I doubt it. Ask your doctor about carb counting. Basically, think about what you eat and try to cut down on carb heavy foods like bread, potatoes, cereals and pastas. Don't eliminate them altogether because you do need some, it is just that it is way too easy to eat too many. Try to replace those you cut with protein rich foods (meat, cheese, eggs) as that tends to keep you feeling more full for longer. Don't worry so much about how much stuff you eat as what stuff you eat. Also, just try to work in some more activities in your daily life. Walk a dog, walk to a store nearby rather than take the car or bus, take stairs rather than an elevator, take a little walk at lunchtime. Just little things to make you more active. If there is a sport or activity you enjoy then it is even easier to make that lifestyle change.
Remember that if you don't enjoy something, you're unlikely to keep it up long term: We are essentially visceral beings ruled by immediate desires. I, for example, could eat chocolate until I explode :-)
