Volume Vs. Weight.

 Ok so now for the second time someone has mentioned that their NUT or doc has them only go by volume instead of weight.  And I don't get it.

Say that they are saying we don't want you to have more than 1/4 cup of chicken at a time.  Well if I shred that chicken I can fit a hell of a lot more into that 1/4 cup than I can if it's in 1" cubes.  So weighing is, to me MUCH more accurate of exactly what you are taking in.  Plus how exactly do you know how many calories that is?  How much protein?

Another one, on my shredded mexican cheese it says 1/4 cup is = 28g.  So I put what I filled my 1/4 cup measurer and then weighed it.  It came out to 20g.  So that's both less calories and less protein than I thought I was getting.

I get they don't want people stretching their sleeve but I really don't get this.  Of course I use volume for liquids and things (like yogurt) who take up all the space in the measuring cup but for anything where there may be ambiguity, meat, fish, cheese etc. . . I ALWAYS measure by weight.

Am I missing something?

I weigh my meat in ounces. 1 oz is 1oz  cubed or shreaded.

Also, I don't think you can get an exact calorie and protein count. There are so many factors that effect these numbers. I log EVERYTHING I eat. But I look at it more as a round about figure, hopefully very close to accurate. A general idea.

Just my two cents.

 That's my point 1oz of meat is 1oz of meat no matter how it's prepared.  But a 1/4 cup of meat shredded and 1/4 cup of meat cubed is a COMPLETELY different amount.

I don't agree. 1/4 cup is 2 ounces. Does everything that fits in that 2 ounce SPACE weigh 2 ounces?

 I don't understand.  YOu don't agree with me.  Cuz it seems like we're saying the same thing.


ETA: an oz. is always a measurement of weight.  It is not a measurement of volume, I don't care what it says on the stupid measuring spoons or cups.  When it says 1 cup = 8oz it is for water, everything else with a different density will not actually be 8oz to a cup.

I was kind of agreeing yet disagreeing. You said "That's my point 1oz of meat is 1oz of meat no matter how it's prepared." but that 1/4 cup is different. The reason I said I disagree is because 1/4 cup IS 2 ounces but you just said 1 ounce is one ounce which isn't true. I totally get what you're saying because I feel the same way but I wanted to clarify that 1/4 cup IS 2 ounces it is just in volume form which is absolutely not the same as weight. When I asked the question people told me that an ounce is an ounce is an ounce and that was not correct. So I totally agree with everything you're saying except when you said "That's my point 1oz of meat is 1oz of meat no matter how it's prepared."

Then my surgeon is a retard. His paperwork said eat 2 oz by volume.

Edit: The reason I think they do that is because when I weighed ounces of chicken it was a lot more than the volume version of the 2 ounces of chicken. Sometimes I'm surprised by the amount of food there is on a plate when I weigh it. It looks like a lot!

And I'll argue that he is indeed incorrect.  2oz for both volume and weight is for liquids (see links below).  Net. Wt. is for solids things whose volume may be different based and that is a measurement of WEIGHT not volume.  It's a scientific fact.

"Luckily, we already knew that a fluid ounce is a measure of volume, as opposed to a dry ounce (or avoirdupois ounce), which is a measure of weight. "

The concept i think you are arguing is the one that says your sleeve does not recognize weight but volume, therefore volume should be the measure for feeding your sleeve. While we may measure protein, I've seen very few people talk about weighing veggies, they talk about volume i.e a spoonful or two when measuring how much they can fit in.

I totally get what you're saying. I asked the question before and I kept getting the response that an ounce is an ounce is an ounce is an ounce but volume and weight are totally different just like you can have 2 ounces of jello by volume but I highly doubt it's going to weigh 2 ounces. My surgeon wanted me to eat by volume but it was hard to do with meat so I started using a scale.

Btw, you have to guess a lot with what you're getting as far as nutritional value.
