this is why *I* usually follow the suggested serving sizes

my boyfriend made (well heated up) a tonys pizza. serving size is 1/3 the pizza but he cut it in fourths. he took half of it, then cut the the other 2 pieces into half, so there was 4. (My daughters needed the smaller pieces.) I ate the 1 piece that was left, and IDK how to log it!

    calculate the calories in the whole pizza and then divide by 8, since you ate an eighth of the pizza.

    You can change the serving size in the drop down menu for the food, Instead of using the 1/3 serving size, use the whole container serving size and then put in .125 for 1/8 pizza that you ate.

    Use a calculator. 1/3 x 3 = total calories for whole pizza. Divide by 8 to get the one piece you ate 9the 1/2 of the 4th)

    Multiply the calories per serving by 3. Then divide that by 4. Divide that by 2 (the half your husband too), then divide that number by 4 (the four pieces he cut the other half into). Then multiply that number by the number of pieces (it sounds like 1?) of that that you ate.

    Ok this is what I do with stuff like that:

    Say a serving is 1/3 for 250 calories, that equals 750 for the whole thing.

    So your BF cut it into 1/4 originally: that would then make each "piece" be 750/4=187.5 calories.

    You said he then cut the remaining to pieces into 2 others. That would then be 187.5/2=93.75.

    This would mean you ate 93.75 calories of that pizza. You would then divide that by the 250 calories it says is a serving. That would then equal: 93.75/250 which is .375 of a serving.

    I see most of the tony's in the database have a 1/3 serving and a full pizza...you could just log the piece as .125 of a whole pizza.

    Or yes you could do this. For some reason it didn't quickly come to me that you at 1/8th of the pizza. hahaha

    So you ate a serving size equal to 1/4 of the pizza?
    The nutrition suggestion is 1/3 so multiply that by 3 to get the whole pizza. Now divide by 4 to get your portion.

    Wow math problems. I was told there would be no need for algebra in real life.

    I got one 1/8 also, but it's not 1/8 of the serving size, it's 1/8 of the whole pizza. So I would do .5 of the serving. I know it's a little off but close enough to move on.
