) : Calorie-Calculation = BMR x 1.9
Then subtract 500-750 calories from that number to get your target amount of calories.
From my estimation, you will probably need to consume around 2,500-2,800 calories.
Yes, you can go ahead and eat 2000 calories, but realize you will lose fat at a rate so fast, that your skin will not catch up (resulting in loose skin). Also, you will possibly burn out and plateau sooner than you'd like.
Diet should have a good amount of lean protein (my golden rule is to consume at least 1g of protein per 1lb of lean body weight. Like others have said, avoid processed foods and go for real, whole foods, that you cook yourself.
Exercise: mix-up your cardio--don't expect to lose fat effectively if you're planning to jog the same # of miles every day, for months and months. Change the distance, change the intensity, and change the activity (treadmill, jump rope, swimming, bike, etc.)
Find a good weight-lifting routine. Skip the bicep-curls--you want to workout the biggest muscles of your body to burn more calories (legs, back, chest).
Good luck.
