I'm a firm believer in counting calories. 1500 calories / day will result in a weight loss of 1-2 pounds per week for most people. Add in some regular exercise, and 2-3 pounds per week is possible. The 1500 calories has to be tracked, and sometimes portions weighed (4 oz. lean ground beef patty = x calories for example). I really try not to estmate, because it's easy to underestimate. Good luck, whatever methods you decide to use!
Ditto!
I was 190 pounds in December of 2008. I told myself I would be 175 by our June 2009 vacation. I hit that goal (gained 5 pounds on vacation

) and set a new one. The next step was to be 165 by April 2010. I hit that goal too...and gained 5 pounds back on vacation....I'm seeing a pattern. In December 2010, I was 165 pounds. So, that means that in two years, I'd lost 25 pounds

. It was slow, but I haven't gained it back. My current goal is to weigh 155 by April 2011....our next vacation.
I've done nothing but count calories. I learned to pay attention to what I eat. I still eat whatever I want, but I limit my calories to 1200-1500 per day. People tell me that I am not eating enough and "that's not healthy", but here are some examples:
Breakfast: 2 egg whites (~40 calories) scrambled with 2 turkey sausage links (~80 calories) and some spinach (FREE!) and an 80-calorie cup of yogurt. 200 calories for breakfast
Lunch: 3 oz of canned chicken (70 calories), 1 tsp chipotle mayo (20 calories), lettuce and tomato (FREE) on a 90-calorie Slimwich bun and a bag of Doritos (150 calories). Total of 330 calories for lunch.
Dinner (I work nights so I usually eat fast-food for dinner): McDonald's Southwest Grilled Chicken salad without dressing (It has a marinade on the chicken so it tastes just fine without dressing

) is 330 calories. If you must add dressing, it is another 100 calories. I get the salad and a bag of Apple Dippers (minus the caramel) so my dinner is 430 calories.
So, with those three meals, I am at 860 calories. If I want a Snickers bar, I can have one. I have about 440 calories to "play with" as snacks. I try never to "drink" my calories. I get my dairy and calcium from low-fat yogurt and cheese instead of drinking milk.
If you are like me and have a sweet tooth, here's a great recipe that I got from a friend at work. Apparently, it is very popular!
Take a 15oz can of pumpkin (not pumpkin pie filling, pure pumpkin) and mix it with a box of double chocolate cake mix. No eggs, no oil, just the pumpkin and mix. Divide it into 24 muffin cups and bake at 425 for 15 minutes or so. The chocolate masks the taste of the pumpkin, but the pumpkin gives the muffins that "heavy" texture. They are so moist that they taste like they are full of fat. In reality, they are just under 100 calories each! I also like to use spice cake instead of chocolate...it tastes like pumpkin pie! They are great for desserts or snacks and I like that I can eat 2-3 of them without feeling guilty.
I like the "calorie" method because it makes me think about what I am eating. I tell myself that I can either eat an entire bowl of lettuce, tomato, chicken and green peppers....or I can have a 3 Musketeers. I have to decide how hungry I am. If I want the candy bar, I eat the candy bar, but then I go hungry later. This way, I am not depriving myself of what I want so I don't feel "burdened" by a diet.
