Actually, exercise can be very time-consuming, though some of that is up to you. On weights days, it takes two hours out of my day -- 15 minutes of clothes-changing and protein-shake-drinking, 20 minutes each way driving to the gym, and about an hour of actual working-out. Cardio isn't so bad, but that's just because the workout's shorter. Sure, it's my choice to live way out from the nearest gym, and to work out primarily at the gym instead of at home, although I do have good reasons for both of those choices. So it does wind up taking a massive amount of time from already-overly-busy days, and yes, I have felt guilty and/or resentful about spending all that time at the gym, and have taken breaks during periods of really extreme work.
A quick point on the running: it isn't the best choice of exercise for many people, especially those who are carrying around extra weight. Plus, you generally have to be in pretty good shape to start with to make 5 miles ~ 8mph. I thought I was in good shape from months of the elliptical, but I've started on a run/walk program lately, and 30 minutes of that is a pretty tough workout. Unfortunately, it apparently only burns about 120 calories, according to both the machine and Fitday; that's fine with me, since my primary goal is to build up stamina for actual running, but it doesn't do much for weight loss.
Exercise is a wonderful thing, but Diane, you're right that it's of limited use in weight loss. True, it makes a huge difference once you get close to goal and start focusing on toning your shape, but if you're trying to remove 50 lbs or more, moderate exercise alone will not do it in the time frame most of us are looking for. Simple math tells you that to lose a pound a week from exercise alone, you've got to burn 500 calories a day, 7 days a week. That's an hour of biking (outdoor or stationary) or fast lap-swimming, an hour and a half of jogging ~ 5mph, two hours of low-impact aerobics or Stairmaster, or a whopping *three* hours of fast walking or water aerobics (the best choices for beginning exercisers and people with more weight to lose). If you're doing a half hour or an hour of any one of these three or four times a week, it works out to roughly 1/4 lb per week, which is almost imperceptible. To be sure, it's much better than gaining 1/4 lb per week, but I know I wouldn't have had the patience to lose my own weight over a period of more than 4 years!
