    TDEE is your total daily energy expenditure.

    It's BMR plus a multiplier that takes into account your average activity level.

    BMR (Basal Metabolic Rate) is just the calories needed to keep you alive - basic body functions, cells building, heart beating, lungs pumping, food digesting etc.

    But most of us don't just lie in bed for 24 hours a day so we have to add a multiplier onto the BMR to account for all the other stuff we do... walking around, raising the kids, climbing stairs, playing sports etc.

    If you're usually Sedentary (office job, rarely work out) then your TDEE is typically about BMR x 1.2.

    If you're moderately active it could be BMR x 1.4 or more.

    If you're an athlete it could be way higher.

    To lose weight the best bet is to knock 15-20% off your TDEE and eat that many calories per day. That should give you a nice steady, sustainable weight loss.

    Thank you for the considerate answer-that made sense

    So with my stats: BMR at 1626 my TDEE is 1951 so a 20% caloric deficit is 390= I should be eating no more or less than 1561 calories a day. Correct?

    Eating below your BMR isn't recommended; maybe your deficit needs to be more like 15%

    At 15% -292.65 = 1658

    Yeah :) It puts you above you BMR slightly, so your body can function properly, but also gives you a deficit from your TDEE.

    OK, finally this is starting to make sense! Thank you

    Thanks for explaining that so clearly. I was wondering the same thing.

    ok, so my BMR=1,332

    So, 1,332*1.4=1864.8

    -20% OR 0.2=370.16

    1864.8-370.16=1494.64????

    Net Calories Consumed* and recommended a 1,200 Calories / Day .

    or should I eat less than 1494.64 to loose weight?

    OP: Thanks for posting the question. I wasn't sure what it was either but I didn't want to post a question. This post and the answers have cleared up my confusion. Yay!

    Keep in mind that you do not eat back your exercise calories when using this method and you eat the same amount every day, even days you don't work out :)

    BMR 1332 X AMR 1.4 = TDEE 1864.8 (rounded 1865) 1865- deficit 20% 373 = 1492 eating 1492 calories a day keeps you above your BMR and under your TDEE. Though I think 15% is more realistic at 1588

    1494 is 20% below your TDEE; you would eat this to lose weight. This number takes your exercise and BMR into account.

    I am glad it helped. I was a little :blushing: to ask since I have seen very rude comments from some people on some posts, but that won't help me go no where!
    Have a great day!

    Here are my stats broken down; hopefully this can help too:

    BMR: 1536

    If I do 3-5 hours of moderate exercise per week my TDEE is 2380

    I eat 20% below my TDEE to lose weight, which is 1904

    Not all people can do a 20% deficit, you may need a 15% deficit. If a 20% deficit puts you below your BMR, you shouldn't do a 20% deficit.

    There have been a lot of rude comments lately. It's getting hard for users to post without fear; I hope things simmer down, so we can focus on what's important. It's great that no one has been rude in here!

    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.

    Folks - those multipliers thrown out in that 2nd post are incorrect to use.

    Moderately active, which had no description of time, is for 3-5 hrs of exercise a week, is 1.55
    Lightly active, which is 1-3 hrs, is 1.375.

    These are NOT the descriptions NOR multipliers that MFP uses either, because MFP considers NO exercise in their daily maintenance.

    So don't go confusing the too.

    Here's a better way to save your stats. Spreadsheet in this link, topic in a great group.

    So 6 days a week is NOT Mod Active, that is Very active. Hope you know how to stagger hard and light efforts to actual benefit from all that exercise, besides just wearing out and causing undue stress, along with undereating if you select Mod Active.

    You get Very Active actually, 6 hrs or more weekly.
