New Eating Plan?

I've been thinking about my eating plan, and how I've been losing weight at a good pace.  But I want that pace to continue, and I know I'll need to change somehting up.  (Warning, this might be a little bit of numbers.)  I thought about lowering my Caloric intake.  I mean, that's how you lose weight, right?  Well, I crunched some numbers, and it was a little surprising.

Based off an average of 9 different metabolic websites, I burn 2,650 Calories a day (as a sedintary person).  If you count my workouts (just the walking and aerobic exercise) for most weeks, I can add 6,450 Calories burned a week.  This gives me a total of 25,000 Calories a week that I can consume.  Yikes!  If I divide that by 7 days a week, I come up with just over 3,500 Calories a day.  In order to lose more than 3 pounds a week, I need to have a Caloric deficit of 10,500 a week, or 1,500 Calories a day.  So, that leaves me with 2,000 Calories a day I can eat.

A little while ago, I counted my Calories during the week day.  I came up with about 700.  Which would leave me with 1,300 for dinner!  I don't need tha much in one meal.  That's why I'll be adding a little into my work meals.  I think I'll add a can of tuna, and/or and some carrots, celery, or other fresh veggie...maybe some nuts (in extreme moderation).  I'm thinking that I can actually add a little bit of Calories, and maybe my weightloss will continue, and maybe increase.  What do you think?  Any thoughts?  How have you increased your weight loss in the past?

By the way, South Beach Steve just posted an interesting and informative Q&A entry on his blog.  I thought it was a great read.
