Body weight X 10 as a minimum

Options
I felt bad hijacking the nice lady's thread, so I'll start my own.

It keeps being said on here that you should eat a MINIMUM of your body weight times 10 to lose weight.

Do you believe this old adage applies to everyone? Is it a better method of dieting than using BMR or other formulas, or better than elimination diets etc?

Why or why not? ALL opinions welcome.

    I've encountered this guideline before and it works for me as a rough rule. But because I am relatively low weight it means that the 1,200 calorie minimum that so many people keep insisting on here is too high for me. Fitbit usually suggests something in the range of 1,000 for me (I am forced to be sedentary at the moment.) After a month of so-so results I finally lowered the MFP 1,200 max to 1,100.

    Obviously, people on medically supervised diets sometimes eat very few calories; even less than 1,000. Those diets are custom-tailored to provide adequate nutrition and the patients are monitored.

    Right, medically monitored. That is the key consideration.

    FMP recommends that I eat 1880 a day which works out to about 8X my body weight. That is to lose 1.5 lbs per week working out once a week which is about all can average right now. Over the last few weeks I have been losing about 2 lbs per week without any problems and that is with a cheat day every Saturday where I am WAY over that limit. I generally end up between 200 and 400 under what my FMP recommendation is on normal days. I hope to be able to increase the exercise frequency starting tomorrow so that will increase it.

    Thanks. For me (5'6" 135) body weight times 10 almost matches my BMR at 47. But not at 21. And, because I'm quite active (cardio and weights 5 days a week, AND 5+ miles of walking a day) eating 1350 calories isn't terribly realistic over time.

    It also depends on your age too. I'm 63 and can no longer eat all the calories I used to even though I work out every day except Sun. I've always heard that you multiply your IDEAL weight by 10. So for me that would be 1100 (I'm only 5'1"). When I started eating that amount of calories I started to lose. I was trying to do the 1200 as recommended and the scale barely moved. Even at only 1100 cal./day I've calculated that I'll only lose .9 lbs./ week. It's tough but I'm hanging in there. The weight sure goes on a lot easier than it comes off, huh?

    I agree, it totally depends on your age!

    I don't think ANY estimation method applies to everyone. I've heard of people doing 7 or 8 x BW and doing just fine with no supervision, but it depends on the individual.

    I think that in ANY case, TDEE estimation tools are exactly that, estimation tools. You should choose a method and roll with it and adjust based on results. That goes for any method.

    When they refer to minimum, they're referring to BMR. Try not to take it out of context. Body weight x 10 is an estimation, just like BMR is an estimation. If you don't go to extremes, they will tend to be close to the same amount. Extremes being age, body composition, and activity.

    For TDEE, body weight x 14-16 is also an estimate for moderate activity. Once again, if you're not average and tend to be on the extreme side of things, using the regular equations would be a better estimate.

    Most people are getting these numbers from here:
    http://www.bodyrecomposition.com/nutrition/lean-mass-or-total-weight-to-set-calories.html

    Just like someone else said before, these are ESTIMATES. Eat at whatever amount you choose for at least 3 weeks. After you get real-world results, adjust accordingly.

    X10 for loss would put me at ~2150. That's ~150 under my NEAT before exercise. I would gain on 14X.

    MFP has me at 1800 to lose 1 lb per week.

    So I vote no.

    *10 would have me on 2000 kcal. I’ve been eating less than 1500 for most of the last year...

    X10 for me would be about 1,950 calories. I have been losing on 1,550. I would still probably lose, but at a much slower rate.

    That would put me about 500cal above my TDEE and about 900-1000cal above what I’m currently eating to lose. I don’t see how that would work for me at all. I gained weight on that many calories.

    Eh, it's fine enough a place to start as any, if you're eliminating activity factors. All anything should ever be is just that. A place to start.

    Everyone who comes on here, at least to my mind, should learn to pay attention, track what happens, and make adjustments based on real world results.

    I would starve to death on bodyweight x 10 as it would give me a deficit of more than 500 cals a day.

    Current body weight x 10 or goal weight x 10?
    My current body weight x 10 for a calorie goal would not have me losing weight at all but my goal weight x 10 would.

    I followed the calories MFP told me and lost weight just fine.

    Same here I’d die, I’d be in roughly a 1600cal
    Deficit and that’s with out any exercise

    It’s a guideline. Not absolute. Works well for me. MFP’s estimate is crap, from my perspective. Puts me at 1400. F that.

    Before you discount it, here’s some excellent reading on it. https://www.bodyrecomposition.com/fat-loss/how-to-estimate-maintenance-caloric-intake.html/


    Same here except MFP put me at about 1600--way too low for me but 2200 (without exercise, otherwise I need more) has worked very well.

    Remember that the question posed was that it should be the "minimum" someone should eat. Not necessarily the recommended amount. I think some posters are taking the answer and applying it beyond a hypothetical.

    I know it wouldn't work for me either, but hypothetically, as a minimum? Sure, why not.
