Big Potato, Don't get discouraged. Even if you see no results right now and don't for another six weeks you are still on the path to healthiness. Let me describe what will happen if you keep going. You will feel stronger. Your legs won't feel wobbly when you go up the stairs anymore after commuting. You will start to look for longer routes to work and start taking them. On saturdays you will take a look at you bike and think hmm wouldn't it be fun to take a ride. Foods that you used to eat routinely will become treats that you occassionally indulge. You will be more attracted to fruits and vegetables. Oh and when you stand on the scale you will notice that the numbers on it are lower than they used to be. If you look at this as just a weight loss jag you will probably be disappointed but if you see it as a lifestyle change you will be very happy.
