Some good replies, one thing you can do that is very easy is to cut out your starchy carbs after 3-4 pm , in other words rice, potatoes, pasta etc are all cut out of your diet after 3-4pm in the afternoon, between that time and the time you go to bed just eat fibrous carbs ie salad, vegetables.... this way you still get to eat the food you enjoy you just eat it earlier in the day when you are still active and your body can process the carbs.
Another easy change you can make is the type of starchy carbs that you eat, White potatoes , white rice and white pasta are all considered HIGH on the "glycemic index" which means they are harder for your body to process and are much more likely to end up as fat on your body, try eating brown rice, sweet potatoes (yams) or whole wheat pasta as these are LOW glycemic carbs and your body will process them to use as energy and will not turn them to fat as easily ...
I have helped many people lose alot of unwanted weight over the years, the biggest problem with diets is they are hard to stick to and most people can't and won't stick to them.... I prefer to call this a lifestyle change, you eat healthier to get healthier !! go by how you feel and look instead of how much you weigh..
Changing when you eat more so than what you eat can make a huge difference.
When it comes to exercise walking is one of the best activities there are, it is low impact on your joints and muscles and it keeps your heart rate at its highest % of fatburning, when you keep your heartrate between 135 and 140 bpm, your body is burning almost pure fat.... as soon as your heartrate is higher it starts burning higher % of muscle
when you perform your exercises ( cardio) also makes a big difference, try doing cardio before you eat in the morning, as long as you keep your heartrate below 140 bpm you will be burning almost all fat, because you haven't eaten yet there will be almost no stores of glycogen ( stored Carbs ) in your body which means your body will convert fat to energy in order to perform your exercises.
These are just a couple of hints that should help you out.
