IIFYM vs ScoobysWorkshop

DD265

I used IIFYM to calculate my recommended calorie intake, and it feels like a lot (to eat, I mean). Admittedly I've not started religiously tracking/weighing everything yet but I only exceeded it yesterday with a trip to McDonalds and I wasn't an angel for the rest of the day either; still in holiday snacking mode. Scoobysworkshop is giving me very different results, and now I'm not sure which to go with.

Originally I figured I'd stick with the original IIFYM numbers for January to see what happened, now I'm wondering whether I treat the two numbers like a range, or maybe if 1900 calories is too many, I see what 1550 feels like and if I'm satisified, I go with that. Can I have some thoughts?

Currently starting at just under 200lb
Goal is approx 126lb
I estimate my body fat to be in the 40-50% region - I have rolls on my back
I have a desk based job
My workouts are not intensive at this point so I haven't factored them in

IIFYM
BMR - 1618
TDEE - 2258
Target - 1870

Honestly, I’d start with the 1870. As you get smaller, you’re going to have to lower that number to continue to lose. Another option is to determine what maintenance calories are for your goal weight, and just eat that. Then you’ll never have to change your target.

How does this compare when you include daily life and different levels of exercise?

Just TDEE Please spreadsheet - better than rough 5 level TDEE charts from 1919 study.

And workouts don't have to be intense to count.
Walking at about 3.5 mph burns as much as weight lifting with set, reps, and rests.

Sure that walking counts if regular and more than a few minutes.

It's almost identical to IIFYM. As I build up exercise I will factor that in.

Thanks both, I'll stick to the 1870 initially and see how January goes.
