Allan (blog: Almost Gastric Bypass), creator of the DDDY Challenge, is a big fan of dietary math.
That's because it works.
So, I started thinking this afternoon (channeling Allan?!) ...
I am currently 269 lbs. Using Allan's math, that means I have to consume 2,959 calories per day to maintain this lovely physique. (269 x 11 = 2959).
If my goal weight is 145 lbs, my daily caloric intake needs to be 1,595 calories (145 x 11 = 1595).
And, in fact, that 1,595 daily intake is what I aim for in the DDDY Challenge. (Allan is challenging us to eat as if we are at goal weight, and it will eventually get us there!)
So, back to thinking ... how long will it take me to get there, if I continue eating like a 145 lb woman?
Let's see. 2959 - 1595 = 1364 daily caloric deficit. Well, if 3,500 calories = l lb., I should be able to calculate this, right?
3,500 / 1,364 (the deficit) is roughly 2.5, so if I stay on this challenge, beyond its two-week length, I can expect to lose 2.5 lbs per week. I think I did that correctly.
My current weight (269) less my ideal weight (145) means I have 124 lbs yet to lose. If I take 124, divided by 2.5 lbs/week = roughly 50 weeks.
Hey, I can be at goal in LESS than a year?!! I must have done something wrong, because that means by mid-October, 2011, I'd be at goal weight. Wow, that just can't be right! Right there is my incentive to stick to goal calories, if ever there was one (assuming my math is correct, and maybe it isn't).
