Yeah, i find that the best option too with regards to setting activity levels low. I WFH and set it to show that i do nothing, however i generally then eat any additional calories to help fuel my running.
I got back from Spain last weekend and set myself a goal of getting down to 90kg by Christmas. 7kg seemed achievable in 3 months, however almost 2 weeks later and my weight hasn't budged! I was expecting the usual post holiday drop as my diet went back to it's usual levels and without drinking around 2000kcal each day in alcohol. Although i also didn't put any weight on either.
I've probably averaged around 1500 net calories in those 2 weeks too. I suspect the truth is it's higher than that, as unlike Andy above i don't track milk/condiments etc and just assume over the day they'd add up to 100kcal. I also accept that any exercise calories are likely inflated.
Even at a worst case scenario though, i would expect my daily calories over 2 weeks would at most average 2000kcal/day. Given i'm 97kg and 190cm, i'd have thought that cumulatively that would've been sufficient to at least have dropped a small amount of weight!
I'm not overly stressing about it, but it continues to show the body doesn't always do what you expect! Hopefully running 40 miles on Saturday will cause it all to catch up
