I know this is a crazy question but I measure all my food, and I am confused as to how I should measure in regards to eggs. I use 2 servings of eggbeaters which is 1/4 cup of eggbeater and 1/4 cup of low fat cheese. This should equal 1/2 cup total but when cooked it fluffs up to seemingly much more. I can eat it comfortably, and the calories and protein are good, but I worry it is greater than 1/2 cup and I might be stretching my stomach. Anyone ever asked this crazy question before?

I think when it fluffs up, that's just air and water. So it's probably fine. But more importantly, I think it takes more food and more time to actually "stretch" your stomach out. I think it's very smart to measure your food, and you'll probably do very well as long as you keep making sure to have reasonable portions.

When air is incorporated into the food (like a scrambled egg) it bulks the volume but not really the weight of it. as you chew you break it down. if you took 4 oz. of solid cheese and grated it, it would appear to be much more, but really isn't. I typically portion out my food in 4 oz. containers. Sometimes even then, I get full quicker if the food is more dense, It's not a scientific answer but it's how I understand it to be. :-)

Thank you both for your answers. I feel better that I am not stretching my stomach. I do measure everything as I do not have control of portions as yet, being only 5 weeks out. I may never have control, as big portions got me to this place, that I needed a sleeve.
