This may seem like a really dumb question. When measuring 1 cup of food, do you measure in a measuring cup or do you use a kitchen scale and measure 8 oz?

I use a measuring cup. 1oz volume is different then 1oz by weight.

So a cup of lettuce isn't very much, and then when I put my shredded cheese on it and cherry tomatoes, and turkey. That would end up being more than a cup.

I use a cup... I am not sure about the lettuce..... my Dr. told me no lettuce until I am 1 year post op. I do eat other veggies and measure with a cup.

I measure by volume, not weight, since my stomach's capacity is based on volume rather than weight.

I was cleared for iceberg lettuce at 4 weeks and other veggies at 6 weeks and haven't had any issues. My surgeon told me that you can eat more vegetables, especially lettuce, than dense Protein by volume since lettuce is mostly Water. You need to make sure to chew very well of course. I have found this to be true--I can eat maybe 3 to 4 oz of Beans or soy protein, but I can eat a cup (8 oz) of veggies, maybe a little more if it's mostly lettuce.

I use both depending on what the item is and its serving type is. If its meat or some other solid food I use a kitchen scale but if its soups or liquids I use the liquid measuring cups. It makes it easier to compare against recommended servings and track my intake that way.
