So Ive been eating a grapefruit a few times for the past few weeks... however, I just recognized that I seem to have tracked the wrong calories all the time :'(

now i've been looking around in the web, but i cant really find a reliable source for it... every page gives me different information.

I peel the grapefruit and then it sliced... does anyone of you know how many calories 100 gramms of sliced peeled grapefruit have?

    A whole, medium-sized grapefruit will have ~85 calories.

    yeah that's what i've been tracking, but my grapefruit weighs about 250 g and then MFP tells me, that it's 125 cals

    Keep in mind that MFP won't be accurate 100% of the time and predicting the actual calories in a piece of fresh fruit isn't an exact science either. I'd say if you track a default of 100 calories for a medium sized grapefruit you should be good.

    According to nutritiondata.self.com 100 grams of "Grapefruit, raw, pink and red, all areas" is:

    Cal - 42
    Fat - 0
    Chol - 0
    Sod - 0
    Pot - 135mg
    Carb - 11
    Fib - 2
    Sug - 7
    Pro - 1
    Vit A - 23%
    Vit C - 52%
    Calc - 2%
    Iron - 0%

    But there were lots of listing for different types of grapefruit, if you wanted to get more specific about what kind you have. http://nutritiondata.self.com/foods-grapefruit000000000000000000000.html

    Gram weight will be more accurate than using a general size entry (like "medium-sized" or even cup measurements)

    The items listed in the MFP database that do NOT have asterisks next to them (this shows on a computer, but not on the phone apps) reflect the USDA based info.

    I have this problem too. I used to weigh my grapefruit, and log the total grams. Then I realized.. DER, most of that weight is in the peel, and I don't eat that! So i started to weigh it before and after. But whose to know how the information was added into the data base? Are those entries with or without peel?

    I seriously wouldn't worry about a difference of 40 or so calories. That's verging on ED territory.
