Food Weight vs Food Volume-which is correct (so freakin confused!!)
The second factor is caloric intake. This is where weight comes in. If you want to track your calories then this is necessary.
In general, I still use both. Especially when eating out when I can't measure everything. I don't have to break out the measuring cups as often as I'm getting pretty good at eyeballing volume and understanding my level of fullness.
It can be confusing, but it is always best to under eat the volume of your sleeve. You will feel better (too full is no bueno) and you will get used to less being normal. At least that is my experience.
Hope that helps.

Here are some examples:
Egg beaters - volume (because that is how the serving is expressed)
Tuna - weight
Yogurt - volume (usually just the volume in the container.
Meat - weight
Lavash - (I use Joseph's oat and flax) - portion size (1/4 sheet) as that is how the servings are measured.
I can't imagine trying to stuff something like a lavash into a measuring cup

Hope that helps. It gets a lot easier as you go along. You'll begin to see how much food you have on the plate as it relates to volume. For me, my stomach seems about the size of a quest protein bar. Those fill me up to the top without going over. So in my mind, I'm always referencing that as a mental sizer.

blackegi, I usually weigh my food on scale such as meats, veggies, most everything unless it is a liquid then I use a measuring cup. You can consume more liquids at time but I cant see cutting up meat and putting it into a measuring cup as the meat "weighs" more and you world more likely be over in oz. Just my opinion and that's what works for me but everyone is different. Good Luck!

So, for liquids and softer foods you are better measuring volume - i.e. 1/4 cup, or 2oz container. For proteins such as meat, fish and cheeses, you should weigh them. Reason being, 2oz of cooked, ground turkey (for example) may be 1/2 cup. You get lots of protein and not so many calories and importantly, no carbs, but you also risk stretching your sleeve or the bottom of your stomach, or getting food stuck in your esophagus.
I put my container on the scale and start scooping food in. Whatever I hit first - 2oz or the top of the container, that's where I stop.
That's how I have been measuring. I glad to hear that is fine.

It's relative, but that's what I was trying to say about volume. Your sleeve has physical size restraints. Two ounces of something dense and heavy might fit, but two ounces of something fluffy and big might not.
