The most effective way to reduce your calories is to weigh, measure and record the calories you take in, to track exactly how much you are eating, and the activities you are doing when you are eating them. Lots of people munch on things without paying attention to portion size or amount, especially if they are distracted by TV or work. Having a record allows you to see where you are spending your calories, and helps you make decisions about where you can cut back.
It's also very important to make sure that you're eating enough!! You can get a fairly good estimate of what your body's caloric needs are at the Mayo Clinic website: http://www.mayoclinic.com/health/calorie-calculator/NU00598
It only takes a very modest reduction of about 150-200 calories a day to make a difference in your weight loss efforts. The weight will come off slowly, but your body won't really notice a calorie reduction of that amount, so you won't feel hungry or have cravings.
It also helps to have your meals and snacks spaced between two to three hours apart, and include some protein every time you eat, so that your body will burn the calories at steady rate, and you won't have dips in your blood sugar that trigger cravings.

Also, make sure you're getting enough sleep. Sleep deprivation is linked to weight gain and difficulty losing weight. If you haven't had a check up recently, maybe it's time to have one, and specifically ask for your thyroid hormone levels to be checked.
Try some regular strength training exercises. Increasing your muscle mass will allow you to burn more calories. Don't forget to include cardio, because that's how your heart muscle gets its strength training exercise. Brisk walking is a very good choice - all it costs you is a good pair of shoes every six months or so.
Weight loss is a big challenge for lots of people, but you're close to your goal weight... they always say those last 10 pounds are the hardest to get rid of! Good luck!
