Anyone change alot in 6weeks?

I have had success in about 6 weeks -- I have lost about 10 lb and have only another 6-8 to reach my goal, so I didn't have a huge amount to lose to start with. I have kept my calories at an even 1900 every day regardless of exercise and kept up my exercise schedule. The calories were figured by my estimated total daily energy expenditure (TDEE) and taking a percentage off (20%) of that. I can go into more detail if you haven;t read about this method or you can search for the group "eat more to weigh less" and find lots of information there.
