    no, sorry. my rmr is only 970. bmr just almost 1100.

    Still have that reversed.

    A test would have been for RMR - Resting.
    BMR - Basal or Basic, would be below that actually.

    So if the test said RMR is 970, your BMR is actually lower.

    If test said RMR is 1100, then BMR may indeed be 970, depending on BF%.

    And those values may be right on and expected for your real Lean Body Mass.

    Then again, they could be over.

    Then again, they could be much lower and suppressed.

    Figure anything outside 5-10% difference is not natural reasons.

    Very clearly explained. Going to go 30% under my TDEE... This means going from 1,300-1,400 cals to 2,236... I'm so scared but I trust this theory!

    30% isn't sliding you right under your BMR? And with exercise you'll be in almost the same boat you are right now?

    Don't shoot your body in the metabolism thinking it'll be better.

    My BMR is 1,853... Multiplied it by 1.725 for Very Active (Insanity 6 times a week) is 3,196 and 70% of that is 2,237. Or do you reckon I should multiply it by 1.55 for Mod. Active (which would be a TDEE of 2,010)? Like I said I do Insanity, but the rest of the day is a lot of sitting, some walking (5 mi) when I have school, cleaning around the house, cooking, but mostly really just sitting down.

Like I said I do Insanity, but the rest of the day is a lot of sitting, some walking (5 mi) when I have school, cleaning around the house, cooking, but mostly really just sitting down.

    How many HOURS, not days, are you exercising a week?
    I thought Insanity was a shorter program.
    You may be rounding up from one level, or down from another.

    So you think you burn more than 383 calories in your session, because for almost every day in a week you'd be under BMR by decent amount, likely making your exercise not nearly as useful as it could be. (2236-1853)
    So that is what your exercise is knocking off your calories purely for mechanical movement, forget desire to improve things.

    You exercise for body improvement, right? If you don't feed it, you won't get it.

    Diet is for weight loss, hopefully just fat loss unless you do it wrong.

    Which for you, 30% is wrong for sure. 20% with better TDEE estimate would be better.

    Or you the spreadsheet several have recommended to you to keep it simple.
