I lost 40 pounds in 10 weeks

I agree it sounds like a lot too fast. However, I am losing about 2-3 pounds per week on average, with a couple of weeks slightly higher. My first week I lost 10 pounds, so it was a headstart. MFP has me on 1200 calories per day. I either walk or ride a stationary bike for 30-45 4 times a week. I have cut out all sweets and junk food, eat healthy carbs and lots of veggies and two servings of fruit. I eat half a portion when I go out to eat - I automatically ask for a box when the food is delivered so I am not tempted to nibble. The work contest is really a help as I am competitive. I have tried to lose before and did not have the mental resolve, which I believe is key. I can sit at a table with chips and salsa and not eat one, same goes for bread. (Which I LOVE!) I am a real fan of sweet and dropped them cold turkey - I have not had anything besides fruit Popsicles or FF pudding in the entire ten weeks. I am simply determined, like never before.
