Does anyone else notice this? On days where I actually take longer, intentional exercise walks, fitbit gives me a WAY lower calorie burn than on the days where I just naturally get a lot of steps throughout my day, without doing any intentional walking for exercise.
I was working from home for a long time and if I didn't do any intentional walks, my steps could have easily been super low, like 1500 per day. I got to my 10,000 daily religiously, and almost all of that had to come from intentional walking. I also did more walking toward the evening hours as that's when I had time to do it. Based on the calorie burn fitbit gave me and the MFP adjustment, I'd often end up with about 100-150 added exercise calories per day.
This week I finally switched back to working in person. I get about 7500 steps just going about my day at work, and most days I haven't had to do any intentional walking to get up to 10K. I'm also getting many steps way earlier in the day than I did working from home. Fitbit is now saying my daily calorie burn is way higher, and I'm getting a 400-500 calorie adjustment from MFP.
I'm certainly not going to eat all that extra, but I'm just curious. Is this some sort of "glitch" or is there actual reasoning/research behind burning more calories walking throughout the day vs. taking an intentional walk? If anything, I would have assumed it would be the opposite- taking a long/intentional walk would burn more than just walking as you go about your day. Or is there something behind getting the steps earlier in the day vs. the evening?
