Woo hoo! I've lost another pound!
I was going to weigh in Saturday, but after more than 10 days away from the scale, I couldn't resist taking a peek. The weight I am at now represents the lowest weight I've been at in more than three years.
Last night, I reviewed my January-May SP calorie deficit reports. To my surprise, they revealed that my calorie deficit adds up to about 1.3 pounds a week when I believed it should've been at least 1.5. Here are the numbers:
My BMR is 1922. I average 1500 calories eaten a day. I burn an average of 1500 calories a week exercising, for a daily average of 214. It takes a 3500 calorie deficit to lose one pound.
214 + 1922 = 2,136 calories needed to maintain my current weight
2136-1500=636 average daily calorie deficit
636 x 7 days = 4452 total calorie deficit per week.
4452/3500=1.27 pounds a week.
Dang! That means I'm losing an average of 5 pounds a month, not the six I was hoping for. I restarted SP in January and today is the last day of May. Five months x 5 pounds a month is 25 pounds. I've lost 27.
What I've learned from the numbers crunching is that I'm doing what I'm supposed to be doing. My food diary is reasonably accurate; I'm getting enough exercise and I've been consistent over five months. The only ingredient missing is PATIENCE.
My dietitian told me that to lose 2 lbs a week, I'd have to eat 1200 calories a day. That seems like so little food. Now that I've crunched the numbers, I realize she's right. I don't know if I can sustain eating 1200 calories a day. I will need to think about it.
