a question about weighing fruit

Posts: 2
edited November 2024 in Food and Nutrition
When you weigh whole fruit to track (like an apple for example), do you track the weight of the entire thing, or do you weigh the core after you are done and subtract that from the start weight? What are your reasons? I've been tracking the entire thing, but it occurred to me the other day that there's quite a bit left behind when I'm done eating.

Also, it occurs to me that this is kind of a silly question; I'm just wondering what other people do and why :)

    Well, when I eat strawberries, I cut the caps off and eat the rest. I don't weigh the caps and I'd treat any other fruit like that. Would you weigh the peel of a banana?

    I only weigh what I eat but I still have no idea if it's what you're supposed to do.

    My mantra - Conservative with exercise #s ; liberal with food diary = creates larger deficit.

    So to answer your concern I weigh the entire Red Delicious apple (let's say it is 200 grams) and if I throw away the core (which I don't) my diary still shows Red Delicious Apple - 200 grams.

    I weigh the edible part of the fruit. I assume when logging fruit from a database (in grams/ounces) that it doesn't include the peel, core, pit etc. I don't know for sure but hope I am right about that. Regardless I am losing weight.

    If I eat an apple without cutting it up and weighing it, I just enter it in MFP as 1 whole apple. You could weigh the core once you are done and subtract it from the starting weight?

    I prefer stone fruits, but I just weigh the whole thing. I figure it gives me a couple (not many, because fruit isn't really as calorie dense as most of the rest of the food I eat) calories to help offset something I might have undercalculated. :)

    I just weigh/log the whole thing, even parts not eaten.

    I cut it into slices and weigh the slices. Seems to work for me!

    ETA: This goes for more than just apples. I just weigh the part that I eat.

    lol. interesting question.....but in a nutshell, i typically weigh what i eat. apples are 'iffy' though haha......too much hassle to weigh prior.....then eat all but the core, then weigh again.....and subtract the core.......too much hassle lol.....and really, not that big of a difference in calories.......probably talking only 20-50 calories.....with the core 'removed'.....i don't know for certain, but that's a rough guestimate ;)

    bananas, definitely peel, and then only weigh what i eat......

    strawberries, i'd weigh just the fruit, caps removed.....but typically i get the frozen strawberries since they are fresher, and available primarily year round....and are already de-stemmed :)


    lol on the other hand, check out this video......1 minute and 15 seconds.....how to eat an apple "like a boss" haha http://www.foodbeast.com/2013/05/02/so-apparently-weve-been-eating-apples-all-wrong-video/

    now, i've only seen the video.....i didn't read the article completely (on my lunch break atm....) but something that fails me, is where do the seeds go....lol...i hope he's not eating the seeds.....since they contain arsenic lol

    The USDA entries (which the non-asterisked entries in MFP that are the best ones to use are taken from) are based on the edible portion of the fruit (if no skin is an option they will include with and without skin options usually, or I know they do for cucumbers and potatoes). So you would only include the amounts you actually eat.

    I usually chop up my apple and weigh it rather than weighing the uneaten bit. If I want to take it to work in whole form, I estimate the weight of what I don't eat.

    I, too, only weight the part that I am eating. I weight the apple slices, the orange segments, shelled nuts, etc. I feel that I have been very successful and it also really helps in those rare moments (restaurants, MIL house) that I have to guestimate!

    Putting a peeled banana on a scale to weigh it is gross (to lazy people like me who never clean their scale). I just found an MFP entry that said "Banana with skin". You may be able to find whole apple entries too.

    Would you weigh the peel of a banana?

    Yes, or I'd remove the peel, weigh it, and eat it without the handy-dandy carrying case.

    That's what the weights reflect if you are using the USDA 100 gram measure.

    If doing "medium banana" it doesn't matter, but those aren't going to be precise at all. (This may not matter much for many, however.)

    I also weigh my eggs (without the shell!) when making an omelet, but mainly because I get farm eggs that vary a lot in size.
  • Thanks for all the replies! I'm trying to be as accurate as possible, so from now on I'll weigh the edible portions of fruit.

    Depends on the fruit. For strawbs and fruit that needs preparing before I eat it, I weigh only the food I eat. For apples, pears, bananas etc. I can't be bothered with the faff of only weighing the bits I eat, so I log it as 80 g banana, 150 g apples, 200 g pear etc. The more accurate approach would be to only weigh what you eat, but as a number of posters have said, there is no harm in a few grams overestimation :)

    I'm squeezing every available calorie I have to eat. All fruit gets weighed. That which doesn't get eaten because it's inedible gets subtracted from the initial weight to accurately log what I've consumed.

    You're probably only talking about a few calories... Weigh the whole thing, eat the edible part and log it as the whole fruit. That way you have a little cushion built into your diary.

    Technically, you'd only log the amount you ate...

    ...but practically, it's almost certainly inconsequential.


    But if you're a data nerd like me, just weigh an average apple core after you're done and subtract that amount from all future apples logged.

    1. Plate on scale
    2. Tare scale
    3. Weigh naked banana
    4. Nom profits

    I cut up my fruits and weigh what I will eat.

    This. I always sliced/cored apples before eating anyway, so nothing changed except for adding the scale.

    Set a plate or paper towel down first. I never put food directly on the scale.

    When you eat a banana cut into pieces and not from the built-in banana peel holder...



    ...the terrorists win.

    Or weigh the banana with the skin, peel it, then just weigh the peel and subtract it... that way you don't even need to use a plate. I never put any food directly on the scale either.

    The USDA nutrient database estimates the refuse (core and stem) portion of an apple as 10%. http://ndb.nal.usda.gov/ndb/foods/show/2171?fg=&format=Full That seems good enough.

    for bananas, i input "one small banana" and it doesn't give a weight in MFP. for apples, i input "one small" again, no weight. for strawberries, i cut off stems/caps and weigh in grams. i don't really have a reason for doing it, that's just how i've always done it.

    I'm not fussy about logging fruit. I go for descriptions like "medium" or "large".
