It is possible. Until adding the HRM I really didn't think I was burning that much from what I usually refer to as simple walking. I was going by the count on the treadmill and adjusting it up a little (as it's not weight based, and I'm not average). However, looking at yesterday and comparing it to my estimates there's about 300 cals a day difference. I'm seeing about 300-400 calories difference in what I've estimated and what the heart rate monitor says I'm burning. This is assuming that number is accurate.
I still think that the rest of the time I'm doing little more than baseline burning (sitting at the computer, sitting on the couch, etc.) although now that the weather is nicer that will change. As someone who avoids exercise like the plague usually it's easy to convince myself that I shouldn't do it. So I'm never sure if I'm trying to talk myself out of it or lack the energy to do it. I feel more energetic this morning so I'm at a loss. Can you tell I'm struggling with this?
I think I'm always bouncing between not doing enough and perhaps overdoing it. Now that I have a way of measuring what I'm doing it might be time to consider dropping those levels a little and seeing what happens. The other option is to raise my intake levels (although I'm not sure how I would do this and keep my protein levels up - more protein shakes I suppose). The book calculations, adjusted for weight difference give me:
RMR: 1823
No workout: 2187
Active: 2552
Strenuous: 2916
I've been doing 2200 and 2600, really assuming that my walking M-F is more of a non-workout. I'm not sure that sitting around most of the day and doing 90 mins of walking is considered active. And I think the daily walking (with a little jogging now) is probably good for my heart health, so although I may replace it with some swimming I likely plan to keep it up. Maybe the solution is to eat a bit more. I think that's the hardest thing for someone who has a lot of weight to lose - finding an appropriate level to eat at.
You've given me quite a bit to think about. I'm interested in anyone else's feedback as well.
