Weight hasn't shifted on ages, should I log walking?

Hello there,


Bit of a veteran lurker here (3 years). I'm stuck.

I workout about 6 times a week, weights twice, running twice, circuits/power Pilates/trx once and normal Pilates once.

I mix up my workouts (even running can be intervals with speed or incline or just a long jog).

I was wondering if I should be logging my walks to and from work? I'm at sedentary as my fitness setting so I log how far I walk. I've used a heart rate monitor last week and it said I burned 300 calories (about 75 mins). When I don't have the hrm I under do this a bit (I say 60 so the cals are closer at 280). When I walk to the gym that's am extra 20 and from my bf that's an extra 25. This usually has me burning 280-500 cals on walking. I don't eat back. Should this count as part of normal life and be the reason I'm not losing? I have a third protien a third fat (nuts/fish etc very low sat fat) and a third carbs and I've cut out fizzy drinks and refined sugar (mostly, sugar tends to be 45-50g sugar total inc fruit and veg).

I'm going nuts here, I've read so many things and can't work out what I'm doing wrong

Any advice would be appreciated
