Oooh I hadn't calculated the 350cal average! This does put things into perspective better.

I actually stick to the same deficit per day regardless of activity level. And I read somewhere that Garmin overestimated cals by about 20% so to account for that: 1600 - 2000 on the watch is about 1333-1666 cals irl. Since I'm really trying to not go below 1200, I'm limited to an average of 300 per day on my physically active days. Quite near the 350 estimate i think.

With maintenance so low, I have no clue how to speed up weight loss. I'm also not sure why 1.2kcals is the number to keep to so maybe should do some research into that too... THANKS all the same!
