Weight Loss Maths make me cringe
After doing some research, I found that, to reach my goal by January 26th (my birthday), I need a daily deficit of
975 calories, or a weekly deficit of 6825kcal.
My resting/basal metabolic rate (or calories burned a day) at the same site says I'm at 1586 at the very minimum for calories burned in one day.
So...if I eat 900kcal a day (which is my current goal, because I keep BINGING and I gained so much fucking weight...I'm back up to 132 and I want to cry...so...this is trying to not let myself binge D:) then I have a deficit of 686 a day.
So I need to burn 214 calories extra every day that I don't go to the gym.
And on days when I do go?
I burn about 2393 total. Meaning I have a deficit of 1493kcal for the day (that's the calories burned during exercise, plus the calories burned just doing daily activities).
So, if 1 pound is 3000 cals, and I go to the gym about 4 times a week, then my weekly deficit should be something like 8000kcal, right? So I should be able to lose at least a pound a week?
Only it doesn't happen that way.
Why can't weight loss be pretty and mathematically accurate?
Or why can't I at least stick to only 900 cals a day and stop shoving my face full of fat?
