My gift : Excel spreadsheet for BMR, TDEE, CUT, BUILD and ma

I do have a question on my numbers though. My current TDEE difference is 18.3 Mifflin St.-Jeorg and 26.4 Hatch- McArdle.
Acceptable range says +-15. Does that mean my deficit is too high??

Well you can go 'til a 18% deficit - but it's way too big for having it sustainable on a long term basis. 15% deficit mean you could slowly lose weight, accross YEARS without having the feeling on being on diet specifically

However, in putting all my figures in, the Mifflin-St. Jeor (For Women)percentage shows as 39.6%. In reading that the "current difference ....acceptable range is -15%/+15% (???) then I have to move my current calories from 1200 to about 1680 to get that figure to about 15%. Is that what I'm after? Maybe I"m eating too little because I have been at a plateau for almost a year.

Say above, that means you have a 40% deficit -ie - if you were eating 40% more, you weight should remain stable :-)
I can confirm that ON ME ONLY - I had a 60% deficit, weight loss, then plateau for months- today I'm on -10% (meaning I eat 10% above maintenance), the weight seems stable (in fact I'm losing but that's another story )

the "If only: OFF days diff (10:10% under ON days intakes) = 20? what does that represent? Sorry to not comprehend that part....? anyone?

Only usefull for people doing Intermitent Fasting - the deficit during OFF days. No need to touch that value if you are not on IF ;-)

what do you mean by cut

A cut/ build are two traditional phases for BB's : cut : being in deficit in order to lose fat/ weigh gained during the build phase.
The build phase consists in eating a lot more above maintenance to synthesize protieins (eg growing muscles). But there is also a fat gain during that phase. So the cut aims to burn fat and preserve lean mass. Above that BB explanation :
Cut 15% : 15% deficit under maintenance
Build 15% : 15% excess over maintenance

And you welcome :-)

don't hesitate if you want me to add extra stuff (but don't too much, the sheet starting to be larger than my screen ahah)

Thanks - an expert review

LOVE this!! Thanks for creating it and sharing w/ everyone!! I just entered all my info. in and changed my macros....gonna give it a whirl. Quick question~ If my BMR is showing 1403 should I be changing my calorie goal to that? I have read that we should eat at least our BMR daily....I started out at 1200 last year and changed it to 1300 when a plateau hit and it seemed to help get me out of it. Well I haven't lost any weight in over 2 weeks so I just upped it to 1400, hoping it helps. I read a lot about the whole eat more to lose more....it seems crazy but it somehow works.

Nope, not your BMR, your TDEE (or maintenance) and play around. If you want to lose weight, update your MFP goals to be around the "CUT " calories, and don't eat them back
