The best way to see if you are losing weight is to take photos or video of your progress. I have known people to keep pictures of themselves in tight fitting, unflattering clothes while very overweight and post those photos on their refrigerator. It acts as a visual deterrent.
One of the best inventions that has come out in the past 15 years was the invention of digital cameras and camcorders. If there was ever a way to see yourself as others see you, then those 2 tools will help you no end. Before the digital camera, people would be very embarrassed to take in photos of themselves showing their unflattering fat to be developed at the local photo finishing place.
Use your digital camera as a tool to help you lose weight. You might surprise yourself and find out it works.
