My nutritionist always told us to measure as in 1/4 = 2 oz. volume instead of 2 oz by weight in grams. That's what I've been doing. Then I find this article:

Fluid or volume ounces or is it an ounce as it weight?

It sounds like you are a newer sleever. Therefore, go with your measuring spoon for now ... It's looking at the volume capacity of your stomach, not how much the item weighs.

After your tummy has healed and you find your stomach is emptying faster, you can start looking at calories and measuring weight. Right now, you really aren't consuming enough calories to be much of an impact.

I know it's all confusing right now, but you will find your way. Until then, feel free to ask away! ;0)

I weighed food that wouldn't fit in a measuring cup--like steak--so I knew how much a portion looked like on a plate. For food that will fit in a measuring cup, I used cups, again so I'd know what a portion size looked like when I'm not at home. But like Mini-Me said, it doesn't really matter for you right now. It will become important for you to eyeball food and know how much you can eat in the future.
