what is TDEE calculators ?

I have been trying to figure this one out for awhile and this is starting to make since to me.


Going by the runners world website my calculated BMR is 1728



Your Basal Metabolic Rate:

Your BMR is 1728

Total Daily Calorie Needs:

Calories Activity Level
2073 Sedentary
2376 Lightly Active
2678 Moderately Active
2981 Very Active
3283 Overly Active


My goal is to workout 6 days a week if I set my activity level to moderately active to be on the safe side. ( I just started the 30 day shred.. trying to do 2 workouts a day tho)

The calories I would need to consume to lose weight would be 2142.. Is that correct Thats a 20% deficient at moderately active.

how do i find my BMR?

so according to this site http://theskinnyequation.blogspot.ca/p/weight-loss-calculators.html

my BMR is 1129 and my TDEE is 1355 as of today and when i get to my goal weight it will be BMR 1061 and TDEE 1273, so how many calories should i be eating right now in order to lose, MFP has me at 1200 a day, now when i get to my goal weight, how many should i be eating then??

Any help would be great!! Kinda confused on how this works

Because you selected Sedentary level.

If that is indeed true and you don't expect the exercise to come into play, just easy daily life, then use the spreadsheet in this topic.

Get stats filled in, and on bottom right is alternate method for Eating For Future You, which is eating your goal weight daily maintenance, minus a slight deficit so you'll actually reach it.

Since you have little left to lose, that would be best to avoid losing any muscle. Confirm you follow the protein recommendation, since you are doing no exercise to help retain muscle mass.

Yay, it's heybales! I've been reading as much as I can about the "Future You" thing, and the idea makes so much sense to me. However, I have two questions:

1. Should I be using my Katch-McArdle BMR rather than the one provided by MFP, because it is so much lower and takes BF% into account?
2. The maintenance calories for my current weight and goal weight (even adjusted for a goal BF%) aren't that much different unless I change the activity level (currently desk job with little exercise, future me will be in the 1-3 hrs/week category)

I used the scooby workshop calculator for both.

That spreadsheet is awesome, by the way!

1. If there is a decent difference, yes. Why eat inflated calorie goal when you don't need to.

2. So would be the result of the GW TDEE being based on Mifflin BMR, not Katch. If you based it on Katch, and maintained your LBM, nothing would actually change.
So basing it on Mifflin BMR means an assumed ratio of fat to LBM that is avg for healthy weight folks. But right now if Katch is below Mifflin at CW, you have less LBM than expected. Most do when overweight, but if extreme, that means you really want to gain some LBM by lifting as primary focus.
It also means if little to no exercise right now, you really don't want to risk the muscle mass loss if you already have less than expected.

When that combo comes together, the Future You will not give as much deficit as normal TDEE deficit amount. I generally doesn't actually, but it's a great way to learn to eat the amounts you will be eating later, if routine stays the same.

So just depends on what you want to do. Perhaps TDEE Deficit method now, but when you start working out, go to the EFFY method.
