Teaching Physical Education- Calories burned- Does this seem

jlr_12

So, I am a substitute teacher. I set my lifestyle as sedentary, because on the days I'm not working I spend most of the time on the couch (unless I'm cleaning, exercising, etc, but I log the exercise). On days where I am teaching, I noticed I have a much larger appetite..which makes sense, because it's a lot of standing and walking around compared to what I'd normally be doing.

Normally what I've been doing is just giving myself an extra 100 or so calories on the days that I work, since it's hard to log work as exercise and find what was really burned. Yesterday I taught Physical Education, which is my primary teachable, and decided to look it up to see if I could find calories burned, since even when not participating with the class, it seems like a little more walking then regular teaching. I found a Calories Burned by Occupation website that said: 204 per hour when NOT participating in games, and 374 when you DO participate. That seems a little crazy to me...4 hour long classes = 816 calories burned.

I've only been giving myself 100 or so extra a day...unless I do some other kind of exercise after school. Should I be eating even more than that on active teaching days? Anyone else with a similar job that can give some advice?

It's mostly about the deficit. If you are early on in your program, still at a higher BF % (above 35%), and eating 1400-1600 calories a day, then the reasons to increase calorie intake would be to keep yourself from getting too hungry, or to make sure you have enough energy to maintain your workout routine.

If neither of those is an issue, you can just go with the larger calorie deficit.

I am only 5'2 and my the calorie goal MFP gave me is only 1200. Therefore I can very easily find myself under eating. I normally eat all or most of my exercise calories to make sure that I don't net below 1200. That's what my worry is...if according to that site I burn up to 800 calories on days where I'm teaching, and I'm only eating 1300 or so, I'd be well below a healthy amount with only a 500 calorie net for that day. What I'm wondering is if that estimate of calories burned seems high to anyone...if anyone has actually worn a HRM or something of the like during a day of teaching to see what they really burn...and if I should be eating more of those calories back. It's just so hard to get a precise measurement of what is burned, but I am worried I'm not feeding my body enough on those days.
