November 21 goal expectation

Today I weighed in at 347 pounds. I started at 413 on August 3rd. Clothes adjustment three pounds. Total weight loss at this point 63 pounds. That's 86 days with an average of .75 pounds lost per day.

I would like to lose 25 pounds by November 21st. Roughly, that's one pound a day. I should weigh in at 322 by my flight to NYC. Remember; seats are only 17" across. I won't be bouncing around the seat, but I should fit.

Benchmarks
November 4th = 340
November 8th = 335
November 12th = 330
November 16th = 325
November 20th = 320
November 21st = enough to fit in seat I hope

How will I get there? Serious diet control and 2 miles five times a week.
