The arithmetic of weight loss, as of 10/12/07

No gimmicks whatsoever here.

My current weight: 245

Current number of calories to sustain my present weight, as 57 year old man, 5’11”, 245 pound male with “moderately active” (3 to 5 workouts a week): 3,271 calories

Current daily calorie target: 1,750 calories

Weekly calorie “deficit”: 1,521 x 7 = 10,647

Calorie equivalent of 1 pound: 3,500

Projected weekly weight loss: 10,647 / 3500 = 3.04 pounds

Actual weekly weight loss, last four weeks: 3.12 pounds

Is there any clearer proof that it is sticking to the arithmetic that works?
