The gears in my head have been turning this week, and I've been scouring my favorite blogs on the interwebs for answers. How can I be running almost 20 miles a week, and yet not losing ANYTHING?!?!?
Yesterday I decided to read one of my favorite blogs [Body By Pizza] from start to finish. Rachel, [the creator of said blog] has lost 113 lbs., and it goes without saying that she's one of my weight loss heroes. She's also recently completed a 1/2 marathon [you know, like we're training for!], so we're practically BFFs, and she just doesn't know it yet. I figured if anyone had my weight loss answers, she would.
While reading one of her posts I found the basic recipe for weight loss. It's something I've known, but failed to acknowledge for the better part of 3 months now. It always goes back to calories in < calories out. I know this, yet I don't follow it, and I've paid no attention to it. Until now, that is. I did the math, and I realized that in order to lose 2 pounds a week [which seems really reasonable, no?], I need to be consuming no more than 1,200 calories a day. Here's the formulas that were posted on Body By Pizza, if you are interested.
655 + (4.3 x weight in lbs.) + (4.7 x height in inches) – (4.7 x ages in years) = 1615 [this is my personal BMR, which is basically the calories you burn just by being]
Next figure out your Daily Activity Level:
Sedentary Physical Activity Level (desk job, other work that entails sitting down for most of the day). If yes, your score is 1.1
Light Physical Activity Level (on feet/walking around for 1/2 the day or more, e.g. stay at home mothers, salespeople, doctors). If yes, your score is 1.2
Moderate Physical Activity Level (on the move all day with a few limited periods of being sedentary, e.g. gardeners, carpenters, mail carriers). If yes, your score is 1.3.
High Physical Activity Level (constantly on the move with significant amounts of physical labor, e.g. construction worker, farm workers, movers). If yes, your score is 1.4
BMR x Daily Activity Level + Exercise Expenditure [how many calories you burn on a typical daily work out] = AMR [2,176 for me]
(daily AMR) x 7 days = 15,235 calories per week [This is how many calories a week I can eat and maintain my current weight]
(weekly AMR) – 7,000 calories (equivalent to 2 lbs.) = 10,948 calories per week [Seems like a lot until you divide it by 7]....
This translates into roughly 1,200 calories a day. Not much, and certainly way less than I've been eating. I've been tracking my food intake daily on Sparkpeople.com, and I tend to run right around 1,800 cals/day. And that's only if I don't blow it by scarfing down extra crap food.
Oh look, it's me... again....
So, I guess I've taken this information as good news and bad news. The good news: There is actually a reason why I'm not losing weight, even though I'm running more than any person ever should. The bad news: I need to eat considerably less if I ever want to lose weight. And obviously, I DO want to lose weight. I need to figure out how people actually live on 1,200 calories a day, and figure out what said people are eating. I need a better plan. Again.
I'm going to be real here. Next week is not the week to start watching calories. I'm going out of town for vacation, complete with lots of drinking and great food. I'm pretty sure vacation is not the ideal time to start eating way less. If I'm able to maintain my weight during my stint at the beach, I'll be stoked. The week after vacation however, [July 5th, to be exact], should be an ideal time to really start watching my intake.
So I'm looking for ideas. What do the skinny people eat? I'll keep you posted on my findings, and please, feel free to add your own!
