    "Some people can't or won't exercise. They can lose weight too. Is it better to exercise? Sure. Is it required to exercise?"

    Yes they can lose weight solely by cico. It's not required to exercise to simply lose weight. It's just harder to maintain because once they reach their goal they will gain if they eat the amount of calories allotted for their age/sex/weight. Their maintenance needs will be lower than the average.

    Losing and maintaining are two different processes.

    Exercising is much easier with a smaller body. Someone can lose most of their weight with little or no exercise but that doesn't necessarily mean they won't exercise as they get closer to their goal weight and then into maintenance.

    As for maintenance calories, those vary from person to person anyway.

    Exercise is extremely important when in a calorie deficitbecause without it you can actually lower the rate you use calories while resting. This was proven by a U.S.government study done in 2009. Ci/co works but what good is losing the weight if you're just going to put it back on because you are no longer burning the same amount of calories at rest as you were before you lost the weight?

    May I ask how long you've been in maintenance? 3 years into maintenance here, and I didn't exercise at all during my weight loss phase. My TDEE is spot on and has been since I started this whole thing back in 2012.

    If you look at my profile it is obvious that I am not into maintenance "here." I did however lose 38 pounds about 28 years ago from diet and exercise and did a pretty good job of maintaining it until about 7 years ago. That would put me in maintenance for about 21 years. Of course that was before MFP. Exercise is important during weight loss to preserve our bone mass and metabolism as we get older. If you're happy and your TDEE is spot on then I'm happy for you. Not everyone is as lucky.

    Yes, people keep telling my I'm a lucky freak of nature special snowflake :p TDEE calculators don't ask you your weight loss and exercise history. Many of us here have found these calculators to be very accurate, regardless of our dieting/exercise history. If not exercising during my weight loss phase had somehow lowered the rate I use calories while resting, then why would my TDEE still be accurate? From my own experience my TDEE is very accurate and it's what I go by now in maintenance. I haven't had any issues with my calorie amount being off.

    First you should tell which one is accurate, in your experience.
    If I go to:
    http://scoobysworkshop.com/calorie-calculator/
    and choose the lighest option ("desk job with little exercise"), I get 1660 cal, for maintenance.
    If I go to:
    https://www.supertracker.usda.gov/bwp/index.html
    and describe my activity level as "very light" (lowest option, unless you manually adjust the coefficient), I get 1949 cal.
    If I go to this Italian government website:
    http://sapermangiare.mobi/contoemangio/?pag=dieta#
    and choose again the lighest option, I get 2345 cal, isn't funny?

    Yeah, funny. The first and second give me the same and the third one is a joke since it doesn't even ask for your weight at all.

    I agree about the third being a joke. As for the difference between the first and the second, the difference is in the coefficient.
    Supertracker start from a coefficient of 1.4 for the sedentary level, while scoobyworkshop use a coefficient of 1.2:
    Multiplier My Description Alternative Description
    1.2 Desk job with little exercise Little to no exercise
    1.375 1-3 hrs/wk of light exercise Light exercise (1–3 days per week)
    1.55 3-5 hrs/wk of moderate exercise Moderate exercise (3–5 days per week)
    1.725 5-6 hrs/wk of strenuous exercise Heavy exercise (6–7 days per week)
    1.9 7-21 hrs/wk of strenuous exercise/work Very heavy exercise (twice per day, extra heavy workouts)

    So it ranges from 1.2 to 1.9, while supertracker's coefficient ranges from 1.4 to 2.3 (heaviest option).

    These formulas are very rough estimators - here is an example graph of two leading formulas. If you find them accurate it is just confirmation bias. In every study they only correspond to about 65% of metabolic factors.

    For example, consider women weighing 75Kg of different heights, you'll see that the equations only match at one point and may differ as much as 200 cals (or more).

    Then add the MFP motto of "eating back" your exercise calories. For me, if one is going to count to lose weight, then the TDEE- x% approach seems more logical. Again, assuming you figure out what your TDEE really is. I've never really liked the MFP approach of "eating back".

    There is a thread, somewhere here, about people who lost without doing any excersize and they posted photographs too. In my eyes all of them looked really good. I thought their body composition was very nice, super attractive. Could body composition be a preferential taste for certain body type, rather than an objective standard of what is right body composition?

    Also, my tdee seems right based on my weight loss, from the two sources I used. I've used cico before, lost a lot of weight 75 # and am here losing very well with no excersize, as I did before, with same calorie deficit as I used 9 years ago.

    I have an average life, average activity I think.

    You've had an amazing transformation! I scoff at your "creeping up in age" though. Wait until you're 60, there's no creeping, it's a full on sprint. That being said, I was in my mid 40's when I started really packing on the pounds, now after all these years I'm almost to the weight I was at 40. I couldn't have done this without exercise. Exercise keeps me sane.

    So.....exercise allows you eat more than a sedentary person and still lose weight....ground breaking.

    If you have three children, it might be also that what you consider a "no exercise" lifestyle is actually quite active and full of incidental exercise.

    Even from your graph, the widest point of variation is 1375 and 1475. That's only 100 calories. I don't know where you're getting 200 or more from your graph.

    From what I've read, the Mifflin St Jeor is widely regarded to be the most accurate.

    I like the one posted by @ReaderGirl3 above. http://www.sailrabbit.com/bmr/. For me it's very accurate.

    Exercise is extremely important when in a calorie deficitbecause without it you can actually lower the rate you use calories while resting. This was proven by a U.S.government study done in 2009. Ci/co works but what good is losing the weight if you're just going to put it back on because you are no longer burning the same amount of calories at rest as you were before you lost the weight?

    May I ask how long you've been in maintenance? 3 years into maintenance here, and I didn't exercise at all during my weight loss phase. My TDEE is spot on and has been since I started this whole thing back in 2012.

    If you look at my profile it is obvious that I am not into maintenance "here." I did however lose 38 pounds about 28 years ago from diet and exercise and did a pretty good job of maintaining it until about 7 years ago. That would put me in maintenance for about 21 years. Of course that was before MFP. Exercise is important during weight loss to preserve our bone mass and metabolism as we get older. If you're happy and your TDEE is spot on then I'm happy for you. Not everyone is as lucky.

    Yes, people keep telling my I'm a lucky freak of nature special snowflake :p TDEE calculators don't ask you your weight loss and exercise history. Many of us here have found these calculators to be very accurate, regardless of our dieting/exercise history. If not exercising during my weight loss phase had somehow lowered the rate I use calories while resting, then why would my TDEE still be accurate? From my own experience my TDEE is very accurate and it's what I go by now in maintenance. I haven't had any issues with my calorie amount being off.

    These formulas are very rough estimators - here is an example graph of two leading formulas. If you find them accurate it is just confirmation bias. In every study they only correspond to about 65% of metabolic factors.

    For example, consider women weighing 75Kg of different heights, you'll see that the equations only match at one point and may differ as much as 200 cals (or more).

    Even from your graph, the widest point of variation is 1375 and 1475. That's only 100 calories. I don't know where you're getting 200 or more from your graph.

    From what I've read, the Mifflin St Jeor is widely regarded to be the most accurate.

    I like the one posted by @ReaderGirl3 above. http://www.sailrabbit.com/bmr/. For me it's very accurate.

    it shows just the BMR...

    Yeah, it's a BMR chart that @EvgeniZyntx posted saying it SHOWS as much as a 200+ variation in BMR, between the 2 formulas. It doesn't.

    I really like how this one describes activity levels.

    There is a thread, somewhere here, about people who lost without doing any excersize and they posted photographs too. In my eyes all of them looked really good. I thought their body composition was very nice, super attractive. Could body composition be a preferential taste for certain body type, rather than an objective standard of what is right body composition?

    Also, my tdee seems right based on my weight loss, from the two sources I used. I've used cico before, lost a lot of weight 75 # and am here losing very well with no excersize, as I did before, with same calorie deficit as I used 9 years ago.

    I have an average life, average activity I think.

    I have some before/after pictures in my profile, and I'm very happy with how I look and feel now, especially considering where I've been and that I'm also creeping up in age and this body has carried 3 pregnancies :)

    If you have three children, it might be also that what you consider a "no exercise" lifestyle is actually quite active and full of incidental exercise.

    My youngest is 8 now, so I'm not chasing little ones around anymore :) If anything I spend a lot more time sitting in bleachers watching them play sports lol.
