A common, but simple error. Muscle weighs more than fat. If you strength train, your muscles will constantly be repairing themselves well after you've done strength training. This repairing burns far more calories than the initial 900-1400. It will be far more than that.
Phelps spent at a minimum of 5-6 hours in a pool a day. His routine (assuming what is listed is correct) highlights all of the stuff he does http://workoutinfoguru.com/mic... If you're spending 5-6 hours swimming then you need to consume 10,000+ calories. Looking at Phelps diet he's eating a lot of grains, an energy drink, and could most definitely eat those pizzas you're referring to.
He also incorporate compound lifts into his training. Compound lifts include the bench, pull ups, push ups (really just a bench), squats, and deadlifts. These work the most muscles in your body and give you the most bang for your buck.
Word of advice for you to help speed up your fat loss. Stop looking at your overall "weight" and saying I need to lose X. Weight is a cumulative number that fails to show the full picture. Instead, find out what your body fat percentage is. This number is what you really need to focus on and bring down. Muscle is infinitely more attractive than adipose tissue.
Next eat a diet high in protein. Pick either animal fats or carbohydrates. If you pick both you will get fat. One of the other. If you lack self control, consider trying the paleo diet. This will force you onto a high protein and fat diet while lowering your carb intake.
Good luck, personal fitness is a goal that every one should esteem to be the best at. People instinctively follow those who are in better shape.
