139.4 today and my size-4 khakis fit really well! I was really tired today though...gotta get to bed early tonight. Tonight I did 10 minutes on the elliptical and then did a light Zumba class and was really tired by the end.
My second HRM experiment got a little messed up. The timer apparently stops at 15 hours, which I did notice the first time I did it, but the first time it happened it was the middle of the day. This time, it was the middle of the night and so I didn't restart it until I woke up at 6:30. Then after that the timer just seems to go weird so I don't know for sure what my results were, but my best guess is that it was around 3,000. Wow, that's high. I am going to try again, only this time I'm going to start it at 9:30 p.m., write down the calories burned at 9:30 a.m., and then start again for 9:30 a.m. to 9:30 p.m.
I'm boring even myself now. Later!

140.0 today. Felt fine all day until after the gym, but then I felt yucky in the car on the way to Jess' (like I was possibly getting sick and also I had some general gloom & doom feelings) but feel much better now.
I had a salmon salad for dinner and realized my calories were barely over 1,900, so I had some muesli before the gym to bring me up to somewhere around 2,025. At the gym I did Body Combat (felt great) followed by Body Pump (a bit intimidated by a class FULL of people who were stronger than me, but hey, I'm there so I can get stronger!).
I decided to try the HRM thing again only this time I started at 12:30 p.m. Right now it's been running for almost 9 hours and it says I've burned 1,890 already. That seems crazy high, but that 9-hour period was probably far more active than any other part of the day. We'll see...

So I decided to try wearing my heart rate monitor for 24 hours to see how many calories it'd tell me I burned in one day. I started it at 9:30 last night. Then Jess convinced me to do our eight-minute ab routine together (which I did even though I was exhausted and had already done abs in two of my three classes), and then we went to bed.
This morning I weighed 139.2. At 6:30 a.m.! Forget this being my lowest weight on a work day...this was my lowest weight yet, PERIOD!! Yay!!
I felt a bit tired all day today...but nothing horrible. I planned out a 4.5 mile loop to jog after school (in the town where I work for variety), but ended up in a meeting that went so late that it was starting to get dark by the time I could leave. So instead I did an hour on the elliptical at the gym. It was a good strong workout even though I was tired.
So...the results of my HRM-wearing experiment... it's telling me I burned 2,869 calories today! BEFORE I went to the gym I was on pace to burn about 1,900 or so, but then I burned about 900 on the elliptical. My HRM and the elliptical actually gave me very similar numbers. Interesting!
Just to compare/contrast, I googled "BMR," entered my information, and got 1,429 for my BMR, the number of calories my body supposedly burns each day just to keep me alive, excluding all physical activity. Then I did the multiplication for calorie needs (for weight maintanence) for sedentary (1,714), light exercise (1,965), moderate exercise (2,215), hard exercise (2,465), and very hard exercise (2,715). My HRM result of 2,869 was above all of those. Hmm.
This website also had a few suggestions about reducing calorie intake for weight loss:
*Reduce by 500 per day for a 1-pound loss per week, 1,000 per day for a 2-pound loss per week. Do not reduce more than 1,000 calories per day. For the number my HRM gave me, a 1,000-calorie deficit would put me at 1,869 and a 500-calorie deficit would put me at 2,369. This is interesting because, for the past two months, I actually HAVE been losing about a pound per week eating in that range. Hmmmmm!
*Alternatively, try reducing by just 15 to 20 percent "to start," and then decide whether to reduce more. That would give me a range of 2,295-2,439.
A few thoughts:
*I'm a bit hungry eating just over 2,000 calories today. No wonder! I apparently have an 800+ calorie deficit going. But I'm not going to have any more to eat...it's late and I'm tired. But I think I'll be really tempted to eat more in the future.....
*I'd like to try this experiment again and see if I get similar results.
*Knowing how many calories I burn per day would definitely be SO advantageous to me. I could use this information to eat as much as possible while still losing weight (or maintaining, later on).
*The number-obsessed side of me is thinking I could do this every day... but then there's the side of me that doesn't think I should get any more obsessed than I already am. Maybe I could do it long enough just to get a range and patterns for different levels of exercise, and then just use that info. Hopefully pretty soon I'd learn to just recognize how the different deficit amounts FEEL and use that to guide my actions. I actually think that I do so much better with real solid information.
Last night I read the SP article called "4 signs you're obsessed with the scale."
I laughed, thinking that all four signs would be totally me. Well, I was pleasantly surprised. None of the signs they talked about brought up anything negative for me.
1. "You constantly worry about weighing in."
Me? Nope! I LOVE weighing in, and don't worry about it. More often, I eagerly anticipate it!
2. "You weigh in more than once per day."
Their reasoning for this being a problem is that they state that seeing the natural ups and downs over the course of the day would be discouraging. However, for me it's absolutely NOT discouraging - it's educational! I've learned about patterns in my weight over the course of the day, which actually helps me be LESS discouraged! For example, I just about always weigh more on Mondays than on Sundays just because of the time of day I weigh myself. I expect it, so it never bothers me.
3. "You can recite your weight to the nearest fraction at all times."
I like numbers. I teach, among other subjects, MATH. And SparkPeople itself has another article about using numbers to motivate you! Don't contradict yourself, SparkPeople!
4. "The scale determines how you feel about yourself for the day."
I admitted in my blog on Sunday that I felt ON TOP OF THE WORLD because of a good weigh-in that day. But I weighed two pounds more on Monday and had a fantastic day then, too.
The article goes on to recommend weighing in less often or stopping altogether. But why would I ever do that? Numbers HELP! My weight graph is a super tool for me for seeing whether my program is still working. I've already discussed how knowing how many calories I'm really burning in a day will be incredibly useful for making sound diet decisions. And honestly, I feel that the number one reason why SparkPeople has worked for me in losing weight when all previous programs did not is because of the nutrition tracker. Knowing how many calories I've eaten is CRUCIAL for my success. Knowledge is power!
So, I guess to sum it all up, I guess I just have to say I numbers!!!
Wow, am I a nerd or what?!? HA!

141.0 today - this is the lowest it's ever been on a work day (my weight loss would seem more consistent if I weighed myself at the same time every day, but I like to weigh myself really late in the morning when I can so I can see a fun low number.)
I felt surprisingly great all day considering it was a Monday and I'd only gotten maybe 6.5 hours of sleep. My Greek casserole was only so-so...I'd definitely leave the tomato sauce out next time - it didn't go with the other flavors - and I'd add more spices to add interest. I spread my food out pretty well though I wasn't quite able to keep it under 2,000 - with my pre-gym decaf coffee with soy milk I went JUST over. But I think that's OK because I worked long and hard at the gym!
First I went to Body Pump at 4:30, where I'm really trying to increase the weight on my bar whenever I can. It occurred to me to try my HRM calorie counter again, but only after Body Pump ended. I used it during Step Combo and then Zumba. In all I was at the gym for three hours, and only started to feel tired at the very end. I had fantastic energy through most of it and I felt fit and wonderful!!
Anyway, for the two hours of Step Combo and Zumba my HRM tells me I burned 723 calories. Obviously my heart rate was much lower, most of the time, than it was when I was running yesterday. My HRM doesn't give an average heart rate over time though. I'd like to try wearing my HRM for a full 24-hour period and see what the total calorie burn is. Has anyone else tried this?

I did a route today that is very similar to one I've used in the past, only a little longer (was having too much fun to stop!) and backwards to add variety. :) There are good sidewalks the whole route and plenty of activity, though I didn't see ANY other runners. I tied my sweatshirt around my waist after about 15 minutes, and then had my sleeves rolled up for most of the rest. I saw some gorgeous foliage and really enjoyed myself. I wasn't worrying about speed but I did try my heart rate monitor calorie counter for the first time and WOW, it told me I burned 1,255 calories in 80 minutes?!?!!!!!! Who knows if that's true, but if it is, no wonder I get to eat so much and still lose weight, huh?
Here's what mapmyrun has to say:
(Running portion only):
Time taken: 1:11
Total: 6.45 miles
Avg. pace: 11:00 min/mi
My BMI: 22 (woohoo, this is down from 23 the last several times I mapped my runs)
Avg. speed: 5.45 mph (toldja I didn't care about speed. My time taken includes stops for traffic lights, taking off my sweatshirt, etc., and I just wanted to have fun!)
(Run & walking cooldown):
Time taken: 1:20:08
Total: 6.95 miles
Avg. Pace: 11:31 min/mi
Avg. Speed: 5.21 mph
Just like I suspected, mapmyrun's calorie count is FAR lower than my heart rate monitor. But almost 600 calories lower?? I wonder which one is more accurate. My HRM doesn't take my BMI into account, and mapmyrun obviously doesn't take my heart rate into account. My guess is that mapmyrun doesn't realize how high my heart rate was while I was working - mostly in the 160s. I wonder if the true calorie count is somewhere in the middle of the two. Good thing I don't try to calculate my calorie deficit every day...with the numbers off that much, it'd be almost a useless exercise!
PS - Almost 7 miles...WOW! :)
