    Hello everyone I'm still a bit confused and this TDEE BMR stuff...
    my bmr is 2026 and my TDEE set at little excercise is 2426 but when i set it at moderate (3-5hrs a week) its goes all the way to 3133. so that gives me an extra 700 ish calories a day it says im burning, but if i workout 4 times a week for about 1.5 hours i know i burn around 600 calories (HRM) so I feel like the TDEE is giving me credit for way more calories than I actually burn and I wont be having much of a deficit.

    Can anyone help explain this to me? Thanks in advance =]

    Please give me your weight, height, and activity level. :)

    I am using MFP and FitBit to track my activity level. I am logging non-normal activity levels in MFP (walks, Bike rides, etc). I have been mostly sedentary(except on the weekends) Right now I am lucky if I get my 10,000 steps;though I am trying to find little ways to increase my activity over the day.)

    stats:

    41 yo
    69 inches tall
    229 lbs as of last weigh in
    31.1 % BF according to Military Method.


    I want to still track my exercise and steps using MFP so I am using the Sedentary settings. I have no issue with eating back calories if needed(for now). If I go to Scooby's site and input my numbers i get:

    BMR=1919
    TDEE=2303
    Cut 15%=1957

    That calcs out to .7 lbs per week; I would really like to lose more than that a week.

    I am trying to walk or ride my bike 3-5 times a week for at least 30 minutes.

    Any help or suggestions would be greatly appreciated. I have been working on this since early April. MFP set me to 1430 and I have been eating back calories, not all of them in some cases but at least over 1430 and still green. There have been days that I go into the red less than 100cals...I have lost about 12lbs so far, but I have plateaued for the last 3 weeks.

    Okay Your TDEE is 2346
    you're BMR is 1955
    Your CUT is 1994

    How many people do this is they slowly raise their calories to eat their 15% cut, which for you is the 1994. Some people raise all the way up to maintenance (TDEE) which for you is 2346 and eat that for 4-6 weeks and THEN eat their CUT. It's up to which you want to do. Just make sure to at least NET your BMR at the end of the day. Yours is 1955.
    Count cals, eat healthy, and at least net BMR.

    Oh wow I seriously had my count off...did you figure that on sedentary or lightly active? Gosh that seems like a lot of calories compared to what MFP has me at, they have me eating 1280 a day? Thank you for taking the time to give me that information, I do appreciate it very much.

    I used sedentary. :) Yes, it's a lot, but after a few days you'll get used to the added bulk of food. I literally eat all day long. Just graze on nuts, avacados, chicken breast, green veggies, sweet potato, I throw protein powder in my greek yogurt, oatmeal, and cereal (I eat Kashi cereal only). Good luck :):) Just keep your diet clean and healthy.

    Ok, so there's quite the difference in my calorie burn on days I work out/run and days I don't. Of course, it depends on the day.

    My question: On days I do work out, my cal intake needs to be 1978 (or so) according to the information in this group. (and why am I suddenly confused... I don't have to NET that amount, right?...just eat that amount?). My 2nd question..(and original question) is on days I DON'T run, I just have to make sure I net my BMR, correct (cause I normally walk 3 miles over the course of the day)?

    Am I on the right track?

    okay, so i think i'm taking the plunge and adding more calories. a little background info: i've lost 70lbs SLOWLY over the past few years. i'm no longer overweight, just jiggly!! i'm looking to tone up, especially in my stomach which is where i've kept the remaining part of my weight no matter what i do. i'm willing to give eating more a try as i've tried everything else and just stayed the same.

    my stats are:
    5'7", 143lbs, female
    i work a desk job, and workout usually around 5 times a week, with burns ranging from 250-900, depending on what i do.

    i've calculated my numbers to be:
    bmr- 1463
    tdee- 2267
    cut value- 1927

    taking what i've learned i think i should be setting my calories at 1927, and eating back any calories burned above 464.

    my main concern is that i'm only eating 1200 calories right now... on monday of this week after gaining 2lbs over the past 2 weeks, i decided to up my calories to 1350, but i'm having a hard time even meeting that without going over a ton on carbs it feels-and that is mainly with fruits, yogurts, and veggies, i'm not chowing down on bread constantly. how quickly or slowly should i move into eating this many calories? and how the HECK do you guys eat this much? :noway: any insights or advice is much appreciated! thank you!! :bigsmile:

    You should aim to eat your TDEE - 15-20% cut EVERYDAY. But if for some reason you can't, you need to at least NET your BMR. It's important to keep your intake very consistant and by doing the math with your activity level, your caloric burn is already factored in with the cut, so eat that CUT amount as often as you can.

    I posted below in another topic, I think this may be the right place to post, copied below, any thoughts would be great:-)
    Thanks

    I am new to group-or new to posting in group;-) I am so confused about the numbers! I have always ate even while losing-1600-2000 cals-love to eat(never starve). I saw the post this am about eating more on boards. I agree you need food. But I did the calculation at fitfrog and was shocked, I eat more than I am supposed too. Unless I am doing it wrong.

    If you would be so kind to look at #'s.

    info-Lift heavy 2-3x week
    cardio 2xweek or mainly biking or something I enjoy to get my heartrate up.Not a fan cardio. All other days, walk dog,garden etc
    47 age
    5'3
    115-117 weight-maintaining for a year-don't want to lose weight,just fat and gain muscle. The scale # is not that important to me, more muscle and strength.
    TDEE 1911 - 15%=1624 I eat more now,this part is confusing?
    BMR 1233
    Any input on this would be helpful? If this is correct I need to eat less;-) or calculate better:-)

    Keep in mind the calculator is an estimate. To get a truer figure you would need one of the body media devices. So if you were losing at 2000 then start eating 2100 and see how you trend. Eat it consistently for 4wks and see what happens, if still trending down, then add another 100.

    YES! My bodymediafit tells me I burn between 2700-3000+ cals where as the calculator told me 2600. I've only worn it for a week so I'm waiting to find my 'average'.
  • Hi, hoping eating more is the solution to my 10 week plateau. I have lost 60 pounds over a period of a few years by the traditional 1,200 calorie diet and exercise. It is no longer working for me. I currently and training for an 8 mile race and going to the gym for weights and cardio 6 days a week. I average about 2-3 hours of working out every day and have not seen weight loss or inches since 3/16/12. Calorie burns between 600-1100 depending on workout based on HRM.

    Here are my BMR/TDEE Calculations:

    BMR:1374
    TDEE: 2131
    So that would make my CUT:1812
    (So I would make sure to never eat below 1812)

    At this point I am willing to try anything, I know that I don't want to live on a 1,200 calorie diet the rest of my life! I am getting married in 100 days and want to lose a few pounds and tone my arms and back! Feel free to add me, looking for advice and support on this new journey. Thank you

    Im confused
    Im female 42 5ft 2in 202lbs I do 6 zumba workouts a week my exercise calories are average 600 a day
    See I have set my TDEE as 3-5 workouts a week as I mainly do zumba and walking although its 6 days a week its not intense as I feel it would be intense if I was running lifting etc

    Do I eat -20% of my TDEE GROSS or NET?

    Take today my TDEE -20%i s 1785 Cal
    Exercise = 900 calories

    Do I eat 1785 Gross or do I eat a cetain Net amount?

    Thanks?

    If you are burning that many cals you need to eat more. You want to eat your GROSS TDEE for 4-6 weeks. EVERYDAY. then after 4-6 weeks you then eat your CUT. Just make sure to ALWAYS at least NET your BMR.

    The way I started was to aim to NET my BMR. :) I'm still in the process of upping cals myself.

    ok, think I'm going to take the plunge here....Lost 12lbs since the beginning of the year, but it has slowed WAY down and I'm eating about 1200 calories a day, per MFP.

    Stats: 5/3-5/4, currently 138lbs, goal of 120
    Desk job, but work out 3-4 times a week, total of about 3-4 hours (elliptical, circuit training class, step class, and then elliptical/outdoor vollebyall)

    BMR seems to be aroud 1400-1450
    TDEE is 2200
    15% cut is 1870.

    So I'm supposed to eat 1870 calories a day unless my workout burns more than 330 calories? That's what makes me nervous.....right now my workouts (minus volleyball) all 'say' they are close to 470 (for the classes) and about 420 for the elliptical. But I don't know how accurate that is....

    And my head is so set on cutting 500 a day, that it is hard to imagine only cutting 330 and eating almost 1900 calories! Someone tell me this will work!

    ashfuse Posts: 224 Member
    You can do that but it's more effective it you eat your TDEE for 4-6 weeks and THEN eat your cut for a few weeks and then go back to TDEE so your metabolism doesn't get used to eating at Cut. Repeat. Eventually your body will understand what you are doing. You just have to be patient and remain in control.

    I guess I'm still confused - am I trying to net just above my BMR (1450) or my TDEE? (2200)

    EAT close to your TDEE and NET AT OR ABOVE your BMR
  • kalynn88
    kalynn88 Posts: 5 Member
    sorry, I must seem really dense - but that confuses me! because isn't the TDEE already taking into account my workouts?

    If I'm supposed to start off the first 4-6 weeks at TDEE, I said I'm moderately active. That's in my TDEE. So I should ALWAYS be trying to eat at my TDEE.

    ok, from your post, I'm getting that I eat close to 2200 calories, and then subtract my workout. If working out drops me below my BMR, I need to eat it back. I get that - but I thought the TDEE already accounted for working out, so that would mean I'm double-counting it if I subtract it again.

    Welcome to the group!

    You're right. TDEE does account for working out, and if everything is calculated correctly, then you *won't* net below BMR, thus you won't eat back any exercise cals. But that's why you are keeping an eye on it at first. Because if you are eating 2200, yet burning 900, then you will know that your TDEE was not calculated with the right activity level. Because your TDEE is only figuring in you burning 750 (2200-1450=750).

    So you shouldn't really have to eat back cals. It's used as a measuring tool. If you have a crazy high burn like 900, once in a while, then you just eat back 150 to make sure you net BMR that day. But if it happens 8 days in a row, or something like that, lol, then you need to recalculate. This tip really comes in handy when you go back down to your deficit, in which your daily burns are only figured to be 420 (1870-1450=420). :wink:

    Did I make any sense, lol? :huh:

    I've given myself a headache reading for the last hour. And I know I'm asking questions that many other have asked already. I had been eating my NET BMR for 3 weeks, gained two pounds, then realized I had figured it out wrong and wasn't eating enough and on exercise days I was eating way too much - but still under TDEE. I increased my calorie limit in MFP to 1917 last week - now I'm aiming to eat 1917 per day, whether I work out or not. I"m watching my NET too - to make sure that I am above my BMR every day. I've gained two more pounds.

    Two weeks ago I was on my bike or working out with a DVD 6 days, this week was only 4. I was a complete idiot and ate back my exercise calories last week, thinking I needed to NET my TDEE cut, but it only works out to 800 calories extra in total.

    1. I know that consistency is key . . . will EM2LW still work for me within 100 calories above or below my TDEE cut?

    2. Some weeks I am exercising an hour a day 6 days a week (strenuous level, I guess, on scooby) other weeks it's only a moderate level. I figured my calories based on a moderate level . . . leaving them at that level will I make up the difference in a strenuous week by watching my net and keeping it above my BMR?

    3. I'm hoping both gains were water weight from increasing calories each time - but it doesn't seem to be leaving. My waist measurement is up about a half inch, everything else is the same. I can attribute a pound to TOM coming up, but I don't usually gain more than that. I totaled my calories for the last two weeks and ate a total of 1800 calories above my TDEE. Is it possible I'm gaining back fat at that level?

    4. I never did a full metabolism reset, I was netting 1650 calories a day before starting EM2LW, so didn't think I would need to. Maybe I do need a reset?

    Thank you all for your answers and your patience.

    I have been reading the posts on here, I read about 5 pages of replies trying to figure out my own situation but I can't seem to get my mind around it.

    I have been on MFP for 5 weeks now and have lost 8 pounds in the first 3 weeks but now it has stalled. I have been eating 1490 calories plus eating back my exercise calories but I noticed in this last week or so I have been netting too low so I found this group.

    I am 28, 5'5, 189 lbs. I am a stay at home mom and now I am doing Ripped in 30 5 or 6 days a week.

    I put in the calculations on Scoobysworkshop.com/caloriecount and got the following:

    BMR - 1645

    1 - 3 hours light exercises -

    TDEE - 2262
    15% reduction - 1922

    So if I understand I am to eat 1922 each and every day (whether I work out or not) and I only eat back exercise calories if I net below 1645.

    I have ordered a HRM so I can accurately calculate my calories burned but I don't understand how to put this information into MFP (including exercise) and how accurate can this be as I'm sure calories burned from day to day will change.

    Correct me if I'm wrong but couldn't I put my activity level as sedentary:

    TDEE - 1974
    15% reduction - 1678
    and then eat back my exercise calories on the day I work out according to my HRM.

    Again I'm sorry that this has been asked over and over again but I can't figure out what will work for me.

    Well, I tried to delete/edit my above post . . . but it's not letting me. So I'll just write an update. Please ignore the above post by me. I've continued to do a lot of reading and chatting with other members of this group. I somehow missed that I really need to do a full TDEE (maintenance) reset. So I've just raised my calories to TDEE level as of today. My goal is to eat at that level every day. The only time I'll worry about eating extra calories is if I don't NET my BMR that day. Like today, I took a 3.5 hour bike ride and burned 1200 calories. And have to eat 1000 of those. No problem, I'm having steak, potatoes, veggie for dinner, a cocktail with a friend and had a big glass of milk with my snack. I've missed milk! I've set it in my calendar to do this for 8 weeks then go back to my TDEE cut value. It only makes sense, I need to reset my metabolism - reteach my body what my maintenance intake is supposed to be, then cut the calories to lose weight.

    and then eat back my exercise calories on the day I work out according to my HRM.

    Again I'm sorry that this has been asked over and over again but I can't figure out what will work for me.

    I'm trying the same thing but am assuming a "light" exercise instead of sedentary to account for walking the dog, going up and down stairs, etc. My stats:

    Age: 35
    Height: 5'5"
    CW: 167.7
    TDEE: 2100
    Cut: 15% 1785

    I figured I would try Netting my Cut since I don't exercise every day. I'm nervous - not sure how it will work out. I had a hard time understanding all the gross/net/cuts and how you were supposed to figure out your TDEE when you don't exercise every day. We'll see if it works out.

    Any suggestions from people who've tried this method would be greatly appreciated!

    Metabolism raises or lowers to meet your eating levels. So, essentially, those were all "maintenance," seeing as your body adjusted to a certain amount of cals, and plateaued. We hit plateaus at high or low levels, so when we under-eat, our body responds by lowering metabolism to meet it, giving us a lower "maintenance." once the body adjusts to that level, anything that we eat above it will be considered surplus. Until we continue to eat that amount consistently, then the body adjusts to the new level and *it* becomes our maintenance. So, when a person undergoes a metabolism reset, it's usually recommended that they get the cals as high as possible, and allow the body to plateau at the higher amount. Weight gain is an expected casualty during this process. Once the body stabilizes at the new level, cals can be lowered, and loss will re-occur at higher levels than before. Then the person is recommended to take diet breaks (a week of maintenance eating) every 12 weeks or so throughout the duration of their weight loss journey in order to prevent it from re-occurring.

    So the weight will fluctuate, but you have to ride it out until it stabilizes, or at least a month or two, so that when you lower cals again, you will begin losing.

    Also, if you've always fluctuated 2 lbs or so, then that is just your natural trend. Maintenance still involves fluctuation. You never actually stand completely still.

    Also, the author of the the above blog, Leigh Peele, has a book called the Metabolism Repair Manual. You may want to look into it, as she goes in to much more detail than I have here.
