There are a couple things to consider when participating in any endurance sport. First, you need to have an adequate amount of carbs & protein in your system before you start. Some people can eat a small meal/snack an hour before they start, for others it may be that 2 or 3 hours works better. You shouldn't take in too much protein, but you will need some. Taking in too much protein causes your muscles to produce ammonia, which makes you tired much faster. If you exercise for more than an hour, you will need to eat something that has carbs & a small amount of protein during the exercise.

After exercise, you have a window of about 30 minutes in which your body is most receptive to receiving carbs & protein. Eat something during this period to help your body recover quickly and to maximize the benefits of the exercise.

Exactly. Cardio on an empty stomach is bad stuff, which is why not many people recommend running early in the morning before you've had breakfast. It may seem like you're burning more fat that way, but in actuality you're just causing your body to starve further, and eat away at your muscular gains.

You have glycogen stored in your body even if you stomach is empty, and your body isn't going to cannibalize much muscle if all you do is a 45 min swim.
